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 invention discloses a method and system for tracking infrared light spots on a wall image. The method includes: S1, capturing the wall image through at least one camera; S2, sequentially preprocessing each frame of the wall image through the OpenCV visual library to obtain The 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; S3, matching the infrared spot in the black-and-white image of the current frame with the infrared spot in the previous black-and-white image to obtain Matching result; S4. According to the matching result, identify and obtain the state and state duration of each infrared spot. The beneficial effect of the present invention is: by matching and judging the infrared light spots in adjacent frame images, the state and state duration of each infrared light spot are obtained, thereby realizing the tracking and identification of the infrared light spots.

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.
