Traditional coded structured light with spatial neighborhood is a well-known technique which is used to acquire 3D information. In this paper, we use stereo structure by adding a camera so that the calibration of projector could be omitted. By projecting a new color stripe pattern in which the thick stripes are encoded of De Bruijn sequences with six different channel values and order three, while...
This paper introduces an image fusion technique on a gated image. Gated imaging is a powerful technique to capture images in turbid condition. By controlling the time delay of the shutter to capture the returning light, we can obtain the image at different depth. Modular transfer function (MTF) is used to evaluate the quality of the gated images. Images with useful information (clear and sharp objects)...
A novel phase-unwrapping algorithm is proposed by using interlaced fringe in optical 3-D measurement. In the measurement, a four-step phase-shift method including four sinusoidal fringes with 90 phase shift is used. On top of these four fringes, an interlaced fringe is encoded. In the measurement, all these designed fringes are projected onto the tested object, and fringe images are acquired...
