A Method of Image Interpretation for a New Type of Calibration Target

A new calibration target was designed to overcome the limitations of traditional targets, and an image interpretation study was conducted. Establish a target recognition template based on shooting parameters, use cross-correlation method for template matching, and achieve accurate target localization. The image segmentation was achieved using the gradient method, and the target area was accurately extracted using the method of labeled connected domains. And a center position coordinate algorithm was designed. The experiment proves that the designed calibration board is reliable and practical, and the designed algorithm is robust and accurate.
