1 PRODUCT OVERVIEW YDLIDAR X4 is a 360° 2D LiDAR(hereinafter referred to as X4) developed by YDLIDAR team. Based on the principle of Triangulation, it is equipped with related optics, electricity, and algorithm design to achieve high-frequency and high-precision distance measurement. The mechanical structure rotates 360 ° to continuously output the angle information as well as the point cloud data of the scanning environment while ranging. 1.
FIG 2 YDLIDAR X4 MECHANICAL DIMENSIONS 2 SPECIFICATIONS 2.1 Product Parameter CHART 1 YDLIDAR X4 PRODUCT PARAMETER Item Min Typical Max Unit Ranging frequency / 5000 / Hz Motor frequency 6 / 12 Hz Ranging distance 0.12 / >10 m Fileld of view / 0-360 / ° / Systematic Error / 2 / cm Range≤1m Statistical Error / 3.5% / / 1m
Note1: The range and relative accuracy in the above table are factory values. Note2: In the above table, the relative error value represents the accuracy of the lidar measurement, Statistical Error = (Ranging distance - actual distance)/ actual distance * 100%. LiDAR is a precision equipment, which needs to be protected during use. In the use scenarios of high temperature, high and low temperature or strong vibration, the parameter index of relative error will be relatively larger. 2.
