Abstract
A method and a hybrid 3D-imaging device for surveying of a city scape for creation of a 3D city model. According to the invention, lidar data is acquired simultaneously with the acquisition of imaging data for stereoscopic imaging, i.e. acquisition of imaging and lidar data in one go during the same measuring process. The lidar data is combined with the imaging data for generating a 3D point cloud for extraction of a 3D city model, wherein the lidar data is used for compensating and addressing particular problem areas of generic stereoscopic image processing, in particular areas with unfavourable lighting conditions and areas where the accuracy and efficiency of stereoscopic point matching and point extraction is strongly reduced.
