Abstract: There is provided a parcel recognition device that recognizes parcel based on a color image including one or more parcels, the device including: a processor; and a memory, in which by cooperating with the memory, the processor estimates a region of the one or more parcels in the color image, switches a color of a background which is a region excluding the region of the one or more parcels in the color image, and recognizes each of the one or more parcels based on the background having the switched color and a color of the region of the parcel.

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 three-dimensional model generation method executed by an information processing device includes: obtaining a first three-dimensional model from a measuring device that emits an electromagnetic wave and obtains a reflected wave which is the electromagnetic wave reflected by a measurement target to thereby generate a first three-dimensional model including first position information indicating first three-dimensional positions in the measurement target; obtaining a multi-viewpoint image generated by one or more cameras shooting the measurement target from different positions; and generating a second three-dimensional model by enhancing the definition of the first three-dimensional model using the multi-viewpoint image.

Abstract: A three-dimensional model generation method includes: obtaining subject information including a plurality of positions on a subject in a three-dimensional space; obtaining a first camera image of the subject from a first viewpoint and a second camera image of the subject from a second viewpoint; determining a search range in the three-dimensional space, including a first three-dimensional point on the subject corresponding to a first point in the first camera image, based on the subject information and without using map information that is generated by camera calibration executed by shooting the subject from a plurality of viewpoints and includes three-dimensional points each indicating a position on the subject in the three-dimensional space; searching for a similar point that is similar to the first point, in a range in the second camera image corresponding to the search range; and a generating three-dimensional model using the search result.
