We present the measurements of 49 visual double stars made in 1997 with the 50 cm refractor of the Nice Observatory (Table 1). A CCD camera was attached to this refractor. Some new binaries discovered by Hipparcos have been measured. The algorithm used for these measurements is based on the adjustment of a tridimensional mathematical surface.

Key words: astrometry -- binaries: visual
