PROCEDURE 1: CALIBRATING SEPARATELY
Select Calibration… Calibrate Camera 1 from the menu bar. Proceed as with stereo calibration; repeat for Camera 2. At this
point, you may check the Calibration tab at the left side of the main window and confirm that both cameras are calibrated
but the Transformation section shows “Not calibrated”.
.
Next, you will need a single image of a speckled target to complete the orientation calibration. Any shape may be used for
this, but the target must contain a known distance marked off with two recognizable end points. This will be necessary to
establish scale later in the process. Typically this can be accomplished by simply making two small black “X” marks on the
specimen and carefully measuring the distance between them. These points should be relatively far apart for best accuracy.
NOTE: EXTERNAL ORIENTATION ELIMINATES THE NEED FOR THE GRID CALIBRATION IMAGES TO BE SYNCHRONIZED, SINCE
THEY WILL BE CONSIDERED SEPARATELY. HOWEVER, FOR THE SPECKLE IMAGE, YOUR CAMERAS MUST EITHER BE
SYNCHRONIZED, OR THE TARGET MUST BE IMMOBILE.
