Title: MICRO-LOCALISATION METHOD AND DEVICE FOR AN IMAGING INSTRUMENT AND A MEASURING APPARATUS
Abstract:
The invention relates to a micro-locatlisation device (100) defining a system of spatial coordinates for an imaging instrument. According to the invention, the micro-locatlisation device (100) includes at least one first zone (1) and one second zone (2) that are adjacent, each zone (1, 2) extending spatially over an area of macroscopic size, each zone (1, 2) comprising an elementary cell (11) or tiling of a plurality of elementary cells (21, 22, 23, 24) extending over the respective area of said zone (1, 2), each elementary cell (11, 21, 22, 23, 24) of the first and second zones (1, 2) respectively comprising an orienting pattern (1111, 2111), a positioning pattern (1112, 2112, 2212, 2312, 2412) and a periodic spatial pattern (112, 113, 212, 213, 222, 223, 232, 233, 242, 243) that are configured to be imaged by an imaging instrument and to allow a position and orientation of the imaging instrument to respectively be determined in the system of spatial coordinates of the micro-locatlisation device.
