Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0039] The vehicle behavior early warning method provided in this application can be applied in the following application environments. The first scene is defined as the actual driving scene of the vehicle, and the second scene is the pre-trained scene of the vehicle behavior early warning model. After training the early warning model in the second scene, the vehicle drives in the first scene, and obtains the early warning type of the first image sequence in the first scene through the early warning model, and the user makes feedback information according to whether the ear...

Abstract

The present application relates to a vehicle behavior early warning method, device, computer equipment and storage medium. The method includes: acquiring a first image sequence of a vehicle driving in a first scene, inputting the first image sequence into a pre-trained early warning model to obtain a risk assessment value; obtaining a vehicle early warning type according to the risk assessment value; When the warning type does not match the feedback information, the label value corresponding to the first image sequence is generated according to the risk assessment value; the early warning model is corrected according to the first image sequence and label value, and the corrected model is used. The early warning model provides early warning for vehicle behavior. This method can solve the problems of poor scene mobility, large error and low use efficiency of the vehicle behavior early warning model.

Description

technical field [0001] The present application relates to the technical field of vehicle safety driving, in particular to a vehicle behavior early warning method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of social economy, automobiles have entered our daily life in an all-round way, and the safety hazards brought by automobiles have also increased rapidly. Since the artificial active safety control is affected by various self- and external uncontrollable interference factors, the safety risk is high with low precision. With the improvement of people's material base and knowledge and cultural level, people pay more attention to and pursue the safety and comfort of driving. Therefore, in order to effectively reduce or eliminate driving safety accidents caused by human factors and complex traffic factors, vehicles Driving danger warning technology becomes very necessary. [0003] Existing vehicle behavior early wa...
