Technical Support

ADAS Technology

ADAS 's core sensor is the camera. It can collect wide-angle images(road, pedestrians, vehicles, and other obstacles). Images captured by the cameras are analyzed by supporting software and the safety information then triggers a response.

Infrared Deflectometry

A technique that measures surface slopes by analyzing the specular reflection image of a target.  It has two advantages, high sensitivity and direct measurement of surface slopes.  It is suitable for all types of ramp angle identification.
