【摘要】为了获取立体视频,需要知道二维图像和三维物体之间的转化关系,这种转化关系需要通过相机系统的标定来得到。首先介绍了由Li Bo等人提出的标定算法,以及如何使用该标定算法来解决多视点立体成像系统标定的问题。然后分析了该算法在实际使用过程中常常产生较大误差的原因,并给出了解决方法。最后的结果表明,通过规范化的操作就可以获得预期的标定精度,并有效地节省算法的操作时间,从而能够满足多视点立体成像系统的标定要求。更多还原

【Abstract】 In order to obtain the stereo video,the transformation relationship between two dimensional images and three-dimensional objects should be known,which is determined by the calibration of the camera system. First,from the introduction of calibration algorithm proposed by Li Bo et al.,how to use it to solve the problem of calibration for multi-channel stereo imaging system is introduced; then,the causes for the error of the algorithm in practice are analyzed,and the solution is given. Results show that the standardized operation can make the calibration result meet the expectant accuracy,and effectively reduce operating time as well,so that it can be more compatible to the multi-channel stereo imaging system.更多还原
