QTSculptor Specifications

The QTSculptor program consists of a base module and optional program components for the control of the 3D sensor and the texturing of the 3D model.
All components are integrated in a user interface for ease of operation, but can also be used separately.

• Base module
  The base module forms the framework of the system. It contains all functionality with which the acquired 3D views are processed and brought together to form the complete object geometry.
  The essential functions are:
  • Import/Export functions
  • Interactive view planning
  • Easy handling of large datasets consisting of many range images
  • Segmentation of the range images
  • Registration/Orientation of range images into a common world coordinate system
  • Filtering functions
  • Utilization of data redundancy for improved precision
  • Polygonization
  • 3D visualization
  • Editing functions for the mesh

   

• Texturing module
  The texturing module allows for the production of 3D photo-realistic models and for their export as VRML models.The texturing is carried out using additionally acquired photographs of the object.
  The object is photographed with a digital camera from arbitrary viewpoints under constant lighting conditions.The resulting pictures are read into QTSculptor and with a few mouse clicks the system calculates the position of the camera with respect to the object.
  An automatic optimization algorithm makes sure that the photographs fit the geometry and to each other in overlapping areas. The photographs are combined and a textured 3D model is produced.
  • Processing of texturing photographs
  • Registration of the photographs in the object coordinate system
  • Calculation of the textured 3D model
