Problems solved by technology

There are many deficiencies in the method of obtaining the walking path of pedestrians only based on the previous few frames of images of pedestrians combined with the method of function fitting, and the walking direction of pedestrians is difficult to fit through functions, and the dangerous area is determined by dividing the dangerous area in the direction of vehicle speed. The method does not consider the lateral distance between pedestrians and vehicles, and there will be many false positives in

Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 As shown, the vehicle-pedestrian collision risk identification and decision-making method described in the present invention is divided into the following steps:

[0062] 1) Information collection: collect information for identifying collision risks; the information includes vehicle speed information, acceleration information, location information, and the number, location, and road information of pedestrians;

[0063] Among them, information collection uses vehicle-mounted collection terminals and roadside collection terminals;

[0064] The vehicle-mounted acquisition terminal uses cameras, infrar...

Abstract

The invention discloses a method and a system for avoiding the vehicle and pedestrian collision in road-vehicle coordination environment. The method comprises the following steps including (1) information collection: information used for identifying collision risk is collected; (2) driving state discrimination: the current driving state of a vehicle is discriminated; (3) collision risk identification: whether the collision risk exists or not is identified according to the collected collision risk information and the current driving state of the vehicle; (4) driving state discrimination: if the collision risk exists, whether the current driving state of a driver is normal or not is discriminated; (5) collision avoiding: a targeted avoiding method is adopted according to the driving state of the driver for implementing the collision avoidance. The method provided by the invention has the advantage that the in-time adaptation to the actual driving condition can be realized for realizing effective avoidance on different dangerous conditions.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle-pedestrian collision avoidance method and system in a vehicle-road collaborative environment. Background technique [0002] A variety of pedestrian collision avoidance devices have been developed at home and abroad for vehicle-pedestrian collision avoidance. At the same time, some researches have been done on vehicle-pedestrian collision avoidance methods. Domestically, a pedestrian anti-collision warning method based on recognition of driver's braking and acceleration intentions has been disclosed (China Patent No.: 201310640000.3). This invention uses infrared technology to detect pedestrians, and by analyzing the maneuvers that the driver may take when encountering pedestrians in front of the car Behavior and strategy, make corresponding early warnings based on driving behavior and intentions, and at the same time give early warnings for wrong driv...
