Embodiment Construction
[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0055] According to one or more embodiments, a disclosed fabric image color calibration algorithm based on spectral reflectance reconstruction, such as figure 1 and figure 2 shown, including the following steps:
[0056] Obtain the color training sample and the image of the fabric to be corrected through camera acquisition, obtain the actual system response of the color training sample and the image of the fabric to be corrected, and obtain the true spectral reflectance of the color training sample through a spectrophotometer;
[0057] Construct a virtual imaging system, define a virtual spectral response function, and calculate the virtual system response of all color training samples and their corresponding spectral reflectance estimates;
[0058] According to the color space conversion formula, the color space conversion is performed on the real spectra...
