CALIBRATION SYSTEM AND A METHOD FOR MEASURING A WIDTH OF A STRUCTURE BY PROVIDING DATA IN RESPECT OF THE ACCORDANCE BETWEEN A HORIZONTAL AXIS OF THE STRUCTURE AND A HORIZONTAL AXIS OF CAMERA IMAGES

摘要

PURPOSE: A calibration system and a method for measuring a width of a structure are provided to accurately measure a width of a structure by utilizing calibration data because the calibration data with respect to whether horizontal axes of a structure and a camera are parallel or not is provided.;CONSTITUTION: A calibration system comprises a first telemeter(120), a second telemeter(130), template supports(140), a first template(150), a second template(160), an angle frame(170), and a database. The first and second telemeters are respectively arranged to left and right sides of a horizontal direction around a camera. The template supports are spaced from the camera at a predetermined distance and arranged in the left and right sides of the horizontal direction around camera. The first and second templates have the same sizes and are arranged in left and right sides of the template support. The angle frame horizontally rotates the template support according to a rotary angle around a central shaft. The database saves the rotary angle of the template support and a pixel magnification of the second template to the first template according to the rotary angle.;COPYRIGHT KIPO 2012
