Abstract
Disclosed is a portable 3-dimensional (3D) document scanning device and method. The portable 3D document scanning device includes a projector projecting light of a predetermined pattern onto a document, a 3D scanning camera capturing a pattern of the light projected onto the document and the document, and a control unit estimating a size of the captured document based on image data of the captured document, estimating a shape of the captured document based on the pattern of the projected light and the captured pattern of the light, and correcting the image data of the captured document based on the estimated size and the estimated shape.
Claims11
A portable 3-dimensional (3D) document scanning device, the device comprising:
- a projector configured to project light of a predetermined pattern onto a document;
- a 3D scanning camera configured to capture a pattern of the light projected onto the document and the document;
- and
- a control unit, wherein the control unit is configured to:
- estimate a size of the captured document based on image data of the captured document;
- estimate a shape of the captured document based on the pattern of the projected light and the captured pattern of the light;
- and
- correct the image data of the captured document based on the estimated size and the estimated shape.
A portable 3D document scanning method, the method comprising:
- projecting light of a predetermined pattern onto a document by using a projector;
- capturing a pattern of the light projected onto the document and the document by using a 3D scanning camera;
- estimating a size of the captured document based on image data of the captured document and estimating a shape of the captured document based on the pattern of the projected light and the captured pattern of the light;
- and
- correcting the image data of the captured document based on the estimated size and the estimated shape.
