Abstract

The invention relates to a barrier detection method and device and belongs to the field of intelligent traffic. The method comprises the following steps: obtaining radar parameters of at least one barrier around a vehicle through a millimeter wave radar; obtaining vision parameters of the at least one barrier through a vision sensor; and fusing the radar parameters and the vision parameters of each barrier and serving the fused parameters as target parameters. According to the method, by fusing the radar parameters obtained through the millimeter wave radar and the vision parameters obtained through the vision sensor and serving the fused parameters as the target parameters of the barrier, the accuracy of the azimuth detected by the vision sensor is high, the problem that accuracy of the detected azimuth of the barrier is low in the correlated technology is solved, and the effect of high accuracy of the detected parameters of the barrier is achieved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an obstacle detection method and device. Background technique [0002] At present, more and more vehicles include the function of obstacle detection, which can detect obstacles around the vehicle and inform the driver, providing accurate basis for the driver's driving decision. [0003] There is a method for detecting obstacles in the related art, which uses millimeter-wave radar to detect obstacles around the vehicle, and parameters of the obstacles detected (such as the distance between the obstacle and the vehicle, the orientation of the obstacle, and the height and width, etc.), so that the driver can adjust driving decisions according to the displayed obstacle parameters. [0004] In the process of realizing the present invention, the inventor found that the above-mentioned method has at least the following defects: the above-mentioned method uses the millimeter-wa...
