非模型化相机标定方法及测角误差研究
Non-Modeled Camera Calibration Method and Error Analysis
摘要
Abstract
Non-modeled camera calibration method is raised from combination of aerial photography optical laboratory method and vertical method. A mapping table from the indexing view angles to CCD coordinates in sub-pixel level is built. The angle measurement process does not depend on imaging model, but by interpolation calculating using standard values in the mapping table. Then the key parameters affecting the accuracy are researched, including the straightness of the one-dimensional target and image processing accuracy, obtaining the system error distribution characteristics and angle measurement uncertainty. The feasibility of this method is verified by experiment results of horizontal angle measuring.关键词
