Calibration problem #2

Closed negantia closed 8 years ago

negantia commented 8 years ago

Hi,

I am going to perform the 3d scanning of the object using the slstudio in educational purposes. I use the Imaging Source camera DMK22BUC03 (mono),Panasonic LCD Projector PT-L520E, and computer with processor 4x AMD A8-6600K APU with Radeon(tm) HD Graphics and operating system - Ubuntu 15.04 (x86_64). Following the provided readme file I have successfully compiled the sources, having previously installed all the dependencies. So, I have Qt version 4.8.6, QMake 2.01a, OpenCV 2.4.9, PCL 1.7 and VTK 5.8. In order to make it work with my camera I wrote specified camera class containing the methods, which override the virtual ones of Camera.h class and finally can see a good mono picture in calibration window. I have connected the projector to system unit using the VGA cable, monitor to system unit using a DVI one. And try to perform calibration of camera and projector using the provided software and having the following settings: Preferences->Pattern Mode - 2x3 Pattern Phase Shift, Camera - Imaging Source DMK22BUC03, Trigger Mode - Software. Everything I have in projector checkbox is 1) Screen 0: 1280x1024 , 2) SLStudio Virtual Screen 3) LC3000 API and 4)LC4500 API. However if I check the #1 I'll see only the white screen after pressing the "Perform Calibration" button (if I don't use projector, and 2 white screens if I use it and 2 monitors DVI and VGA with help of ARandR). If I check #2 I'll see the stream from my camera but no patterns appear after "snap" (as they do in your video https://www.youtube.com/watch?v=swszXuPxGZI ).

Can you recommend something?

Looking forward to your answer. Thank you in advance.

Hello negantia, please excuse me for not answering before now. Are you still having issues? Per default, slstudio builds with OpenGLContext.Unix.cpp, which uses old-fashioned XScreens to separate the projection display from your window manager. It requires you to set up the projector as a separate second X screen. If you compile with OpenGLContext.GLFW.cpp instead, the XRandR method is used instead. Please try doing this. Regards, Jakob
