Research on River-lake Demarcation Technology Fusing Radar Point Cloud andOrthophoto
In the demarcation of rivers, lakes and water conservancy projects, whenthe airborne lidar point cloud data is used alone to automatically filter andclassify, low vegetation points are easily misclassified and misjudged as Lifestyle groundpoints,affected by the dense distribution of vegetation in the measured area, thusresulting in the failture of
