Problems solved by technology
[0003] At present, the active safety of automobiles mostly focuses on the environment of people and vehicles in the lane, and pays less attention to the state of vehicles in the side lane. In the current complex traffic conditions, there are often side lane changes and lanes and crossing two lanes. If the situation arises and brings potential safety hazards, if the lane-changing awareness of vehicles in the side lane can be identified in advance, the driver can respond in advance to achieve safe driving
[0004] The traditional vehicle intention recognition system mainly judges the lane-changing intention of the vehicle in the side lane by identifying whether the turn signal is turned on, but it cannot recognize the lane-changing situation without turning on the turn signal. In this case, it is impossible to know the change of the vehicle in the side lane Road information brings safety hazards to safe driving

The embodiment of the invention provides a method and a system for identifying the lane changing intention of a side lane vehicle. The method comprises the following steps: firstly, determining a lateral image area of a side lane in a real-time acquired image of the side lane; locking an analysis target in a small range; then, determining the areas of the front wheel and the rear wheel in the lateral image area. The analysis complexity can be reduced;, by efficiently obtaining the deflection angle of the vehicle relative to the side lane, the lane changing consciousness of the vehicle in the side lane can be identified in advance in a complex traffic road condition through the deflection angle, so that a driver makes a response in advance, potential safety hazards caused by lane changing of the vehicle in the side lane without turning on a steering lamp are avoided, and the driving safety of the vehicle is improved.
Description
technical field [0001] The invention relates to the field of automobile active safety, in particular to a method and system for identifying lane-changing intentions of vehicles in a side lane. Background technique [0002] With the continuous increase of car ownership, the awareness of safe driving has also been continuously improved. Car active safety is an important aspect of safe driving, which refers to the performance of the car itself to prevent or reduce road traffic accidents. [0003] At present, the active safety of automobiles mostly focuses on the environment of people and vehicles in the lane, and pays less attention to the state of vehicles in the side lane. In the current complex traffic conditions, there are often side lane changes and lanes and crossing two lanes. If the situation arises, it will bring potential safety hazards. If the lane-changing awareness of vehicles in the side lane can be identified in advance, the driver can respond in advance to achie...
