I have finished rewriting all the subroutines now and I have manage to increase the speed even more. When rewriting, I got rid of any grossly underperforming code and now at 100mm/h it runs through in just under a second.
But once again, the errors are still plaguing the system. At this rainfall rate there are quite a few ghost drops and therefore still quite a lot of missed drops. The one I have just done is at 9% and I can clearly see at least 2 ghost drops. Have to investigate this further.
However, I think its about time I stopped for Christmas, so I don’t think I will be doing much except maybe showing a few people what I have done over the holidays.
Merry Christmas all!
Update
Just a quick update, I continued tarting up the code, and it now reports all ghost drops and all missing drops and why they were missed (ghosting/verification/etc.). Ive just done a beefy test at 100mm/h over 1 second:
run(’..\..\Create Samples\V0_7\V0_7′); V0_9;
7966 Drops Generated
Elapsed time is 143.394716 seconds.
12.7% Error
Thats without all the warning and debug messages. As a results Ive found that the thresholding/peak detection routine does not always find all the pulses. In fact, it only finds them at very slow rain rates. As a consequence I have had to pad the data so they are all the same length. So I am definitely going to have to look into that.
The graph also now shows the errors so it makes them easier to pick out. So just for formality, here are a few screenshots and program outputs:
run(’..\..\Create Samples\V0_7\V0_7′); V0_9;
