Stage lighting automatic tracking system and control method thereof

Abstract

The invention discloses a stage lighting automatic tracking system and a control method thereof. The stage lighting automatic tracking system comprises a transmitting device, a stage light source device, host computer software and a camera device. The transmitting device is detachably mounted on a target to be tracked. The stage light source device is used for tracking the target to be tracked. The camera device is used for detecting the position of the transmitting device and capturing an image of the target, and transmitting the image and a position signal to the host computer software. Thehost computer software is provided with an OpenCV computer vision library and a DMX512 console. The OpenCV computer vision library is used for processing the image sent by the camera device, extracting, identifying and tracking the target according to the color in the image, then calculating the offset position of the target relative to the illumination direction of a stage light source, and sending the calculated position to the stage light source device through the DMX512 console. The stage light source device controls the illumination direction towards the target, so that the stage lightingcan automatically track the target movement. Compared with the prior art, the stage lighting automatic tracking system and the control method thereof provided by the invention have the beneficial effects of simple operation, strong practicability, wide application range and good anti-interference.

Description

technical field [0001] The invention relates to a stage light control system, in particular to an automatic stage light tracking system and a control method thereof. Background technique [0002] The existing stage lighting equipment roughly has the following types: [0003] Ordinary lighting equipment group with manual direction control: This type of equipment requires personnel to manually adjust the direction and brightness of the light during operation. Different light groups need to be controlled by different personnel. Due to personnel fatigue or delayed response, the accuracy of use is poor. , and require a lot of manpower. [0004] Stage lighting automatic tracking system with multiple pressure sensors detecting the position of the target: the operation of this type of system is mainly to detect the position of the target in real time by arranging multiple detection devices (pressure sensors) on the stage, control the direction of light irradiation, and realize the ...

AI Technical Summary

Problems solved by technology

The disadvantage of this type of system is that multiple positioning base stations need to be arranged on the stage, and the distance between the positioning base stations must be accurately measured. When the positioning base station or microphone (positioning device) encounters obstacles, the position of the positioning target will be disturbed. In addition, there is an error in the measurement distance of the wireless communication positioning module itself, which leads to inaccurate positioning and affects the accuracy of the light following the target movement

[0006] The above-mentioned existing stage lighting control system requires manual monitoring and manual operation, and there are some automatic tracking solutions, but there are application limitations and are susceptible to external interference
