© proDAD GmbH This is how you recognize a successful Calibration: a) The analysis finds at least 20 images (Counter = green), ideally even 50+ images, on the basis of the geometrical points that were recognized. b) There are no longer redly flashing areas in the Tab for the Grid histogram on the right. That means that all the areas that were necessary for the calibration have been captured in step1 and 2. The more areas you capture, the better the results of the latter corrections of your videos.
© proDAD GmbH c) Successful analyses and profiles resulting from them will be marked as "", less successful ones as "". d) Good Profiles will be displayed with a "Total Average Error" below 0,3. Excellent profiles can even reach values between 0,1 and 0,15. e) Whether the profile you have generated works in practice, can be seen after the analysis. Switch from "Calibration Grid" to "Viewer" and activate the splitscreen view "Compare View".

In the Graph register there are diagrams with the data of the analysis of the calibrated video. The Grid Histogram shows the areas that were not recognized in the calibration (blinking red). It indicates in which positions the chessboard has not been recognized. The ideal case is when there is no red area in the histogram.
© proDAD GmbH The data of the analysis of the calibrated video are shown in the Parameter register. There is an Instruction Video available in the tips register. The video explains the Calibration Grids and contains useful tips for Calibration and provides links to important information.
© proDAD GmbH Viewer In the View Mode area you can choose between 3 different preview options (Viewer). 1. View Result 2.
© proDAD GmbH 3. Compare View (Split View, before/after) Additional correction Here you can adjust Tilt, Shift and Zoom to correct the so-called Perspective Distortion. Perspective Distortion are lines and edges in photos that head towards each other due to the characteristics of the lens, even though in reality the lines are parallel. This effect occurs, when the edges of the subject are not parallel to the projection surface. This happens, for instance, when the camera is held in an upward inclination.
