Stereoscopy is based on a pair of images being reconciled by a single processing unit.
In human beings, each of the two eyes supplies one of the pair of images, which are
reconciled by the brain to create a single stereoscopic 3D image. The different viewing
angles therefore allow spatial vision and therefore an assignment of distances.
This principle can be simulated by technology. In a driver assistance system, it is used
to determine how far away a vehicle is from objects in its path. The sensor head delivers
the 3D image, which is then compared by the evaluation unit to identify hazards. During
processing, 3D data is assigned to the scene in order to facilitate checking against a
virtual spatial zone (alarm zone).
The detection performance depends on:
• The distance to a flat boundary surface, such as the ground, a ceiling, a wall, etc.
• The mounting angle in relation to the ground
• The ambient conditions
The maximum detection range is preset to 7 m. This value may differ or be physically
delimited due to environmental influences or mounting parameters.
