Embodiment 2

[0060] refer to figure 2 , which shows a flow chart of Embodiment 2 of a fatigue detection method of the present invention, which may specifically include the following steps:

[0061] Step 201. Obtain multiple frames of preview images including the face of the mobile terminal user continuously captured by the camera.

[0062] The mobile terminal can be provided with a camera (built-in or external), and then the camera can be used to continuously collect multiple frames of preview images including the face of the user of the mobile terminal. For example, in a driving scene, the on-board computer can continuously collect multiple frames of preview images through an external camera.

[0063] Step 202 , sequentially perform gray value difference calculation on each pixel of all two adjacent frames of preview images in the multiple frames of preview images.

[0064] In the embodiment of the present invention, one purpose of detecting the transition point from the normal state t...

Embodiment 3

[0112] refer to Figure 4 , which shows a flow chart of Embodiment 3 of a fatigue detection method of the present invention, which may specifically include the following steps:

[0113] Step 401. Obtain multiple frames of preview images including the face of the mobile terminal user continuously captured by the camera.

[0114] The mobile terminal can be provided with a camera (built-in or external), and then the camera can be used to continuously collect multiple frames of preview images including the face of the user of the mobile terminal. For example, in a driving scene, the on-board computer can continuously collect multiple frames of preview images through an external camera.

[0115] Step 402 , sequentially perform gray value difference calculation on each pixel of all two adjacent frames of preview images in the multi-frame preview images.

Abstract

An embodiment of the invention provides a fatigue detection method and a mobile terminal. The fatigue detection method is applied to the mobile terminal with a camera and includes: acquiring multiframe preview images, including the face of a user of the mobile terminal, continuously collected by the camera; subjecting the multiframe preview images to transition point detection; acquiring facial feature change information of the user of the mobile terminal when a transition point from a normal state to a fatigue state is detected; determining that the user of the mobile terminal is in the fatigue state on the basis of the facial feature change information; sending fatigue state prompting information to the user of the mobile terminal. According to the fatigue detection method, the prompting information can be sent out after detection of the fatigue state of the user, so that driving safety of the user of the mobile terminal can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a fatigue detection method and a mobile terminal. Background technique [0002] With the rapid development of the economy, the number of motor vehicles is constantly increasing. While motor vehicles bring quick and convenient transportation to human beings, they also bury hidden dangers for traffic safety. The driver's fatigue driving is an important factor affecting the driving safety of motor vehicles, and it is of great significance to prevent traffic accidents by detecting the driver's fatigue driving to prevent fatigue driving. [0003] At present, there are many commonly used fatigue detection methods, for example, to judge whether the driver is tired according to the change of the driver's grip on the steering wheel, but the detection is not accurate and there are many false alarms; or by detecting whether the driver's head is in a preset state , requiring t...
