OpenCV in WorldViz

[sircedric4]

Thank you very much. I put the files in the directories you specified, though I put them in the appropriate place in the Vizard31 folder instead of Vizard30. I am trying to get the squares.py sample to work in Vizard and I get this error:

Traceback (most recent call last):
File "<string>", line 11, in ?
File "squares.py", line 8, in ?
from opencv.cv import *
File "C:\Program Files\WorldViz\Vizard31\bin\lib\site-packages\opencv\__init__.py", line 55, in ?
from cv import *
File "C:\Program Files\WorldViz\Vizard31\bin\lib\site-packages\opencv\cv.py", line 5, in ?
import _cv
ImportError: DLL load failed: The specified module could not be found.

Do I have to do anything special to register the DLL's or am I missing one? Has anyone encountered this error message before?

Is there an _cv.pyd in site-packages/opencv? What is the value of sys.path?

[sircedric4]

There is a _cv.pyd in the site-packages\opencv path. I do not know what you mean by the value of sys.path.

If you are referring to the PATH environment variable in my Windows XP operating system. That value is:

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Common Files\Roxio Shared\9.0\DLLShared\;C:\IFOR\WIN\BIN;C:\IFOR\WIN\BIN\EN_US;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Windows Imaging\;%OSG_BIN_PATH%;%OSG_SAMPLES_PATH%;C:\WINDOWS\system32\WindowsPowerShell\v1.0;C:\Program Files\IDS\uEye\GenICam\bin\win32_i86; C:\Program Files\OpenCv\bin;C:\Program Files\CMake 2.8\bin;   C:\OpenCV2.0\VS2005\bin\debug; C:\OpenCV2.0\VS2005\bin\release; C:\OPenCv2.0\bin

I guess its possible the OpenCV2.0 installation I have is interfereing somehow with the OpenCV 1.0 download?

[JimC]

In your script (or at the Vizard Python prompt) type:

import sys
print sys.path

That will tell you where it's looking for modules.

[JimC]

Never mind. I tried it myself and got the same error. When I copied the dlls into the site-packages/opencv directory it went away.

[sircedric4]

Sweet! Thanks a lot. That did the trick. Now I can play with some of these OpenCV functions.

I just got finished trying the capture-cam.py example and got a runtime error. When I ran it, it first prompted me to select a web camera and then when it tried to run it gave the following error:

Microsoft Visual C++ Runtime Library
Runtime Error!

Program: C:\program files\WorldViz\Vizard31\bin\winviz.exe

This application has requested the Runtime to terminate it in an unusual way.  Please contact the application's support team for more information.

I would like to marry the capturing of a video camera with the square detection of squares.py. Does anyone know what runtime error it is running into. It looks like it is getting hung up on:

# get size of the frame
    frame_size = cv.cvGetSize (frame)
