摘要
主要通过理论分析和实验验证,论述了非量测型相机检校在无人机摄影测量技术中的关键作用。相机检校的精度能直接影响空三加密的质量,从而影响最终数字产品的质量。因而,在实际生产中,要重视无人机所搭载的非量测型相机的检校。
Through theoretical analysis and experimental verification, this paper narrates the key role of non-metric camera calibration in UAV photogrammetric.The accuracy of camera calibration can directly affect the quality of the aerial triangulation, thus affecting the quality of the final digital product.Therefore, in production, we should pay attention to the camera calibration.
