Color checker reflectance
WebWith the development of remote sensing technology, the simultaneous acquisition of 3D point cloud and color information has become the constant goal for scientific research and commercial applications in this field. However, since radar echo data in practice refer to the value of the spectral channel and its corresponding energy, it is still impossible to obtain … WebBy performing spectral reflectance measurements in situ on darkened areas of the painting and on paint-outs of comparable unaltered colors, using Kubelka–Munk turbid media theory, imaging the ...

WebThe left half of each cow has the spectral reflectance of the GretagMacbeth Color Checker, while the right half is a Metameric black that has been specially calculated to maximize color difference under Illuminant A. This type of target is designed to test both illumination and spectral responsivities for digital imaging solutions.
