音频可视化在车辆外灯系统灯光秀的应用研究

Application of Audio Visualization in Lighting Show of Vehicle Exterior Light System

LED光源在汽车灯具设计中的大量应用,推动了灯具造型(尤其是贯穿式前后灯)以及灯具电子控制的快速发展,催生了灯光系统新的应用场景--灯光秀。本文围绕音频可视化、特征提取、音频节拍检测、灯光设计、架构设计,描述了车辆外灯系统灯光秀的功能实现方案,并通过制作的动画与原始音频结合成视频的方式,对方案的效果进行前期评审验证。该方案可实现基于音频可视化实时展现灯光秀,在汽车开发领域具有创新性和前瞻性。

LEDs have been applied widely in the design of automotive lamps, which has promoted the rapid development of lamp styling(especially through-type front and rear lamps) and electronic control of lamps, and has given birth to a new application scenario for lighting systems--lighting shows. This article focuses on audio visualization, feature extraction, beat detection, lighting design, and architecture design. It describes the function implementation scheme of the vehicle exterior lighting show, and conducts a preliminary review of the scheme effects by combining the produced animation and the original audio into a video. The solution can realize real-time display of light show based on audio visualization, and is innovative and forward-looking in the field of automobile development.
