AutoCAD 2018插件在野外像控测量中的应用

Application of AutoCAD 2018 Plug-in in Field Image Control Measurement

随着技术的发展,越来越多的地形测量不再采用传统的全野外数字测图,而是采用摄影测量的方法。野外像控点测量是摄影测量的一个重要步骤,像控点的测量精度直接影响后面空三加密的精度。为了让内业工作人员能够更精确地找到像控点所在的位置,更全面地了解像控点的整体布置,外业人员会根据采集的数据制作像控点结合图,以便内业人员使用,提高内业作业效率和减少错误率。传统制作像控点结合图的方法过于烦琐,人为干预过多,当面对大量像控点数据的时候,会降低工作效率,并有可能发生人为错误。文中针对这一问题,对AutoCAD 2018进行二次开发,编写小插件,提高像控点结合图的制作效率,降低错误率。

With the development of technology,more and more topographic surveys no longer use the traditional all-field digital mapping,but the photogrammetry method.Field image control point measurement is an important step in photogrammetry.The measurement accuracy of the control point directly affects the accuracy of the latter control three encryption.In order to enable the internal staff to more accurately find the location of the control point,and more comprehensive view of the overall arrangement of the control points.The field staff will make a combination of image control points based on the collected data,so that the internal staff can use it to improve the efficiency of the internal operations and reduce the error rate.Traditional methods of making control points combined with graphs are too cumbersome and too much human intervention.When faced with a large amount of image control point data,it will reduce work efficiency and human error may occur.In this article,in response to this problem,the secondary development of AutoCAD 2018,the preparation of small plug-ins,improve the production efficiency of the image point combination map,reduce the error rate.
