Problems solved by technology

[0003] During the driving process, the driver mainly obtains driving information by looking at the road ahead, but being affected by the surrounding environment, such as operating a mobile phone, watching roadside billboards and other behaviors will cause the driver's sight to deviate from the front gaze area, resulting in the driving process. visually distracted driving
Visual distraction seriously affects the driver's awareness of the current traffic environment and the current road, causing vehicle deviation and other results, increasing the risk of collision

Embodiment Construction

[0043] In order to make the above objects, features and advantages of the present invention clearer, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] figure 1 It is a schematic diagram of front and rear camera installation based on the reverse binocular driving state detection method in the present invention. The front camera is used to collect road video, and the rear camera is used to collect driver video.

[0045] figure 2 It is a structural diagram of a driving state detection device based on reverse dual-purpose in the present invention. The device includes: a video acquisition module, including two cameras front and rear, which simultaneously collect road video and driver's head posture video; image processing The module is used to process the road video, calculate the yaw rate of the vehicle, detect the driver's head posture, and estimate the driver's sight direction; the driver...

Abstract

The invention discloses a reverse dual-purpose driving state detection device and method, which can judge the current driving state of the driver according to the vehicle yaw rate and the driver's head posture. Firstly, lane line detection and recognition are performed according to the Hough algorithm, and the vehicle yaw rate is calculated; at the same time, the multi-point perspective algorithm is used to estimate the driver's head posture; then, the fuzzy judgment rule based on the Gaussian membership function is established, and the The driver's head posture recognizes the driver's driving state and establishes a complete driver's state detection model.

Description

technical field [0001] The invention relates to a detection device and method based on reverse binocular driving state. Background technique [0002] Distracted driving has become one of the important causes of traffic accidents. According to a survey by the National Highway Traffic Safety Administration, 80% of vehicle crashes are caused by driver distraction and inattention. LEE et al. defined distracted driving as the driver turning his attention to activities that are not related to driving, causing the driver's visual and cognitive distraction, resulting in a decline in operating ability. Visual distraction and cognitive distraction refer to drivers taking their eyes off the road and taking their minds off the road, respectively [3] , both will affect the driver's driving behavior. [0003] During the driving process, the driver mainly obtains driving information by looking at the road ahead, but being affected by the surrounding environment, such as operating a mobi...
