基于全局差错能量函数的立体匹配算法
Stereo Matching Algorithm Based on Global Error Energy Function
摘要
Abstract
In order to solve the problem of large amounts of computation in the global stereo matching algorithm,this paper proposes an improved algorithm by introducing global error energy function.It considers global error energy function as the cost of stereo matching,carries out region growing by leaps and bounds and gets the disparity map by jumping to obtain error energy function.The disparity map is smoothed by using average filter and the tolerance coefficient which will affect the size of filtering threshold is set,making it more suitable for human eyes.The tolerance coefficient is selected adaptively for different color and pixel stereo image pairs to get optimal filtered disparity map.Experimental results show that,on the basis of maintaining the accuracy,the improved algorithm can reduce computing time and improve real-time performance of matching.关键词
