US Patent 9142019 System for 2D/3D spatial feature processing

An electronic device (100) includes a first processor (802) and a second processor (804) coupled to the first processor. The first processor (802) is to receive image data from a first imaging camera (114, 116) and to determine two-dimensional (2D) spatial feature data representing one or more 2D spatial features identified from the image data. The second processor (804) is to determine three-dimensional (3D) spatial feature data representing one or more 3D spatial features identified based on the 2D spatial feature data. Further, the first processor (802) can initiate detection of one or more 2D spatial features from a portion of an image frame prior to receiving the entire image frame.
