ABSTRACT:
A reflection-point estimation section constituting an object detection apparatus first calculates a rotational correction angle for each estimated reflection point Pnby using the following equation, using the fact that the ratio of the amount of change in a detected distance dnto a movement amount Inof a sonar is nearly equal to a tangent with respect to the direction normal to the surface of an object:in-line-formulae description="In-line Formulae" end="lead"?Rotational correction angleφ=atan {(dn+1−dn)/In}in-line-formulae description="In-line Formulae" end="tail"?in which n is a natural number. Subsequently, the reflection-point estimation section obtains estimated reflection points Pn′ after correction, by rotating each estimated reflection point Pnbased on the calculation result.
