Abstract
A method of analyzing the surroundings of a vehicle, comprising the steps of: gathering data regarding objects in the vicinity of the vehicle; analyzing the data to determine regions of empty space around the vehicle; creating one or more signatures representing at least some of the regions of empty space; and storing the signatures for later retrieval.
Claims23
A method of analyzing the surroundings of a vehicle, comprising the steps of:
- gathering data regarding one or more locations of objects in the vicinity of the vehicle;
- analyzing the data to determine regions of empty space around the vehicle;
- creating one or more signatures by creating one or more primitives describing at least some of the regions of empty space by expanding a shape around a position until a perimeter of the shape reaches at least one of the one or more locations of the objects and by defining one or more further shapes and expanding the one or more further shapes in directions that avoid the at least one of the one or more locations of the objects;
- and
- storing the signatures for later retrieval and ignoring all information relating to the one or more locations of the objects for which data have been gathered.
2 more elements
A vehicle comprising:
- an object detection arrangement configured to change a scanning area relative to the vehicle in response to a detection of an object;
- a positioning arrangement;
- a processing arrangement operable to carry out the steps of:
- gathering data from the object detection arrangement regarding one or more locations of objects in the vicinity of the vehicle;
- analyzing the data to determine regions of empty space around the vehicle;
- directing the object detection arrangement upon detection of the object to change the scanning area in a direction that avoids the object;
- creating one or more signatures by creating one or more primitives describing at least some of the regions of empty space;
- ignoring all information relating to the one or more locations of the objects for which the data have been gathered;
- and
- storing the signatures for later retrieval;
- and
- a memory to store the signatures.
