Optical 3D measuring systems allow accurate, fast and contactless measurement of bodies. They are useful in many fields of technology, medicine and science. Since the development of digital light projectors, there are new possibilities of improving optical 3D measuring systems, especially in terms of increasing the speed and reliability of measuring.
The thesis is focusing on the development of an optical 3D measuring system assembled from low-cost and commercially available components for open public while still achieving competitive accuracy and measuring range. To fulfil these goals the thesis is examining the selection and design of appropriate components, their geometrical position and development of supportive housing. Furthermore the thesis is considering and discussing the development of software for controlling and synchronization of components in order to capture measuring data. In addition the software supports processing of captured data and reconstruction – resulting in converting raw data into point cloud. Moreover the software supports connectivity to external devices and data export. Chosen measuring range is between 0.5 m and 1 m from measuring system. The achieved accuracy of the optical 3D measuring system is determined by calibrating it using reference measuring body. Standard deviation of measured points is 0.2 mm. Along this the thesis investigates the influence of important geometric and software settings on accuracy and measuring range.
