Interpret Calibration Results

Post by ytzhang » Thu Mar 27, 2014 12:46 pm


I have setup 12 Flex 3 cameras covering a volume about 14ft-14ft-9ft. The Calibration Engine shows exceptional over result and very high overall quality. But I wonder more detailed interpretation of the results.

1. In the Calibration Engine, columns are ‘Cam’, 'Samp', 'Quality', 'Focal', 'MeanEr', 'PixelEr'. What are these standing for? The first two rows are 'Ave' and 'Wand'. All values for 'Wand' are larger than those for 'Ave'. What does this imply?

2. After clicking 'Apply results', the window of 'Calibration Result Report' has a row 'Triangulation'. What do 'Recommended 6.2mm' and 'Residual Mean Error 1.1mm' mean?

Thank you!
