Method for identifying surrounding environment light in vehicle driving

Abstract

The invention discloses a method for identifying surrounding environment light in vehicle driving. The method comprises the specific steps of (1) capturing a dynamic video of an advancing mode of a running vehicle in real time through a vehicle-mounted camera; (2) performing identification judgment on a light region occurring in the video: if the light region is gradually shrunk, ignoring the situation; (3) if the light region is unchanged for a long time or gradually enlarged, performing image black-white binarization on the region, and then detecting the roundness of the light region in a binary image; (4) performing spatial position comparison on vertical projection of the light region; and (5) analyzing a relative position relationship of the light region and the vehicle. According to the method, streetlamps around the running vehicle and vehicle lights of a vehicle running in an opposite direction can be accurately distinguished, and high and low beam lights of the vehicle are switched quickly after it is judged that the vehicle running in the opposite direction appears on the opposite side, so that the possibility of traffic accidents is effectively reduced and the driving safety is ensured.

Description

technical field [0001] The invention relates to a method for recognizing lights in the surrounding environment while a vehicle is running, and belongs to the fields of video collection analysis and image recognition. Background technique [0002] When driving at night, the high beams will be turned on due to poor lighting. However, when two vehicles meet, there are often drivers who forget to change the high beam to low beam according to the traffic regulations. [0003] Using the headlights of vehicles coming in the opposite direction as a basis for whether to turn on the high beam headlights of the own vehicle is an idea to solve the problem of sight when vehicles meet. However, for a moving vehicle, there will be many light sources around the vehicle, including street lamps on both sides of the road, lights of cars driving in the same direction, etc. Most of the existing light sensing technologies are relatively simple, and mainly can only distinguish the With or withou...
