Information processing device, information processing method, imaging device, and information processing system

An imaging device comprising:

• at least two imaging elements that photograph images of a predetermined space;
• an optical system that forms images of the predetermined space on the at least two imaging elements;
• a storage unit;
• and
• a control unit,
• wherein
• the storage unit stores distortion information based on at least one of characteristics of the optical system and errors in the placement of the imaging elements, and
• the control unit generates depth information of the predetermined space based on images obtained by photographing the predetermined space with each of the at least two imaging elements, and outputs the depth information and the distortion information.

An information processing system comprising:

• an information processing device;
• and
• an imaging device,
• wherein
• the imaging device includes
• at least two imaging elements that photograph images of a predetermined space,
• an optical system that forms images of the predetermined space on the at least two imaging elements,
• a storage unit, and
• a control unit,
• the storage unit stores as distortion information at least one of characteristics of the optical system and errors in the placement of the imaging elements,
• the control unit generates depth information of the predetermined space based on images obtained by photographing the predetermined space with each of the at least two imaging elements, and outputs the depth information and the distortion information to the information processing device, and
• the information processing device acquires the depth information and the distortion information from the imaging device and corrects the depth information based on the distortion information to generate corrected depth information.
