This paper introduces a block adjustment method of airborne InSAR images based on 3D model. It provides an efficient way to geocod DEMs as well as grey scale images. This new method requires few GCPs (ground control points) which are difficult to measure in mountain area. As a result, it saves a lot of manpower, financial power and material resources in the process of cartography. The new method was successfully used on InSAR images acquired over Shanxi area (Midwest of China). The experimental results show that the block adjustment based on 3D model could reach the same level of accuracy as the approach of rectifying each single image separately. The later requires a large number of GCPs.

This article mainly describe that using non-metric digital camera, through taking photos of mine surface ,based on the theory of close-range photographic, coordinates of the surface is obtained. According to the coordinates, 3D model of mine surface is built. The large scale maps of mine are made. Based on coordinates and 3D model in the period of different time, the changes of mine surface are get. Changes measured can know the shape of mine in time and test the reasonableness of eye position of mine explore and make adjustments based on the data.
