Abstract

The invention discloses an obstacle recognition method and device for vehicles. The method in one specific embodiment comprises the steps of: acquiring point cloud data of a target area by using a laser radar sensor and acquiring image data of the target area by using an image acquisition device; recognizing obstacle information in the point cloud data by using a preset point cloud recognition model, and marking the recognition result to obtain a first marked result; recognizing obstacle information in the image data by using a preset image recognition model, and marking the recognition result to obtain a second marked result; comparing the first marked result with the second marked result to detect whether the both are same; and responding to the difference of the both, determining an accurate marked result in the first marked result and the second marked result, and outputting the accurate marked result. The method and the device realize quick and accurate recognition of the accurate marked result, do not need artificial marking in the whole course, and thus improve the marking efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of obstacle identification, and in particular to an obstacle identification method and device for vehicles. Background technique [0002] The correct identification of obstacles is of great significance for unmanned vehicles and the automatic driving mode of vehicles. When realizing the automatic identification of obstacles, a laser radar sensor, a millimeter-wave radar sensor or an image acquisition device is usually installed on the vehicle to collect obstacle information around the vehicle to obtain 3D point cloud data or 2D image data. Then, the trained machine learning algorithm is used to identify obstacles in the above-mentioned 3D point cloud data or 2D image data. When training the above-mentioned machine learning algorithm, the three-dimensional point cloud data or two-dimensional image data with marked obstacles are usually used to train the machi...
