Embodiment

[0037] The invention provides a tooth imaging system based on a depth image, including:

[0038] The infrared ranging module is used to calculate the distance between the oral base surface and the imaging device, and obtain the reference point and distance data; the infrared ranging module uses infrared rays as the medium, and judges the distance between the oral base surface and the image collector through the infrared reflection time distance as a reference distance. The base surface of the oral cavity is the measurement point selected during infrared distance measurement. This point is generally at the center of the depth image and can be modified.

[0039] The depth imaging module is used to capture the internal state of the oral cavity and form a depth image; the depth image of the tooth is collected through the depth camera, which reflects the distance from each part of the diseased tooth in the oral cavity to the depth camera, and the distance is represented by the pixe...

Abstract

The invention discloses a tooth imaging system and method based on depth images, and relates to the technical field of medical imaging. The system comprises an infrared distance measurement module, adepth imaging module and an image processing module. The method comprises following steps: distance between a datum point in the oral cavity and an image collector is calibrated by infrared reflectiontime, and the datum point and distance data are obtained; states of teeth in the oral cavity are shot by a depth camera, and the depth images are obtained; and the depth images are processed into images capable of clearly showing tooth profiles, and the images are subjected to normalization processing according to the datum point and the distance data. The depth image technology is applied to oral cavity imaging, so that the internal condition of the oral cavity can be observed effectively, particularly, accurate image display can be performed for oral problems such as wisdom teeth and dentalcaries, and a doctor is assisted to effectively diagnose symptoms of the patient.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a tooth imaging system and imaging method based on depth images. Background technique [0002] Oral health is an important part of human health. Oral health can not only enable people to chew food fully, provide adequate nutrition for the body, but also avoid and reduce oral viral infection, diabetes, coronary heart disease, stomach disease, low birth weight of newborns, etc. occurrence of disease. With the development of society and the improvement of people's material living standards, more and more people pay attention to oral health problems. However, due to the particularity of the position of the oral cavity, especially the particularity of the arrangement of teeth in the human oral cavity, the routine dental disease inspection method is oral X-ray film. But its limitation is that on the one hand, the patient needs to judge the state of the teeth through oral imag...
