基于机器视觉技术的LED灯具舞台照明智能控制

基于机器视觉相关技术,实现舞台照明LED灯光自动智能跟随与亮度调节功能。首先,研究分析无人时舞台照片的区域灰度值特征,并将其存储作为标准模板;其后,实时采集舞台照片,分析研究其区域灰度值特征,并与标准模板进行比较,初步检测是否存在目标对象;之后,提取目标对象特征,并进行识别,判断其是否为演员(人体),并发出相应控制信息,控制对应的LED灯开启、关闭,或者提高、降低亮度。可进一步实现舞台灯光光束光型的自动产生与智能变换控制,对于舞台照明灯光自动智能控制具有重要意义。

Intelligent Control of LED Lamps for Stage Lighting Based on Machine Vision Technology

The function of following person intelligently and automatically of LED lights for stage lighting is implemented based on machine vision technology in this paper. Firstly,the area gray value characteristics of stage photograph when no persons on are analyzed and stored as standard templates. Subsequently,the stage photos are acquired real- time and their area gray value characteristic are researched and compared with the standard templates,in order to detect whether there are target object or not. Then,the features of target object are extracted and distinguished,and the corresponding control information is conveyed to the LED lamps to control the LED lamps on,off,or raise and lower the brightness. Based on this paper,the automatic generation and intelligent conversion control of stage lighting beam type could be realized easily. It is significant for stage lighting control automatically and intelligently.
