Regulation method for head lamps, device thereof and driver assistance system

Abstract

The embodiment of the invention discloses a regulation method for head lamps, comprising the following steps: acquiring video information of vehicles around a main vehicle; extracting head lamp light source areas of vehicles from video information, and obtaining corresponding area parameters; tracking head lamp light source areas, and obtaining distance between head lamps of vehicles and the main vehicle according to area parameters; calculating with distance to obtain an optimal irradiation parameter of the head lamp of the main vehicle; and regulating position of the head lamp of the main vehicle to position of the irradiation parameter. The proposal provided by the invention can recognize the other vehicles through acquired video information, regulate irradiation height and horizontal deflection angle of the head lamp of the main vehicle, and prevent making drivers of the other vehicles swim by the head lamp, furthermore, the proposal provided by the invention overcomes the defect that operations are complex because drivers frequently and manually switch far and near lights to adapt driving needs in the prior art. Furthermore, a regulation device for head lamps, and a driver assistance system including the same are further disclosed by the embodiment of the invention.

Description

technical field [0001] The invention relates to the technical field of automobile headlights, and more specifically relates to a headlight adjustment method, device and driver assistance system. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the rapid development of the automobile industry, the number of automobiles in our country is increasing. [0003] When driving at night, because the low illuminance of the environment outside the vehicle will cause the driver to obtain less information about the road conditions ahead and around than during the day, most drivers will turn on the headlights of the vehicle for lighting. The high beam of the headlights of the vehicle is directly irradiated, and the driver may cause temporary visual impairment due to the strong light of the headlights, which will affect driving safety. Therefore, various driver assistance devices have appeared on the market, such as radar syst...
