Description

Closed daylight illuminating lamp box

Technical Field

The utility model relates to an illumination lamp house technical field specifically is a closed sunlight illumination lamp house.

Background

In the fields of textile, printing, coating, paint, plastic and other related industrial production and manufacturing, it is important to evaluate the color quality of a product by quickly measuring the color of the product. Conventional color evaluation is mainly by visual or spectrophotometric methods. Among them, the visual evaluation method is limited by factors such as age, sex, and experience difference of the observer, and it is difficult for different evaluators to always maintain a uniform evaluation result. The spectrophotometer evaluation method can only evaluate a plane object with uniform color by a contact color measurement mode, and cannot evaluate the color of an irregular object or products such as liquid, powder and the like by color measurement. The inventors proposed to perform non-contact photogrammetry (photogrammetry, see reference 1) on the surface color of an object of an arbitrary shape by using a digital photography method, and then evaluate the measurement result.

For photo color measurement, a standard color card image needs to be shot firstly under the uniform illumination environment of daylight illumination, a color measurement model is obtained by using a relevant mathematical algorithm, then a digital image of an object is shot under the completely consistent illumination environment, and the color measurement model is used for calculating the color data of the object, so that the uniform and closed daylight illumination environment is important for photo color measurement. The common lighting lamp boxes in life are all direct-lighting type lighting of LED light sources, and the lighting in the photographing area is uneven. In addition, current lamp house is mostly open lighting conditions, and external light source can shine on the object with the lamp house light source jointly promptly to lead to the effect of shooing easily to receive the influence that external light changes, can't satisfy the strict lighting requirements of taking a picture the color measurement on the whole.
