Image processing method and electronic device

Abstract

The invention provides an image processing method and an electronic device. An image acquisition unit in the electronic device is capable of collecting a first image which comprises a projected image and a background image and a second image which only comprises a background image. The method includes that the first image and the second image are carried out processing according to a first pre-set rule and a third image is obtained, wherein, the third image only comprises a projected image. Then, the third image is carried out an image binaryzation processing; a fourth image after the image binaryzation processing is obtained. At last, the fourth image is carried out processing according to a second pre-set rule and outline information of the projected image in the fourth image is obtained. Technical Problems that in the existing technology, the background image and the projected image of the images are difficult to tell and a projection interaction device cannot accurately detect the outline and the vertex of the projected image caused by the outside environment and illumination as well as the time of exposure of the image acquisition unit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an image processing method and electronic equipment. Background technique [0002] With the advancement of electronic technology, various interactive devices have appeared in the existing technology, such as projection interactive devices. Users can use laser pointers to perform corresponding operations on the projection screen. Specifically, projection interactive devices can The camera collects the image on the projection screen, so as to determine the position of the laser point in the image, and then responds according to the determined position, thereby realizing remote control of the electronic device through the laser pointer. [0003] The inventor of the present application found that the following technical problems or defects existed in the prior art during the implementation of the present invention: [0004] Accurately locating the target area in the process of p...

Problems solved by technology

[0005] The present invention provides an image processing method and electronic equipment, which are used to solve the problem that the background image in the image is difficult to distinguish from the projected image due to the influence of external ambient light and the exposure time of the image acquisition unit itself in the prior art. , leading to the technical problem of inaccurate detection of the contour and vertices of the projected image by the projection interactive device. The specific technical solution is as follows:
