Title:
OBJECT DETECTION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2007026211
Kind Code:
A8
Abstract:
A reflection-point estimation section (41) constituting an object detection apparatus (10) first calculates a rotational correction angle for each estimated reflection point Pn by using the following equation, using the fact that the ratio of the amount of change in a detected distance dn to a movement amount In of a sonar (50) is nearly equal to a tangent with respect to the direction normal to the surface of an object: Rotational correction angle fn=atan{(dn+1-dn)/In} where n is a natural number. Subsequently, the reflection-point estimation section (41) obtains estimated reflection points Pn' after correction, by rotating each estimated reflection point Pn based on the calculation result.
