Contact detection apparatus, projector apparatus, electronic board apparatus, digital signage apparatus, projector system, and contact detection method

Abstract

A contact detection apparatus detects contact of a contactor and a contacted object. The contact detection apparatus includes an imager that acquires three-dimensional imaging information of the contactor and the contacted object, a setter that sets a contact target surface based on the three-dimensional imaging information of the contacted object from the imager, a candidate detector that converts the three-dimensional imaging information of the contactor from the imager into two-dimensional information and detects an end portion candidate of the contactor based on the two-dimensional information and the contact target surface, and a contact determiner that decides an end portion of the contactor and determines the contact of the contactor and the contacted object based on the three-dimensional imaging information of the end portion candidate and the contact target surface.
