LiDAR Resolution Analysis

The resolution of LiDAR is determined by global resolution, point frequency and angular resolution. Global resolution reflects clarity, point frequency indicates the number of laser points emitted per second, and angular resolution refers to the angle between adjacent beams. Hesai AT128 has a global resolution of 1200x128, a point frequency of 1.536 million points/second, and a refresh rate of 10Hz; AT512 has a resolution of 2400x512 and a point frequency of 12.3 million points/second.
