The invention relates to photogrammetric area, in particular to methods for decoding images. Method for determination of location of flash of single shot is in survey of locality at day time from two points of photo-theodolite basis with digital theodolite, transfer of image to digital photogrammetric station, compilation of stereo-model of locality and development of system of spatial coordinates. After that at day time one performs periodic survey from one point of photo-theodolite basis with fixation of flash of single shot, one transfers it to digital photogrammetric station with determination of coordinates by stereo-pair of day images on one of which single shot is fixed. According to the invention shooting from one point of photo-theodolite basis and fixation of single shot are carried out at dark time as well, and before determination of coordinates ot place of flash for single shot one identifies location of shot on day image obtained from that very point with marking it with conventional sign. The invention makes it possible to determine effectively and unambiguously on surface photo-theodolite shot place of flash of single shot (blast) without guarantee of repetition, for that having take place at dark time of day, with increase of accuracy and reliability of determination of qualitative and quantitative characteristics (coordinates, type of object, arms, and others). |
