摘　　要：提出了一种基于标定的多视点立体采集系统校正方法,该方法首先通过摄像机标定来获得原始摄像机矩阵,然后对摄像机光轴和基线使用平均向量法、对光心使用极值平均法来得到理想摄像机矩阵,最后利用原始摄像机与理想摄像机矩阵的关系变换原始立体图像到校正后的立体图像.实验结果表明:该方法可以有效降低多视点立体图像的垂直视差,而且校正后立体图像分辨率损失较小.A geometric correction method based on calibrated multi-view 3D system is provided. The method firstly compute the original camera matrix, then compute the ideal camera matrix by using average vector method to the camera optical axis and baseline and using extreme average method to the camera optical center, finally apply the relationship of the original camera matrix and ideal camera matrix to the transformation of the original rnuhi-view images. The experimental results show that the method effectively reduces the vertical parallax of the multi-view image, and reduces the loss of image resolution.
