Bypass Vuforia's handling of the camera image and pose

问题:

I want to bypass Vuforia's display handling of the camera image and pose of framemarkers on iOS, is this possible?

回答1:

In - (void)QCAR_onUpdate:(QCAR::State *)state you can grab the camera data and the marker poses.

Camera image data

QCAR::Frame frame = state->getFrame();  for (int i = 0; i < frame.getNumImages(); i++) {     const QCAR::Image *image = frame.getImage(i);     if (image->getFormat() == kQCARFrameFormat) {          const void *pixelData = image->getPixels();         int width = image->getWidth();         int height = image->getHeight();      } }

Marker poses

NSMutableArray *mutableFramemarkers = [[NSMutableArray alloc] initWithCapacity:state->getNumTrackableResults()]; for (int i = 0; i < state->getNumTrackableResults(); i++) {     const QCAR::TrackableResult *trackableResult = state->getTrackableResult(i);     const QCAR::MarkerResult *markerResult = static_cast<const    QCAR::MarkerResult *>(trackableResult);     const QCAR::Marker &marker = markerResult->getTrackable();     QCAR::Matrix44F qcarPose = QCAR::Tool::convertPose2GLMatrix(trackableResult->getPose()); }
