How application-specific color calibration impacts multispectral imaging

摘要

Line scan multispectral cameras perform measurements for fast, pixel-wise spectral and colo-rimetric information based from scan surfaces such as spectral reflectance or CIE-Lab color space coordinates, respectively. Multispectral imaging cameras acquire various spectral image channels, typically more than the three channels acquired by conventional RGB cameras. Chosen for calibration testing was a Chromasens (Konstanz, Germany; www.chromasens.com) truePIXA multispectral camera, which acquires 12 distinct spectral image channels in the visible range of the light spectrum through a multichannel CCD line sensor.
