| 摘 要： | 基于eCognition的多尺度影像分割与识别技术,进行了土地变化监测研究。首先选取同一区域不同时相的两幅影像,通过实验确定适宜变化监测的尺度参数、形状参数和紧致度参数,然后进行影像分割,最后进行各类地物信息提取,探测不同时相同一地物的不同形态,进而发现地类图斑变化。实验表明,基于eCognition,可以分析出地类图斑的细致变化,完成土地动态监测。通过对比实测数据,基于eCognition的地类图斑点识别精度合格率在90%以上,不失为一种高精度土地动态监测新方法,同时也为土地变化信息监测提供了一种经济、科学的技术方案。

Application of eCognition in Land Dynamic Monitoring |

| Abstract: | Based on Multi-scale image segmentation and recognition technology of eCognition,this paper has carried on the research of land change monitoring.Firstly,two images of the same area but different time were selected,the suitable parameters of scale parameter,shape parameter and compactness parameter were determined by experiments,then the image was segmented,at last,all kinds of feature information was extracted by detecting different forms of the same object,thus the land patch changes were found.The experiment shows that detailed patch changes was distinguished based on eCognition,so land dynamic monitoring was completed.By comparing the measured data,the accuracy rate of patch recognition based on eCognition is more than 90％,it is a new method for high precision dynamic monitoring of land,and it also provides a technical and scientific scheme of change information monitoring of land use. |
