Multi-line laser radar barrier detection system and method based on embedded device

The present invention provides a multi-line laser radar barrier detection system based on an embedded device. A three-dimensional point cloud data collection module is a multi-line laser radar which achieves a barrier point cloud data collection function; a data processing sub system based on an embedded device is configured to perform processing and transmission for the collected point cloud data, and all the barrier detection algorithms and detection results are achieved in the embedded device. The present invention further provides a multi-line laser radar barrier detection method. The method comprises the steps of: collecting laser radar data at the front of a vehicle through the point cloud data collection sub system, performing processing of the laser radar data through the data processing sub system, sending three-dimensional point cloud data, barrier information and the relative positions of the vehicle and barriers in a wired or wireless mode to an intelligent vehicle follow-up system to perform obst
