Abstract
An axial misalignment estimation apparatus estimates an axial misalignment angle of a radar apparatus mounted in a moving body. The estimation apparatus repeatedly acquires, for each reflection point detected by the radar apparatus, reflection point information including at least a relative speed and an orientation angle. The estimation apparatus acquires a speed of the moving body and extracts a stationary reflection point estimated to be a stationary object from the reflection points based on the speed of the moving body. The estimation apparatus selects, for each divided region, the stationary reflection point included in the divided region such that a predetermined condition is met. The divided region is a detection region of the radar apparatus that is divided into a plurality of parts in at least either of a horizontal direction and a vertical direction. The estimation apparatus determines the axial misalignment angle using the stationary reflection point selected.
