Abstract

The invention is suitable for the field of image processing and provides a target locating method and device as well as an image display device. The method comprises the following steps: obtaining a pixel coordinate of an image formed by a monochrome light source on a target on a photosensitive element, and then calculating a space coordinate of the monochrome light source on the target according to the pixel coordinate of the image and the space coordinate of an optical imaging element, wherein the image is the image leaved on the photosensitive element after the monochrome light source passes through the optical imaging element on the image display device, and the optical imaging element comprises a convex lens or a small hole containing a film optical filter. According to the embodiment of the invention, the image display device is used for calculating the space coordinate of the monochrome light source by obtaining the pixel coordinate of the image formed by the monochrome light source on the target on the photosensitive element; the speed of analyzing the monochrome light source is high; and under the filtration action of the optical filter, the problem of easily formed interference among lights is solved.

Description

【Technical field】 [0001] The invention belongs to the field of image processing, and in particular relates to a target positioning method, device and image display equipment. 【Background technique】 [0002] Nowadays, people's requirements for entertainment equipment are getting higher and higher, and they are no longer satisfied with only using the mouse, keyboard, remote control, etc. to operate the entertainment equipment, but hope that the entertainment equipment can automatically recognize the user's actions, and achieve The purpose of the control device. [0003] The existing technology provides a method for identifying user actions, that is, installing a camera on the entertainment device, capturing a two-dimensional image through the camera, and analyzing the two-dimensional image to obtain the user's action. Although this method can identify the user's action, However, there are the following disadvantages: first, the camera must capture a two-dimensional image and ...
