| Abstract: | This paper chooses buildings A and B in a certain area of Chengdu as the research objects.Quick bird image with resolution of 0.61m is used.Image segmentation and LVQ neural network algorithm are used to extract side information of building.According to the principle of hypothesis method,a physical model of height calculation is constructed to calculate the height of building.By comparing the measured data,combining with the factors that may affect the experimental results and remote sensing image,the accuracy analysis and evaluation are carried out,and the methods of building side information extraction and height calculation based on high-resolution remote sensing image are discussed.The results show that LVQ neural network algorithm has better application value in building side extraction and height calculation,and the accuracy is as high as 94%. |
