基于TI TM4C123的激光追踪系统设计OA

In response to the problems of easy loss and poor real-time performance of laser target tracking,this paper designs a laser target control system and automatic tracking based on the TM4C123 chip of Texas Instruments.The V831 camera module is used as the target position feedback measurement device,and the two-dimensional closed-loop stepper motor cloud platform is used as the motion output.The camera module communicates with the TM4C main control via serial port to provide real-time feedback on the target point position,and uses PID control algorithm to control the motor output.At the same time,magnetic encoding feedback is used to prevent step loss of the stepper motor and achieve position closed-loop control.The experimental results show that the system has high tracking accuracy and good real-time performance.
