What lenses to use for a multistereoscopic solution (to 3d pointcloud)

[vasa.dhananjay]

Where should I start when it comes to selecting enses (and cameras) for a multistereo solution? I'm looking to observe a 200'x40'x40'x volume. There will have to be multiple cameras due to occlusion, but I imagine even different lenses or at least variable focal lengths to generate accurate point clouds.

Not sure what my budget is so more important is knowing what characteristics I should be looking for or how to determine them.

Hi vasa.dhananjay,

I would recommend contacting a Graftek Imaging Inc. They specialize in Vision Solutions and I believe will be very helpful in assisting you with lens selection. Below I’ve provided a link to their online Lens Selector along with a NI KnowledgeBase which may be helpful as well.

Also, I wanted to provide you with some helpful information on Stereo Vision.

for making code easy you have to use camera with still focal lens otherwise any time you change the focal distance you have to recalibrate your photos Also take look at lens that are famous to telecentric lens
