Background Color Correction Based on Coefficient Matrix
System parameters and shooting conditions influence digital cameras and other image acquisition equipments. With a real background, a partial color and distortion phenomenon results in a large error in automatic color matching. In this study, we made 98 green swatches. The chromaticity value of swatch acquired using digital camera imaging equipment was considered an independent variable, whereas the true color chromaticity value obtained from the test spectrum was considered a dependent variable. Then, a coefficient matrix equation was constructed and solved. The resulting coefficient matrix was used for background color correction. The results show the image color information obtained by digital equipment after the application of the correction coefficient matrix. In addition, the average color difference with real background color is less than 3, which meets the requirements of camouflage performance and lay the foundation for the high fusion camouflage background color reproduction technology.
