• abstract: Aiming at the need of verticality and parallelity in the process of equipping elevator for high building. The method is in operation in which frosted glass are rayed by laser collimating beam brought with concentric circles interference fringes, the image can be captured by using CMOS sensor, and can be processed automatically when carried into computer by USB I/O. Based on Hough transform algorithm, the center of concentric circles diffraction fringes can be automatically acquired and tracked at quasi-real-time condition. The range is 128 × 96 mm2 which the circle diffraction fringe can be received, and the precision of center coordinates is about 1 or 2 pixels. It is proved that the method can greatly meet the need of building measurement, and that can be applied to all sorts of highly precise collimating measures.
