APPARATUS AND METHOD FOR OPTICAL AXIS ALIGNMENT OF VISIBLE LIGHT SENSOR AND INFRARED RAY SENSOR

摘要

PURPOSE: An apparatus and a method for optical axis alignment of a visible light sensor and an infrared ray sensor are provided to automatically perform optical axis alignment, thereby saving time and efforts required for the optical axis alignment. CONSTITUTION: A reflection unit(300) selectively reflects light so that visible light from a subject is delivered to a visible light sensor(100) and infrared ray from the subject is delivered to a thermal imaging sensor(200). A control unit(400) produces displacement of an optical axis from comparison between an image photographed by the visible light sensor and an image photographed by the thermal imaging sensor, and makes optical axes of the visible light sensor and thermal imaging sensor be coincident with each other by adjusting at least one or more of the visible light sensor, thermal imaging sensor, and reflection unit.
