Problems solved by technology

However, the existing image-based driver fatigue driving will be affected by the external environment such as complex lighting conditions when acquiring the driver's facial information, and the judgment is only judged by a simple threshold, which will lead to low accuracy.

Embodiment Construction

[0091] In order to have a clearer understanding of the technical features, purposes and effects of this document, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, and the same symbols in each figure represent the same parts. In order to make the drawings concise, the schematic diagrams in the drawings show the relevant parts of the present invention, but do not represent the actual structure of the product. In addition, in order to make the drawings concise and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked.

[0092] As for the control system, functional modules and application programs (APP) are well known to those skilled in the art, they can take any appropriate form, either hardware or software, multiple functional modules discretely set, or It is multiple functional units integrated int...

Abstract

The invention provides an intelligent vehicle-mounted box and a driving fatigue monitoring method. The method comprises the following steps: collecting an image of a driver through a camera on the intelligent vehicle-mounted box, analyzing and processing the image, extracting key features used for representing the fatigue degree from face features, and evaluating the fatigue level of the driver. The key features representing the fatigue degree comprise eye closing frequency and eye blinking frequency, and the key features of the mouth comprise mouth closing frequency. According to the technical scheme provided by the invention, the face of the driver is accurately captured from a plurality of faces of different frames of images, and key features are extracted, so that the misjudgment rate of fatigue monitoring can be reduced while real-time monitoring is ensured.

Description

technical field [0001] The invention relates to safe driving of automobiles, in particular to an intelligent vehicle-mounted box and a driving fatigue monitoring method. Background technique [0002] Traffic accidents are one of the most important factors in accidents, especially on country roads and highways, where fatigue reduces the driver's perception and decision-making ability to control the vehicle. Studies have shown that drivers typically feel fatigued after an hour of driving. In single-vehicle crashes (accidents in which only one vehicle is damaged) or crashes involving heavy vehicles, up to 50 percent of accidents are related to insufficient vigilance of the driver. At this stage, more fatigue detection technologies are applied to automobiles for monitoring, but the applicant's research found that the fatigue detection system is carried out by using the central control host or the vehicle entertainment host mounted on the vehicle. This will undoubtedly consume ...
