Ok, i'm experiment with opencv and this what i got:
1) I installed OpenCV-2.2.0-win32-vs2010.exe from the opecv site and i choose to install the system variables for all users. 2) I installed numpy-1.5.1-win32-superpack-python2.7.exe (because it seems that opecv need it) 3) I copy the files of C:\OpenCV2.2\Python2.7\Lib\site-packages to C:\Program Files (x86)\WorldViz\Vizard4\bin\lib\site-packages 4) i tried this code in vizard and it WORKS!!!: Code:
import cv cv.NamedWindow("camera", 1) capture = cv.CaptureFromCAM(0) while True: img = cv.QueryFrame(capture) cv.ShowImage("camera", img) if cv.WaitKey(10) == 27: break cv.DestroyWindow("camera") Code:
import Image import cv import viz viz.go() def PIL_TO_VIZARD(image,texture): """Copy the PIL image to the Vizard texture""" im = image.transpose(Image.FLIP_TOP_BOTTOM) texture.setImageData(im.convert('RGB').tostring(),im.size) capture = cv.CaptureFromCAM(-1)#conectate a camara tex = viz.addBlankTexture([1,1]) quad = viz.addTexQuad(pos=(0,1.8,2),texture = tex) while True: src = cv.QueryFrame(capture) dst = cv.CreateImage(cv.GetSize(src),cv.IPL_DEPTH_8U,1) cv.CvtColor( src, dst, cv.CV_RGB2GRAY) #Convierto opencv to PIL image pil = Image.fromstring("L", cv.GetSize(dst), dst.tostring()) #Aply image to texture PIL_TO_VIZARD(pil,tex) if cv.WaitKey(10) == 27: break If anyone has a clue of what maybe is happening |

Hi DarkMax,
Just wondering if you had any luck with this? All I get when is a black screen in the cvWindow instead of the stream from the webcam, most other samples from OpenCV seem to work although I haven't tried them all. This would be a total game changer for me if Viz 4 and OpenCV can be made to play well together . . . . . . . |

Some that know why i can pass the image from the camera to a plane in vizard?

I resolve the problem, now i have opencv and vizard working together, just i have to use the viztask.schedule() command on the method that i use for opencv

Hi Darkmax,
Thats fantastic news, I'm still struggling to get openov to play nicely with Vizard, am even thinking of trying with pyopencv when I get a chance (writing writing writing at the moment ![]() However, would it be possible for you to give me some advise as to how you have managed to get them working with each other, just a few pointers to get me started - I can use opencv with the highgui window, but am getting stuck trying to pass the video frames to the vizard render window ![]() ![]() Any advise would be really welcome, best regards |

try this code:
Code:
import Image import cv import viz import viztask #Quad to display the image on vizard tex = viz.addBlankTexture([1,1]) quad = viz.addTexQuad(pos=(0,1.8,2),texture = tex) def PIL_TO_VIZARD(image,texture): """Copy the PIL image to the Vizard texture""" im = image.transpose(Image.FLIP_TOP_BOTTOM) texture.setImageData(im.convert('RGB').tostring(),im.size) def opencvMain(): capture = cv.CaptureFromCAM(-1)#conect to a camera while True: src = cv.QueryFrame(capture) #Image from camera in BGR format dst = cv.CreateImage(cv.GetSize(src),cv.IPL_DEPTH_8U,3) cv.CvtColor( src, dst, cv.CV_BGR2RGB) #Converting BGR to RGB #Converting opencv image to PIL image pil = Image.fromstring("RGB", cv.GetSize(dst), dst.tostring()) #Aply image to texture PIL_TO_VIZARD(pil,tex) cv.WaitKey(10) yield viztask.waitTime(0) viztask.schedule(opencvMain()) viz.go() |
