The real-time and high-dynamic range multi-spectral imaging system, specially developed for the case of moving scenes, plays an important role in the fields of color science and many other relative technologies. In this project we will firstly study the hardware technology of the real-time and high-dynamic range multi-spectral imaging system. Then we will focus on the method of the color appearance reconstruction from the data-cube captured by our hardware system, according to the variation in illuminance, luminance, glossy, geometry and so on. Base on the ordinary optical components and image sensors, we will set up a set of the high-dynamic range multi-spectral imaging system. By use of our system, we can simultaneously get the data-cube of high-dynamic range multi-spectral image from the moving objects and scenes. And we will also focus on the spectrum and color reconstruction method for such system based on the color image appearance theory and visual-psychological perception assessments..The results of the project will be of much benefit to the development of the hardware and software technoloies of the real-time and high-dynamic range multi-spectral imaging system.
