So far ... any idea how to obtain if David completes a task (e.g. alignment of two scans)? As time needed to finish a task depends on the scans itself, a recorded routine of mouse actions have to be time-adjusted. This could be done by adding a few seconds after every action (which is dissatisfying) or via synchronizing David software and macros ...

Hi Anti,

I agree with Gunter.
There are different ways to use to have a good alignment.
Even most expensive software like Geomagic design x is using different ways to align single scans together correctly.
You can't use a simple macro or even david sdk to align all kind of geometries toghether :(

My suggestion:
You can control david laser scanner via communication port ; Lots of commands are available in david settings window .
For my own use i wrote the software " Lets scan " to have automatized scanning process like sending command to change any scanning environment , starting scanning , adding scans to the list of shape fusion , controlling turntable and more

Good luck

Hi Narmella,

thanks for your comment. Of course I know that it won't be possible to create perfect models just by align one scan to another. Further steps are needed. But it would help a lot to automate the time consuming process of coarse alignment of that scans. (I scanned about 1400 human skulls within 3 months last year. Now since 4 months I sit in front of my computer and do that stupid and very time consuming click-work while there would be thousands of less annoying works could be done simultaneous. And I just finished about 60 %.)

Hi Simon
The two managed to work at the same time my camera Basler possess .The solution is to install two control cards. Now David checked the fourth panel. Global registration.

It's been a while since I've used Windows API's but SendMessage or PostMessage will control a running application by obtaining the window-handle of David then the button-handle within that window. They will even run from the VBA editor within Excel.

Example code…

Also if you obtain the process-handle you can wait for that process to finish before continuing.

Hi Ingo, I've only a mobile device here so cannot try but I've used similar to this code in the past instead of WinSpy...

Hi ar_kid,
thanks a lot for your suggestion.
I tried it, but there are no results, I can attribute to any DAVID buttons.
It seems, the DAVID GUI is programmed differently.
Best regards

How about using SetCursorPos and mouse_event? It's not a very elegant way of doing it, example on this page...

Hi,
We are using WPF and XAML (.NET 4) for our GUI. I'm not sure about those macros, simulating mouse clicks and buttons... Feel free to do that. We are not preventing those things, I have no idea why it doesn't work. Please understand that we don't actively support that.

I forgot some details:

The screen resolution of my laptop is 2560x1440. I do not know, how much effort is necessary to adjust the script to other resolutions.
Furthermore there are differences between the button positions in different languages due to different word lengthes.
In this particular case it is also necessary to have at least 28 scans in the working directory for the correct position of the buttons on the right side.
Altogether a lot of drawbacks, so I am not convinced, that this is a perfect way for automation.

Best regards
Ingo
