AI Technical Summary

Technical Problem

The existing KTV lighting control methods are low in intelligence, and they cannot analyze deep characteristics such as song emotional labels and chorus time points. The lighting effects are out of touch with musical emotions, lack separation and detail adjustment of vocals and accompaniment signals, cannot perceive personnel distribution and movement amplitude in real time, the lighting focus is fixed, and the performance subject cannot be dynamically tracked or respond to group interactions. The lighting system cannot automatically switch safety warnings or comfort modes according to the environmental status, resulting in waste of energy or insufficient effects.

Method used

By extracting song feature data, the lighting theme template is generated, the vocals and accompaniment signals are separated, the personnel distribution and motion amplitude are obtained using infrared thermal imaging and millimeter wave radar, the sound and light resources are dynamically allocated, and the lighting color temperature and brightness are automatically adjusted in combination with environmental parameters to achieve deep fusion and interactive response between light and music.

Benefits of technology

It realizes the deep integration of lighting and music, enhances user immersion and interactive experience, optimizes indoor comfort, adapts to different scenario needs, reduces energy consumption and improves the effect, and generates comprehensive control signals through the linkage of music analysis, sound source separation and personnel perception modules, and improves the intelligence of the lighting system.

Abstract

The invention discloses a KTV intelligent light control method and device. The method comprises the following steps: S1, extracting song feature data from a song requesting system, wherein the song feature data comprises low-frequency energy EL, a rhythm feature Tbeat, an emotion label Cemtion and a refrain time point tcorus; s2, generating a light theme template based on the Cemtion and the Tbeat, and setting a switching time point; s3, separating the microphone signal X (t) into a human voice track V (t) and an accompaniment track A (t) through a pre-trained real-time source separation model; s4, adjusting spotlight parameters according to the volume VdB and pitch change rate # imgabs0 # of the human voice track V (t), and driving an atmosphere lamp according to the frequency spectrum of the accompaniment track A (t); s5, acquiring a personnel distribution thermodynamic diagram H (x, y) through an infrared thermal imaging sensor, and acquiring an action amplitude parameter Mlevel through a millimeter wave radar; and S6, fusing personnel distribution and motion amplitude data. According to the invention, KTV intelligent light control can be carried out more intelligently.
