<p><P>PROBLEM TO BE SOLVED: To provide an object detecting device capable of discriminating non-uniform figure objects, such as a variety of fogs and steams, simply and surely. <P>SOLUTION: The object detecting device for detecting objects in the circumference of a vehicle, by using reflected waves of transmitted electromagnetic waves to circumference of the vehicle, computes the distance to the reflection point from transmission timing and receiving timing of the electromagnetic waves and the electromagnetic waves computes the real space vector of the reflection point on the object from irradiated direction of the electromagnetic waves (STEP40). A plurality of reflection points in which distance of reflection point is within a predetermined range is classified as one reflection point group, and the extent on the real space, in which the reflection point group concerned exists, is considered as one segment (STEP50). Finally, in a first segment segmented as a first reflection point group, when the first reflection points where a second reflection point other than the first reflection points is also produced on a scanning line of the electromagnetic waves passing through the first segment exist higher than a predetermined percentage, the objects consisting of the first segment concerned are discriminated as being nonuniform figure objects, such as, fog and steam (STEP60). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
