OMC Technical Brief – Camera Calibration Camera calibration is all about getting the best geometric information from your images Introduction The development of camera calibration Considering the importance of many image- techniques spans much of the past century and processing applications it has always been most of what can be known about the topic can surprising how few tools were available for be understood by reading the literature relating to measuring and then correcting image distortion. photogrammetry. However, over the past few years the situation has improved. This technical brief reviews the Historical summary - how camera calibration historical development of camera calibration models evolved methods and models. Photogrammetrists have extracted more geometric information from cameras than almost Recognising distortion in your images any other group. Applications are diverse, for The largest distortion that you are likely to instance, virtually all maps have been created encounter in a typical image is called radial from aerial imagery where the development of distortion. The distortion in an image using fish camera calibration methods derived from eye lens is an extreme example. To check photogrammetric principles. Today cameras can whether this is noticeable in your image look at be found measuring virtually everything and any image where there is something straight in photogrammetric principles are often ...
