Paper Abstract

A three-dimensional shape measurement system based on fiber-optic image bundles was proposed to measure three-dimensional shape of object in confined space. Fiber-optic image bundles have the advantage of flexibility. Firstly, based on the principle of phase-shifting and advantages of fiber-optic image bundles, the mathematical model of the measurement system was established, hardware and software platform of the system was set up. Then, the problems of calibration and poor quality images brought by fiber-optic image bundles were analyzed, after which a viable solution was proposed. Finally, experiments for objects in confined space were performed by using the three-dimensional shape measurement system. As the transmission media of the system, fiber-optic image bundles could achieve picture’s flexible acquisition and projection. The three-dimensional shape of the object was reconstructed after data processing of images. Experimental results indicated that the system was miniature and flexible enough to measure the three-dimensional shape of objects in confined space. It expanded the application range of structured-light three-dimensional shape measurement technique.
