Hello,
I just picked up a laptop with an F200 in it, and am working on a quick tech demo for the camera.
I am working in the Processing IDE right now, for quick iteration. But will move this directly to java after the demo. I am combining Segmentation with basic face tracking to create a consistent green screen effect during head movement.
The problem comes up in the following part of the code: (Full source linked in gist at end.)
PXCM3DSeg segmentation = senseMgr.Query3DSeg(); if (segmentation != null) { PXCMImage segmentedImage = segmentation.AcquireSegmentedImage(); if (segmentedImage != null) { PXCMImage.ImageData dData = new PXCMImage.ImageData(); segmentedImage.AcquireAccess(PXCMImage.Access.ACCESS_READ, PXCMImage.PixelFormat.PIXEL_FORMAT_RGB32, dData); //imgDepth = dData.ToPImage(0, imgDepth); segmentedImage.ReleaseAccess(dData); image(imgDepth, 0, 0); } else { println("null segImage"); } } else { println("null seg"); }
Everything runs perfectly with that line commented. But if I uncomment it, I get about 4 frames of Seg data (with a lot of artifacting in the bottom.) then the following crash:
# # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000006495c250, pid=10424, tid=4980 # # JRE version: Java(TM) SE Runtime Environment (7.0_40-b43) (build 1.7.0_40-b43) # Java VM: Java HotSpot(TM) 64-Bit Server VM (24.0-b56 mixed mode windows-amd64 compressed oops) # Problematic frame: # C [msvcr100.dll+0x3c250] # # Failed to write core dump.

I can provide the error report file if necessary
Again, nothing ever crashes until I start to call 'toPimage'
Unfortunately I don't see a way to get at the source of toPimage to see if it is an issue due to the alpha channel? Is there source available for the Processing library? Is there a workaround to not use toPimage that you would recommend?
To reproduce this, here is the current full source: https://gist.github.com/BorisKourt/8ac77261731000be2fb6#file-trackingandremoval-pde-L86
Any help/source/workarounds would be supremely appreciated!

Fixed by adding:
senseMgr.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR, 1280, 720, 30);
In setup. I have updated the linked gist to the latest code.
Best

Hi
I just found your thread on toPimage. It looks like you fixed the problem with this function. To me it seems like the function was completely removed from the library now. I opened a thread on that topic https://software.intel.com/en-us/forums/realsense/topic/671777
Does your code still work for you? Are you working with an older version of the library? If so could you provide a download for the working library?
Regards

public PImage ToPImageCopy(int var1, PImage var2, PXCMImage.ImageData cData) { var2.loadPixels(); cData.ToIntArray(var1, var2.pixels); var2.updatePixels(); return var2; }Please tell me if more Modules are available to you in Java. As per this thread: https://software.intel.com/en-us/forums/realsense/topic/611503 I found that I couldn't access most of the Modules, and unfortunately I don't know if I was doing something wrong or if they are actually un-implemented. Good Luck! Boris PS: Ping me if you have any other questions, I spent quite a bit of time trying to wrap my head around this earlier this year.
