Abstract: Field road is an important project for farmland construction and management,and its direction,width and accessibility directly affect the convenience of farmland cultivation.Therefore,accurate identification of field road is of great significance for evaluation of farmland construction effect.With the help of high-resolution images,this paper adopts object-oriented method to identify the road based on the idea of hierarchical classification.Then,tensor voting method,eight-neighborhood breakpoint detection and morphological algorithm are introduced to repair the breakpoints.Take Dingzhou city,Hebei province as an example,the result of field road recognition is obtained,and the integrity rate,accuracy rate and quality of field road identification are 91%,74% and 69%,respectively.

Key words: high-resolution image, field road, recognition method, object-orientation, breakpoint detect
