In view of this situation, in this paper, the basic content of the recognition of crop pests image were studied. Firstly, two ways of acquiring the pest images have been discussed and compared; Secondly, preprocesses of these images have been studied and experimented, including image graying as well as image enhancement; Finally, seven principles and steps have been proposed to construct the pest image set.
