Problems solved by technology

Due to different palms, the enhancement effect on infrared light is also different, resulting in the recognition effect is not very stable and fast
And due to reasons such as height and safety, players cannot touch all parts of the wall in all directions, so as to give players a more comprehensive interactive game experience

Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] Such as figure 1 As shown, a method for tracking infrared facula of a wall image, including:

[0034] S101. Capture wall images in real time through at least one camera;

[0035] S102. Preprocessing each frame of the wall image sequentially through the OpenCV vision library to obtain a black and white image corresponding to each frame of the wall image, wherein the white image spot in the black and white image is an infrared spot;

[0036] S103. Match the infrared light spots in the black and white image of the current frame with the infrared light spots in the previous black and white image to obtain a matching result.

[0037] S104. According to the matching result, the state and state duration of each in...

Abstract

The present invention discloses a method and system for tracking an infrared spot in a wall image. The method comprises: S1. capturing a wall image by using at least one camera; S2. preprocessing each frame of the wall image sequentially by using an OpenCV vision library, to obtain a black-and-white image corresponding to each frame of the wall image, wherein an image light spot in the black-and-white image is an infrared spot; S3. matching an infrared spot in a black-and-white image of a current frame with an infrared spot in a black-and-white image of a previous frame, to obtain a matching result; and S4. according to the matching result, carrying out identification to obtain a state and state duration of each infrared spot. The beneficial effects of the method and system disclosed by the present invention are as follows: by matching and determining the infrared spots in the adjacent frames of the image, the state and the state duration of each infrared spot are obtained, so that tracking and identification of the infrared spots are realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for tracking infrared light spots of wall images. Background technique [0002] Most of the existing wall interaction systems allow players to directly interact with the wall to experience the game. Infrared rays will have a good interference enhancement effect, thereby generating irregular infrared light spots on the wall, and by identifying these infrared light spots, order the game application to perform simple functions such as exploding and disappearing virtual objects, dragging and so on. Due to the different palms, the enhancement effect on infrared light is also different, resulting in the recognition effect is not very stable and fast. And due to reasons such as height and safety, players cannot touch all places on the wall in all directions, so as to give players a more comprehensive interactive game experience.
