Problems solved by technology
However, when the car is running at high speed, it is difficult to accurately interpret the image information, and it takes a certain amount of time to interpret and distract the driver's attention. However, safety accidents often occur in an instant. This image-based safety reminder method does not It cannot effectively solve the safety problem. In addition, various factors that affect the safety of the car are often integrated, and it is difficult for people to make judgments in a short time.

specific Embodiment approach
[0016] During high-speed driving, the safety impact mainly comes from PSTOs. According to the geometric size and relative motion of PSTOs, it is necessary to judge the comprehensive influence degree of PSTOs on automobile safety, and give a quantitative evaluation method of safety risk. Based on this, judge the current safety status and development trend of the car, and then take effective control measures to prevent problems before they happen. The specific implementation is as follows:
[0017] Step 1: Identify the geometric information and motion information of the surrounding objects of the car through relevant sensors
[0018] The specific implementation steps are as follows:
[0019] 1. Arrange related sensors on the car
[0020] These sensors shall meet the following technical requirements:
[0021] (1) It can be applied to high-speed vehicles, and the maximum speed limit v can be set according to the measurement constraints of the sensor T (v T >0);
[0022] (2)...

The invention relates to an automobile visual safety situation awareness method based on a surrounding object collision risk. The method specifically comprises the following four steps of 1, acquiring geometric information and motion information of objects around an automobile through a sensor; 2, processing geometric information and motion information of objects around the automobile, and abstracting the geometric information and the motion information into simple geometry and relative motion information; 3, judging the safety risk of each object around the automobile according to the collision possibility of the object in the automobile and the damage degree of the collision; and 4, integrating the safety risk of each object, and judging the safety risk level of the automobile.
Description
[0001] Technical field [0002] The invention relates to manned or unmanned vehicles, especially in the driving process of manned or unmanned vehicles, quantitatively evaluates the comprehensive impact of surrounding objects on the safety of the vehicle, and the information can be fed back to the driver or the automatic driving system , and then operate the car correctly to avoid safety accidents to the greatest extent. The invention belongs to the technical field of automobile safety. Background technique [0003] High-speed cars, surrounding cars, people, stones, guardrails and other objects all pose a safety threat to the car. Correctly identifying and accurately evaluating the impact of these objects on car safety is of great importance for the safe driving of cars and the safety of members. significance. In recent years, with the development of automotive electronics technology, the image information of the surrounding scenes of the car can be transmitted to the driver ...
