Research on Real Estate Geographic Information Acquisition Method Based on Remote Sensing Image
The existing methods for collecting real estate geographic information are difficult to accurately divide the boundaries of real es-tate,resulting in significant errors in the results of real estate geographic information collection.Therefore,a real estate geographic information collection method based on remote sensing images is proposed.Based on the angular second-order moment parameters and correlation,the fea-ture parameters of remote sensing images are extracted,and the boundary information of each real estate within the collection range is divided according to them.By matching the position of the target real estate pixel within the spatial dimension grid range of the remote sensing image,the collection of its geographic information is achieved.The test results show that the average Kappa coefficient of the design method is 0.687,and the accuracy of image information collection is above 97%.The results of real estate geographic information collection are basically con-sistent with the actual information,and there is no missing situation.Therefore,it indicates that the proposed geographic information collection method can reduce the collection error.
