Problems solved by technology

Since the color of an object depends on the reflectance and illuminance of the object, and color blindness is just unable to distinguish a specific color pair, the color presented by the object can be recognized by color blind patients under an appropriate spectrum, but the appropriate spectrum is not currently available Methods

Abstract

The present application relates to a color-blindness-oriented illumination spectrum acquisition method, device, and equipment. The method includes: first acquiring the surface reflectance of a target object; Set the special illumination tristimulus value under the illumination spectrum; then use the preset evaluation function to evaluate the special illumination tristimulus value to obtain the evaluation result; when the evaluation result satisfies the preset condition, the preset lighting The spectrum output is the target spectrum; when the evaluation result does not satisfy the preset condition, update the preset lighting spectrum. Based on this, the evaluation function can be used to obtain the target spectrum satisfying the preset conditions.

Description

technical field [0001] The present application relates to the technical field of lighting spectrum, and in particular to a method, device and equipment for acquiring lighting spectrum for color blindness. Background technique [0002] Congenital color vision disorder, commonly known as color blindness, means that people with color blindness cannot distinguish colors or certain colors in the natural spectrum. Since the color of an object depends on the reflectance and illuminance of the object, and color blindness is just unable to distinguish a specific color pair, the color presented by the object can be recognized by color blind patients under an appropriate spectrum, but the appropriate spectrum is not currently available Methods. Contents of the invention [0003] In order to overcome the problems existing in the related technologies at least to a certain extent, the present application provides a method, device and equipment for acquiring an illumination spectrum for...
