Troubleshooting TVGO Processing Error: Missing or Unreadable Camera Data

📌 Problem

During TrueView GO (TVGO) processing, the TGO job may fail with error messages similar to:

ERROR_CAMDATA_NOTFOUND
ERROR_READ_FAIL
ERROR_CAMERA_INVALID
ERROR_Lidar_Solve_Failed

These messages indicate that required camera data for the cycle could not be found or read during processing.

🧠 What This Means

TVGO processing requires valid camera imagery and associated metadata for each cycle. If these files are missing, incomplete, or unreadable, processing cannot continue and the SLAM solution will fail.

Common indicators include references in the log to missing folders such as:

...\RawData\<CycleName>\IMG

or missing time synchronization files under:

...\RawData\<CycleName>\GPS\Time

🔍 Root Cause

• Incomplete data transfer from the unit
  The cycle was copied off the device using an interrupted or unreliable transfer, resulting in missing files.
• Corrupt or partially copied files
  Some files exist but cannot be read due to corruption or an incomplete copy operation.
• Cameras were disabled during capture
  If cameras were turned off at collection time, required image files will not exist for that cycle.
• Manual modification of RawData
  Renaming, moving, or selectively copying files inside the RawData folder can break required file references.

✅ Probable Resolutions

1. Re-copy the data from the TrueView GO unit
   Delete the existing local copy of the affected Cycle and copy it again directly from the unit. Use a protected data copy tool, like TeraCopy or Robocopy, to transfer the data from the TVGO to the PC. Or, use LP360 v2025.1.151.11 or later to import the TrueView GO Cycle directly from the connected TrueView handheld laser scanner using the robust copy of the Import Cycle tool.

2. Verify the cycle folder structure
   Confirm that the following folders exist and contain files:

   RawData\<CycleName>\IMG
   RawData\<CycleName>\GPS\Time
   

3. Confirm cameras were enabled during capture
   If the cameras were disabled at collection time, the cycle cannot be processed with camera‑based SLAM. In this case, the data must be re‑collected.
4. Avoid modifying RawData folders
   Do not rename, move, or remove files within the RawData directory before processing.

📚 Additional Notes

• This issue is related to data integrity and is not caused by licensing or coordinate system settings.
• Processing will fail early if required camera data is missing or unreadable.
