Abstract

The invention belongs to the technical field of intelligent driving, relates to an early warning method, system and device for identifying the driving behaviors and dangerous driving behaviors of thedriver, and aims to solve the problem that a driver driving behavior identification method is low in recognition accuracy and fails to share identified dangerous driving behavior information. The method comprises the steps of: acquiring the driving behavior depth image of a driver; and obtaining the driving behavior state of the driver through a driving behavior identification model; and carryingout danger grade judgment on the identified driving behavior state of the driver based on a preset driver behavior state grading rule, and carrying out early warning prompting according to a preset danger grade early warning mode. According to the method, a driving behavior identification model is trained through transfer learning, so that the accuracy of driving behavior identification is improved; and identified dangerous driving behaviors are broadcasted in time, so that information sharing is achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent driving, and in particular relates to a method, system and device for identifying driver's driving behavior and early warning of dangerous driving behavior. Background technique [0002] As the number of cars increases, traffic accidents occur more frequently. Irregular driving behavior has serious potential safety hazards, which is also the main reason for more than 80% of traffic accidents. Therefore, monitoring the driver's driving behavior has extremely important application value. With the development of image processing and computer vision technology, the driver monitoring system based on computer vision has become the mainstream development direction of driver behavior recognition. [0003] At present, the existing vision-based driver behavior recognition technology has the defect that the recognition result is not accurate enough. The main reasons are as follows: [0004] (1) The tr...
