摘要
研究了一种能应用于双摄像机立体视觉系统三维图像再现的标定法.它将四个坐标系下的点通过一系列矩阵进行转换,这些矩阵包括内部参数矩阵和两摄像机之间的关系转换矩阵,同时也给出了各摄像机的畸变参数.在实验中,首先由左右摄像机采集9组国际象棋棋盘的像,然后通过运行C++软件得到上述矩阵,最后通过立体匹配验证了标定结果的可信度.
A method of calibration which can be applied to a two-camera stereo vision system for three-dimensional image reconstruction is discussed. It transforms the points in four coordinates through a series of matrices, which include the internal parameter matrix and the relatively transformed matrix between the two cameras. It also gives the distortion parameters of the cameras at the same time. During the experiments, the left and the right camera collect 9 sets of chessboard, then the final matrices are obtained by running the C＋＋ program. Finally, the credibility of the results of calibration is verified by the stereo matching.
