Embodiment 1

[0057] For example, the electronic device is a large-sized tablet computer, and the object to be recognized is a mobile phone. There are two high-frequency cameras above the display screen of the large-size tablet computer. When the user places the mobile phone on the surface of the touch display screen, the tablet computer detects that an object to be identified by the user is placed on the touch screen according to the piezoelectric effect generated by the mobile phone and its surface. Then, the tablet computer caches the third image originally displayed on the touch screen in the graphics card, and at the same time, the tablet computer generates a control command to control the tablet computer to read a pure black image that is also stored in the graphics card image and display it on the touch screen. Next, according to the above control instructions, control the two high-frequency cameras to shoot the surface of the touch display unit to obtain two second images, and then ...

Embodiment 2

[0059] For example, the electronic device is a laptop computer, and the object to be recognized is a mobile phone. The notebook computer is connected to two high-frequency cameras located on the left and right sides of its display screen. When the user places the mobile phone on the surface of the display screen, the user clicks the "PrtSc" screen capture button on the keyboard. When the notebook computer receives the user's operation Finally, the notebook computer caches the third image originally displayed on the display screen in the graphics card, and at the same time, generates a control command to control the notebook computer to read a pure white image also stored in the graphics card, and display it on the touch screen on the display. Next, according to the above control instructions, control the two high-frequency cameras to shoot the surface of the touch display unit to obtain two second images, and then perform camera calibration, perspective transformation and furt...

Abstract

The invention discloses an identification method and an electronic device. The method is applied to the electronic device. The electronic device comprises a display unit. The method comprises the steps that when an object to be identified is placed on the display unit, a default image which is stored in the electronic device is read, wherein the variety of the colors of the default image is less than a threshold value; the default image is displayed in a first region of the display unit, wherein at least a part of the object to be identified is placed in the first region; at least one image acquisition device which is built in or externally connected with the electronic device is used to acquire a first image, wherein the first image is an image which comprises the image of the object to be identified; the first image is processed; and the object to be identified is identified.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a recognition method and electronic equipment. Background technique [0002] With the development of science and technology, users can perform multiple identifications through image acquisition devices, such as cameras, such as face recognition, iris recognition, and gesture recognition. [0003] At present, in addition to the above recognition technology, there is also an object recognition technology that puts at least one object on a platform, one or more of these objects are objects to be recognized, and the platform can be a display screen. After the user puts the object to be identified on the platform, the electronic device shoots the platform through at least one camera, at least one image taken will include the object to be identified, and then image processing is performed on the at least one image taken , so that its foreground is separated from the background, and th...
