Abstract

The present invention provides a vehicle recognition method, device and terminal, which relate to the technical field of assisted driving. The width falls within the preset width range and is less than the preset width threshold, and the second grayscale image of the area where the obstacle frame is located is intercepted from the first grayscale image taken; Horizontal line segments, and determine the axis of symmetry based on the horizontal line segments; if the ratio of the number of horizontal line segments that are left-right symmetrical based on the axis of symmetry to the number of all horizontal line segments is greater than a preset ratio threshold, determine the obstacle in the obstacle frame Things are vehicles. The invention can effectively improve the accuracy of vehicle identification.

Description

technical field [0001] The present invention relates to the technical field of driving assistance, in particular to a vehicle identification method, device and terminal. Background technique [0002] Vehicle recognition is the basis of automotive assisted driving applications. Fast and accurate vehicle recognition can effectively reduce the occurrence of traffic accidents. [0003] At present, vehicle recognition technology mainly detects obstacles based on the disparity map obtained by binocular vision technology. Through detection, the size of the obstacle in three-dimensional space and the distance from the obstacle to the camera can be obtained. The actual height, actual width, and the ratio of width to height determine whether the obstacle is a vehicle. However, when multiple people walk side by side, or other obstacles similar to the width and height of the vehicle appear, it will be misidentified as a vehicle. Therefore, the accuracy of recognition is not high. Con...
