Fog system

The fog system in the indoor test facility can be used to simulate realistic fog scenarios with realistic moisture fog. A reduction in visibility (Meteorological Optical Range) down to 10 meters also enables the reproducible simulation of extreme fog events.

In addition to static tests, dynamic sensor and driving tests can also be carried out on a fogged area of approx. 780 m² (65 x 12 m). The length of the fog area of 65 meters makes it possible to investigate the effects on the environmental sensors of vehicles even over long distances. As fog also forms under the rain system, combinations of rain and fog are also possible.

The test system can be combined with other test equipment, such as the indoor positioning system for accurate positioning and ground truth of static and dynamically moving objects. Various targets (EuroNCAP compliant) are also available.

Application examples

Reducing the visibility (MOR) for testing optical sensors
Reduction of camera contrasts
Reproduction of scattering and absorption effects on active sensors such as lidar and radar
