Abstract The CCD image scanning measuring system can obtain accurate and comprehensive precipitation particle information with features of simple structure, easy detection and high precision. The structure of this system is introduced briefly. Based on a typical image scanning detector, the theory of precipitation particle detection in this system is described in detail. Then, the potential errors in practical application are discussed. Meanwhile,the key technology of the CCD image scanning detection system is analyzed.
