Abstract
In an alignment state indicating apparatus and method according to the present invention, scanning is performed by a scanner, raw data is formed through light incident into the scanner, 3D data is formed through the raw data, and alignment is performed. When it is determined that such an alignment process of 3D data is not performed normally, the alignment state indicating apparatus and method according to the present invention provide visual feedback to a user on an alignment error in the form of a specific pattern, thereby allowing the user to quickly recognize whether to perform the alignment. Accordingly, the alignment state indicating apparatus and method have the advantage of improving the reliability of scanning by allowing the user to scan an object closely.
Claims17
An alignment state indicating apparatus comprising:
- a case having an opening formed thereon and configured to be open so that an object in the form of light enters into the case;
- a light radiation unit disposed inside the case and configured to emit light in a first form having a predetermined rule through the opening;
- an imaging unit formed on one side of the light radiation unit and configured to obtain raw data by receiving incident light through the opening of the case;
- and
- a controller configured to determine whether an alignment error occurs by performing data alignment between 3D data generated through imaging by the imaging unit,
- wherein the controller is configured to perform visual feedback of an alignment state by controlling the light emitted from the light radiation unit to be changed to a second form that is different from the first form when the alignment error occurs,
- wherein the light radiation unit comprises a light source unit configured to generate the light, and a DMP chip having a plurality of micro-mirrors arranged in the form of an array.
An alignment state indicating method comprising:
- a light radiation step of emitting light in a first form having a predetermined rule, to scan an object through a scanner, by a light radiation unit built in the scanner;
- a scanning step of scanning the object through the scanner;
- a raw data obtaining step of obtaining raw data by an imaging unit formed on an inside of the scanner through a light incident to an inside of the scanner in the scanning step;
- an alignment step of performing data connection and alignment between 3D data;
- an alignment checking step of determining whether an alignment error occurs in the alignment step between the 3D data;
- and
- a feedback step of indicating an alignment error state by emitting light in a second form that is different from the light in the first form by the light radiation unit when the alignment error occurs in the alignment checking step,
- wherein the light radiation unit comprises a light source unit configured to generate the light, and a DMP chip having a plurality of micro-mirrors arranged in the form of an array.
