Abstract

The invention belongs to the technical field of three-dimensional modeling, and discloses a novel city three-dimensional modeling control system and method. The system comprises an image input unit, acamera calibration unit, a parallel moving and rotating data input unit, a digital elevation model input unit, a landscape model generation unit, a texture extraction unit, an architectural model generation unit, an architecture model storage unit, a model matching unit and a display unit. According to the system, by using the digital elevation model (DEM) and images acquired from an aerial vehicle and the ground, modeling of three-dimensional appearance of city architectures and three-dimensional landscape is achieved, and realistic textures are extracted from the images; three-dimensional architecture models can be generated by using the images taken from the air in vertical and inclined directions except for the DEM, textures of the related three-dimensional models can be extracted, the three-dimensional models generated by the images acquired from the ground can be simulated more accurately, or the textures with higher definition can be extracted.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional modeling, and in particular relates to a novel urban three-dimensional modeling control system and method. Background technique [0002] Mapping services and ultra-high-speed Internet transmissions using high-resolution satellite imagery have become widely available. In addition, road view or street view type services using images captured on the ground are attracting attention as a new type of service. Map services that use satellite imagery can label buildings or road names on satellite imagery of the area the user expects to see, so it is sometimes possible to search for a route given a source and destination. In addition, map services enable users on the ground to upload images taken in relevant areas to servers, and to view weather and satellite images of the area even with ground images. At the same time, such a map service also enables the sharing of 3D models made by users them...
