Object shape detection device, vehicle equipped with it, and object shape detection method

摘要

Provided is an object shape detecting device capable of detecting the shape of a convex portion or a concave portion on the surface of an object. The reflection intensity of the radio wave at the convex portion 4a of the detection object 4 has a small difference between the horizontally polarized component and the vertically polarized component due to polarization, and the reflected intensity of the radio wave at the concave portion 4b is the horizontally polarized component and the vertically polarized component. A large difference due to polarization appears. The object shape determination unit 36 detects the shapes of the convex portion 4a and the concave portion 4b in the detection object 4 based on the comparison result of the horizontal polarization component and the vertical polarization component of the reflected wave by the reflection intensity comparison unit 35. .. The object position determination unit 37 measures the distances to the convex portion 4a and the concave portion 4b of the detected object 4 detected by the object shape determining unit 36, and detects the positions of the convex portion 4a and the concave portion 4b of the detected object 4.
