Abstract  – In the present time, automation and intelligent systems are becoming an important part of daily life, especially in areas like surveillance, robotics, and smart environments. One of the key challenges in such systems is the ability to detect

always suit.able for stud.ent projects or low-budget implementations. With the availability of low-cost hardware such as Rasp- berry Pi and the advancement in deep learning techniques,

and continuously track a moving object in real time. This paper presents the design and implementation of a low-cost vision-based object tracking system that combines embedded hardware with distributed artificial intelligence processing Instead of relying on a single device to perform all tasks, the

it has become possible to design more affordable trac.king syst.ems. However, a major challenge ari.ses when trying to run computationally intensive algorithms on embedded

devices. As discussed in the dissertation , embedded systems

proposed system divides the workload between a Raspberry Pi

Zero 2W and an external processing unit. The Raspberry Pi is responsible for capturing video and controlling the mechanical movement of the camera, while the object detection is carried out using a deep learning model on a more powerful system. This approach helps in overcoming the limitations of embedded hardware, especially in terms of computational capability.

A pan-tilt mechanism driven by servo motors is used to physically adjust the camera orientation so that the object remains within the field of view. The system operates in a continuous loop, where frames are captured, processed, and used to generate control commands. Experimental observations show that the system performs reliably under normal indoor conditions, with acceptable response time and tracking stability. The design focuses on simplicity, affordability, and flexibility, making it suitable for academic projects and real-world applications. Additionally, the modular structure allows future improvements such as multi-object tracking, edge AI integration,

and enhanced control strategies.

  1. Introduction

    Obj.ect trac.king is an impor.tant conc.ept in modern tech- nol.ogy, espec.ially in applications like surveillance syst.ems, auton.omous robots, human-c.omputer intera.ction, and smart monit.oring solut.ions. The abil.ity to det.ect and fol.low a moving obj.ect accur.ately in real time is essen.tial for buil.ding intell.igent systems.

    Traditi.onally, obj.ect trac.king has been implemented using high-end syst.ems such as PTZ (Pan-T.ilt-Zoom) came.ras, whi.ch prov.ide reli.able perfor.mance but are expen.sive and not eas.ily customizable. Beca.use of this, such syst.ems are not

    Iden.tify applicable fund.ing agency here. If none, del.ete this.

    often lack the proce.ssing pow.er requ.ired for real.-time deep lear.ning infer.ence.

    To addr.ess this limit.ation, the sys.tem prop.osed in this paper foll.ows a distri.buted archit.ecture. In this set.up:

    the embe.dded dev.ice hand.les real.-time opera.tions such as video capt.ure and mot.or cont.rol the exte.rnal sys.tem perf.orms obj.ect detec.tion usi.ng deep lear.ning

    This separation allows each compo.nent to perf.orm tas.ks that suit its capab.ility, resul.ting in bet.ter over.all perfor.mance.

    The main objec.tive of this work is to des.ign a sys.tem that is: low cost, capa.ble of real.-time trac.king, sim.ple to imple.ment, scal.able for fut.ure improv.ements. [1], [2]

  2. Literature Review
    1. Traditional Object Detection Techniques

      In earl.ier syst.ems, obj.ect detec.tion was carr.ied out usi.ng tra- ditional image processing techniques. For instance, Haar Cas- cade classi.fiers and Histo.gram of Orie.nted Gradi.ents (HOG) are some of the traditional techn.iques that have been wid.ely empl.oyed in earl.ier archite.ctures. These techn.iques empl.oyed feat.ure detec.tion to det.ect obje.cts in ima.ges. [3]

      Alth.ough the.se techn.iques have been effic.ient in ter.ms of computational compl.exity, they have some limita.tions. For inst.ance, their effecti.veness is larg.ely depen.dent on ligh.ting condi.tions, backg.round, and obj.ect orient.ation. This imp.lies that they are not effec.tive in a dyna.mic enviro.nment.

    2. Deep Learning for Object Detection

      The introd.uction of deep lear.ning has signifi.cantly impr.oved object detec.tion perfor.mance. Convolutional Neural Netw.orks (CNNs) are capa.ble of automat.ically extra.cting rele.vant fea-

      tures from images, making detec.tion more rob.ust and effi.cient [3].

      Two prim.ary appro.aches are comm.only used in obj.ect detec.tion:

      • Two-stage detectors:
        • Examples: R-CNN, Fas.ter R-CNN
        • Provide high detec.tion accu.racy
        • Have slo.wer proce.ssing spe.ed due to multi.-stage com- puta.tion [9]
      • Single-stage detectors:
        • Exam.ple: YOLO (You Only Look Once)
        • Off.er fas.ter proce.ssing spe.eds
        • Suit.able for real.-time applic.ations [4], [5]

          YOLO is wid.ely used due to the follo.wing advan.tages:

      • Proce.sses the ent.ire ima.ge in a sin.gle pass
      • Achi.eves a good bala.nce betw.een spe.ed and accu.racy
    3. Embedded Systems in Vision Applications

      Embe.dded syst.ems such as the Raspb.erry Pi are wid.ely used in vision.-based applic.ations due to the.ir practical advan.tages [7].

      Key advan.tages incl.ude:

      • Low cost
      • Comp.act size
      • Easy interf.acing with sens.ors and periph.erals Howe.ver, the.se syst.ems also have cert.ain limita.tions:
      • Limi.ted CPU processing pow.er
      • Restricted mem.ory capa.city
      • Diffi.culty in efficiently runn.ing deep lear.ning mod.els
    4. Distributed System Approach

      To over.come hard.ware constraints, distri.buted syst.ems are empl.oyed for effic.ient task manag.ement and perfo.rmance optimi.zation [2].

      In such systems:

      • Embedded Device: Respon.sible for sens.ing and act.ua- tion tasks
      • External System: Hand.les computat.ionally inte.nsive proce.sses

        The key bene.fits of this appr.oach incl.ude:

      • Improved over.all sys.tem perfor.mance
      • Redu.ced computa.tional load on the embe.dded dev.ice
      • Enha.nced scalab.ility for fut.ure upgr.ades
    5. Identified Research Gap

      Bas.ed on the literature review, several rese.arch gaps have been ident.ified:

      • Lack of low-.cost solut.ions capa.ble of real-time per.for- man.ce
      • Inefficient utiliz.ation of embedded syst.ems for intel.ligent applic.ations
      • Limi.ted integr.ation betw.een AI-based detec.tion and con- trol syst.ems

        The prop.osed sys.tem addre.sses the.se chall.enges thro.ugh the follo.wing appro.aches:

      • Impleme.ntation of distri.buted AI proce.ssing
      • Integr.ation of embe.dded cont.rol mecha.nisms
      • Use of efficient communi.cation proto.cols for data ex- cha.nge
  3. System Design and Methodology
    1. System Architecture

      The sys.tem is divided into four maj.or modu.les:

      • Vis.ion acquis.ition mod.ule
      • Processing mod.ule
      • Communi.cation mod.ule
      • Cont.rol and actua.tion mod.ule

        The over.all system oper.ates in a conti.nuous loop, consi.sting of the following ste.ps:

      • Capt.ure video fra.me
      • Send fra.me to the processing unit
      • Detect the object
      • Calculate the object position, generate control signal, adjust cam.era posi.tion accord.ingly

        In ord.er to effect.ively man.age real.-time obj.ect trac.king tas.ks, the sugge.sted sys.tem architecture empl.oys a distr.ibuted and modular design approach. A structured data exchange mechanism allows each module to function independently while maintaining synchronized communication. Video fra.mes are contin.uously capt.ured by the vis.ion acquis.ition mod.ule and sent to the exte.rnal proce.ssing unit, whi.ch uses sophis.ticated object detection algor.ithms. Control sign.als are crea.ted and sent back to the embe.dded system bas.ed on the posi.tion of the dete.cted obj.ect. The camera dynami.cally modi.fies its orient.ation to keep the tar.get in the frame tha.nks to this clo.sed-loop intera.ction. In addi.tion to incre.asing sys.tem scala.bility and flexib.ility, the modu.lar archit.ecture enab.les the fut.ure integr.ation of sophisticated feat.ures like multi-object tracking and on-device inference.Additionally, the computational load on the embedded platform is greatly

        Howe.ver, cert.ain chall.enges are assoc.iated with distr.ibuted systems:

      • Communication late.ncy betw.een sys.tem compo.nents
      • Synchron.ization iss.ues during real.-time opera.tion

      decre.ased by empl.oying a distri.buted proce.ssing stra.tegy.

    2. Hardware Components

      1. Raspberry Pi Zero 2W

        The Raspb.erry Pi Zero 2W ser.ves as the cent.ral contr.oller of the sys.tem.

        Its prim.ary functions incl.ude:

        • Captu.ring vid.eo fra.mes from the cam.era mod.ule
        • Send.ing data to the external proce.ssing sys.tem
        • Recei.ving cont.rol comm.ands from the proce.ssing unit
        • Gener.ating PWM sign.als for servo cont.rol

          Key advan.tages of usi.ng the Raspb.erry Pi Zero 2W incl.ude:

        • Low cost
        • Comp.act size
        • Ease of integr.ation with various hard.ware compo.nents

          Apa.rt from its fundam.ental feat.ures, the Raspb.erry Pi Zero

          2Ws low pow.er consum.ption and effec.tive processing power make it a depen.dable platform for embedded vision applica-

      2. Camera Module

        The cam.era mod.ule conne.cted to the Raspb.erry Pi Zero 2W is respon.sible for captu.ring continuous vid.eo stre.ams, which ser.ve as inp.ut for the object detection sys.tem. Typic.ally, the Raspb.erry Pi Camera Mod.ule (such as Cam.era Mod.ule v2 or HQ Cam.era) is used, whi.ch supports high-re.solution ima.ging and stable video capt.ure.

        The camera interfaces with the Raspb.erry Pi thro.ugh the CSI (Ca.mera Ser.ial Inter.face), enab.ling fast data tran.sfer with mini.mal late.ncy. It is capa.ble of captu.ring vid.eo at var.ious resolu.tions and fra.me rat.es, allowing flexib.ility bas.ed on applic.ation requir.ements.

        Fig. 3: Camera Mod.ule

      3. Pan-Tilt Mechanism

        The pan-.tilt mecha.nism enab.les controlled move.ment of the

        tio

        cam.era, allo.wing it to track obje.cts dynami.cally in both

        .ns. The boa.rd facili.tates easy integration with sens.ors and

        horizontal and vertical directions.

        exte.rnal devices by supporting multiple communication inter-faces, inclu

        The main compo.nents of the mecha.nism incl.ude:

        .ding SPI, I2C, and UART. Real.-time commu.nica-

        tion with the external processing unit requ.ires wire.less data transm.ission, whi.ch is made poss.ible by its integ.rated Wi-Fi mod.ule. Additi.onally, develo.pment and debug.ging proce.dures are made easier by the abundance of software libra.ries and commu.nity supp.ort. The Raspb.erry Pi Zero 2W is a good opt.ion for crea.ting scal.able and reaso.nably pri.ced real.-time trac.king syst.ems beca.use of the.se feat.ures.

        • Two ser.vo mot.ors
        • Moun.ting struc.ture for cam.era supp.ort

          The sys.tem prov.ides the follo.wing capabi.lities:

        • Pan: Horiz.ontal rota.tion of the cam.era
        • Tilt: Vert.ical rota.tion of the cam.era

        Howe.ver, cert.ain chall.enges are assoc.iated with the mech- anism:

            1. AI Processing Software

              The AI processing software operates on an external system

              • Mecha.nical jit.ter dur.ing move.ment
              • Limi.ted preci.sion in positi.oning

                Fig. 4: Pan-.Tilt Mecha.nism

                and perf.orms the follo.wing funct.ions:

                • Receives image fra.mes from the cam.era mod.ule
                • Proce.sses ima.ges for enhanc.ement and feat.ure extraction
                • Detects obje.cts using adva.nced algorithms
                • Calcu.lates posi.tion and spat.ial coordi.nates of dete.cted objects
                • Sen.ds cont.rol comm.ands to the conne.cted sys.tem

        GPU accele.ration is util.ized to achi.eve real-time per.for- man.ce and ensure effic.ient proce.ssing of high-re.solution data stre.ams [4], [5].

          1. Communication Protocol

            The system uses TCP communi.cation to ens.ure reli.able data tran.sfer between components.

            The.re are two prim.ary data flo.ws in the sys.tem:

            • Forward Direction: Transm.ission of video fra.mes from the cam.era mod.ule to the proce.ssing unit
            • Reverse Direction: Transm.ission of cont.rol comm.ands from the proce.ssing unit to the hardware sys.tem

              TCP ensu.res that all data pack.ets are deliv.ered wit.hout loss and in the correct sequence, thereby maintaining system

          1. Control Strategy

        The cont.rol sys.tem deter.mines the posit.ional err.or by cal.cu- lat.ing the diffe.rence betw.een the dete.cted obj.ect posi.tion and the cen.ter of the fra.me.

          This appr.oach minimizes sudden jer.ks and signif.icantly impr.oves trac.king stabi.lity and overall sys.tem perfor.mance.

  4. Implementation and Result
    1. System Implementation

      The sys.tem was implem.ented usi.ng the follo.wing compo.nents:

      • Cam.era mod.ule
      • Ser.vo mot.ors
      • Exte.rnal proce.ssing sys.tem

    2. Performance Evaluation

      Fig. 6: Tracking Param.eters

      The sys.tem was tested und.er ind.oor environmental condi.tions to eval.uate its perfor.mance and reliab.ility.

      The key results obta.ined are as follows:

      • Tracking perfor.mance was stable throughout opera.tion
      • Resp.onse time was wit.hin accep.table lim.its for real-time applic.ations

      During test.ing, seve.ral observ.ations were made rega.rding system perfor.mance:

      • Distri.buted proce.ssing signifi.cantly impr.oved over.all ef- fici.ency
      • The sys.tem was able to han.dle mode.rate mot.ion eff.ectively
      • Ser.vo smoot.hing enha.nced stabi.lity and redu.ced abr.upt movem.ents

      Fig. 7: Real Time Trac.king

    4. Challenges Faced

      Some iss.ues were observed dur.ing sys.tem opera.tion:

      • Communication delay betw.een sys.tem compo.nents
      • Sensit.ivity to vary.ing ligh.ting condi.tions
      • Min.or inaccu.racies in ser.vo mot.or positi.oning

        The.se iss.ues were mitig.ated thro.ugh the follo.wing mea- sures:

      • Calibr.ation of sens.ors and actuators
      • Param.eter tun.ing for optim.ized perfor.mance
      • Enhanc.ement of cont.rol algor.ithms and log.ic
  5. Discussion

    The sys.tem demonstrates that effec.tive object trac.king can be achi.eved with.out the need for expen.sive hard.ware. By ado.pt- ing a distri.buted processing appr.oach, the sys.tem effic.iently bala.nces computa.tional load and cont.rol operations, resu.lting in improved perfor.mance and scalab.ility.

    Comp.ared to tradit.ional syst.ems, the prop.osed solu.tion off.ers the follo.wing advan.tages:

    • Low.er over.all cost of impleme.ntation
    • Eas.ier set.up and deplo.yment
    • Grea.ter flexib.ility for modific.ations and fut.ure enha.nce-

    men.ts

  6. Conclusion

    This pap.er pres.ents the des.ign and impleme.ntation of a vis.ion-bas.ed object trac.king sys.tem that util.izes a distri.buted proc.essing techn.ique. The sys.tem was able to effectively integ.rate an embe.dded sys.tem and an exte.rnal processing

    detection models with diffe.rent data.sets or by adding image enhanc.ement feat.ures.

    The sys.tem can be furt.her devel.oped with feat.ures such as rem.ote monit.oring via the web or mobile devices. Hard.ware upgr.ades can also be made to the sys.tem to impr.ove ove.rall perfor.mance.

    With these improvements in place, the system can be

    devel.oped into a more rob.ust and flexible sys.tem that can be used in various applications.. .

    sys.tem to add.ress the limita.tions assoc.iated with embe.dded

    syst.ems. The sys.tem util.izes the Raspb.erry Pi Zero 2W to

    perf.orm real.-time tas.ks, and it util.izes an exte.rnal sys.tem that perf.orms obj.ect dete.ction thro.ugh deep lear.ning.

    The sys.tem util.izes a pan-.tilt mecha.nism that enab.les it to tra.ck mov.ing obje.cts. The cam.era is adju.sted to focus on mov.ing obje.cts. This enha.nces the syst.ems applic.ability comp.ared to oth.er monitoring syst.ems. During test.ing, the sys.tem was able to perf.orm adequ.ately in normal condi.tions. The syst.ems resp.onse time and accu.racy were reaso.nable. The syst.ems abil.ity to util.ize distri.butedproce.ssing was effec.tive in enhan.cing perfor.mance and cost. The sys.tems abil.ity to perform adequ.ately with.out incur.ring addit.ional cos.ts is attri.buted to its abil.ity to util.ize distri.buted proce.ssing. The syst.ems modul.arity enha.nces its flexib.ility and abil.ity to be modi.fied. Howe.ver, cert.ain limita.tions were also exp.erienc.ed, which incl.ude sensit.ivity to ligh.ting condi.tions, minor communi.cation del.ays, and inaccu.racies in the mecha.nical move.ment of the ser.vo motors. This shows that desp.ite the good perfor.mance of the sys.tem, the.re is sti.ll room for improv.ement.

    Gener.ally, it is evid.ent that the prop.osed sys.tem is cap.able of trac.king an obj.ect in real time with the aid of affor.dable components.

  7. Future Scope

Alth.ough the sys.tem is work.ing well in this form, the.re are seve.ral improvements that can be made to the sys.tem in ord.er to impr.ove the perfor.mance and ext.end the capabi.lities of the sys.tem. Fir.st and fore.most, the sys.tem can be made indepe.ndent of exte.rnal syst.ems by incorpo.rating on-d.evice proce.ssing with more adva.nced embe.dded syst.ems or AI accelerators. This will mini.mize the communi.cation del.ays that mig.ht occ.ur in the sys.tem.

Another improvement that can be made to the sys.tem is the impleme.ntation of multi-.object trac.king. The sys.tem is curre.ntly desi.gned to tra.ck a sin.gle object. Howe.ver, if the sys.tem is made capa.ble of trac.king mult.iple obje.cts, it can be used in seve.ral real-.world scena.rios.

The cont.rol mecha.nism can be made even bet.ter by imp.le- ment.ing adva.nced cont.rol mecha.nisms such as PID cont.rol. The PID cont.rol mecha.nism can be used to make the pan- tilt mecha.nism move smoothly. Furt.her improv.ements can be made in the area of robus.tness by mak.ing the sys.tem less sensi.tive to environ.mental factors such as chan.ges in ligh.ting and background noi.se. This can be done by trai.ning the
