基于双目视觉的标志点定位系统硬件设计

双目视觉通过模仿人类视觉来获得物体的深度信息,使机器具有从二维图像认知三维环境的能力。针对特定应用场合,建立一种自主设计的反光标志点,通过被动式反射光源发出的光来进行定位。基于双目视觉原理搭建试验平台,分析了系统硬件各组成部分技术特点,通过对系统硬件的特殊设计很好地解决了复杂背景对目标物识别定位的干扰。最后通过距离和角度测量试验,验证系统的精度。

Hardware design of marker positioning system based on binocular vision

The binocular vision directly simulates the manner of human eyes observing one scene from different viewpoints to obtain the depth information of object. This system is for a particular application. The objects positioned by this system are markers which can reflect the light radiated by the light source, so they can be located by the passive reflection. The experiment platform is set up based on the principle of the binocular vision. The hardware components technology is analyzed. The system can find a good solution to the influence of complex background on recognition and localization of the markers. At last, experiments are conducted, which contain the distance and the angle measurements. The results demonstrate that the accuracy of the system is good.
