The details will be described below separately.
The embodiment will be described from the perspective of a smart navigation device, which may be specifically integrated in a terminal, where the terminal may be an electronic device with network function, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer).
Referring to fig. 1, fig. 1 is a schematic view of a scene architecture of an intelligent navigation method according to an embodiment of the present invention, including a terminal and a server, where the terminal and the server establish a communication connection through the internet.
The user sends a navigation request to the server through the terminal, the navigation request comprises destination information, the server generates a navigation route according to the destination information and the current road condition information after receiving the navigation request, and the server sends the navigation route to the terminal.

The terminal may be a mobile terminal, such as a mobile phone, a tablet computer, or a conventional PC (personal computer), which is not limited in the embodiments of the present invention.
Referring to fig. 2, fig. 2 is a schematic flowchart of an intelligent navigation method according to an embodiment of the present invention, where the intelligent navigation method includes:
step S101, in the process that the terminal plays the navigation data, a first image of eyes of a user is obtained through a camera of the terminal.
In the embodiment of the invention, in the process of playing the navigation data by the terminal, the eye image of the user can be acquired by the terminal camera (such as an infrared camera). Wherein the eye image may include: an iris image region including an iris image, and a sclera image region including a sclera image. In addition, the navigation data includes image data and voice data.
Specifically, the embodiment may determine a face image from a current picture captured by the terminal camera, and then further extract an eye image from the face image. For example, a current image may be captured at each set time, a face image may be obtained from the image according to a face recognition technique, an eye image may be extracted from the face image, and feature information in the eye image may be further extracted. This step is to take a shot once every set time, for example, take an image once every 2 seconds, where each shot may be to take multiple images in succession, for example, 10 images at a time.
The face recognition is a biometric technology for identity recognition based on face feature information of a person. The method comprises the steps of collecting images or video streams containing human faces by using a camera or a pick-up head, automatically detecting and tracking the human faces in the images, and further carrying out a series of related technologies of the faces on the detected human faces. The face image contains abundant pattern features, such as histogram features, color features, template features, structural features, Haar features, and the like. In the embodiment, the useful information can be picked out, and the face detection can be realized by using the characteristics.
In one embodiment, the face recognition may be performed by using the Adaboost algorithm, which is a method for classification and combines some weaker classification methods to form a new strong classification method. In the process of face detection, an Adaboost algorithm is used for picking out some rectangular features (weak classifiers) which can represent the face most, the weak classifiers are constructed into a strong classifier according to a weighted voting mode, and then a plurality of strong classifiers obtained by training are connected in series to form a cascade-structured stacked classifier, so that the detection speed of the classifier is effectively improved.
In an embodiment, after the face image is obtained by using the face recognition technology, the face image may be further preprocessed. The image preprocessing of the human face is a process of processing the image and finally serving for feature extraction based on the human face detection result. The original face image acquired by the terminal is limited by various conditions and random interference, so that the original face image cannot be directly used, and the original face image needs to be subjected to image preprocessing such as gray correction, noise filtration and the like in the early stage of image processing. For the face image, the preprocessing process mainly includes light compensation, gray level transformation, histogram equalization, normalization, geometric correction, filtering, sharpening, and the like of the face image.
Step S102, judging whether the user watches the screen of the terminal at present according to the first image of the eyes of the user, if not, executing step S103, and if so, continuing to execute step S102.
The method for judging whether the user watches the terminal screen currently according to the eye image can be various, for example, the terminal can extract visual angle focus information in the eye image, the visual angle focus information can include a focus position, whether the focus of the user's eyes is located in the terminal screen is judged according to the focus position, and if yes, the user can be determined to watch the terminal screen currently. Wherein, the view focal information may further include: the distance between the eyes of the user and the terminal, the relative angle between the terminal and the eyes and the like.
Specifically, as shown in fig. 3, the eyeball 2 is located at the center of the eye 1, and the pupil 3 is located at the center of the eyeball 2. The eyes of the user can be divided into four areas, namely, an upper left area, an upper right area, a lower right area and a lower left area, and the terminal screen is predetermined to be located in the target area of the eyes, for example, the terminal determines the relative position of the eyes of the user and the terminal according to an image acquired by the camera, the terminal determines the preset area of the terminal located in the eyes according to the relative position, and the preset area is the target area. In addition, the target area may be set according to a user operation, which is not further limited in the present invention. The terminal acquires the focal position of the eyes of the user according to the visual angle focal information in the extracted eye image, further determines the area corresponding to the focal position, judges whether the area is the target area of the terminal screen located in the eyes, and if so, determines that the focal point of the eyes of the user is located in the terminal screen, namely the user currently watches the terminal screen.
For example, as shown in fig. 4, for example, it is predetermined that the target area of the terminal screen located in the eyes is a lower right area, and it can be determined from the eye image that the current eyeball is also located in the lower right area of the eyes, so as to determine that the user is currently watching the terminal screen. After the camera acquires the eye image of the user, the relative position of the iris on the whole eye and the relative position of the pupil on the eyeball can be judged by utilizing the difference between the color of the iris in the eye image information and the color and the lines of the other parts of the eye through the image recognition and positioning technology, and then the region of the eyeball in the eye is determined.
In one embodiment, as shown in fig. 5, the parts of the eyeball 2 in the eye image respectively fall into four regions, namely, the upper left region, the upper right region, the lower right region and the lower left region, and then the area of the eyeball 2 falling into the above regions can be respectively calculated, and the area of the eyeball 2 falling into the lower right region can be calculated to be the largest, so that the current lower right region of the eye can be determined.
In order to prevent an incorrect operation, in the embodiment of the present invention, before determining whether the user currently gazes at the terminal screen according to the eye image, a distance between the terminal and the user ' S eyes is measured to determine whether an operation of extracting visual angle focus information data of the user ' S eyes needs to be started, and when the terminal is beyond a certain range from the user ' S eyes, the execution of the extraction operation is abandoned, so that before step S102, the method may further include:
detecting the distance between the terminal and the eyes of the user through scanning infrared rays emitted by the camera, and when the detected distance between the terminal and the eyes of the user is within a preset threshold range, executing extraction operation by the camera to extract visual angle focus information data of the eyes of the user; and when the detected distance between the terminal and the eyes of the user exceeds a preset threshold value range, the camera abandons the execution of the extraction operation. The distance between the terminal and the eyes of the user can be detected by scanning infrared rays emitted by the camera, for example, the distance between the eyeball and the camera can be calculated by comparing the difference between the time when the scanning infrared rays emitted by the camera are emitted and the time when the scanning infrared rays return to the camera after hitting the eyeball with a constant value of 30 kilometers per second.
Step S103, stops playing the image data and turns off the screen of the terminal.
And if the user is judged not to watch the terminal screen at present, the playing of the image data can be stopped, and the terminal screen is extinguished, so that the electric quantity of the terminal is saved. It should be noted that after the terminal screen is turned off, the terminal may further continue to play the voice data in the navigation data to prompt the user to proceed.
The screen of the terminal may be divided into an active Light Emitting display device and a passive Light Emitting display device according to whether a display medium of the screen emits Light, the active Light Emitting display device is represented by an Organic Light-Emitting Diode (OLED), and the passive Light Emitting display device is represented by a Liquid Crystal Display (LCD), so that the screen brightness specifically includes panel display brightness or backlight brightness. In this embodiment, the terminal may save battery power of the terminal by turning off the terminal screen, and specifically, the terminal may turn off the display panel or turn off the backlight according to different screen types.
As can be seen from the above, the intelligent navigation method provided in the embodiment of the present invention can acquire the first image of the eyes of the user through the camera of the terminal in the process of playing the navigation data by the terminal, where the navigation data includes image data and voice data, and determine whether the user watches the screen of the terminal at present according to the first image of the eyes of the user, and if not, stop playing the image data and turn off the screen of the terminal. According to the invention, when the sight of the user does not pay attention to the terminal screen in the process of terminal navigation, the screen is automatically closed, so that the power consumption of the terminal can be effectively reduced, the waste of electric quantity is avoided, and the user experience is improved.
The intelligent navigation method of the present invention will be further explained below according to the description of the previous embodiment.

The terminal acquires the focal position of the eyes of the user according to the visual angle focal information in the extracted eye image, further determines the area corresponding to the focal position, judges whether the area is the target area of the terminal screen located in the eyes, and if so, determines that the focal point of the eyes of the user is located in the terminal screen.
And step S204, determining that the user does not watch the terminal screen currently.
In order to prevent the misoperation, the embodiment of the present invention may further measure the distance between the terminal and the user ' S eyes before the visual angle focus information in the eye image is extracted in step S202 to determine whether the visual angle focus information data extraction operation for the user ' S eyes needs to be started, and when the terminal is beyond a certain range from the user ' S eyes, the execution of the extraction operation may be abandoned.
Step S205 stops playing the image data and turns off the terminal screen.
And if the user is judged not to watch the terminal screen at present, the playing of the image data can be stopped, and the terminal screen is extinguished, so that the electric quantity of the terminal is saved. It should be noted that after the terminal screen is turned off, the terminal may further continue to play the voice data in the navigation data to prompt the user to proceed.
And step S206, continuously judging whether the user watches the terminal screen at present, if so, executing step S207, and if not, continuously executing step S206.
Specifically, the step of continuously determining whether the user is looking at the terminal screen may also include:
and acquiring a second image of the eyes of the user through the camera of the terminal, judging whether the user watches the screen of the terminal currently according to the second image of the eyes of the user, and if the user is confirmed to watch the screen of the terminal currently, continuing to execute the step S207.
Step S207, the screen of the terminal is lighted up and the playing of the image data is resumed.
In an embodiment, after determining that the user is currently gazing at the screen of the terminal, before lighting up the screen of the terminal and resuming playing of the image data, the method may further include:
acquiring the duration of a screen of a user concerned terminal;
judging whether the duration is longer than a preset duration or not;
and if so, executing the steps of lightening the screen of the terminal and recovering the playing of the image data.
As shown in fig. 7, fig. 7 is an application scenario diagram of the intelligent navigation method according to an embodiment of the present invention, and the method can determine whether the user focuses on the terminal screen currently, stop playing the image data and close the terminal screen to save power when the user does not focus on the terminal screen, and light the terminal screen and continue playing the image data when the user needs to view the navigation information.
