一个基于人计算的土地确权地块边界提取系统

A System for Land Block Extraction Based on Human Computation

当前我国正在进行大规模的农村土地确权,大部分地方采用了基于航飞DOM影像来对地块空间位置进行确定。但是,受当前影像处理算法智能程度的限制,需要大量专业人员来提取影像中的地块边界,导致成本和时间开销的增加。本章将人计算(human computation)理念引入影像处理,设计了一个基于人计算的土地确权遥感影像地块边界提取判读应用系统,实现了系统原型,验证了其可行性。

Our country is establishing rural land-use rights on large scale,and most areas are utilizing the DOM-based image to determine the spatial location of land. However, due to the limitation of the current image processing algorithms, a large number of professionals are required to extract the block boundaries in the image, which leads to the increase of the cost and time. This paper proposes to lead human computation in image processing,which allows a remote sensing image system for land block extraction based on human computation is designed. Thus, the system prototype is realized and the feasibility of the system is verified.
