Why are two cameras mounted in paralle in stereo application?

Spacing the cameras further apart (Giant's vision) gives you a better sense of depth at great distances and loss of stereoscopic vision at close distances due to the object only being fully visible with one eye.

Which are the main advantages of stereoscopic cameras?

Stereo camera design minimizes occlusions. Occlusions can be a significant roadblock to achieving reliable and accurate feature measurement. If you can't see a portion of the feature, then your data may be incorrect. Stereo designs offer a greater chance to make accurate measurements from a single acquisition sequence.

What are stereo cameras used for?

This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging.

What is the difference between stereo camera and mono camera?

If we have a single camera sensor mounted and capturing video that needs to be processed and analyzed, that system is called a monocular (single- eyed) system, whereas a system with two cameras, separated from each other is called a stereo vision system.

What is a stereo camera setup?

A stereo camera is a type of camera with two or more image sensors. This allows the camera to simulate human binocular vision and therefore gives it the ability to perceive depth.
