万方数据 万方数据 Subject: The Study of Extraction Method based on Countryside Plowland Boundary of Remote Sensing Images Specialty: Cartography and Geographic Information System Name: Hu Rui Qi （Signature） Instructor: Chen Xiao Ning （Signature） Abstract Third Plenary Session of the Partys Eighteen decision clear the orientation and task of rural land reform. In the recent years, the central government from safeguarding the legitimate rights and interests of farmers and rural social harmony and stability of the height, clear put forward the objectives and task of the rural land ownership. Since 2010, the street of four different types of pilot counties, towns were selected trial plot,like GaoLin county, Xiao Jin viliage, Lin Tong village Xiang Qiao street, Ren Zong street of shaanxi province,develop rural property rights system reform pilot work.This paper chooses Shen Dong village Xiang Qiao street village as a study of the test area.The study of cultivated land boundary extraction method based on remote sensing image has a strong practical significance; to find a method for automatic extraction of cultivated land boundary,and to use land boundary map to assist complete rural land ownership and other related work to achieve lower costs,shorten the working period and other practical problems. Considering that the countryside plowland of necessity in combine with own research need, such research project is put forward. Such article mainly in respect of methods to extract the plowland boundary information states as follows in detail, including edge inspection methods for Roberts operator, Sobel operator, Prewitt operator, Laplace operator, LOG operator and Canny operator, makes the particular theoretical statement correspondingly for each kind of the concerned operator and experiment emulation in the plowland at two experimental zones which are respectively located in the highland and plain, proceeds the analysisand comparison for the edge inspection results of t
