Abstract
A method and system is provided for automatic generation and navigation of optimal views of facades of 3D building models in an interactive three-dimensional (3D) map system. The system and method allows for navigation and visualization of facades of building models in a 3D building model visualization system through optimal views of facades.
Claims20
A method of visualizing a 3D building model, the method comprising:
- retrieving one or more 3D building models;
- defining a look angle and field of view for the retrieved one or more 3D building models;
- calculating a first main axis and a second main axis for the one or more retrieved 3D building models.
- calculating an optimal camera position for the one or more retrieved 3D building models based on the defined look angle and calculated first main axis and second main axis;
- and
- generating an optimal view for the one or more retrieved 3D building models based on the calculated optimal camera position and the field of view.
3 more elements
A system for visualizing a 3D building model, the system comprising:
- a view processor for processing an optimal view of one or more selected 3D building models, the processing comprising:
- defining a look angle and field of view for the selected one or more 3D building models;
- calculating a first main axis and a second main axis for the one or more selected 3D building models.
- calculating an optimal camera position for the one or more selected 3D building models based on the defined look angle, field of view and calculated first main axis and second main axis;
- and
- generating an optimal view for the one or more selected 3D building models based on the calculated optimal camera position and the field of view.
3 more elements
A method of navigating a 3D image including one or more 3D building models, the method comprising:
- selecting at least one of the one or more 3D building models from a 3D building model visualization system;
- retrieving one or more optimal views of the selected at least one of the one or more 3D building models as fixed perspective views;
- and
- navigating within the 3D image between the fixed perspective views.
