I have used a moon surface image for measuring the crater diameter. When I'm using the Crater Helper, I found that the diameter numbers are wrong. They are not the actual distance for the real situation but the distance for the picture. For example, the actual distance for diameter could be more than 20 meters but the measured one is only 0.03 meters. Who could tell me the reason?

The program doesn't show the exact distance because you haven't specified the scale of the image. In order to fix the problem, you will need to specify the scale of the image using the Scale option. If you don't know the scale of the picture, I recommend you contact the author of the photo.
