WebLIDAR and radar share a broad array of common and complementary features that can map surroundings as well as measure object velocity. Let’s compare the two technologies in several categories: • Range. LIDAR and radar systems can detect objects at distances ranging from a few meters to more than 200 m. LIDAR has difficulty WebFor the application, we have used the 1200 RPM rotational velocity of the lidar sensor. The acquisition of the intensity and distance Lidar data visually resulted as really responsive inside DewesoftX software. Lidar and GNSS data from DS-IMU2 are synchronized down to each acquired sample, which proves overall synchronization compatibility.
