Embodiment 1

[0023] As attached in the manual figure 1 As shown, in this embodiment, the specific tooth decay identification algorithm steps are as follows:

[0024] Step 1: Take a clear image of the oral cavity containing tooth decay, and import the cropped image of the oral cavity;

[0025] Step 2: Set the color, saturation and lightness of the image respectively: 0<h<180, 0<s<255, 46<v<255;

[0026] The third step: image analysis calculates the area that meets the parameters of the second step, and obtains a mask image with the same size as the original image;

[0027] Step 4: Merge the original image and the mask image, and obtain a total of 15863 pixels in the region containing only teeth;

[0028] Step 5: Test the proportion of black and brown pixels on the cropped tooth area: the number of dark and brown pixels is 1608, accounting for 10.13%, which exceeds 5% of the total tooth area, and the result is unqualified.

[0029] The present invention is applicable to equipment for mor...

Abstract

The invention discloses an oral cavity tooth decay recognition algorithm, and belongs to the technical field of tooth decay recognition algorithms. Comprising the following steps: 1, acquiring an oral cavity image containing decayed teeth, and importing a cut oral cavity area image; 2, reading the HSV of the image, and setting a required parameter as (0 lt; hlt; 180, 0 lt; slt; 255, 46 lt; vlt; vlt; 255) in the housing; 3, creating a mask with the same size as the original image; 4, merging the two groups of data of the original image and the mask, namely separating out the region where the teeth are located; and 5, independently analyzing the image pixels of the region where the teeth are located, if the ratio of black brown pixel points exceeds 5%, outputting that the teeth are unqualified, otherwise, outputting that the teeth are qualified. According to the algorithm, the complete tooth image in the oral cavity can be obtained only by dividing the image into the color, the saturation and the brightness, the calculation content is simple, large-scale network data calculation is not involved, and the accuracy of the obtained result is high.
