Realization of Real-time Image Process Algorithm in Vision Telemeter System

针对双目视觉测距系统中图像处理的实时性和精确性要求高的情况,在软件设计上采用了“变分辨率”快速配准技术和亚像素级精确视差分析算法以及误差补偿算法,并结合了平滑滤波、边缘提取和二值化等预处理过程.经实验表明这几种算法的采用很好的提高了图像处理的实时性和精确性,实现了实时精确视觉测距.

The image processing in binocular vision telemeter system should have characters of real time and accurate, so the technologies such as changing picture elements quickly matching technology, analyzing parallax accurately at sub-pixels and error-correction, combing with some pretreatments as smoothness filter, edge-detection and two-valuing were applied in software design. The experiment result shows that application of these algorithms can improve the image real-time processing and accurate matching and the real-time exact vision can be realized.
