Abstract

To provide a three-dimensional vision camera where no disagreement is caused between two-dimensional image information and distance information, the three-dimensional vision camera is provided with a memory (11), a neural network (12) and a three-dimensional image synthesizer (13). In the memory (11), image data of a photographic object shot from different directions are stored. Information necessary for converting the image sensed by an image sensing device (2) into a three-dimensional image is read out from the image data of the memory (11) by the neural network (12). A three-dimensional image is produced by the three-dimensional image synthesizer (13).

Claims

1. A three-dimensional vision camera comprising:

an image sensing device;

an optical system for directing a light beam from a photographic object to the light sensing device;

a memory in which a plurality of image data are stored;

a neural network which obtains three-dimensional image information of the photographic object based on an image sensed by the image sensing device and the image data stored in the memory; and

an image synthesizer which synthesizes the image sensed by the image sensing device and the three-dimensional image information obtained by the neural network into a three-dimensional image.

2. A three-dimensional vision camera according to claim 1, wherein said plurality of image data stored in the memory are image data of the photographic object shot at different angles.
