YDLIDAR provides Point Cloud Viewer, a point cloud data visualization software for G4 real-time

scanning. Users can intuitively observe the G4 scanning effect chart. GDL real-time point cloud data

Before using the YDLIDAR software, make sure that the G4 USB adapter board serial port driver is

installed successfully, and interconnect the G4 with the USB port of the PC. Run the evaluation

software: PointCloudViewer.exe, select the corresponding serial port number and model number.
