Abstract: A calibrator for a camera includes a controlling circuit, a photographing circuit, a calculating circuit, and an instructing circuit. The controlling circuit is configured to control a movable body to move into a shooting area of the camera. A marker is provided on the movable body for calibration of the camera. The photographing circuit is configured to control the camera to photograph the marker. The calculating circuit is configured to calculate at least one parameter of the camera based on the photographed marker. The instructing circuit is configured to transmit the at least one parameter to the camera to calibrate the camera.

Abstract: A three-dimensional model generating device includes: a converted image generating unit that, for each of input images included in one or more items of video data and having mutually different viewpoints, generates a converted image from the input image that includes fewer pixels than the input image; a camera parameter estimating unit that detects features in the converted images and estimates, for each of the input images, a camera parameter at a capture time of the input image, based on a pair of similar features between two of the converted images; and a three-dimensional model generating unit that generates a three-dimensional model using the input images and the camera parameters.

Abstract: A multiple viewpoint image capturing system includes: a plurality of cameras that capture videos in a predetermined space from different positions; a circumstance sensing unit that senses at least one of circumstances of the respective cameras and circumstances of the predetermined space, and outputs the sensed circumstances in a form of capturing circumstance information; and an event detector that detects a predetermined event based on the capturing circumstance information, determines whether to perform camera calibration in a case of detecting the predetermined event, and outputs camera calibration information that indicates the camera calibration to be performed in a case of determining that the camera calibration is to be performed.

Abstract: Provided is a three-dimensional reconstruction method of reconstructing a three-dimensional model from multi-view images. The method includes: selecting two frames from the multi-view images; calculating image information of each of the two frames; selecting a method of calculating corresponding keypoints in the two frames, according to the image information; and calculating the corresponding keypoints using the method of calculating corresponding keypoints selected in the selecting of the method of calculating corresponding keypoints.
