Abstract

The invention discloses a road deceleration line identification method and device and a vehicle. The method comprises the following steps that a present road image in front of the vehicle is collected, and processed to obtain a binary image and an edge image; according to the binary image and the edge image, target characteristic points are extracted to obtain characteristic points of a road deceleration line; point-line dual transformation is carried out on the characteristic points of the road deceleration line on the basis of a Hough transformation principle, and horizontal line informationin the front road image is obtained; and the road deceleration line is identified according to the horizontal line information. The road deceleration line identification method can be used to identify the road deceleration line in front of the vehicle, and the active safety of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a road deceleration line identification method, a road deceleration line identification device and a vehicle. Background technique [0002] With the popularization of automobiles, the use of sensors to improve the ability to identify road objects and provide drivers with more safety warnings and assistance, thereby improving the active safety of vehicles, has become an important direction for the development of intelligent transportation systems. [0003] At present, the main recognition objects in multi-way object recognition include: vehicles, lane lines, traffic signs, etc., but there is a lack of recognition of road deceleration lines and deceleration warnings. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0005] Therefore, the first object of the pre...
