Hello Eden

Considering the principle behind photogrammetric matching, it's impossible to obtain any good result with water surfaces (which moves and have reflections) or any other moving or reflective surface. Unless there the water is very very shallow (20 cm or less), perfectly transparent, and you have distinctive features bellow the water, you won't be able to get any matching. The only way to obtain good altimetric results bellow water is to use sonar scanning (the needed equipment depends on your needs and environmental characteristics) or by using LIDAR that supports bathymetric features (usually until 2 Secchi depth).
If you are low on budget it will be a problem because a LIDAR with these features usually costs 75000 US D or a lot more. 
Cheers

Pre-release build updated, so the activation issues on macOS should be resolved now.

Hi Alexey

Confirmed! Everything is working as expected now.
Best Regards

Hello Renato,

Can you please specify the error message that you are observing during the activation?

Hi Alexey

After opening this latest beta, the message in attachment appears. After entering the serial number or activate via terminal, the result is the same, even if "Activation successful" message appears in the terminal. After, the second message in attachment appears (asking to contact your support).
Best regards


PS: Reinstalled previous last beta (15522) and it's working fine, without asking for the license.

This last beta does not assume the previous version 2.0 license. If we reenter the serial number it gives an error.
Is there a workaround?
Best regards

Thank you Alexey for the details.
As a matter of fact, in further tests, this last version works better than version 1.8.4, particularly in bigger projects. Processing times in version 2 are now slightly better that they were in version 1.8.4 consistently.
Great work!
Best regards

we have floating licenses and seems they did NOT work with pre-release version.
Hello Renato,

Thank you for additional information.

We will try to prepare the test version for you and spader this week, that you should be able to test on MacOS configuration, hopefully the reported slow down issue would be resolved in that version and, if so, it will be also fixed in the next public pre-release update.

Hi Alexey

Just tested the version you sent (15512) and it's great!! The processing is more or less on pair with the 1.8.4 version. Probably 8 to 10% slower but much faster than the last beta. The problem seems to be solved. I'll test with all the external GPU's also but, probably, the problem is also gone with that setup. If something will go wrong I'll let you know.

By curiosity, and if it is possible to know, what was the problem?
Best regards

PS: All seems to be fine with the external GPU's. Now the processing times are on pair with version 1.8.4. All solved!!

Hi Alexey

If the diference between 1.8.4 and 2 versions was about 10% processing time it would be great, considering the great new aditions of version 2.
However my processing times are a lot worst than that.
As you suggest, I'm sending the processing logs from the two versions using 2 processing requests in a row. In both cases, as you will see, processing times were worst in the second time. Considering this, probably the "compiling kernels" step is not the culprit. Things seems to slow a lot after this step.
See logs attached.
Best regards

Hello

Version 2.0.0 build 15501 continues to have the problems previously noted in MacOS.
Processing times seem to be slower than last beta. Is there any tweak or improvment that can be done from my side?
In its present state, this version is almost unusable to obtain Point Clouds using macOS. Please try to compare the code with 1.8.4 because this version is working great in this step.

Using only a MacBookPro 16" intel and the included AMD Radeon Pro 5600M, using the same dataset, the build point cloud times are:

Metashape version 1.8.4 - 98.99 sec
Metashape version 2 - 644.256 sec

Best regards

Hi Alexey

It is slower in any situation. With the internal AMD it's less noticeable because, with any eGPU, only the internal GPU seems to be used often but, however, it's a lot slower than version 1.8.4. The external eGPU's have very small periods of usage. With only one, two or three eGPU's, with or without the internal AMD active, things are slower after 8% of the ongoing task. The problem seems to be in the kernels building and loading step. Try to see what's the diference in code between the 1.8.4 and 2 version, in this step, because 1.8.4 it's working just fine.
Cheers

Metashape 2.0 vs 15412 is still too slow with eGPU AMD's and MacOS.
With the same set, hardware and parameters, Metashape 1.8.4 takes a little more than 2 minutes to process what takes 50 minutes (!!!!) to process in Metashape 2.0.
Logs attached.
Cheers

Version 15359 is also very slow. The same problem as before (see logs).

Latest 2.0 version, from 7th november, is still very slow (unusable) in MacOS with AMD's eGPU's. Kernel building and loading while building the Point Cloud does not pass 8% for a while and takes ages to reach 14%. Version 1.8.4 (current stable one) is fine.

Hello Renato,

Can you share the log from 2.0.0 for any GPU supported stage from starting the task up to the point when it gets slow?


Hello Alexey

I'm sending the logs from Vs2 and Vs 1.8.4 in exactly the same hardware conditions and with the same set and parameters.
I had to stop the processing of Vs 2 after 11% because it was not doing nothing. You will notice quickly that after OpenCL kernel building, things advance very slowly. Everything is ok with version 1.8.4.
Cheers

The problem I've talked about before may be a problem from the MacOS version only.
Version 1.8.4 is working fine here but the most recent ones do not.
I'm using external AMD 6800 and 6900 XT. It can be something related with that too.
