摘要
研究了一种无人机摄影测量中非量测相机快速检校技术，该技术不需要布置严格的三维控制场，只是需要相机在一定方向、角度拍摄一组模板像片，并依据构像方程和畸变模型，利用旋转矩阵约束条件即可推导出相机内参求解公式。实验结果表明，内参数稳定，检校结果可靠，为控制条件不充足情况下的几何标定和非量测相机快速检校提供一种解决方案。
A fast calibration technology for non - metric camera in UAV photogrammetry is studied in this paper. Without a strict three - dimensional control field, it only needs a group of planar templates taken from different directions and different an- gles. The templates can be rotated and the camera can be adjusted as well. Then the camera calibration parameters are calculated by using the rotation matrix constraints based on the imaging equation and distortion model. Experiment results show that the parameters are stable and the calibration result is reliable, which provides a solution for geometric correction and non - metric camera fast calibration under the condition of lacking 3D control points.
