LEARNING METHOD, LEARNING DEVICE, MOBILE OBJECT CONTROL DEVICE, MOBILE OBJECT CONTROL METHOD, AND STORAGE MEDIUM

A learning method includes steps of associating, with an extended area in a bird's-eye view image, an annotation indicating that the extended area is a three-dimensional object; and generating, based on training data in which a bird's-eye view image is associated with an annotated bird's-eye view image obtained by assigning an annotation to a three-dimensional object in the bird's-eye view image, a trained model by learning parameters of a machine learning model so that the trained model receives input of a bird's-eye view image to output a three-dimensional object in the bird's-eye view image.
