 Dear Elpham,

There are many other issues that need to be considered when you select configuration of the stereo camera
What type of objects you need to measure, their angular size
What resolution do you need - angular and in distance
What software are you going to use - what kinds of lens distortions it can tolerate/compensate?
Does this software use color or monochrome images?
And many more

I would also recommend trying more than just 2 sensors - our experience indicates that it is much easier to avoid ambiguity before doing any feature extraction by just combining 3 or 4 images instead of 2.

Dear Andrey,
Thank you for your kindly answering and suggestion. I think NC353 camera with 5MPix resolution is enough for me(because of high speed of algorithm). in my project i need to see the depth of 50 meters(max).In your opinion is it possible? And the parameters of  focal length and angle of view in what range should be? Elham
