Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] In this embodiment, a DMS system distraction detection method comprises the following steps:

[0033] Step 1. Get the vehicle speed signal and power status signal. If the power gear is ON and the vehicle speed is greater than the preset speed, go to step 2, otherwise, repeat step 1;

[0034] Step 2, obtain the driver's image signal, detect the driver's head and head posture based on the driver's image signal, if the driver's head is not detected, then output the unknown signal of distraction;

[0035] If the head is detected and the head posture meets the preset requirements, the driver's line of sight is tracked and detected, and the partition area where the driver's line of sight is located and the duration are output; wherein, the partition area is determined according to the driver's deviation from the normal driving line of sight The angle is divided into safe ...

Abstract

The invention discloses a DMS system attention distraction detection method and system, a vehicle and a storage medium. The method comprises the following steps: 1, obtaining a vehicle speed signal and a power state signal, if a power gear is an ON gear and the vehicle speed is greater than a preset vehicle speed, entering a step 2, otherwise, repeating the step 1; step 2, acquiring a driver image signal, detecting the head and the head posture of the driver based on the driver image signal, If the head of the driver is not detected, outputting an attention distraction unknown signal; if the head is detected and the posture of the head meets a preset requirement, performing tracking detection on the sight line of the driver, and outputting a subarea where the sight line of the driver is located and duration time; and outputting the attention condition of the driver according to the subarea where the sight line of the driver is located and the duration. According to the invention, the dangerous situation of distraction of the driver in the driving process can be accurately judged.

Description

technical field [0001] The invention belongs to the technical field of automobile intelligence, and in particular relates to a DMS system distraction detection method, system, vehicle and storage medium. Background technique [0002] As the current level of intelligence in cars is getting higher and higher, users are paying more and more attention to the safety of driving while enjoying the convenience brought by intelligence. A kind of detection method of driver's fatigue degree based on DMS system disclosed in patent document CN110946595A utilizes DMS system to detect driver's fatigue state, thereby carries out fatigue reminder to driver, but driver is in vehicle driving process, except Fatigue may also cause distraction, which may lead to safety risks during vehicle driving. [0003] Therefore, it is necessary to develop a new DMS system distraction detection method, system, vehicle and storage medium. Contents of the invention [0004] The purpose of the present inve...
