Automatic lamp light following method and system for stage

Abstract

The invention discloses an automatic lamp light following method and system for a stage. The method comprises the steps of obtaining the position information of a target on the stage in real time through a 3D camera above the stage, generating a corresponding follow spotlight angle adjusting command according to the position information of the target, and controlling follow spotlights to be subjected to corresponding irradiating angle offset adjustment according to the follow spotlight angle adjusting command. The position of the target on the stage is detected by the 3D camera, so that the angles of the follow spotlights of the stage are adjusted automatically to achieve automatic following of the stage lamp light, automation is achieved, manual control over the follow spotlights is not needed, the follow spotlights can be arranged at the positions above the stage or far higher than audiences accordingly and are prevented from injuring the audiences or workers in the running process,and the follow spotlights can also be used for directly irradiating the target so that the situation that a reflection mirror is used for reflecting light and consequently light beam losses are causedcan be avoided.

Description

technical field [0001] The invention relates to the field of light following, in particular to an automatic light following method and system for a stage. Background technique [0002] The use of stage lighting is an indispensable and important means in stage art to achieve the purpose of highlighting key points, shaping the image of characters, and enhancing the atmosphere of the environment. The stage light following device is a device used by stage performers to follow the light during stage activities. As part of the stage lighting follower, the follow spot light is a high-power spotlight, which is composed of a convex lens and a light source. It mainly uses light beams to highlight actors or supplement light for actors when the stage is dark. [0003] The existing stage light follower uses the profiling remote control synchronous light tracking device to realize the remote control operation of the light follower, but it has not realized automation. When the reflection ...

AI Technical Summary

Problems solved by technology

[0003] The existing stage light follower uses the profiling remote control synchronous light tracking device to realize the remote control operation of the light follower, but it has not realized automation. When the reflection automatic light tracker controls the light beam by controlling the reflector, the light is in the process of reflection It caused a non-negligible loss and seriously affected the effect, and the follow spot light was placed in the middle and rear part of the auditorium, which may hurt the audience or staff during operation

[0004] Therefore, how to realize the automatic tracking of stage lights, reduce the loss of light beams, and avoid hurting the audience or staff during operation is a technical problem that those skilled in the art need to solve at present.
