| 中文摘要 | 提出了相机内部参数和外部参数分步标定的方案,通过数理统计法得到了测量的不确定度,分析了用于交通事故现场的摄影测量的精度。实验结果表明:标定点的设置及标定物的摆放应使标定点便于识别和准确定位,而标定物的放置位置对测量结果无显著影响;实验中10m范围的摄影测量误差小于1.5%和50m范围的摄影测量误差小于2%的概率都不小于99%。; A scheme of calibrating the interior and exterior parameters of camera separately is proposed.The measurement uncertainty is obtained by mathematical statistics method.And the accuracy of the calibration for photogrammetry in traffic accident site is analyzed.The results of experiments show that the calibration points and calibration objects should be set up such that they can be easily identified and accurately positioned,while the location of the calibration object has no apparent effect on measurement results.In the experiments,the probabilities for both cases of the photogrammetry error being less than 1.5% in 10m range and the photogrammetry error being less than 2% in 50m range are not less than 99%. |
