Document Type and Number:
WIPO Patent Application WO/2018/026186
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for extracting three-dimensional coordinates of an object by using a single camera, and a method therefor. The present invention relates to a liquid discharge apparatus that calculates three-dimensional coordinates of feature points located on an object mounted on a mounting means and discharges a liquid material on a target point of the object by using the calculated coordinates. The present invention relates to an apparatus for extracting three-dimensional coordinates of an object by using a single camera, and a method therefor, the apparatus comprising: a discharge means for discharging a liquid material; a moving means for moving the discharge means; an imaging means, provided on the discharge means, for imaging the object at a plurality of positions; a coordinates calculating unit for calculating coordinates of all the feature points by extracting a plurality of different feature points from the imaged screens of the imaging means, selecting two different imaged screens including the same feature points, and calculating the coordinates of the same feature points by using trigonometry; and a control unit for moving the moving means so as to discharge the liquid material at a target point of the object through the coordinates of the feature points and discharging the liquid material through the discharge means. In addition, according to the present invention, it is possible to provide an apparatus for extracting three-dimensional coordinates of an object by using a single camera, and a method therefor, in which an object is imaged at various positions through an imaging means provided on a discharge means, the coordinates of the feature points of the object are calculated through imaged screens, and a liquid material is discharged on a target point of the object through the calculated coordinates.
