| 摘 要： | 轻小型组合宽角低空相机由四个非量测的CCD面阵相机组合而成,其内方位元素未知,并且相机畸变差较大.而无人机航空摄影测量作业对CCD相机的光学畸变参数有较高的要求,因为参数的一个像素的误差常常会导致地面几米甚至数十米的误差,因此对组合相机进行高精度检校是无人机航空摄影测量作业的关键步骤.本文采用多片空间后方交会方法在室外...

| Abstract: | The compact and wide-angle composite digital camera is composed by four non-metric CCD cameras,interior orientation elements is unknown,and distortion is great.UAV aerial photography jobs requires high precision CCD camera optical distortion parameters,because the parameters＇ a pixel errors often lead to errors in the ground a few meters or even tens of meters,so high precision calibration of combination camera is the Key step in UAV aerial photography jobs.In this text,applying space resection method calibrate the compact and wide-angle composite digital camera in outdoor three-dimensional control field,using DLT method to calculate the initial value of interior orientation elements,and using coordinate difference of image point to assess the resule of camera calibration,verified the accuracy and reliability of Calibration results. |
