Technically, this means that the minimum length resolution you are trying to achieve (i.e., the smallest feature that you can visually distinguish) is less than the width of one pixel. There are at least three ways to try to remedy this, and you may need to do a combination of all three:
1. Reduce the working distance between the camera and the object you are scanning. For very detailed scans, I’ve positioned a camera as close as 0.050” above the surface.
2. Increase the desired resolution in the setup. The default is 0.003”. You may need to increase to .010” or larger.
3. Use a higher resolution camera. This effectively gives you more pixels over the same area.
