Three-dimensional perception of environment
First Claim
1. Device for three-dimensional detection of the environment about a street vehicle, in particular for detection of parking spaces, comprised of a distance sensor, which produces a series of two dimensional distance profiles, a data processing unit and a storage unit, which preprocesses sequentially following distance profiles, stores and from a sequencing of a sequential amount of distance profiles produces a three dimensional image of the environment, and a means for determining the distance covered by the street vehicle between each individual produced distance profile.

Abstract
A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.

12. Process for three dimensional detection of the environment about a street vehicle, in particular for detection of parking spaces, wherein
by means of a distance sensor a two dimensional distance profile is produced by means of a data processing unit and a storage unit, sequential distance profiles are processed, stored and from a sequencing of a sequential amount of distance profiles a three dimensional image of the environment is produced, and via means the traversed path between each individual of the produced distance profiles is determined.
