Can't get a normal aspect ratio in projection
« on: April 15, 2019, 08:53:20 AM »
Hello Nelson,

After a long trip, we finally get the galvos work. But the ratio of the projection seems not to be normal.(also, the projection is upside down but it can be adjusted.)
By the way, the preview in the Simulator is normal, and the laser projector is horizontal.

And also, we want to know if the openlase can do a work like "projecting what the camera is recording" in real-time. Is somebody did like this? There are so few comments about the details of Openlase and I get no idea how to use the "cal" or "invert" of it, so as using openlase in real-time. Hope to get some help! Thank you so much!

Hi Zang,

Glad you were able to identify the problem with your galvo setup.

If you use lasershark_stdin no keystone configuration option is provided. If you use OpenLase you can use the JACK audio connection kit to route the output through OpenLase's "output" application. This program will allow you to keystone/etc which sounds to be what you are looking for.

This should all be possible to do in realtime

Hi Nelson,

Thank you very much for your continued advice!

I'm a little confused about this.

When using the lasershark_stdin_circlemaker through lasershark_stdin(not through the .txt), its aspect ratio is also strange. And when using openlase, ./lasershark_JACK is needed instead of the ./lasershark_stdin, in my opinion. So I still don't know how the problem could happen. :-X
