摘要：When LIDAR data is considered as data source for 3D models of urban areas, there is the choice between airborne and terrestrial systems. They have different characteristics like resolution or scene extent. One of the most significant differences is that city models from airborne scanners typically lack any facade structures. It seems natural to combine both types of LIDAR data for better results. The key to this type of data fusion is a successful registration, i. e. the geometric transform of one data set into the coordinate frame of the other. This paper proposes a method that is based on feature lines that are extracted in a similar way from both data sets. The emphasis is on the coarse registration – the estimation of initial transformation parameters without any prior knowledge
