视电阻率等值线图水体区域自动识别系统

Automatic identification systems of water regions of apparent resistivity contour maps

为了实现对视电阻率等值线图中的疑似水体区域进行识别,开发了一种基于不规则三角网(TIN)等值线填充与Open CV轮廓提取对各个水体区域进行涂色与识别的系统,改进了等值线填色过程,并根据提取的水体区域轮廓拓扑关系树,计算各个区域面积,给出区域在图像中的具体位置。通过对自动识别结果与人工识别结果的对比,验证系统的实用性,说明系统能够快速准确地识别出视电阻率等值线图的水体区域。

In order to identify the suspected water regions of apparent resistivity contour maps,develop a system of filling contour maps based on triangulated irregular network（ TIN） and identification of each water regions based on open source computer Vision（ Open CV） outlines extraction,improve contour coloring process,and according to the extracted water area contour topology tree,calculate area of each region,give specific location of area in image. By comparing results of automatic identification with manual identification results,verify practicality of the system,it indicates the system can quickly and accurately identify the water body regions of apparent resistivity contour maps.
