Light-folded projection three-dimensional display.
A light-folded projection three-dimensional (3D) display system with a single projection lens and a rectangular light tunnel which is composed of four folding mirrors on its inside walls is proposed. It is theoretically shown through the Wigner distribution function analysis that the proposed system can generate the same light field effectively as that of the conventional projection-type multiv...

Three-dimensional surface reconstruction using a handheld scanner is a process with great potential for use on different fields of research, commerce and industrial production. In this article we will describe the evolution of a project comprising the study and development of a system that implements the aforementioned process based on two-dimensional images. We will present our current work on...
متن کاملOverview of Coded Light Projection Techniques for Automatic 3D Profiling
Obtaining automatic 3D profile of objects is one of the most important issues in computer vision. With this information, a large number of applications become feasible: from visual inspection of industrial parts to 3D reconstruction of the environment for mobile robots. In order to achieve 3D data, range finders can be used. Coded structured light approach is one of the most widely used techniq...
متن کامل3-D Shape Reconstruction from Light Fields Using Voxel Projection
We present a method for the 3-D reconstruction of objects from light elds. The estimated shape and texture information can be used for the compression of light elds or a better intermediate view interpolation. The representation of the objects is fully voxel-based and no explicit surface description is required. The approach is based on testing multiple voxel color hypotheses back-projected int...
متن کامل3D shape modeling by color phase stepping light projection
Color encoded phase-stepping light projection method is a new and promising technique for 3D shape modeling However, the 3D model acquired is often smeared by large error. The main cause of the error is color coupling amongst the three primary colors RGB. In this paper, we first analyzed the color-coupling problem. It is found that there is a strong coupling between G and R element. The couplin...
