3D Shape measurement system based on structure light and polarization analysis

The problem of 3D shape acquisition has received increasing attention in recent years. Recently the structure light measurements system based on digital light projection supported by processing allow to rapid acquisition of data about 3D real objects. Obtaining 3D shape of objects in optically scattering media presents a challenging set of problems. Many applications for 3D imaging through fog, dust, mist, rain and turbid water require improving the quality of data obtained in scattered media. Presented 3D shape measurement system is supported by polarization image analysis. Enhancement of image quality is realized using the detector unit with special liquid crystal filter.
