VeloView is an open-source application designed for real-time visualization and processing of 3D LiDAR data captured from Velodyne's HDL sensors, including models such as HDL-64E, HDL-32E, VLP-32, VLP-16, Puck, Puck LITE, Puck Hi-Res, Ultra Alpha, Alpha Prime, Velarray, Velabit, and Veladome. It enables users to visualize live data streams or playback pre-recorded data stored in .pcap files, with the capability to record live streams for subsequent analysis. The software provides tools to display, select, and measure information from captured points, supporting custom color maps based on variables like intensity-of-return, time, distance, azimuth, dual return type, and laser ID. Users can export data as XYZ in CSV format or capture screenshots of the point cloud display. Recent updates have introduced features such as support for Velarray sensors, simultaneous operation of multiple sensors, independent live data transformation for each sensor.
