Method of triangulation with laser-diodes and a mono-camera for determining distance in stop-and-go applications for motor vehicles

摘要

Method for measuring the distance to objects in the area (7) in front of a motor vehicle using a mono-camera (8), primarily intended for a lane departure warning or night-vision system, and an additional four laser diodes (LD1-4). These are used as active triangulation sensors and permit a simple distance calculation. Provision of downstream grey-value image processing means that advanced ACC-functions (adaptive cruise control) can be provided.
