实现摄影测量中POS数据，直接解算影像外参数，使用python编写的photoscan脚本来实现。但注意的是：这是通用转换方法，若POS硬件不同，需要修改部分参数-Achieve photogrammetry POS data, foreign direct solver image parameters using python write photoscan scr ipt. But note: This is a common method of conversion, if different POS hardware, you need to modify some parameters
