Abstract
Aircraft manufacturers integrate a lot of equipment from different suppliers and on some occasion this equipment are like black boxes, the only easy way to check the data is through special monitoring displays supplied with the equipment. On other occasions a real aircraft display needs to be validated. These displays can be very complex, big amount of symbols and very dynamics. The validation of these displays can be a very tedious work if it is done by hand.
This document presents a methodology to automate the validation of the aircraft displays based on image processing to extract numbers, texts and symbols. These displays are not completely standards in the market and they have not been created taking into account these image processing techniques, so it is almost impossible to develop a generic tool. A specific tool will be developed for each display but they will share common stages from the specific pipeline.
There is a lot of literature about image processing but what it is really important is the definition of the pipeline in order to have a robust and efficient data acquisition system based on image processing. This document will give an overview of the different stages and some pipelines applied in real use cases in Flight Test Airbus Defence and Space.
