Floor surface condition detection device, distance measuring device equipped with same, floor surface condition detection method, and floor surface condition detection program

Abstract

A control unit () is a device for detecting the condition of a floor surface (FL) on which a target () has been placed, and comprises a distance calculation unit () and a target detection unit (). The distance calculation unit () calculates information about the distance to the target () according to the amount of reflection of the light emitted from a lighting device () toward the target (). The target detection unit () detects the condition of a floor surface (FL) on which the target () has been placed, on the basis of the information about the distance acquired by the distance calculation unit ().
