[edit] The Bright project

[edit] Project overview

Bright (standing for Bright Reconstruction with light) is a project of low-price 3-D scanner, with a simple camera (a webcam) and a laser line. A rotating platform is used to rotate the object and thus to do a scan of the full shape of the object.

This page presents the project, and offers to download some instructions to build your own 3-D scanner. You can download the software and compile it to use it out-of-the-box, or you can use it as a start point for your own project of 3-D scanner. There is some documentation of the software if you just want to use it without looking at the maths behind.

The scientific report is also avalaible to get a better understanding of the algorithms and the technologies used by the software.

The project is Open Source and distributed under the GPl licence.

[edit] Camera calibration

The main part of the project was actually to calibrate the camera. The camera calibration software is now included in the MIMAS open-source Machine Vision library, and can be used to calibrate your camera if you don't have any other program to do it.

You can get more information about the calibration in the dedicated page.


[edit] Applications

Here are some example of applications

  • computer vision : 3-D tracking
  • medicine : 3-D scan of a body
  • entertainment : 3-D model creation for video games
  • art conservation : keep a digital copy of an art work
