| Abstract;Raster and vector are two common forms of graphics display systems. In this paper we introduce a new approach to display vector graphics by using a laser projector. The laser beam does not diffuse nor lose intensity over distance. These characteristics make laser projection suitable for large scale graphics. Laser projector is different from vector-based display in a way that it has its own properties such as the speed of laser beam and inertia of the reflective mirror. In this paper we present a method for creating vector data from an image and projecting using laser projector. The process starts by first extracting the binary image of the raster image and find contours then obtaining polygonal approximation of raster shape. Through this process, we converted a raster image according to the levels of its grey scale to a vector image that can be displayed using a laser projector. A Morphing technique is also proposed to create laser animation from a single candle vector data. A recursive vector subdivision algorithm is used to achieve smoother result. (author abst.) |
