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());
}
