Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the technical solutions of the present invention is provided with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present invention provides a touch screen control method, including the following steps:
acquiring an image of an object located at a preset position;
comparing the image with a pre-stored image;
when the image is the same as the pre-stored image, controlling the touch screen to enter a state to be activated;
receiving a control instruction sent by a user through a touch screen;
and controlling the touch screen to enter a corresponding working mode according to the control instruction.
The embodiment of the invention provides a touch screen control method, which comprises the steps of firstly obtaining an image of an object located at a preset position; then comparing the image with a pre-stored image; when the image is the same as the pre-stored image, controlling the touch screen to enter a state to be activated; then receiving a control instruction sent by a user through a touch screen; and finally, controlling the touch screen to enter a corresponding working mode according to the control instruction. The control method of the embodiment of the invention enables the touch screen to enter the state to be activated through image recognition without pressing keys; meanwhile, after the touch screen enters the to-be-activated state, the corresponding working mode can be entered only according to the control instruction sent by the user through the touch screen, the screen is not required to be lightened, energy is saved, meanwhile, the awakening time is short, and the touch screen can enter the corresponding working mode quickly.
As an optional implementation manner of the embodiment of the present invention, acquiring an image of an object located at a preset position includes: and acquiring an image of an object at a preset position through a camera module arranged on the touch screen. Further comprising: acquiring the duration of the object at a preset position;
and when the duration is not less than the preset duration, acquiring an image of the object at the preset position.
Illustratively, the camera module sets up the position in the middle of the last border of touch-sensitive screen. The preset position is 20cm to 80cm right above the camera module, and the preset time is 2 s; when the object is located 20cm to 80cm right above the camera module and lasts for 2s, the camera module is controlled to acquire the image of the object.
After the image is obtained, calculating the similarity between the image and a pre-stored image, wherein the specific way of calculating the similarity is a common technical means in the field of image recognition and is not detailed herein; when the similarity is greater than or equal to the preset similarity, judging that the image is the same as the pre-stored image; and when the similarity is smaller than the preset similarity, judging that the image is different from the pre-stored image. It should be noted that, because the distances between the object and the camera are different, and the features such as the sharpness of the captured image are different, the similarity between the calculated image and the pre-stored image is different, and therefore, when the preset similarity is fixed, a situation of an error in the determination result may occur. Specifically, the distance from the object to the camera module is obtained, and different preset similarities are adopted according to the distance.
As a preferred implementation manner of the embodiment of the present invention, the pre-stored image is a palm, that is, the palm is used to control the touch screen to enter a state to be activated;
when the touch screen enters a to-be-activated state, the touch screen is still in a black screen state, the screen is not required to be lightened, and the position information of the touch screen clicked by a user is received; and generating a control instruction according to the position information. Specifically, the duration of clicking the touch screen by the user is obtained; and when the duration time is more than or equal to the preset time (such as 1s), acquiring the position coordinate of the touch screen clicked by the user, and taking the position coordinate as position information. Further, matching the position coordinates with a preset area; acquiring a working mode corresponding to the matched preset area; and generating a control instruction for controlling the touch screen to enter the working mode.
For example, the operation modes corresponding to the regions of the touch screen are as shown in fig. 2, and after the touch screen enters the to-be-activated state, when the touch screen is pressed by a finger, the touch screen detects the coordinates of the pressed position, and compares the detected coordinates with the coordinates prestored in the system. When the position coordinate is confirmed to fall in the area A, the touch screen directly enters a shutdown state from a dormant state; when the position coordinate falls in the area B, the touch screen directly enters a preset working mode 1 corresponding to the area; when the position coordinate falls in the area C, the touch screen directly enters a preset working mode 2 corresponding to the area; when the position coordinate falls in the D area, the touch screen directly enters a preset working mode 3 corresponding to the D area.
At the moment, the touch screen is in a state to be activated, and the touch screen is still in a black screen state, so that the corresponding working mode can be entered by directly clicking the corresponding position. When the shutdown area is clicked, the touch screen is directly shut down in a black screen state, the touch screen is not required to be shut down after a system is started, the system starting time is saved, the touch screen is not required to be lightened, the energy is saved, and the service life of the touch screen can be prolonged.
