Qt Camera Class with generating signal of image reception for Spinnaker FLIR camera
Qt Camera Class with generating signal of image reception for Spinnaker FLIR camera. Which is possible by connection Qt Signal object to image event handler of Spinnaker library. It makes speed up frame per second, and reduce down effort of polling routine to receive and provide image through Spinnaker object. It supports both of Qt and PyQt5, which are named as qt_camera, and pyqt_camera, respectively.
Method
There are three kinds of ways for triggering the camera hardware. The default is No triggering that no need to provide any trigger, and can access streaming images at any time. The second is the Software Trigger, in which an image is available after 'sendSwTrigger()' was excecuted. The last is the Hardware Trigger. The camera provides an image via Qt Signal, only if electrical PWM is connected to specific input ports of external Hirose Connector.
How to use
qcamera.initSystem()
cam = QCamera()
cam.sendImage.connect(onReceiveImage) cam.enableAcquisition()
...
cam.disableAcquisition() del cam
...
@QtCore.pyqtSlot(np.ndarray, int, str)
def onReceiveImage(image, image_count, camera_serial):
#doing something related to image processing
pass
