Intelligent technology for monitoring water levels based on shore-based LiDAR
Traditional methods consumed a lot of manpower and material resources and it was difficult to realize real-time monitoring around the clock in harsh environments such as night and rainy days.An intelligent technology for sensing water levels based on shore-based LiDAR was developed.Shore-based LiDAR data acquisition platform was established and areas of interest were selected taking relative horizontal angle and vertical azimuth as parameters.The algorithm was developed to analyze the UDP protocolto parse LiDAR data on its own and effective point cloud information on the water surface was extracted.The water surface equations were constructed by fitting discrete point clouds to calculate and correct water level.The algorithm was verified in a real scenario.The data showed that the intelligent technology for sensing water levels based on LiDAR could effectively monitor the water level.The mean absolute error was 0.057 m,the root mean square error was 0.073 5 m,and the mean percentage error was 7.588％.
