A Scanner for Computing Box Dimensions in Real Time

Welcome to Box Dimensions Project Home Page. Here we present a completely automatic approach for real-time computation of boxes dimensions from single perspective projection images. Given a picture of a box, acquired with a camera whose intrinsic parameters are known, the dimensions of the box are computed from the extracted box silhouette and the projection of two parallel laser beams on one of its visible faces. We demonstrate the proposed approach by building a prototype of a scanner for computing box dimensions and using it to automatically compute the dimensions of several boxes.

The main contributions of this research include:

• An algorithm for computing the dimensions of boxes in a completely automatic way in real-time;
• An algorithm for extracting box silhouettes in the presence of partial occlusion of the box edges;
• A statistical model for detecting background pixels under different lighting conditions, for use with a moving camera; and
• An efficient voting scheme for identifying approximately collinear line segments using a Hough Transform.

This project is being developed Leandro A. F. Fernandes and Manuel Menezes de Oliveira Neto, with controbutions of Roberto da Silva.
