Abstract

Superficie plana o tridimensional, a modo de placa de calibración, que se caracteriza porque sobre ella se han dibujado con precisión un conjunto de marcadores fiduciarios de distinto tamaño, que no se solapan y cuya posición relativa sobre la superficie es conocida con gran exactitud. Opcionalmente, los marcadores fiduciarios tienen forma de cuadriculas regulares compuestas de celdas cuadradas que están coloreadas en dos tonos de diferente luminosidad, tienen el mismo número de filas y columnas, pero distinto tamaño de celda.Flat or three-dimensional surface, like a calibration plate, characterized in that a set of fiduciary markers of different sizes, which do not overlap and whose relative position on the surface is known with great accuracy, have been accurately drawn on it. Optionally, the fiduciary markers are in the form of regular grids made up of square cells that are colored in two shades of different luminosity, have the same number of rows and columns, but different cell sizes.
