基于双目相机的光学高度测量系统

根据双目立体视觉模型,搭建一个实验室专用的高度测量系统。首先使用Matlab自带的工具箱对双目相机进行多次标定,获取实验所需的诸多参数,然后通过立体校正技术建立修正后的世界坐标与像素坐标之间的关系方程。在VS2015结合OpenCV的编程环境下,利用立体匹配算法和视差理论获取目标表面的三维空间信息。最后通过选定同一目标的2个特征点获取其空间坐标,达到高度测量的目的。实验结果显示,该系统能够有效实现真实场景下的三维信息测量。

Optical height measurement system based on binocular camera

According to the binocular stereo vision model,this paper builds a laboratory-specific height measurement system.By using the Matlab toolbox to calibrate the binocular camera to obtain many parameters required by the experiment,the paper establishes the relationship equation between the corrected world coordinates and the pixel coordinates through image correction technology.Under the programming environment of VS2015 combined with OpenCV,the stereo matching algorithm and the parallax theory are used to obtain the three-dimensional spatial information of the target surface.Finally,the space coordinates of the same target are obtained by selecting two characteristic points to achieve the purpose of height measurement.The experimental results show that the system can achieve 3 D information measurement of real scenes well.
