Abstract
Disclosed are a scan guide providing method and an image processing device therefor. A scan guide providing method according to an embodiment comprises the steps of: displaying, on a scan screen, a guide scan path for providing a scanning strategy of an intraoral scanner; tracking a user scan path actually scanned, along the guide scan path, by the intraoral scanner; and displaying the tracked user scan path together with the guide scan path.
Claims19
A scan guide providing method comprising:
- displaying, on a scan screen, a guide scan path providing a scanning strategy of an intraoral scanner;
- tracking a user scan path scanned through the intraoral scanner along the guide scan path;
- and
- displaying the tracked user scan path together with the guide scan path,
- wherein the tracking of the user scan path comprises:
- creating a depth image by reconstructing a two-dimensional (2D) image acquired through scanning by the intraoral scanner;
- connecting central points or main points of objects constituting the depth image;
- and
- generating the user scan path by detecting intersection points from the central points or main points on the objects to a position on a surface of a three-dimensional (3D) object and connecting the detected intersection points.

An image processing device comprising:
- a data acquisition unit configured to acquire, from an intraoral scanner, image data acquired by scanning an inside of a user's mouth or an intraoral model;
- an output unit configured to display the image data acquired from the intraoral scanner and a guide scan path providing a scanning strategy of the intraoral scanner;
- and
- a control unit configured to receive and image-process the image data acquired by the data acquisition unit and providing the guide scan path to the output unit,
- wherein the control unit configures a screen by tracking a user scan path scanned through the intraoral scanner along the guide scan path and matching the tracked user scan path to the guide scan path, and
- the output unit displays the user scan path on the screen together with the guide scan path, and
- wherein the control unit creates a depth image by reconstructing a two-dimensional (2D) image acquired through scanning by the intraoral scanner, connects central points or main points on objects constituting the depth image, and generates the user scan path by detecting intersection points from the central points or main points on the objects to a position on a surface of a three-dimensional (3D) object and connecting the detected intersection points.
