Constantly increasing Dense Cloud build estimate

[pch90265]

Hi there,

Another noob question for all of you...  I am building a dense mesh from approx 120 cameras.  When the run starts, it estimates 3.5 hours.  Thirty minutes in, the estimate is a further 4.5 hours.  One hour in, the estimate is 7 more hours. 

Through this process, the progress bar is chugging along, but the time seems to keep getting longer and longer.

Is this normal?

I'm on a Dell T7910, dual Xeon, 128GB of RAM, dual Quadro K5200's...  not a lightweight machine.

Appreciate any guidance on this topic.

Thanks!!!

Further example of the above....  110 cameras, 19.3K Tie Points, images are 36 MP from a Nikon D800:

7:00 am -- 3:15 to go
7:15 am -- 4:15 to go one minute, then 5:15 the next
7:30 am -- 5:31 to go
7:45 am -- 6:07 to go
8:15 am -- 6:05 to go -- 18% done
8:30 am -- 6:15 to go -- 22% done

Is this normal???

Apparently normal


I get the same thing on complex projects.

It like it's building it's time estimate as it goes along.

Once the estimate finishes going up, it appears to be pretty accurate coming back down

The ETA is just an estimation of how much % is done in the time it needed to do that.
So if the percentage goes up from 1% to 2% and this takes an hour to process. It will say that it has like 100hours left.
But most steps for the Dense cloud are not lineary hence the ETA it shows isn't very helpful until it really starts to get going. As time goes on, the ETA will become more accurate.
