2014-10-11 04:41:32 -0600 | commented question | Device or resource busy And what do you suggest I do? No Threads? How do I properly close the video stream? |
2014-10-11 04:11:36 -0600 | commented question | Device or resource busy Yeah I thought so, but how do I close it properly? |
2014-10-11 03:34:00 -0600 | commented question | Device or resource busy The 2 threads run fine if I don't use registerCameras(). I need to register them because I have 3 cameras and need to know which one is left or right. |

2014-10-11 00:59:47 -0600 | commented question | Capture of 3D videos I don't think you seem to understand how OpenCV works. Google if you find some source which may have an working algorithm. I think here you'll only get tips on how to write it yourself. |
2014-10-11 00:16:34 -0600 | asked a question | Device or resource busy Hi there, I'm trying to write a program that uses 2 cameras. In the first step I open the cameras on by one for configuration (which is left, right, not to use and so on). After that I open the left and right camera each in on thread. I close the configuration with: destroyWindow(id); cap.release(); The Problem is after the configuration I get the following massage when I try to open the capturing: Another thing thats happening is that the camera window stays open for much to long. I put a sleep(60) after closing the video feed and the window stays open until the sleep is over. It's like the command is not even executed when the command is given. Edit: Full Code in here: http://pastebin.com/MgYen8pL The important part is the main function and the registerCameras function. |

2014-10-09 22:43:06 -0600 | answered a question | Setting up OpenCV2.4.10 with C++ I usually compile programms by exporting the path with:
export LD_LIBRARY_PATH=/usr/local/lib
and then compile with
g++ So far I haven't figured out a way to do it otherwise. Hope that might help, good luck. P.S. ups, you're using windows. Since then I think the commands won't work. I don't know how to run this on windows, sorry. |

2014-10-04 23:46:14 -0600 | asked a question | Where do I find information about the methods of structures? Hi there, I was looking over some opencv code and wanted to know what the .depth() method of an mat object does. However I failed to find any reference. http://docs.opencv.org/modules/core/doc/basic_structures.html Lists the Mat Object but says nothing more than that it has methods. Where do I look stuff like this up? Thanks in advance. |

Anyone an Idea whats wrong. SOLVED: I previously change the java version from 1.6 to 1.7 using sudo update-alternatives --config java I changed it back and everything compiled sucessfully. |

2014-10-03 21:23:16 -0600 | asked a question | Compilation errror: XY was no declared in this scope I there, i was trying to follow this tutorial: http://docs.opencv.org/doc/tutorials/core/how_to_scan_images/how_to_scan_images.html#howtoscanimagesopencv and tried to compile the sample code given here: http://docs.opencv.org/_downloads/how_to_scan_images.cpp and get the following error: I was using the following compilation command The Code itself is correct, so why do I still get this error. Edit: I'm using Debian Linux and OpenCV 3. Thanks in advance! |
