Abstract
An image augmentation apparatus () acquires an original training dataset (). The original training dataset () includes a ground-view image () and an original aerial-view image (). The image augmentation apparatus () performs an image augmentation including a cropping process and a rotation process on the original aerial-view image () to generate an augmented aerial-view image (). In the cropping process, a target region with a circle shape or a regular polygon shape is cropped from the original aerial-view image (). In the rotation process, the original aerial-view image () is rotated. An angle of the rotation is a multiple of a center angle of the target region when the target region has a regular polygon shape. The image augmentation apparatus () outputs an augmented training dataset () including the ground-view image () and the augmented aerial-view image ().
