Correlation matrix disappeared?
« on: May 23, 2020, 03:25:28 AM »
I've been running a series of tests with the same imagery (multiple conversion-to-jpeg parameters) and in one case, the correlation matrix disappeared in the chunks that were copied (via script) from the initial alignment chunk. I can't see anything different from the other projects - the alignment and optimization and script are all run in batch - (1) align, (2) optimize, (3) run script.

The script copies the original chunk and runs gradual selection, saving a new chunk each time it optimizes to a threshold value for first Reconstruction Uncertainty, then Projection accuracy, then Reprojection Error. All of the copied chunks have the correlation matrix grayed out.

I just tried copying manually and the correlation matrix survives the copy. I'll try running just the script again, guessing it will work, but wondering what would cause this...

Hello andyroo,

Can you specify the steps performed by the script? Is that correct that you mean that chunk.copy() command doesn't transfer the correlation matrix to the chunk's copy?
