Abstract

The invention relates to a target detection method and device. The method comprises: first scanning data sent by a radar and image data sent by a digital image device are received; because primary positioning information of an obstacle target can be provided by the first scanning data, image information corresponding to all obstacle targets are searched in the image data based on the first scanning data, so that unnecessary image searching is reduced and the image processing speed is increased and thus the obstacle types can be identified rapidly; and according to the obstacle types, when existence of an obstacle target needing to be avoided is determined, the radar is controlled to carry out second type scanning and tracking on the obstacle target needing to be avoided and, that is, precise scanning and tracking are carried out, so that precise tracking and detection on the obstacle target can be realized during the follow-up operation process by utilizing the precise positioning advantage of the radar. Therefore, with the target detection method and device, the detection precision and efficiency on the obstacle target can be improved, so that the driving potential safety hazard is reduced.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a target detection method and device. Background technique [0002] With the development and innovation of science and technology, unmanned driving technology is becoming more and more mature. Among them, driverless cars are smart cars that sense the road environment through the on-board sensor system, automatically plan the driving route and control the vehicle to reach the predetermined target. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained from the perception, so that the vehicle can drive safely and reliably on the road. [0003] However, due to the complexity and variability of road traffic, obstacles such as pedestrians and vehicles need to be detected accurately in real time in order to avoid them reaso...
