摘　　要：运动目标检测和跟踪一直是计算机视觉领域中的研究重点方向,传统的实现方式大多基于CPU或GPU处理器,存在成本高,开发难度大,灵活性低等缺点。本文提出了一种基于FPGA的多运动目标检测算法,系统由CMOS摄像头、FPGA开发平台、VGA显示器组成,通过灰度变换、帧间差分处理、开运算处理、包围盒操作等一系列图像处理算法,可以同时提取多个运动目标并进行轮廓区域标记。经过仿真验证以及搭建实验平台进行实物测试,系统功能正常,能够对多个动态目标实时检测,验证了该系统的可行性。Moving object detection and tracking have always been a research focus in the field of computer vision.Traditional implementation methods are mostly based on CPU or GPU processors,which have disadvantages such as high cost,difficult development,and low flexibility.This article proposes a multi motion object detection algorithm based on FPGA.The system consists of a CMOS camera,FPGA development platform,and VGA display.Through a series of image processing algorithms such as grayscale transformation,inter frame differential processing,opening operation,and bounding box operation,multiple motion objects can be simultaneously extracted and contour area labeling can be performed.After simulation verification and building an experimental platform for physical testing,the system functions normally and can detect multiple dynamic targets in real time,verifying the feasibility of the system.
