摘要
本文探索了一种监控图像跟踪系统,该系统以STM32微处理器为控制核心,将广角摄像头采集的图像送至LCD显示,并分析获取图像的数据,针对常用的直接帧间差分法存在的误差大,运算量大,导致内存问题,影响运算速度等问题,提出了一种图像目标提取处理算法,准确快速计算出目标物体的位置坐标,从而控制云台移动,保证目标处于摄像头视野的中央,解决了在图像处理中误差大、运算速度慢、系统内存不足等问题,以低成本低功耗实现了视频目标的提取跟踪处理.
In this paper, a monitoring image tracking system is explored. The system takes the 5ilVl3Z microprocessor as the control core, sends the image captured by the wide-angle camera to the LCD dis- play, and analyzes the data of the acquired images. For the common direct inter-frame difference meth- od, because of a large amount of error, large amount of computation, resulting in insufficient memory, the impact of computing speed and other deficiencies, an image object extraction algorithm is put for- ward to accurately and quickly calculate the coordinates of the target object position. It solves the prob- lems of large error, slow operation and insufficient system memory in image processing, and realizes the video object extraction and tracking processing with low cost and low power consumption tocontrol the PTZ mobile to ensure that the target is in the center of the camera field of vision.
