Fabric color photographing measurement method based on nonlinear constraint interpolation

The invention discloses a fabric color photographing measurement method based on nonlinear constraint interpolation. Aiming at the limitation of a current spectrophotometer in the aspect of complex fabric color measurement, the invention provides a fabric color photographing measurement method based on nonlinear constraint interpolation according to the high relevance between fabric color data and a digital camera response value of the fabric color data. The device can be used for carrying out rapid non-contact color measurement on objects with irregular shapes, textile fabrics with complex patterns or special structures, slender yarns, soft colored cotton and the like, and is applied to fabrics with rich types and diversified structural forms. According to the method, subjective differences existing in traditional manual color matching are overcome, and the limitation of a spectrophotometer in practical application is solved. 本发明公开了一种基于非线性约束插值的织物颜色照相测量方法。本发明针对当前分光光度计在复杂织物颜色测量方面存在的局限性，依据织物颜色数据和其数码相机响应值之间的高度关联
