摘要
普通数码相机用于目标查找存在许多难题,特别是数据误差来源多,误差大,并且相互影响,一直是国内难以用于生产的关键技术。本文采用摄影测量的基本原理,分析GPS定位、相机畸变、摄影姿态等各种误差来源,并在相机检验、模型定向和坐标计算等数据处理时,制定了消除或减小误差的数据处理流程,提出了低空摄影测量处理软件的设计思路和主要功能,并成功地完成了试验数据处理。
There are many difficulties in using common digital camera to find and check targets,especially the sources of data errors are both more and bigger,and have influence each other,which is the key technique that has been difficult to be used at home right up now.Using basic principle of photographic measurement,the paper analyzed the various sources of errors from GPS positioning,camera distortion to photographic pose,fabricated data processing flow removing or diminishing errors for camera check,model orient...
