Document Type and Number:
WIPO Patent Application WO/2016/157802
Kind Code:
A1
Abstract:
In order to calculate a coordinate transformation between coordinates of a camera coordinate system and coordinates of a world coordinate system, regardless of target regions, an information processing apparatus according to the present invention includes: a small region grouping means for dividing small regions, which are formed on the basis of points having three-dimensional information about a location in a terrain corresponding to a region included in captured image data captured by an image capture device, into small region groups, which are groups of a small region, on the basis of the normal direction and altitude of the small region; and a coordinate transformation table creation means for creating a coordinate transformation table which contains information for the coordinate transformation between the coordinates of the camera coordinate system, which are coordinates in the captured image data, and coordinates of the world coordinate system, which are coordinates in a small region that corresponds to the captured image data, using the small region groups and candidate information which is related to the coordinate transformation.
