What is stereo vision system?

Stereo vision systems are computer vision implementations that use stereoscopic ranging techniques to estimate a 3D model of a scene. Stereo vision employs triangulation, a popular ranging technique, to compute the depth from 2D images.

What is active stereo vision?

The active stereo vision is a form of stereo vision which actively employs a light such as a laser or a structured light to simplify the stereo matching problem. Active stereo is useful in regions where there is a lack of light and/or texture.

How does a stereoscopic vision sensor work?

Stereovision techniques use two cameras to see the same object. The two cameras are separated by a baseline, the distance for which is assumed to be known accurately. The two cameras simultaneously capture two images. The two images are analyzed to note the differences between the images.

What is stereo vision used for?

Stereo vision is an imaging technique that can provide full field of view 3D measurements in an unstructured and dynamic environment. The foundation of stereo vision is similar to 3D perception in human vision and is based on triangulation of rays from multiple viewpoints.

What is the main difference between mono and stereo visions?

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 active stereo?

Active stereo emerges as an alternative approach to the traditional use of two cameras. In an active stereo vision system, one of the cameras is replaced with a projector or a laser unit, which projects onto the object of interest a sheet of light at a time (or multiple sheets of light simultaneously) (Fig. 10).

How does a stereoscopic camera work?

A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. If the image is edited so that each eye sees a different image, then the image will appear to be 3D.

How do you do stereoscopic vision?

A stereoscopic image pair taken with two cameras. Right eye view on the left, left eye view on the right. To view, cross your eyes, until the two squares align, and focus on the middle image.

Can any camera be used for facial recognition?

Facial recognition is still a rare feature in home security cameras. And not all the cameras boasting the technology actually have it. There are a handful of smart cameras on the market with true facial recognition software — from Honeywell, Nest, Netatmo, Tend Secure, Wisenet — but more are on the horizon.

What are the advantages of stereo vision?

Stereopsis appears to be a compelling depth cue except when in conflict with motion or occlusion. It has certain advantages: Surface properties such as luster, scintillation, and sheen are difference in luminance and color between the left and right retinal images, and cannot be seen in single image.
