Aerial Photograph Location Technology

讨论航空摄影图像的系统几何校正方法,针对机载摄像平台对地观测系统,建立从相机坐标系到地球坐标系的一系列空间坐标系统。根据各个坐标系相互转换关系,建立系统几何校正模型,对图像进行系统几何校正计算,完成图像定位。实验结果表明在有激光测距数据参与情况下,提高原模型的校正计算精度,能够有效完成航拍视频图像的校正和定位计算。

The paper introduces a method for system geometric correction of aerial photograph. For onboard camera of Earth observation system, a series of space coordinate systems from camera coordinate system to Earth coordinate system are proposed, and based on the coordinate system transformation relationship, a system geometric correction model is established for image system geometric correction calculation and location. Experiment results show that this model can improve the correction calculation precision, and accomplish the correction and location calculation of aerial photograph.
