[0049] figure 1 is a block diagram of the dental image matching device according to the first embodiment of the present invention.

[0050] Such as figure 1 As shown, the tooth image matching device 100 of the first embodiment of the present invention may include: a maximum contour detection unit 110 , an inscribed circle detection unit 120 , an inscribed ball detection unit 130 and an image matching unit 140 .

[0051] The tooth image matching apparatus 100 of the first embodiment of the present invention matches first tooth image data and second tooth image data.

[0052] Here, the first dental image data and the second dental image data are image data that have mutually different coordinate systems or resolutions because they are captured by different image capture devices or at different time points, respectively. It may be one of CT (Computed Tomography) image data, oral scan (Oral Scan) image data, and magnetic resonance image (Magnetic Resonance Image; MRI) data.

[0105] Figure 12 is a block diagram of a dental image matching device according to a second embodiment of the present invention.

[0106] Such as Figure 12 As shown, the tooth image matching device 200 of the second embodiment of the present invention may include: a maximum contour detection unit 210 , a center point detection unit 220 and an image matching unit 240 .

[0107] The tooth image matching apparatus 200 of the second embodiment of the present invention matches first tooth image data and second tooth image data.

[0108] Here, the first dental image data and the second dental image data are image data that have mutually different coordinate systems or resolutions because they are captured by different image capture devices or at different time points, respectively. It may be one of CT (Computed Tomography) image data, oral scan (Oral Scan) image data, and magnetic resonance image (Magnetic Resonance Image; MRI) data.

Abstract

The present invention provides a dental image registration device comprising: an outermost boundary detection unit for detecting, from first teeth image data, a first outermost boundary region which is the outermost boundary region of dentition, and detecting, from second teeth image data, a second outermost boundary region which is the outermost boundary region of the dentition; and an image registration unit which registers the first and second teeth image data on the basis of a first inscribed circle inscribed within the first outermost boundary region and a second inscribed circle inscribed within the second outermost boundary region, or registers the first and second teeth image data on the basis of a first central point of the first outermost boundary region and a second central point of the second outermost boundary region.

Description

technical field [0001] The present invention relates to a dental image matching device and method, in particular, to a dental image matching device and method capable of matching dental images with high accuracy and high speed. Background technique [0002] When shooting a scene or object from different times or angles in computer vision, images with different coordinate systems will be obtained. Image matching refers to the process of warping these mutually different images to be displayed in one coordinate system. [0003] Through such image matching, it is possible to confirm the correspondence between images obtained by different measurement methods. [0004] In the dental surgical guide software, before entering the dental implant planning step, an image matching process between CT (Computed Tomography) image data and oral scan (Oral Scan) image data is usually performed. [0005] The image matched by this image matching process is the basis of dental implant planning...
