Discussion Overview

The discussion revolves around the challenges of performing 3D tomographic reconstruction using images from cameras positioned at three different locations, specifically utilizing MATLAB for this task. Participants share resources and suggestions to assist someone who is struggling with the technical aspects of the project.

Discussion Character

  • Technical explanation
  • Homework-related
  • Experimental/applied

Main Points Raised

  • One participant expresses difficulty in using MATLAB for 3D reconstruction and seeks advice or code to help with the task.
  • Another participant provides a link to a Stack Overflow post that may contain relevant information for creating a 3D model in MATLAB.
  • A third participant reiterates the previous suggestion and acknowledges the presence of knowledgeable individuals who might assist.
  • Another participant shares a resource that discusses reconstructing 3D images from 2D cameras and suggests looking for related literature and online resources to understand the underlying mathematics.
  • One participant proposes the idea of creating an interactive science demonstration to help visualize the principles of tomography, indicating a potential application of the discussed concepts.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of sharing resources and links to assist with the MATLAB implementation, but there is no consensus on specific methods or solutions for the reconstruction task itself.

Contextual Notes

Limitations include the participant's lack of familiarity with MATLAB, which may affect their ability to implement the suggested resources effectively. Additionally, the discussion does not delve into the mathematical details or assumptions underlying the reconstruction process.

Who May Find This Useful

This discussion may be useful for students or researchers interested in 3D imaging, tomographic reconstruction, or those seeking guidance on using MATLAB for similar projects.

So to get a better edge on our experiment my professor asked if I could take the pictures from cameras which are mounted at three different locations and use MATLAB to create a 3d picture. I have made no progress as I don't really even know MATLAB well. Is there any code or advice one can give?

A nice short very applied chapter on reconstructing 3d images from 3 2d cameras.

http://www.dspguide.com/ch25/5.htm

Looking at amazon.com for that title turns up that book and what looks like lots of other closely related books that look fascinating.

Or Google

tomography fourier

and look for the simplest mathematica description of what is behind this. Then you can consider Matlab implementation.

I've thought for a long time that it would be possible to build hands-on interactive science museum demo that used light beams and semitransparent objects placed on a rotating table to let people really understand what was behind tomography. Someone should do that.
