Lake detection algorithm in point clouds of the lidar image based on three-dimensional convolutional neural network

Abstract

An algorithm for detecting lakes in a point cloud of a lidar image based on a three-dimensional convolutional neural network is proposed. The contours of the lakes were extracted from the point clouds of the lidar image and their geometric characteristics were determined using the chain code algorithm. The accuracy of the proposed algorithm for identifying lakes from clouds of laser scanning points was 96.34%. The proposed algorithm can calculate and analyze information about the shape of lakes.
