纹理投影面区域投影颜色补偿测试数据

针对多投影拼接显示时大投影面存在小块纹理区域需要颜色补偿的问题，本项目构建了纹理投影面区域投影颜色补偿测试数据。数据一共包括64幅颜色样本图片，分别对应投影颜色样本RGB三通道像素分别取20，100，150，230时，64幅颜色样本图片投影到浮雕幕上相机拍照采集的图像。数据量约为72MB，可用于N=4的基于薄板样条插值的投影颜色空间与拍照颜色空间的拟合以及补偿区域内、外的颜色拟合映射，有助于区域投影颜色补偿技术的发展。Aiming at the problem that small texture regions on large projection surfaces require color compensation during multi-projection tiled display, this project constructed test datasets for projection color compensation on textured projection surface regions. The dataset includes a total of 64 color sample images, each corresponding to images captured by a camera when projecting color samples with pixel values of the three RGB channels set to 20, 100, 150 and 230 respectively onto the embossed screen. The dataset has a total size of approximately 72 MB, and can be used for fitting between the projection color space and the captured color space based on thin plate spline interpolation when N=4, as well as color fitting and mapping within and outside the compensation regions, which contributes to the development of regional projection color compensation technologies.
