• ALFaceTrackerProxy::setWholeBodyOn()
• ALFaceTrackerProxy::startTracker()
• ALFaceTrackerProxy::stopTracker()

Methods

std::vector<float> ALFaceTrackerProxy::getPosition()

Deprecated since version 1.16: use ALTracker module instead.

Returns the [x, y, z] position of the face in FRAME_TORSO. This is done assuming an average face size, so it might not be very accurate. This invalidates the isNewData field of the tracker. See ALFaceTrackerProxy::isNewData() for more details.
