非量测数码相机内方位元素及畸变差检校研究

Non-metric digital camera orientation elements and distortion of the calibration

阐述了数码相机的检校内容和误差来源,对直接线性变换、空间后方交会法进行了研究,并对测量车上的摄像机进行检校,结果表明多片空间后交的检校结果最为稳定,且精度最高,是一种较为可靠的相机检较方法。

It illustrates the content of digital camera calibration and error sources,studies the direct linear transformation and space resection,and makes a calibration for camera on the measurement of the vehicle.The results show that the multi-chip space and submit it to the calibration results of the most stable and most accurate,which is considered to be a more reliable way to check the camera.
