Python IMAQdxGrab Examples

Example #1

File: NI_camera.py Project: sss441803/DNN-SLM--optics

def capture():
   nivision.IMAQdxGrab(id, img, 1)
   picture = nivision.imaqImageToArray(img)
   data = struct.unpack(fmt, picture[0])
   data = np.asarray(data)
   data = np.reshape(data, (cam_y, cam_x))
   return data

Example #2

File: usbcamera.py Project: xortive/robotpy-wpilib

    def getImage(self, image):
        with self.mutex:
            if self.needSettingsUpdate or self.useJpeg:
                self.needSettingsUpdate = False
                self.useJpeg = False
                self.updateSettings()

            #t0 = time.time()
            nivision.IMAQdxGrab(self.id, image, 1)

Example #3

 def grab(self, waitForNextBuffer=True):
     nv.IMAQdxGrab(self.imaqdx,
                   self.img,
                   waitForNextBuffer=waitForNextBuffer)
     return self._decode_image_data(self.img)
