Problems solved by technology

However, this analysis method that requires multiple photographs during the entire treatment period is cumbersome, and since the same area on the same subject's teeth must be analyzed multiple times in this method, complex programming algorithms are required to accurately select "Registration unit", otherwise it is difficult to make effective comparisons

Embodiment Construction

[0037] figure 1 A schematic configuration diagram of a system for taking pictures of tooth tissues according to an embodiment of the present disclosure is shown. As shown in the figure, a camera used as an image acquisition device is installed on a bracket to take pictures of the oral cavity of the subject to obtain oral images. The fine-tuning of the camera position can be realized through auxiliary means, for example, the elevation angle, height position, front-back distance of the camera can be adjusted, or it can be shaken left and right. The installation part at the bottom of the camera can be arranged on the bracket in cooperation with the slider structure and the fixing bolt, so that the camera can move forward and backward along the bracket.

[0038] In order to achieve a better shooting effect, an appropriate light source can be set in front of the measured object to illuminate the shooting position. Such as figure 1 As shown, the light source is also arranged on t...

Abstract

The invention provides a method and device for analyzing an oral tissue and especially analyzing the tooth tissue of a tested target as well as a dental analysis system. An oral image of the tested target is processed, for example a color value of the oral image is adjusted, so that a to-be-analyzed oral tissue area, for example, all or partial teeth (such as at least one tooth or at least two teeth) in the oral cavity is highlighted. Therefore, the highlighted to-be-analyzed oral tissue area can be selected so as to be analyzed. By adopting the method and system, the health situation of the teeth can be conveniently and rapidly judged, the tested target does not need to be photographed for multiple times, and a complicated programming algorithm is not needed.

Description

technical field [0001] The present disclosure generally relates to a method and device for analyzing oral tissue, and more specifically, some embodiments relate to a method and device for analyzing tooth tissue of a measured object by taking pictures, and a dental analysis system. Background technique [0002] At present, in order to visually analyze people's dental health status (such as tooth stains, dental plaque, whiteness, etc.), a digital camera system and a supporting software processing program have been developed. For example, P&G's invention patent application WO2009091409 discloses a method and device for image analysis of oral hard tissue, which analyzes the color values ​​of selected regions (registration units) on tooth surface images , so as to compare the health status of the relevant teeth before and after treatment. In this technical solution, an image of oral hard tissue is first displayed on a display device, and then one or more pixel points in the imag...
