Design of 2D Target Tracking System Based on STM32

摘要:

为了解决现有目标跟踪系统难以小型化和跟踪速度慢的问题,设计了一种以型号为STM32F103ZET6的32位ARM处理器为主控芯片的二维运动目标跟踪系统。系统包括搭载了高清网络摄像机的二维跟踪云台和以STM32为核心的超声电机双路驱动器。系统通过上位机图像处理识别目标,控制下位机超声电机双路驱动器驱动二维云台跟踪目标。实验结果表明,该系统响应速度快、结构简单且跟踪精度高,云台可实现水平方向0°~360°、竖直方向0°~180°旋转。

Abstract:

Common target tracking systems usually present such problems as big volume and low tracking speed, based on which, a two-dimensional moving target tracking system using 32-bit ARM processor of STM32F103ZET6 as the main control chip is designed. The system is mainly composed of double ultrasonic motor driving circuit based on STM32 and 2D tracking pan-tilt with IP camera. When the target is identified by image processing system, the 2D tracking pan-tilt is drived to track the target. Experimental results show that the system can response in less than 3 ms with a high accuracy, and the pan-tilt can rotate in 0°~360° in horizontal direction and 0°~180° in vertical direction.
