Method for distinguishing optical axis of camera in real time

Abstract

The invention discloses a method for distinguishing the optical axis of a camera in real time, relates to a method for distinguishing relative poses of objects in machine vision in real time, and belongs to the field of machine vision. The method comprises steps as follows: Step one, LED flickers are mounted on a game display screen, a high-speed camera for acquiring images of the LED flickers mounted on the screen in real time is arranged in a virtual gun, and backlight removal treatment is performed on the acquired images of the LED flickers mounted on the screen; Step two, the mapping relation between acquired LED flicker positions and actual positions of the LED flickers on the game display screen is established according to parity of point numbers of the LED flickers, acquired by the virtual gun in real time, on the game screen and the LED flickers, and the relative poses of the objects in machine vision are distinguished in real time. According to the method, the position of the optical axis of the camera in machine vision is distinguished through LEDs arranged on the game display screen and calculation of the virtual gun mapping position relation, and the method is high in distinguishing speed and high in result precision and is slightly interfered by the outside.

Description

technical field [0001] The invention relates to a method for real-time judging the optical axis of a camera, in particular to a method for real-time judging the relative pose of an object in machine vision, belonging to the field of machine vision. Background technique [0002] With the development of science and technology, the demand for human-computer interaction has become more and more. Adding human-computer interaction to electronic games will make the game more realistic and win the market. In the simulated shooting game, we need to calculate the coordinates of the virtual gun on the screen in real time. At this time, we must know the relative position of the virtual gun and the screen. [0003] The traditional method is to use laser positioning, that is, the laser is fired when the gun is fired, and the position of the laser can be obtained to obtain the shooting position of the virtual gun. This method has the following disadvantages: the effect of the laser on the...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: the effect of the laser on the strong light background is not ideal, and it is easily absorbed by the LED screen. The second point is that the laser has hidden dangers to the safety of human eyes.

The disadvantage is that the mechanical precision is high and the user experience is not good
