摘要
以作为游戏输入的双目视觉系统为载体,分析了双目立体视觉系统在此环境中需要满足的一些特殊的约束,结合双目视觉本身的经典约束,构造一种可以同时满足实时性和一定的精确性的图像特征点匹配方法。此方法先使用极几何校正和单应性约束求取图像偏差,然后采用快速匹配算法在局部范围内得到匹配点,充分满足了系统对实时性和精确性的要求。
A new method for matching feature points of images from two cameras of a stereo vision system m the game engine was presented. The main issue is how to meet the request of real-time processing and accuracy of the system. Our method is to calibrate the epipolar constrains and calculate the offset of two image aiong with the constraints of homography. Then we used a fast method to match the feature points in a local area. This method is proved to be real-time and accurate enough to fulfill the request of our game engine.
