Abstract:
Three-dimensional point group data indicating three-dimensional coordinate sets of three-dimensional points included in a common imaging space of one or more cameras is received, one or more images captured by the one or more cameras are transmitted, the one or more transmitted images are received, initial camera parameters of each cameras are decided based on one or more mounting locations and one or more directions of the cameras, corresponding points in the one or more images are calculated for each of the three-dimensional points, based on the three-dimensional point group data and the initial camera parameters, and one or more camera parameters of the one or more cameras are calculated based on pixel values at the corresponding points in the one or more images.

Claim (Index 17):
A camera parameter calculation system, comprising:\n a three-dimensional laser scanner that is installed in a fixed manner in a common imaging space of one or more cameras; and a processing circuit that calculates a camera parameter of a camera installed on a mobile body, the three-dimensional laser scanner measuring a location and a direction of the mobile body in a three-dimensional coordinate system of three-dimensional points included in the imaging space, and the processing circuit: (a1) receiving three-dimensional point group data indicating the three-dimensional coordinate sets of the three-dimensional points included in the imaging space; (a2) transmitting one or more images captured by the one or more cameras; (a3) receiving the one or more images transmitted in process (a2); (a4) calculating one or more mounting locations and one or more directions of the one or more cameras in the three-dimensional coordinate system, based on the one or more locations and the one or more directions of the mobile body measured by the three-dimensional laser scanner, and deciding one or more initial camera parameters of the one or more cameras, based on the mounting location and the direction of the one or more cameras; (a5) calculating corresponding points in the one or more images received in process (a3), for each of the three-dimensional points, based on the three-dimensional point group data received in process (a1) and the one or more initial camera parameters decided in process (a4); (a6) calculating one or more camera parameters of the one or more cameras, based on pixel values at the corresponding points calculated in process (a5), in the one or more images; and (a7) outputting the one or more camera parameters calculated in process (a6), the one or more cameras having a one-to-one relationship with the one or more initial camera parameters, the one or more cameras having a one-to-one relationship with the one or more images, and the one or more cameras having a one-to-one relationship with the one or more camera parameters.
