Abstract
A method and apparatus for detecting an object on a road around a vehicle. The method includes referring to three-dimensional geographical data, calculating a distance DA to a detecting object BLD in a 360 degree range, defining an area for the detecting target by the distance DA, measuring a distance DB to the object BLD and an object OBL in the 360 degree range when the vehicle travels, determining that the object is present on a road around the vehicle when DB<DA, and outputting the determination result.
Claims11
An apparatus for detecting an object around a vehicle comprising:
- a vehicle positioning device operable to detect a vehicle position;
- a database, the database including three-dimensional geographical data;
- an area defining device operable to utilize the three-dimensional geographical data to define an area for detecting a target;
- object detecting device operable to measure a distance between a vehicle position and an object and determine whether the object is within the area defined by the area defining unit;
- an output device operable to identify if the object detecting device has detected an object within the area,
- wherein the object detecting device compares the distance between the vehicle position and the object with the distance between the vehicle position and a building.
An apparatus for detecting an object around a vehicle comprising:
- a vehicle positioning device operable to detect a vehicle position;
- a database, the database including three-dimensional geographical data;
- an area defining device operable to utilize the three-dimensional geographical data to define an area for detecting a target, wherein the defined area is a portion of a total detectable area around the vehicle;
- an object detecting device operable to measure a distance between a vehicle position and an object and determine whether the object is within the area defined by the area defining unit;
- an output device operable to identify if the object detecting device has detected an object within the area,
- wherein the area defining device calculates the area for detecting a target by calculating a distance between the position of the vehicle and a building that is greater than or equal to a predetermined height.
