Abstract :
Many nonmodernized aircraft lack the ability to capture, in a computer readable medium, information related to cockpit display instruments, such as airspeed indicators and barometric altimeters. Most of these old cockpit instruments consist of a mechanical or pneumatically operated analog device without an electronic interface. In this work, we present a new video to information (V2I) system to enable these old instruments to output digital readouts by using a camera system and embodiments of image processing algorithms to interpret video data streams. A camera system is trained across the instruments and captures image frames. An image processing system then extracts graphical symbols such as needle position, alphanumeric readout, bar position, color, and similar informative cues. The data are then interpreted and information is extracted, recorded and transmitted to a responsive system, which may then act upon the data as desired for data collection and analysis.
