Embodiment Construction

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0043] In the existing method of detecting continuous obstacles through the U disparity map, a straight line is simply fitted by a straight line fitting algorithm in the U disparity map, and the straight line is used to represent the position of the continuous obstacle in the U disparity map. Location. The disadvantage of this is that the straight line fitting algorithm simply counts the points existing in the U disparity map without any prior information to detect the correctness of the fitting. by Figure 7 Take the U disparity map ...

Abstract

The present invention discloses a continuous obstacles detection method and apparatus, and a terminal, and relates to the technical field of assisted driving. The method is characterized in that: by taking the vanishing point of the road as a reference, in a U disparity map, different regions are divided from specific perspectives to form different sub-U disparity map regions, and the parallax points that do not belong to the same category fall into different sub-U disparity map regions, so that the continuous obstacles and the parallax points of the vehicle are classified to the different sub-U disparity map regions; and then, in different sub-U disparity map regions, straight line fitting is performed separately, the distinction between the continuous obstacles and the parallax points ofthe vehicle is implemented, and through separate straight line fitting, the problem of misdetection due to that the parallax points that do not belong to the same category are fitted together is avoided, and the accuracy of continuous obstacles detection is improved. According to the method disclosed by the present invention, for the vehicle detection, a side vehicle collision warning can be provided for the driver, so that the probability of a traffic accident is reduced.

Description

technical field [0001] The present invention relates to the technical field of driving assistance, in particular to a continuous obstacle detection method, device and terminal. Background technique [0002] Continuous road obstacles refer to continuous roadside fences, bushes, billboards, etc. In the continuous obstacle detection method based on binocular stereo vision, the detection algorithm is difficult to distinguish between real continuous obstacles and non-continuous obstacles (such as vehicles). Therefore, the effective parallax points of continuous obstacles in the parallax image will be reduced; secondly, vehicles driving normally on both sides will occlude continuous obstacles, and it is often difficult to distinguish continuous obstacles by using general detection algorithms. Obstacles and non-continuous obstacles (such as vehicles). [0003] In the prior art, the continuous obstacle detection method based on binocular stereo vision is mainly by extracting a cer...
