【摘要】 摄像机标定是姿态测量必要环节,其标定精度影响姿态精度。利用摄像机拍摄圆柱体靶标图像,提取角点,依据图像和标定物间的几何关系,用最小二乘法计算摄像机参数。试验结果表明,标定的摄像机参数与其精确参数相差不大,不影响后续目标姿态参数的解算,因而具有重要的现实意义。更多还原

【Abstract】 Camera calibration is an essential part of attitude measurement,The accuracy of the results of camera calibration affects the accuracy of object attitude.The method of camera calibration based on cylinder target is to capture image and then extract coners. According to the relation between the target and its image,the camera parameter can be obtained by the least square method.The results show that the camera parameter calibrated by the method is similar to its parameter,and it doesn’t affect the object attitude accuracy,it has important practical significance.更多还原
