|
摘要
普通相机标定的三维控制架降低了控制场的建设成本,使用户自主进行相机标定成为可能。针对如何快速准确进行三维控制架测量,获得高精度控制点坐标问题,该文分别采用两测站空间前方交会法和单测站空间极坐标法对三维控制架进行测量,分析对比两种方法的测量精度,并总结出提高测量精度的方法。实验表明,两测站空间前方交会法测量精度高,测量方法简便易行,精度稳定可靠。
It reduces the construction cost of the control field when using three dimensional control frame for the conventional camera calibration,and it is possible for users to make camera calibration.So,How to measure the 3D control frame quickly and accurately rely on getting the high precision control point coordinates which is an important problem to be solved.In this paper,the three-dimensional control stand was measured by the two station space forward intersection method and the single station space polar coordinate method.Comparision between the measurement accuracy of two methods was carried on,and the methods to improve the precision of measurement was analized.The experiment showed that the two station space forward intersection measurement had higher precision,more reliable precision and easy to carriy on.
