SYSTEM AND METHOD FOR CALIBRATING OF OBJECT FOR MEASURING DEFORMATION STRUCTURE

摘要

The present invention relates to a system and a method for calibrating an object for measuring the displacement of a structure, including the following processes of: periodically shooting photographs of a target which is close to one of the cameras installed inside a structure at a predetermined interval; conducting a calibration of the coordinates of images obtained by the photograph shooting process; calculating the interior orientation parameters and the relative orientation parameters of the calibrated images, and conducting an absolute orientation on the same images; and measuring the displacement of the points where the cameras are installed, by calculating three-dimensional coordinates of the target based on the interior orientation parameters and the relative orientation parameters calculated above.
