Calibration guide

Important: if the images end in “TIF” and not “tif” (lowercase vs. uppercase), the program will try to overwrite the images with the xyz files. If you rename all extensions to lowercase tif, the program will correctly append _xyz.txt at the end.

Adam's Images

• Step 5 not entirely clear - this is the number of dots in a row inside the area that we selected with the red rectangle.

I think Dots in a Row is on your looking image.

• Step 8 - the piece of tape on the target is southwest of and pointing to the center point, which is at (4,4). Remembering that we only count the dots within the area that was selected with the red rectangle, determine the coordinates of the point at the bottom left corner.

I think the number of missing row and column only depends on the region of red rectangle for

       which you will drag.  I used 1 and 1 for each starting

• Step 10 - This is the distance from the camera to the target at the time each frame was captured.

I think it means the distance data we will measure for each frame.

       distance data is in zlist.txt.

Calibrate steps 1 and 2: are the XYZ and the ROW COL files the ones in the same directory as calibrationsystem.exe (/windowsbins)

   
        calibrate stage2 seems to use xyz_file and rowcol_file produced in the directory at which 
        calibrationsystem.exe is located. I think both files have accumulated data set from
        all frames used in dot finder.
