TIDEP0076 AM572x-based DLP Calibration demo:error:CARLIBRATION_PARAMETERS_MODEL_SIZE_MISSING

Other Parts Discussed in Thread: TIDEP0076

I follow the TIDEP0076 guide,when I come to the DLP Calibration,I meet an error:CARLIBRATION_PARAMETERS_MODEL_SIZE_MISSING.

It seems that I do not generate an calibration/camera_images/camera_calibration_board.bmp.
Here is the steps what I did:

1. ./DLP_LIGHTCARFTER

2. OPTION 2:Prepare DLP LightCrafter 4500

3.OPTION 3:Prepare system for calibration and scanning

4.OPTION 1:Generate camera calibration board and enter feature measurement.

Then I meet the error.

If someone can tell me why?a
