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 18):
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 detecting the mobile body stopping at a calibration start location that is a predetermined stopping location for the mobile body for calibration of a camera parameter calculation apparatus, and the processing circuit: (a1) receiving three-dimensional point group data indicating three-dimensional coordinate sets of 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 a three-dimensional coordinate system of the three-dimensional points using the calibration start location, and deciding one or more initial camera parameters of the one or more cameras, based on the one or more mounting locations and the one or more directions 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.
