Study On Optoelectronic Imaging And Tracking System Based On DSP

This thesis aims at developing an photoelectric imaging and tracking system. This system can achieve real-time tracking to moving object in laboratory. Finally a experiment platform and principle demo platform can be provided for the reserach of the structure and practical application of optoelectronic imaging and tracking system.The theory and technique of engineering application is expounded in this paper.The designer and implementer of optoelectronic imaging and tracking system is discussed in this paper. In accordance with the researching tracking equipments and requirement of system index, the tracking control structure is confirmed: the master-slave control structure. The master-slave control structure based PC and DSP experiment system. The PC accomplish the processing of optoelectronic image collected by *CCD camera and implement the human-computer interface. The real time control of two-dimensional numerical turntable is achieved by DSP experiment system. The communication of command and data between PC and DSP experiment system is accomplished through RS232 communication protocol. According to pulse-torque characteristics of stepper motor of two-dimensional numerical turntable, the adaptive control algorithm is adopted which can achieve high precision tracking control through dynamic changes of the velocity of horizontal axis and the velocity of elevation axis of the two-dimensional numerical turntable.
