摘要
提出并研究了基于环形光电探测器的多目标探测与跟踪技术。首先提出了一种基于6片线阵CCD的环形探测器设计。该探测器中的每一线阵CCD光学系统的光轴均通过探测器中心点,且任意两光轴之间的夹角为60°,形成具有360°视场的环形探测结构;提出了基于目标信号脉宽判据、基于目标信号水平尺度比率的复合判据,研究了适用于环形探测器的多目标快速识别与跟踪算法;建立了硬件实验系统,并进行了功能验证实验,实验结果表明:所提出的环形光电探测器及算法设计可实现多个运动目标的探测与跟踪,在目标机器视觉、虚拟现实等领域具有潜在的应用前景。
Abstract
A new multi-target detection and tracking technology based on circular opto-electronic detector is proposed. The detector with circular structure based on 6 linear CCDs,is firstly developed to achieve 360°field of view. In order to achieve the detection and tracking of multi-target at high speed,the target recognition criterions of Object Signal Width Criterion (OSWC) and Horizontal Scale Ratio Criterion (HSRC) are proposed. As a result,the algorithm based on the two criterions,which is suitable for the proposed circular detector,is developed. Finally,an experimental system,which has the functions of signal sampling,process,and results display,is developed. The detection function of the proposed methods is also demonstrated by using the developed experimental system. The experimental results indicate that the technology offers significant advantages in Detection and Tracking,Computer Vision,etc.
