Title:
CALIBRATION DEVICE, CALIBRATION METHOD, AND CALIBRATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/098971
Kind Code:
A1
Abstract:
Provided is a calibration device that, when a plurality of distance sensors are installed in a certain region, can ease the workload of calibrating the position and orientation of each distance sensor. In a measurement computation device (100), a social group identification unit (5610) identifies group candidates that can be identified as groups among movement measurement subjects in each laser rangefinder, a group comparison unit (5612) identifies matching groups for each pair of laser rangefinders, and calculates the relative position of each pair of laser rangefinders by means of the position and orientation of the identified matching groups, and a network position identification unit (5620) calibrates the position and orientation of each laser rangefinder in a sensor network coordinate system in a manner so as to minimize the position error of a subject observed in common by each pair.
