Obstacle detection using 2 cameras : application for rear vision, by NEXYAD (ObstaNex BiCam V1.0) :

NEXYAD is proud to annouce ObstaNex BiCam : 2 cameras for obstacle detection. This is not stereovision : this is two
monovision obatacle detection (using OnstaNex V2.1) plus a data fusion algorithm that makes it 3D.

Then even is one camera is off, then the system still can detect objects (precision is lower, but system is still operational).

Here is an example of application to REAR VISION (for trucks, vans, ...) :
