MODEL GENERATION METHOD, MODEL GENERATION APPARATUS, NON-TRANSITORY STORAGE MEDIUM, MOBILE OBJECT POSTURE ESTIMATION METHOD, AND MOBILE OBJECT POSTURE ESTIMATION APPARATUS

A model generation method includes specifying image coordinates that fall within a two-dimensional image obtained by capturing at least a mobile object and that correspond to at least one point among vertexes of a rectangular shape formed when an outer shape of the mobile object viewed from above is projected on a road, as a key point of the mobile object, and creating the two-dimensional image, to which information on the key point is added, as training data, and generating a machine learning model that outputs the key point from a two-dimensional image obtained by capturing at least a mobile object, by performing machine learning using the training data.
