Problems solved by technology

[0003] However, with this method, due to contrast errors, there is no way to clearly extract the target image, and the extracted target image is incomplete or the background object (such as the above-mentioned tablet computer) is recognized as the target image. In addition, due to the environment (such as light) The impact may also cause the target image not to be extracted

Abstract

The embodiment of the invention provides an image extraction method and device, relating to the image field and used for accurately extracting target images. The method comprises obtaining a first image, receiving the infrared light reflected by a reference body and obtaining a second image in dependence on the reflected infrared light; wherein the second image corresponds with the first image; the first image and the second image are sent to an image processing device, so that the image processing device maps the second image with the first image and extracts target images from the first image in dependence on the second image. The image extraction method and device are used for extracting images.

Description

technical field [0001] The present invention relates to the image field, in particular to an image extraction method and device. Background technique [0002] In the prior art, the user can obtain the image of the object through the camera, and extract a target image from the image through the computer. Generally, the image includes the background image and the target image, and the computer will compare the image with the previously saved image. The image of the background image is compared, and the part with a larger deviation is the target image to be extracted. For example, the user places an object on the tablet computer, and the camera acquires an image including the tablet computer and the object, and the The image is compared with the image saved by the computer that only includes the tablet computer, so as to determine that the deviation part of the two images is the image of the object, and then determine that the image of the object is the target image that needs ...
