Geometric modelling of 3D laser cameras for biomedical applications

The next generation of three-dimensional (3D) imaging systems, laser range cameras (LRCs), offer great potential for biomedical engineering applications that demand highly accurate 3D data for constructing analytical models of the human body. Unlike current technologies used in biomedical applications, such as digital cameras, laser scanners and X-rays, an LRC rapidly captures full scenes of 3D data with only a single, low-cost camera and without exposing the subject to harmful radiation or the need for multiple, expensive sensors. Due to the recent commercial availability of LRCs, the data processing methods needed for 3D biomedical applications requiring high accuracy are either in their infancy or non-existent. The principal aims of this research project are therefore to enhance the metric potential of this technology by developing and experimentally validating the necessary mathematical models and associated algorithms. The outcomes will be implemented in software that is highly likely to attract commercial interest in Canada and overseas. Furthermore, the project will train numerous highly qualified personnel who will be international experts in this frontier technology. Biomedical applications that will benefit include cranio-facial scanning, scoliosis mapping and full human body measurement.
