Stereoscopic 3D

Hello!

 

Anyone tried to make from two camera images, a stereoscopic 3D image, which you can see with red-cyan glasses?

I would appreciate any help about it. I mainly need an example.

Thank you!

HI gbbalint,

 

What exactly are you trying to do? Why do you want to see the image via red-cyan glasses?


Typically, red-cyan glasses give the "feeling"of 3D by filtering polarized light. Basically one side of the glasses blocks a polarized light and let's the other one passed and viceversa. And the eyes capture the light and processed in the brain gives the 3D "feeling".

LabVIEW and 3D vision is used in research mainly to get a feeling a 3D, from computer point of view. Basically we need an extra information to be able to process and take decisions (from computer point of view), typically is a 2D image and the 3rd information needed is the colour.

 

Common application where there is used 3D:

1. Profilometer - surface visualisation and roughness analysis to use in laser-processed surface characterization

2. 3D Medical Image system  

 

Coming back to your question, in order to achieve to see 3D through red-cyan glasses you have to find a way to generate polarized light first.

 

A nice demo that shows how to build a 3D display system can be found here. Basically it is using 4 cameras to acquire data and using a video projector and a pyramid, can project the 3D model.

 

Hope that helps you continuing with your project.


Best regards,

IonR.

Hello!

 

I have a project to compare LabVIEW 3D solutions with another programs. I could make stereoscopic like pictures from two kamera images, and I didn't need any special equipment for that. Now it's the turn for LabVIEW, that's why I'm interested in it.

Hi,

 

What do you mean by stereoscopic pictures? Could you post them?

In regards of technologies for 3D and LabVIEW, I believe that the links sent above should help you providing a very good overview.


Best regards,

IonR
