摘　　要：本文以光学成像原理为基础,通过实测、三维模拟测量的方式取得成像参数,证明了成像照片中地物的固定比例特性,以此构建坐标矩阵模型实现标准化测量;通过对照片测量点建立1000m缓冲区与冬小麦遥感测量结果进行回归分析,1000m格网的遥感测量结果为当年统计调查结果的99.5%。本文构建的模型,解决了手机拍摄取得照片的标准化测量问题,拓宽了农作物面积测量野外数据获取方式,提升了农作物遥感应用能力。Based on optical imaging principle, the paper got imaging parameters by actual measurement and simulated photos created by 3D software and found that objects on photos have fixed ratio properties. Then we established the coordinate matrix model to realize standardized measurement. We expanded the data to 1000m buffer areas from every photo＇ s measuring point, and made regression analysis with the data of same buffer areas achieved by RS model. The result based on RS measurement for all the 1000m grid of Yuanshi county is 99. 5% of the official statistic result. In this article we established a model which could figure out the standardized measurement by photos taken by mobile phone. The study gives the surveyors new survey method to get field data for crop area measurement and promotes remote sensing application in agricultural survey.
