CAMERA: CAd Modelling of Built Environments from Range Analysis

PROJECT OBJECTIVES

The scientific objectives of the project are to investigate:

• methods for construction of finite and unbounded (ie. without the natural closure of individual objects) CAD models of built environments including both interiors and exteriors.
• methods for extraction and incremental fusion of typical environmental features (eg. pipes, walls, floors).
• how to fuse sparse, but continuously tracked shape, obtained from projective geometrical analysis of intensity images with dense shape obtained from single range images.
• how to plan for incremental sensing for extending and filling out models.
• how to exploit constraints typical of built environments (eg. systematic rectangularity and parallel features) or typical architectural structures (eg. doorways) to improve model accuracy.
• how to link locally accurate models (eg. of individual rooms) to form accurate global descriptions of the environment (eg. by exploiting constraints arising from two rooms being adjacent across a wall).
• how modules implementing the research results might be integrated together in a usable system.

The training objectives of the project are:

• develop cross-disciplinary skills in computer vision, computer graphics, computer-aided design, sensor navigation and fusion and photogrammetry.
• provide post-doctoral researchers with broader project perspectives, trans-national experience and experience in a commercial organisation.
• provide a forum for idea exchange and accelerated progress in a new and rapidly developing research area.
