Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Eye tracking, which may also be referred to as gaze tracking, is a technique for estimating the gaze and/or fixation point of an eye by measuring eye movement. The sight line can be understood as a three-dimensional vector, and the fixation point can be understood as a two-dimensional coordinate of the three-dimensional vector projected on a certain plane.
In this embodiment, tracking the eyeball may be realized by an optical recording method. The principle of the optical recording method is to record the eye movement of the testee by using a camera or a video camera, that is, to obtain an eye image capable of reflecting the eye movement, and to extract eye features from the obtained eye image for establishing an estimation model of the sight line/fixation point. Wherein the eye features may include: pupil location, pupil shape, iris location, iris shape, eyelid location, canthus location, spot location (or purkinje spot), and the like.
Optical recording methods include pupil-cornea reflectometry. The principle of the pupil-cornea reflection method is that a light source irradiates the eyes, the eyes are shot by an image acquisition device, and meanwhile, the reflection points of the light source on the cornea, namely light spots, are shot, so that the eye images with the light spots are obtained.
Along with the rotation of the eyeball, the relative position relationship between the pupil center and the light spot is changed. And the collected eye images with the light spots can reflect the position change relationship, and the sight/fixation point is estimated according to the position change relationship.

In this embodiment, the device integrated with the eyeball tracking module may be used to acquire the eye movement information of the user, and the device may be a vehicle-mounted device, a mobile terminal, or a wearable device (such as glasses, a bracelet, a watch, and the like). In this embodiment, the device may establish a wired or wireless connection with a control system of the vehicle, and the control system may perform real-time detection on the performance state of the vehicle. When a vehicle breaks down due to a traffic accident or other accidents in the driving process, a control system of the vehicle sends vehicle fault information to equipment integrated with an eyeball tracking module, and when the vehicle fault information is received, the equipment starts to acquire eye movement information of a user. Or when the user is in an accident (such as hijacking by a ruffian), the device is started through voice or gesture actions, so that the device acquires the eye movement information of the user. Wherein the user may be a driver or any passenger in the vehicle, for example: if the device is a mobile device or a wearable device, the eye movement information of a user carrying or wearing the device is acquired.

And if the current time exceeds the preset time, alarm information is generated.
Wherein the set threshold may be set to any value between 3-10 seconds, for example, to 5 seconds. The set position may be any position in the vehicle, such as the center position of the steering wheel or the position of the lower frame of the rear view mirror. In this embodiment, when the device integrated with the eyeball tracking module is a vehicle-mounted device, the position watched by the user can be acquired through the gaze point information, and whether the duration of the gaze set position of the user exceeds the set threshold value or not can be acquired by analyzing the gaze point information of the multi-frame eye image. When the equipment integrated with the eyeball tracking module is a mobile terminal or wearable equipment, the gazing position of a user can be obtained through the gazing point information and the current three-dimensional coordinate information of the equipment, namely the gazing point information and the three-dimensional coordinate information of the equipment are comprehensively analyzed and then mapped to the corresponding position in the automobile, and whether the duration of the gazing set position of the user exceeds the set threshold value or not is obtained through analyzing the multi-frame eye images. Specifically, when the duration of the user watching a set position exceeds a set threshold, it can be determined that the user needs help at present, and then alarm information is generated.
Optionally, the determining whether the eye movement information satisfies the set condition may be implemented in the following manner: and judging whether the vital signs of the user are in a set danger range or not according to the eye movement information. And if so, generating alarm information.
In this embodiment, whether the user is unconscious or in a coma state can be determined by the pupil radius change information and the eyelid information. For example, by analyzing a plurality of frames of eye images, it is obtained that the eyes of the user are always in a closed state, and it can be preliminarily determined that the user is already in a coma state, or the eyelids of the user are always in a towering state, and it can be preliminarily determined that the consciousness of the user is low. When the vital signs of the user are within a set danger range, the user needs to be rescued in time, and at the moment, alarm information is generated.

Optionally, the alarm information is generated according to the eye movement information, and the method may be implemented in the following manner: positioning the current position of a user to obtain position information; and generating alarm information according to the position information and the eye movement information.
In this embodiment, a Global Positioning System (GPS) may be installed in the device integrated with the eyeball tracking module, and after the vehicle has a fault, the current geographic location of the user is located by the GPS, so as to obtain the current location information of the user. The position information and the eye movement information are combined to generate the alarm information, so that the rescue personnel can obtain the current position of the user in time to find the user in time, and can obtain the current vital sign state of the user according to the eye movement information of the user to prepare effective rescue measures.
Specifically, after the alarm information is generated, the alarm information is sent to the setting platform, so that the user can be rescued timely.
Optionally, after the alarm information is sent to the setting platform, the method further includes the following steps: and sending the alarm information to a mobile device associated with the vehicle-mounted device.
