CODED TARGET AND PHOTOGRAMMETRY METHOD USING SUCH TARGETS

摘要

The invention relates to a coded target which is used in photogrammetry. According to the invention, the coded target is circular and consists of at least two concentric coding rings comprising at least two equal angular sections which are disposed around a central area. Said central area comprises a central, homogeneously-coloured disk which is surrounded by a complementarily-coloured ring which is, in turn, surrounded by a ring of the same colour as the central disk. The invention also relates to a photogrammetry method which can be used for the automatic detection and identification of such targets.
