Problems solved by technology

[0005] Embodiments of the present invention provide a screen positioning method and device to solve the problem that when the distance between two devices is very close (less than 10 cm), the device with the smaller screen size cannot obtain a clear image of the device with the larger screen size through the camera. This makes it impossible to determine the corresponding position of a device with a smaller screen size on the screen of a device with a larger screen size

[0035] In the first embodiment, the flow chart of the method for determining the projection position of the second device on the screen of the first device by the first device is as follows: figure 1 shown, including the following steps:

[0036] Step 101: The first device receives the target RGB value sent by the second device, wherein the target RGB value is the RGB value of the center point of the preview image of the background image displayed by the first device acquired by the second device through the camera, the background image Divided into multiple areas, the number of pixels contained in each area is not greater than the preset value, the RGB values ​​of the pixels in the same area are the same, and the RGB values ​​​​of the pixels in different areas are different.

[0037] Specifically, the preview image refers to an image captured by the second device through the camera on the background image displayed by the first device, and the preview image is displayed on th...

[0053] In the second embodiment, the flow chart of the method for the first device to determine the projection position of the second device on the screen of the first device is as follows figure 2 shown, including the following steps:

[0054] Step 201: The second device obtains a preview image of the background image displayed by the first device through the camera, wherein the background image is divided into multiple regions, and the number of pixels contained in each region is not greater than a preset value, and the same region The RGB values ​​of the pixels in the center are the same, and the RGB values ​​of the pixels in different regions are different.

[0055] Preferably, the RGB values ​​of each region in the background image displayed on the screen of the first device meet the following conditions: in the horizontal direction, the R value, G value and B value of the RGB values ​​of any two adjacent regions Any value in satisfies the set first functional relations...

[0065] In the first specific embodiment, the flow of the method for a smart TV to determine the projection position of a smart phone on the screen of the smart TV is as follows: image 3 As shown, wherein, the distance between the smart TV and the smart phone is less than 10cm, including the following steps:

[0066] Step 301: The smart TV displays a background image on the screen, wherein the background image is divided into multiple areas, the number of pixels contained in each area is not greater than a preset value, and the RGB values ​​of the pixels in the same area are the same, The RGB values ​​of pixels in different regions are different.

[0067]In the implementation, the smart TV displays a solid color background image before displaying the background image divided into multiple regions with different RGB values ​​on the screen, that is, the RGB values ​​of all pixels in the background image are the set values, so as to determine the The acquired difference between ...

Abstract

The invention discloses a screen positioning method and apparatus, so that a problem that a device with a small screen size can not obtain a clear image of a device with a large screen size by a camera while the distance between the two devices is short and thus the corresponding position of the device with the small screen size in the screen of the device with a large screen size can not be determined can be solved. The method comprises: a first device receives a target RGB value transmitted by a second device, wherein the target RGB value is an RGB value of a center point of a preview image of a background image that is displayed by the first device and is obtained by the second device by a camera, the background image is divided into a plurality of regions , he number of pixel points included by each region is not larger than a preset value, RGB values of pixel points in the same region are identical and RGB values of pixel points in different regions are different; and the first device determines a projection position of the second device in a screen of the first device according to set positions of pixel points in the region corresponding to the target RGB value in the background image.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a screen positioning method and equipment. Background technique [0002] With the popularity and popularization of modern smart electronic devices, the interaction between devices is becoming more and more common in family or small area scenarios. Screen interaction is the most intuitive and convenient way of interaction between devices, and in many application scenarios, for example, the user performs corresponding operations on the game on the TV by operating the screen of the game displayed on the TV screen acquired by the mobile phone . After the TV determines and obtains the relative position of the mobile phone on the TV screen, it can perform corresponding operations according to the user's operation on the content displayed on the TV screen acquired by the mobile phone. [0003] In the prior art, the screen positioning method based on image recognition is usual...
