1. A measuring apparatus comprising:
an irradiator to irradiate an object with light;
an imager to capture an image of the object irradiated with the light and generate captured image data; and
circuitry configured to:
measure the object based on the captured image data generated by the imager;
estimate an incident angle of the light from the irradiator irradiating an invalid region;
calculate position and posture information based on the incident angle that has been estimated; and
adjust, based on the position and the posture information relative positions among the object, the irradiator, and the imager,
wherein the incident angle is estimated with respect to a normal direction to a surface of the object, and
wherein the circuitry is further configured to:
control the imager to capture an image of the object with the relative positions that were adjusted, to generate supplementary image data to be used in the invalid region; and
supplement the invalid region with the supplementary image data.
