Embodiment Construction
[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.
[0055] Before explaining in detail the method for determining the collision angle of a car provided by the embodiment of the present application, the application scenario provided by the embodiment of the present application is firstly introduced
[0056] At present, in order to ensure the safety of drivers and passengers, in the process of automobile research and development, it is more important to conduct collision tests on automobiles. Among them, after a collision occurs, the change of the collision angle between the automobile and the collision object is an important indicator to measure the quality of the automobile. At present, the change of the collision angle between the car and the collision object requires m...

The embodiment of the application discloses a method, a device and a computer storage medium for determining a collision angle of an automobile, which belong to the technical field of automobile testing. The method includes: before the test car collides with the collision object, the first included angle and the second included angle are obtained through the camera, the first included angle is the included angle between the test car and the reference line set in the current environment , the second included angle is the angle between the collision object and the reference line; after the test car collides with the collision object, the third and fourth included angles are obtained, and the third included angle is the angle between the test car and the reference line The fourth included angle is the included angle between the collision object and the reference line; according to the first included angle, the second included angle, the third included angle and the fourth included angle, determine the distance between the test vehicle and the collision object Collision angle. In the embodiment of the present application, the included angle of the collision is determined by testing the angle changes between the car and the collision object and the reference line before and after the collision, which improves the accuracy and reliability of determining the collision angle.
Description
technical field [0001] The embodiments of the present application relate to the technical field of automobile testing, and in particular to a method, device and computer storage medium for determining a collision angle of an automobile. Background technique [0002] With the development of technology in the field of automobile safety, collision testing has become an important part of vehicle quality inspection. In order to ensure the accuracy of the test and the reliability of automobile research and development during the automobile collision test, when the automobile collides with the collision object, it can pass the automobile The change in the angle of collision with the collider determines the mass of the car. [0003] At present, when determining the collision angle, the angle, direction and speed of two or more measured objects are usually manually adjusted to cause them to collide, and then the collision results are manually analyzed to obtain the collision angle. ...
