1. An apparatus for taking dimensions of a 3D object, comprising:
- an image input means for obtaining an object image having the 3D object;
an image processing means for detecting all edges within a region of interest of the 3D object based on the object image obtained in said image input means;
a feature extracting means for extracting line segments of the 3D object and features of the object from the line segments based on the edges detected in said image processing means; and
a dimensioning means for generating 3D models using the features of the 3D object and for taking the dimensions of the 3D object from the 3D models.

Abstract
The present invention relates to an apparatus and method for real-time automatically taking the length, width and height of a rectangular object that is moved on a conveyor belt. The method of taking the dimensions of a 3D object, the method comprising the steps of: a) obtaining an object image having the 3D object; b) detecting all edges within a region of interest of the 3D object; c) extracting line segments from the edges of the 3D object and then extracting features of the 3D object from the line segments; and d) generating 3D models based on the features of the 3D object and taking the dimensions of the 3D object from the 3D models.
