How to ensure high metrology accuracy? 

1.  What should I watch out for when taking pictures?

2.  What is a good reference?

3.  Does it make a difference if the metrology algorithm can infer the camera motion automatically?

4.  What is the best way to take pictures to ensure that the metrology algorithm can infer the movement of the camera automatically?

5.  How come I got different results when I take the same measurements on the same pairs of images multiple times?

6.  How come I got different results measuring the size of a repetitive pattern (e.g. picket fence, windows) in the same image?

7.  Do you provide a solution to correct for camera lens distortion?

8.  Sometimes when I see the message “Please specify at least 6 correspondences for further processing”, I notice that measurement results can change quite a bit with each additional correspondence added.

9.  What happens if I got bad results?
