Problems solved by technology
However, the processing software also has very high requirements for the image color quality of the digital microscope imaging system. If the image color quality is not good, it will not only affect the visual effect, but also have a great negative impact on the post-processing and analysis of the image. Color Correction of Digital Transmission Microscope Images
Most of the current color correction solutions use the white balance algorithm, but the white balance algorithm is only a rough color correction method, and cannot achieve accurate color correction of the digital microscope imaging system

Embodiment Construction
[0029] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.
[0030] Taking a biological microscope as an example, the method of color correction of color digital transmission microscope based on micro transmission color card is described.
[0031] The method for correcting the color of a color digital transmission microscope based on a miniature transmission color card in this embodiment specifically includes the following steps:
[0032] (1) Turn on the illumination light source of the color digital transmission microscope, warm up for a period of time, place the micro transmission color card under the eyepiece of the stage, take a picture of the micro transmission color card, and obtain the RGB values of all color blocks in the color card image, which are recorded as P is a matrix with 45 rows and 3 columns, in which 45 is the number of color blocks on the micro-transmission color card, 3 is the nu...

The invention discloses a color correction method for a color digital transmission microscope, which uses a miniature transmission color card to correct the color of a microscopic image collected by a color digital transmission microscope. Since the lighting source of a digital microscope is usually fixed, the digital camera under fixed conditions The chromaticity characterization is especially suitable for the color correction of digital microscopes. Therefore, the present invention uses the color blocks in the micro-transmission color card as training samples to establish the forward chromaticity characterization model of the color digital transmission microscope. Using this model, the shooting target can be achieved. Accurate color correction improves the color accuracy of the color digital transmission microscope, conforms to the color perception of the human eye, realizes the effect of what you see is what you get, significantly improves the recognition of the target object in the microscopic inspection, and realizes the accurate identification and positioning of the target object.
Description
technical field [0001] The invention relates to a microscope color correction method, in particular to a color digital transmission microscope color correction method. Background technique [0002] In the color digital imaging system, people put forward higher and higher requirements for the color quality of the image. The color formation of the digital microscope imaging system has its particularity. On the one hand, it must conform to the sensory characteristics of the human eye, and on the other hand, it must reflect the primary color of the object as realistically as possible. A large part of the existing color digital transmission microscopes are used in medical detection, and many pathological features are distinguished by the color changes of cells, which requires high color authenticity. Microscopic image processing software is an integral part of digital microscopic imaging system. It converts the data collected by the image sensor into color images consistent with...
