A location sensor(40) detects positional information for the image acquisition means when capturing the plurality of images 0 comprising the image streams. An image processor(30) coupled to the image acquisition and the location sensor(40) processes the Il image stream of a light of the airfield ground lighting system by: (a)associating characteristics of a plurality of points in an image with 1-1 --.... an item in the light to be checked, and using this association for extraction of the points; (b)each extracted point is verified; and (c) the * 1 : state of the light of the image stream is determined by processing the verified extracted points comprising an item to be checked. 1-1 0 ei O [Continued on next page] WO 2018/116032 Al MIDEDIMOMOIDEIREE31011110011100101BER KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
