YDLIDAR X4 PRO is a 360 degrees two-dimensional rangefinder (hereinafter referred to as X4PRO) developed by EAI team. Based on the principle of triangulation, it is equipped with related optics, electricity, and algorithm design to achieve high-frequency and high- accuracy distance measurement. The mechanical structure rotates 360 degrees to continuously output the angle information as well as the point cloud data of the scanning environment while ranging.
The shipment delivery was fast and efficient. They even called me before shipping the order to let me know when the order will be dispatched and estimated time of arrival. Very happy with their service.
