Abstract:
A method and apparatus for vehicle recognition are provided, which are combined with a radar apparatus scanning a detection area with electromagnetic waves. Data derived from reflection waves are outputted from the radar apparatus to the vehicle recognizing apparatus to detect a vehicle in the detection area. The vehicle recognizing apparatus is provided with a processor performing a process for the recognition on calculation of the received data for the recognition of vehicles. In the process, weak-refection directions providing weak-reflection points on a vehicle are determined which are defined as radiation directions of the electromagnetic waves in which the reflection waves have intensities lower than a threshold. A common reflection point group defined as a group of reflection points belonging to the same vehicle is supplemented with the weak-reflection points for completing the common reflection point group.

Claim (Index 9):
A method of recognizing a vehicle, the method being cooperated with a radar apparatus which radiates electromagnetic waves to a detection area at intervals for scanning the detection area, receiving reflection waves at the intervals, and outputting data based on the received reflection waves, the electromagnetic waves having a directivity, the vehicle recognizing method comprising:\n processing the received data by calculation based on a predetermined calculation algorithm previously stored in a memory device, wherein the processing provides via the calculation: a stationary object determining step determining, based on the reflection waves, a distance from the radar apparatus to a stationary object in all radiation directions of the electromagnetic waves scanned; a reflection point determining step determining, based on the distances determined in all the radiation directions and the reflation waves in all the radiation directions, positions of reflection points which reflect the electromagnetic waves, the positions being closer to the radar apparatus than the stationary object is; a reflection-point group determining step determining, of the reflection points determined, a common reflection point group defined as a group of reflection points belonging to a common vehicle; a weak-refection determining step determining weak-refection directions which are defined as radiation directions of the electromagnetic waves in which the reflection waves have intensities lower than a threshold; a continuous-reflection detection determining step determining, of the determined weak-reflection directions, one or more continuous reflection directions which are continuous in a scan direction, at the intervals, to the radiation directions of the electromagnetic waves to the common reflection point group; and a point group generating step, based on an assumption that the vehicle has a rectangular contour in a plane including the all the radiation directions of the electromagnetic waves and the determined common reflection point group, supplementing the common reflection point group with weak-reflection points estimated as belonging to the common vehicle.
