摘要
通过分析航空摄影中数码相机的误差来源及规律,提出了利用专用检校场检校数码相机的数学模型、理论方法和实用检校步骤,并在分析实际检测数据的基础上,完善了控制点的获取效率进而改进了控制点的布设方案,最后通过实验论证了此方法的高精度性、可靠性与可行性。
This paper presented the mathematical model,theoretical approaches and practical calibration steps of calibrating digital cameras using the special calibration field,basing on analyzing the error source and rules of aerial photography digital cameras.The efficiency of obtaining control points and the scheme of designing control points were improved.At last,the high precision,reliability and feasibility of the method were demonstrated by the experiment.
