摘要
详细介绍了由计算机、数码相机及相关软件组成的现场逐点校正系统,以及对大型LED显示屏进行亮度、色度均匀性校正的方法。该方法首先对LED显示屏分区设置,然后采集亮度、色度等信息数据,并实现逐点校正。重点研究了利用数字图像处理技术,对采集的图片进行修正,达到为校正系统获取图片的方案。应用表明,该方案尤其适用于大型LED显示屏的现场校正,提高了LED显示屏的显示效果。
The system of sequential scanning on the spot based on computer, digital camera, and relative software and the methods of adjusting to uniformity of the brightness and chromaticity of the large size LED display screen are introduced in detail. The location of the large size LED display screen is set at first, and then the information of brightness and chromaticity and etc are collected. Sequential adjusting could be realized by this way. So the means of acquisition of images for the adjusting system by the process technology of digital images are studied, and the uniformities of brightness and chromaticity are improved.
