Imaging apparatus capable of generating three-dimensional images, three-dimensional image generating method, and recording medium

摘要

An imaging apparatus generates a 3D model using a photographed image of a subject and generates a 3D image based on the 3D model. When a corresponding point corresponding to a point forming the 3D model does not form a 3D model generated using a photographed image photographed at a different photographing position, the imaging apparatus determines that the point is noise, and removes the point determined as noise from the 3D model. The imaging apparatus generates a 3D image based on the 3D model from which the point determined as noise is removed.

主权项

1. A 3D model generating device comprising:
a processor configured to: generate a 3D model of a subject using an image of the subject; estimate a photographing direction of an imaging device at a time of photographing of the image based on a point forming the 3D model select a plurality of 3D models having estimated photographing directions that differ by less than a predetermined amount and that have been generated from images with recent photographing times; extract a predetermined number of 3D models from the plurality of selected 3D models in order of photographing time starting with a most recent photographing time, when a number of the plurality of selected 3D models exceeds the predetermined number; and remove a 3D model generated by using an image that was photographed at an earlier photographing time than images used to generate the predetermined number of extracted 3D models.
