摘要：In order to supervise and manage building change in urban development, unmanned airship is recommended for building change. With the unmanned airship, lower flying height can be obtained. As a result, high resolution aerial image can be acquired. And then, auto-aerial triangulation are easily applied to images so that product efficiency is greatly improved. And also, DSMs can also be quickly get. Width DSMs from different times in short period, building changes can be figured out by differential between DSMs
