一种结合已有DOM和DEM的高精度自动刺像控点方法
|
摘要
针对基础地理数据更新需求,为了免去外业布设控制点,减少内业刺点工作量,提高控制点精度、密度,提出了一种基于已有DOM和DEM数据,利用IPS软件和辅助软件,实现高精度自动刺像控点的方法。将已有DOM根据具体匹配需求裁切,裁切后的DOM和像片同时加载到IPS中进行同名像点匹配,根据DOM的地理参考、匹配点像平面坐标、TFW头文件及DEM共同解算出匹配点的物方坐标。通过平差探测和目视检查剔除错误点,改变匹配点属性为控制点,即完成了控制点刺入工作。之后可在IPS中继续完成空三处理、地理信息产品制作等,也可导出、转换为其他软件的文件格式,供后续处理使用。
Referring to the basic geographic data updating requirements,in order to eliminate the field work in laying control points,reduce the office workload in pricking points and improve the precision and density of control points,this paper presents a method based on existing DOM and DEM data by using IPS and auxiliary software to realize high-precision automatic pricking control points. Clipping the existing DOM according to specific matching requirements,loading the DOM and the images into IPS at the same time to match tie points,calculating the object space coordinates of the matched points according to DOM graphic reference, tie points image coordinates,TFW file and DEM. Removing the error points through adjustment detection and visual inspection,then changing the attribute of the matched points to complete the work of pricking control points. After that,we can continue processing in IPS to complete the steps of aerial triangulation,geographic information product production etc.,or export and convert them into other software format for subsequent processing.
