| description | Provided is an image processing apparatus including a processor. The processor is configured to: reconstruct, by employing an image set acquired by means of an endoscope, three-dimensional information of an imaging subject; estimate, by means of an estimator, imaging-subject distances from the image set by employing a learning parameter; calculate, on the basis of the estimated imaging-subject distances and the imaging-subject distances in the three-dimensional information, a scale coefficient; convert relative dimensions of the three-dimensional information to absolute dimensions by employing the scale coefficient; and output the three-dimensional information containing the absolute dimensions. The learning parameter is determined by learning a plurality of learning images including images of imaging-subject distances outside a measurement range in which imaging-subject distances can be measured on the basis of contrast of the image and a position of an autofocus-lens, as well as imaging-subject distances for each of the learning images. |
