Error Scanning :: Not Enough Correspondences


Hello all,

I got this message and also sometimes the program is stuck on "Initializing".

Does this mean the scene is not dark enough to get a good scan?


  • Hi Lilly,

    So sorry for any inconvenience this has caused you. This error usually means that the items in the scene are too dark to scan, the projector isn’t bright enough to scan the items, or the projector is too far away. What projector are you using?

    When scanning this scene again, could you try the following?:

    1. Turn on “safe mode” and turn off “Apply Mask” under Advanced Settings in the new scan view
    2. If that doesn’t work, move the projector closer to the scene and/or zoom the projector in

    If none of that works, could you post pictures of the scene you're trying to scan? This would help us better understand what's going on.

    You can read about the scanning process and conditions that affect the scan in the following articles: &

  • Hey!

    I am also receiving the same error message while trying to get my first scan of the test paper you included. I have made things bigger, smaller, lighter , darker and am still met with "not enough correspondence" any suggestions. Picture attached.

  • Hi Adam- In the picture, it looks like the LFC is not transmitting an image to the projector (you should see a checkerboard-ish image when it's plugged in). Can you see if your projector needs to have the input switched manually to the LFC? Does another computer/laptop work with that projector?

    When you begin a scan, you should see some dots and barcode like patterns appear. Do you ever see those?

  • Hey Kevin!


    Thanks for the quick response, like a super noob I totally forgot to set the input on my projector to HDMI !. As soon as I did that it was all good. Thanks again!
