摘要
在对田坎系数的理论基础进行简述后,提出了田坎系数获取的两种途径:传统意义上的量测获取和影像分类原理的田坎系数获取。最后得出结论:基于影像分类原理的田坎系数获取具有一定的科学性且与实地测算的田坎系数具有较高的符合度,可作为实地测算的补充手段。
After brief descriptionIn of theoretical basis for field threshold coefficients,this paper presented two methods for Obtaining Field Threshold Coefficient:one is traditional sense of measurement,the other is image classification principles.Finally,we get conclusion:on the base of the image classification principles,the coefficient obtaining way is a certain scientific method with a high coefficient and it can be used as a supplementary means of measuring the field.
