摘要
针对基于十字的自适应窗口的立体匹配算法对窗口内所有的像素点采用一种权值,在大范围斜面区域精度较低的问题,提出一种基于自适应窗口的多权值立体匹配算法。该算法采用AD和census变换结合的方法计算匹配代价,通过改进的方法多次生成自适应窗口,对于生成的不同窗口赋予不同的权值,来计算聚合代价;采用win-take-all的方法计算出视差图,对视差图进行左右一致性检测来优化视差图,进而得到最终的视差图。实验结果表明,与传统的自适应窗口的方法相比,在不增加计算的复杂度的情况下,该算法提高了匹配的精确度。
The adaptive window algorithm based on the cross adopted the same weight for all pixels.This algorithm leaded the low accuracy in bevel area.This paper proposes a multi-weight stereo matching algorithm based on adaptive window.The algorithm adopted AD and census transform fusion method to calculate the matching cost.The adaptive window was generated several times.Different weights are assigned to different windows to calculate the cost of the aggregation.Win-take-all method is adopted to calculate the disparity map,and performed a left and right consistency check on the disparity map to optimize the disparity map.
