摘要

研究了一种基于高速图像采集与处理的多发光目标跟踪技术。采用现场可编程门阵列（FPGA）形成高速Camera Link CMOS相机的图像采集与实时处理系统。通过对图像数据进行开窗、求重心等算法处理

实现对多发光目标的跟踪

并搭建由直流电机驱动、具有两个LED光源的发光靶标进行跟踪测试。测试结果表明:相机输出帧频100 Hz时

运动目标相对于相机角速度达1.93 rad/s

仍可实时跟踪。系统的跟踪能力正比于相机帧频。

Abstract

A technology for tracking multi light emitting targets based on high speed image collecting and processing. Using FPGA to form image acquisition and real-time processing system of high speed Cameral link CMOS camera. Tracking is achieved through window setting and Barycenter algorithm. Further

a light emitting target with two LED sources and driven by a DC motor is built to test the tracking and recognition capability. Test results indicate that

with a camera of 100 Hz output frame frequency

moving targets having 1. 93 rad/s angular speed relative to the camera are still traceable

and that

the tracking ability is proportional to the fame frequency of the camera.
