Abstract
A three-dimensional shape measuring apparatus includes a fixer that fixes an illuminator and a photoreceptor to produce a measurement area to be illuminated with measuring light above a stage and to incline their optical axes with respect to a placement surface of the stage in an orientation in which the illuminator and the photoreceptor face the measurement area obliquely downward; a point cloud data generator that generates point cloud data as a set of points including three-dimensional position information representing a three-dimensional shape of a measurement object placed on the stage based on light-reception signals provided by the photoreceptor; a top view map image generator that generates a top view map image representing a plan view of the measurement object as viewed downward from a position right above the measurement object based on the point cloud data; and a display that displays the top view map image.
