Automatic stage light tracking system and method based on limb motions

Abstract

The invention belongs to the technical field of automatic control, and discloses an automatic stage light tracking system and method based on limb motions. The automatic stage light tracking system comprises a camera-shooting calibrating tool kit, a target position recognition module, a stage modeling module, a hand recognition module, a Kalman filter, a three-dimensional information position locating module and a controller. The camera-shooting calibrating tool kit conducts camera calibrating; the target position recognition module uses two cameras to conduct camera calibrating; the stage modeling module conducts initializing modeling. Through the cameras, three-dimensional coordinates of a target object are obtained, and wearing is not needed; the interference degree of a sound electromagnetic wave by light signal transmission can be omitted; the Kalman filter conducts prediction (inertia prediction), and the position of a host at the next second is calculated; a gesture language controls light, and when the host meets emergencies, a light switch can be controlled through the gesture language.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an automatic tracking system and method for stage lights based on body movements. Background technique [0002] The lighting system of the stage is a necessary means to better render the artistic effect of the stage. In order to better highlight the central figure on the stage, the lighting system must be updated according to the movement of the central figure. In the current stage performance, the lighting There are three main control methods: (1) Manual control. During the performance, the staff needs to manually control the follow spot light at a higher place, so that the light beam always follows the movement of the actors performing on the stage. It takes a long time to cooperate with the practice before the performance, and it is time-consuming and laborious, and the effect is not good. And background personnel need to operate at high altitude, which...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing stage lighting control system cannot satisfy the requirement that the lights accurately follow the actors on the stage, the tracking time is delayed, and the tracking position has errors.
