Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0028] Such as figure 1 As shown, a driver's load detection device includes:

[0029] The collection unit is used to collect images including traffic environment information in front of the vehicle and the driver's heart rate variability. The traffic environment information includes lane lines, road signs and signal lights, and the collection unit includes installation in the middle of the front windshield Camera and heart rate sensor set on the steering wheel;

[0030] The image processing unit extracts and recognizes environmental information by processing the image information of the visual acquisition unit, including: ro...

Abstract

The invention discloses a vehicle-mounted device for detecting a driver workload based on image identification. The device comprises a collection unit, an image processing unit, a road alignment load level calculation unit, a visual load level calculation unit, a display unit and a storage unit, wherein the display unit is used for receiving data of the road alignment load level calculation unit and the visual load level calculation unit, displaying a comprehensive driving load of a road environment in real time after quantitative fusion, and displaying a running state of a system. According to the vehicle-mounted device for detecting the driver workload based on the image identification, the visual load of a driver and the mental load caused by road alignment are fused, and the comprehensive driving load of the driver is displayed and can be analyzed by a administrative department and a design department.

Description

Technical field [0001] The present invention relates to assisted driving technology, in particular to a vehicle-mounted device for driver load detection based on image recognition. Background technique [0002] Currently, during driving, more than 60% of the information is obtained through vision. When the visual information increases, the visual workload will increase, and the corresponding visual load will also increase. The higher visual load will cause the driver's information processing to be delayed, increase operation errors, and affect traffic safety. The road environment that has a greater impact on the visual load of the driver mainly includes road horizontal and vertical lines and traffic sign information. Visual load is a component of driving workload. Someone has used changes in the number of blinks, the number of gazes, or pupil area to evaluate the intensity of the driving workload. It is believed that when the visual distance pressure increases, the driver will t...
