HOU Qi-zhen1, YANG Bo-en2. Design of optical axis detecting system of airport navigation lights[J]. 2013, 32(2): 77-80. DOI: 10.13873/j.1000-97872013.02.014.
Considering the requirements of domestic airport navigation maintenance
existing problems and light-emitting characteristics
a design of optical axis detecting system of navigation light based on FPGA and CCD is proposed.Combination of FPGA and CCD is one of the features of this system
and key techniques are discussed emphatically
including selection of system sensor
modular design of FPGA and PCI bus transmission technology.System calibration is carried out
and the collected datas are processed by centroid algorithm.By detecting offline lamps in the laboratory
