Abstract

The project is divided into four phases. Phase 1: Enhancement and commercialization of single moire scanner A single moire scanner for capturing the human leg has been developed in our laboratory. To commercialize this novel product, the hardware will be packaged with an attractive design of housing, integrated with all optical components. The software program will be enhanced in accuracy and speed. The hardware is tested extensively to check if optical/mechanical refinement is required. The practical needs in the industry will be investigated through market survey and tests on various human figures. Then an attempt will be made to commercialize it based on market needs. Phase 2: Optical advancement of moire topography Based on our experience, further research can be made on optical advancement to increase the moire fringe visibility. The work include a feasibility test of using flash light, optimization of the grid pitch, increase of CCD resolution, using macro design lens, installation of film cartridge at focal plane, enlarging the scanning format, improvement of hardware mechanism, and making even light brightness. Phase 3: Development and commercialization of a multi-head body scanner In this stage, an advanced version of multi-head body scanner will be developed. Light is projected through high density grid on to the body by flash tubes for quick shots. The images can be simultaneously transferred into a computer for fringe analysis. The 3D data are then used to map a body surface and the required body dimensions will be extracted by computer program. Phase 4: Visualization of 3D human body A software program will be developed to perform the following tasks: generate virtual human body using the 3D data cloud; project a virtual garment on the virtual mannequin; project texture on to the virtual garment; display the 3D images on the monitor; and produce garment patterns based on built-in procedure or using 3D pattern mapping method.
