Embodiment 1

[0033] figure 1 It is a structural schematic diagram of the vehicle fatigue driving warning system in Embodiment 1 of the present invention.

[0034] like figure 1 As shown, the vehicle fatigue driving warning system includes: camera, image processor, controller, memory, timer and vibrator.

[0035] The camera collects the driver's face image in real time.

[0036] The image processor extracts the driver's facial features and fatigue features from the images captured by the camera. In this embodiment, the facial features are rotation scale invariant features and Haar wavelet features, and the fatigue features are eye detail features.

[0037] Controller, preset timing time is 3 hours.

[0038] The controller uses the initial rotation scale-invariant features and Haar wavelet features of the image processor to use the Gaussian mixture model to establish a facial feature model, and the eye detail features to establish a fatigue feature model, and store the facial feature mod...

Embodiment 2

[0054] image 3 It is a structural schematic diagram of the vehicle fatigue driving warning system in the second embodiment of the present invention.

[0055] like image 3 As shown, the vehicle fatigue driving warning system includes: camera, image processor, controller, memory, timer, sound alarm and vehicle stop running detector.

[0056] The camera is used to collect the driver's face image in real time.

[0057] The image processor extracts the driver's facial features and fatigue features from the images captured by the camera. In this embodiment, the facial features are Haar wavelet features and edge direction features, and the fatigue features are eye detail features.

[0058] The vehicle stop running detector is connected with the vehicle driving system, can detect whether the vehicle stops running, and can detect the time when the vehicle stops running.

[0059] Controller, preset timing time is 4 hours.

[0060] The controller uses the initial Haar wavelet feat...

Embodiment 3

[0078] Figure 5 It is a structural schematic diagram of the vehicle fatigue driving warning system in Embodiment 3 of the present invention.

[0079] like Figure 5 As shown, the vehicle fatigue driving warning system includes: a camera, an image processor, a controller, a storage unit, a timer, an odor alarm and a display screen.

[0080] The camera is used to collect the driver's face image in real time.

[0081] The image processor extracts the driver's facial features and fatigue features from the images captured by the camera. In this embodiment, the facial features are Haar wavelet features and edge direction features, and the fatigue features are eye detail features.

[0082] The storage unit is divided into two parts: a local memory and a remote server-side memory. Data exchange can be performed between the local memory and the remote server-side memory to realize synchronous data update. The storage unit pre-stores the identity information of the registered drive...

Abstract

The invention provides a vehicle fatigue driving warning method which is characterized by comprising the following steps: step A, an initial image is acquired, features are extracted, models are established, and timing is started; step B, an image of a driver is acquired; step C, when the driver meets the preset facial feature determining conditions and comparison between the current features and the feature models shows that the driver is not the registered one, the facial feature model and the fatigue feature model are reestablished, timing is restarted, and the method goes to step B, and when comparison between the current features and the feature models shows that the driver is the registered one or the driver does not meet the preset facial feature determining conditions, the method goes to step D; and step D, the current fatigue features are extracted, and alarm information is sent when the driving is judged to be fatigue driving according to the current fatigue features and the fatigue feature model, wherein alarm information is sent when the preset timing period is up. The advantage lies in that fatigue driving of drivers is judged comprehensively and fatigue driving warning is carried out more efficiently and reliably so as to ensure the safety of vehicle driving.

Description

technical field [0001] The patent of the present invention relates to the field of vehicle safety driving control, in particular to a vehicle fatigue driving early warning method and system. 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 dangerous driving. [0003] The simple method of counting vehicle driving time has the following disadvantages: firstly, due to individual differences, the same continuous driving time, for different individuals, the fatigue level is different; secondly, although the vehicle ...
