Abstract: Aiming at the shortcoming of target recognition technology based on global features, this paper introduces target recognition technology based on local feature. The main component parts and the merits of the technology are introduced briefly. And the local features are divided into three classes and some approaches in common use are explored. From the point of applications, the difficulties of target recognition are discussed. The development trend of the area is forecasted.

Key words: target recognition, local feature, corner pointer
