COORDINATE CALCULATOR AND COORDINATE CALCULATION SYSTEM

摘要

A coordinate calculator (100) includes: an image processing unit (103, 141, 142) configured to calculate a coordinate of an attention point from a plurality of images captured by a plurality of imaging units (131, 132); a transmitter (102) configured to transmit the calculated coordinate to a connected separate information processing device (200) using a built-in function included in an operating system of the information processing device (200); a receiver (102) configured to receive calibration information of the imaging unit (131, 132), the calibration information being calculated by the information processing device (200) based on the transmitted coordinate and transmitted by the information processing device (200) using a built-in function included in the operating system of the information processing device (200); and a storage unit (105, 144) configured to store therein the received calibration information.
