System and method for pre-warning of fatigue driving

Abstract

The invention relates to a system and a method for pre-warning of fatigue driving. The system comprises a microprocessor, a memorizer, a memory, a display unit, a GPS (global position system) navigation and input / output unit, an image collection unit, a vehicle condition detection unit and an alarming unit, wherein the image collection unit uninterruptedly collects image information of facial expression of a driver in real time; the vehicle condition detection unit detects vehicle driving parameters; and the microprocessor transfers an image feature template stored in the memorizer in real time, judges whether the driver is in a fatigue state or not by the image recognition technology, and comprehensively judges whether the driver is in the fatigue state or not through normal formulas of probability statistics by the vehicle driving state obtained by the vehicle condition detection unit, and once the judgement result is YES, the alarming unit is started to transmit an alarming signal. In addition, the driver can determine whether the navigation function is used or not according to the requirement by the system. The system and method have the characteristics that the image recognition algorithm is advanced, the fatigue state judgment is accurate, the influence of ambient light is small, a plurality of navigation software can be compatible, the use is convenient, and the like.

Description

technical field [0001] The invention relates to the field of active and safe driving of vehicles, in particular to a fatigue driving early warning system that judges whether the driver is in a fatigue state by combining image technology and vehicle condition driving statistical data, and issues an early warning according to the judgment information to prevent traffic accidents caused by fatigue driving and methods. Background technique [0002] In the process of vehicle driving, especially during long-distance driving, the driver is prone to fatigue due to poor physical condition or driving for a long time. Changes, such as: decreased vision, resulting in distraction, gradually narrowing of vision; decreased thinking ability, slow response, slow judgment, stiff movements, rhythm disorders; decreased self-control ability, resulting in easy agitation, impatience or fast driving, etc. If you continue to drive at this time, it is considered fatigue driving. [0003] The functi...
