Digital image capturing device and color difference correction method and device of screen

Abstract

The invention provides a digital image capturing device and a color difference correction method and device for a screen. The method comprises the following steps: providing a to-be-corrected digitalimage capturing device and a to-be-corrected display screen; providing a wavelength-adjustable single-wavelength standard spectrum light source; performing standard image capture; generating an imagecapturing chromaticity correction parameter; completing correction of the digital image capturing device; inputting a standard gray scale signal; correcting the front screen to capture an image; generating a screen chromaticity correction parameter; and completing screen correction. A color characteristic configuration file is built in the standard imaging screen device, and the system correctionparameters generated by the method are recorded in the color characteristic configuration file. And the standard digital image capturing device comprises the image capturing chromaticity correction parameters generated by the method. By means of the implementation of the invention, the full-flow chromatic aberration correction from the digital image capture device and the screen can be quickly andeffectively completed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for correcting chromatic aberration of a digital imaging device and a screen and a device thereof. Background technique [0002] The oral cavity includes teeth, lips, tongue and other parts, and is the first stop for the human body to digest food; the main organs in the oral cavity include teeth, tongue, mucous membrane and salivary glands, etc. The part of the teeth exposed in the oral cavity is the crown, while the root of the tooth is not exposed part. Teeth can be divided into three parts from the inside out: enamel, dentin and pulp. [0003] When the dentist finds that the tooth is damaged and needs to be replaced, then it is necessary to replace the damaged tooth with dentures; The dental laboratory includes: 1. Substrate production → 2. Digital scanning → 3. Digital design → 4. Design completion → 5. Digital precision processing → 6. Zirconia back treat...

AI Technical Summary

Problems solved by technology

[0004] When manufacturing dentures, because the color of dentures is related to the consistency or coordination with the color of other teeth, it has a very critical impact on the overall aesthetics of the oral cavity. The information on the consistency of denture color will depend on the imaging device and screen used by the dentist; however, if the imaging device and screen that have not been corrected for color difference are used, the tooth color information will be more accurate due to the error of the equipment. inconsistent
