YDLIDAR provides Point Cloud Viewer, a point cloud data visualization software for X4 real-time
scanning. The user can intuitively observe the X4 scan effect picture using this software. YDLIDAR
provides X4 real-time point cloud data and real-time scanning frequency, and X4 version
information can be read at the same time. And can save the scan data offline to an external file for

Before using YDLIDAR, make sure that the X4 USB adapter board serial port driver is installed
