A Graphic Water Curtain System Based on ARM Architecture

摘要:

传统的以水为装饰的方法形式比较单一,缺乏创新性的现状,因此提出了一种基于ARM架构,结合了人体传感、无线传输等功能的数字图形水幕系统,能够精确控制电磁水阀开/闭合,实现了以水为媒介的图形、文字的展示；同时,在系统中开发了一种自由落体图像补偿算法,创建了图像补偿表,通过对原始图像的补偿可在系统人眼感兴趣的区域很好展示所需的图形及文字；在实验中可看出系统在1.26 m×1.26 m的显示区域内对64×64像素的图形进行补偿时达到了较好的效果；该系统综合考虑了性能、成本等因素,具有很强的创新性和实用价值。

Abstract:

As to the status that the form relatively simple and lack of innovation for water as decoration in traditional method , this paper describes a novel digital graphic water curtain system, which based on the ARM architecture and combined with the body sensing, wireless transmission and other functions. It can display graphics, text that water as the medium by controlling the solenoid valve open / close precisely. Meanwhile, it developed a free-fall image compensation algorithm and created the image compensation table in the system, Graphics and text can be well demonstrated in the area that human interest by compensation to the original image. the system compensation can achieve good results as to graphic of 64 × 64 pixel in 1.26m × 1.26m display area in the experiment.The system comprehensively considered performance, cost and other factors, has a strong innovative and practical value.
