Abstract

The embodiment of the invention discloses a collision identification method and device, equipment and a storage medium. The method comprises the following steps that if the motion state of a moving object is detected to abruptly change according to speed information of the moving object, the abrupt changing speed, the abrupt changing acceleration and the abrupt changing time are determined, whether the moving object collides or not is determined according to the abrupt changing speed, the abrupt changing acceleration, a collision speed threshold and a collision acceleration threshold, if the collision occurs, the collision duration span is determined according to speed change information after the sudden change time, and the collision degree of the moving object is determined according tothe collision duration span. According to the method of the embodiment, by acquiring the abrupt changing speed of the moving object, whether the moving object collides or not is determined, the collision degree of the moving object is determined according to the speed change information after collision, hardware equipment for acquiring acceleration information is reduced, the requirement on hardware is reduced, accurate judgment on the collision degree is realized at the same time, and the processing efficiency of a collision accident is improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method, device, equipment and storage medium for collision recognition. Background technique [0002] With the gradual increase of vehicles, people pay more attention to the safety of vehicle operation, and users cannot remotely monitor the safety situation of vehicles while driving. Therefore, when vehicles collide, they cannot be processed in time according to the collision situation. [0003] At present, car collision alarms are generally processed by specialized hardware devices, and the hardware devices obtain the movement speed and acceleration respectively. When the acceleration sensor determines that the acceleration exceeds the preset threshold, it is considered that a collision has occurred. [0004] However, the existing technology is limited by hardware equipment, the cost of hardware development and upgrading is high, and the judgment of the degree o...
