Title: OBSTACLE DETECTION METHOD AND DEVICE
Abstract:
An obstacle detection method and system (100), which are used for avoiding a relatively large data processing capacity and also improving obstacle recognition accuracy. The method comprises: an obstacle information processing device (110) receiving description information about n obstacles collected by an obstacle detection data collector (120) for a target vehicle, updating an obstacle information list according to the description information about the n obstacles, and obtaining the updated obstacle information list; the obstacle information processing device (110) obtaining target area information and non-target area information according to the updated obstacle information list, and sending the target area information and the non-target area information to a laser radar data collector (130); the obstacle information processing device (110) receiving a set of sampling points collected by the laser radar data collector (130); and finally, the obstacle information processing device (110) obtaining an obstacle detection result according to the set of sampling points and the updated obstacle information list. Therefore, a relatively large data processing capacity is avoided and the obstacle recognition accuracy is also ensured.
