The BEAM project seeks to advance the state of the art of autonomous devices that can perceive and intelligently respond to their environment. The overall aim of the project is to develop a device capable of assessing lighting systems used within transportation, with particular reference to aviation.
The novel device will consist of cameras placed inside an aircraft and used to collect images of an airfield landing lighting pattern (see Figure 1) during a normal approach and touchdown. Image processing algorithms can be applied to the collected images in order to extract and track individual luminaries. The system will then be able to determine if the lighting pattern conforms to standards (see Figure 2) and this information can be relayed to the airport authorities.
Today’s improved low cost information and communication technology makes it possible to develop an intelligent inspection system for airport landing lighting control that records information with a number of cameras and sensors. The system we propose will use vision sensors capable of recording high-resolution visual information at high inspections speed. The vision data will be stored on hard disk together with data from various other sensors to determine the exact location of the recording and to be able to synchronise all data in time and place.
The system we propose differs radically from anything currently being researched. We consider the integration of a number of sensing technologies to optimise the system performance. The measurement system is dynamic and can manoeuvre with six degrees of freedom which is vital for the airport lighting application.
To satisfy the aims of this project, a number of scientific and technological objectives have been defined:
- To set up laboratory based test facilities such that the vision sensors may be characterised in a precisely controlled and reproducible manner.
- To construct regional, European and Worldwide databases detailing the airfield lighting layout and dimensional information.
- To specify, develop and implement technologies for airport lighting assessment and management.
- To investigate and specify how to interface and integrate a range of sensing technologies for data collection to a user friendly intelligent diagnostics system.
- To interface and integrate the novel system into existing aircraft
- To produce recommendations and guidelines for the generic adoption of BEAM by standards bodies.
- To assess the commercial feasibility of BEAM through demonstration and teaching systems
- To produce a tool that in principle is transferable between other transportation channels e.g. road lighting, rail signal lighting.
- To engage European stakeholders in
- a continued dialogue on the evolution of the research,
- disseminating the research results,
- defining the agenda and needs for future research and policy development.
The overall success of this research project will be measured by the completion of these scientific and technical objectives.
Thus the BEAM project brings to the study of airfield lighting an innovative and novel research methodology, with the objective of identifying potential failures within the airport landing lighting pattern.
