  • LED Lighting Based Multispectral Imaging System for Color Measurement
    Publication number: 20180372542
    Abstract: An LED lighting based multispectral imaging system for color measurement is provided, including a main control computer and an enclosed type lamp box, where a digital camera is provided at the top of the lamp box, and an LED lamp set control apparatus, a drawer type bearing platform, and an LED lamp set are provided at the bottom of the lamp box. A to-be-measured object is placed on the drawer type bearing platform. The main control computer controls spectral power distribution of the LED lamp set to be in a reciprocal relationship with a spectral sensitivity curve of the digital camera and extracts a camera response and performs calculation, to obtain spectral reflectivity of each pixel of the to-be-measured object.
    Type: Application
