The ground-based photometric observations of asteroids still is the main source to understand their basic physical properties, even though some space mission and space-based instruments have been applied in physical studies of asteroids. Owing to developments on scattering theories and 3D shape models of asteroid, we can carry out determination for basic physical parameters of asteroids from the photometric data. Here, we present photometric observations for some selected asteroids and light inversion results for these asteroids. In detail, they are: (1) To determine photometric phase functions of asteroids (107)Camilla and (106) Dione considering an ellipsoid shape and a cellinoid shape respectively; and (2) To inverse convex shape of main-belt slow rotating asteroids (168) Sibylla and (346)Hermentaria and a near Earth asteroid (3200) Phaethon. Based on derived photometric phase functions, the geometric albedo, and even rough taxonomic classification of asteroids are inferred. With the virtual photometry Monta Carlo method, the uncertainties of spin parameters of selected asteroids were compared.
