基于Roberts边缘检测的面向对象建筑物信息提取

摘要

It is cockamamie and complex to confirm the segmentation scale in extracting process of the object-oriented buildings.This paper proposes an estimated method of segmentation scale based on the Roberts edge detection.We get the edge image by using Roberts detection and choose samples to calculate the values of parameters,so as to determine the optimal partition scale.Experiments show that this method is simple.It can determine the optimal partition scale parameter rapidly.It also improves the efficiency of buildings＇ extraction and its precision is higher.%面向对象的建筑物提取过程中确定分割尺度繁琐而复杂。本文提出了一种基于Roberts边缘检测的分割尺度估算方法,利用Roberts检测得到边缘影像并选取样本计算出参数估值,从而确定最优分割尺度。实验表明,该方法实现过程简单,能快速地确定最优分割尺度参数,提高了建筑物提取的效率且精度高。
