Soluzioni IT The SMF/SIGN is the instrument for the in-field real-time assessment of Vertical Guidance Signs, able to perform all the measurements recommended by ICAO Annex 14 using a fast, friendly and affordable procedure. The easy use of SMF/SIGN allows to collect the pictures of all the vertical signs installed in a big airport in just one night. The operator can ask for the instant processing of current sign or to collect all the images first to be later processed in a single session. The built-in system database allows the maintenance team to get and store all the photometric data for each Vertical Guidance Sign installed in the Airport. SMF/SIGN makes now possible to apply the full set of ICAO recommendations for SIGNS due to the powerful image analysis software which allows to measure the Luminance, Luminance ratios, Colors, Letter and Numbers dimensions, Color Ratios, Dimensional ratios, etc. All images collected may be easily analyzed using the system Laptop just in the maintenance vehicle or more comfortably in AGL maintenance office. A complete automatic reporting is provided by SMF/SIGN to be saved or printed at the end of image analysis processing. DATABASE The system database has the capacity to store all the data relevant to measurements performed during the instrument lifetime. The database stores information of Countries, Airports, SIGN brands and models, measurement results, graphics, pictures and statistical data. REPORTING • False color image of the Sign luminance, with a resolution of 1 mm • Color map image of ICAO admitted colors (white, red, yellow, black, green, blue, orange, yellowish-green), with 1 mm resolution • Average Luminance for each Sign color, calculated both over the standard ICAO grid and on each pixel of the instrument camera • Chromaticity for each color, on the grid and on each image pixel (CIE x, y) • Luminance Ratio between adjacent points on the grid for each color. • Luminance Ratio between maximum and minimum values points on the grid for each color. • Luminance Ratio of red color to the white. • Dimensional Ratio of characters fonts to the Sign. • Automatic localization of the ICAO grid, for both background and characters FAST TESTING The system allows the maintenance team to test all the vertical guidance signs in the airport in one single night, by taking pictures shots of each installed sign. • Complete Photometric Analysis of any type of Vertical Sign according to ICAO Annex 14 recommendations • Fast measurements procedures with instant feedback or post-processing analysis • LED illuminated Signs supported • Light Intensity according to ICAO Annex 14 reference grid points • Color Measurement according to CIE 1931 • Quick feedback for real-time maintenance • Full Automatic PDF and Excel reporting SMF / SIGN Photometric Instrument for AIRPORT GUIDANCE SIGNS
