IMAGE TRANSFORMATION APPARATUS AND IMAGE TRANSFORMATION METHOD

摘要

Provided is an image transformation apparatus (10) wherein an image captured by a vehicle-mounted camera (2) is transformed to a bird's eye view image, which is then displayed on a vehicle-mounted monitor (3). The image transformation apparatus comprises: an image transformation unit (12) that transforms the captured image to the bird's eye view image in accordance with the position and angle of the vehicle-mounted camera; a feature point extraction unit (15) that extracts a plurality of feature points from the bird's eye view image or from the captured image; a calculation determination unit (16) that determines, on the basis of the distribution of the plurality of feature points extracted from the bird's eye view image or from the captured image, whether to calculate the position and angle of the vehicle-mounted camera; and a calculation unit (17) that calculates the position and angle of the vehicle-mounted camera on the basis of the plurality of feature points if the calculation determination unit determines that the position and angle of the vehicle-mounted camera are to be calculated.
