Active stereo vision
Doležal, Milan ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
This thesis deals with active stereo method for measurement of objects with transparent layer. In theoretical part of this thesis is described method of active triangulation and method of active stereo. After that, there is research of articles focused on transparent layer in optical measurement. Next chapters deal proposition of measuring system, it's parameters, calibration, procedure and evaluation of measurement. MATLAB was selected as programming platform.
Konstrukční úpravy dataprojektoru pro optická 3D měření
Pochmon, Michal ; Pravdová, L. ; Rössler, T.
Optical profilometric and topographic non-coherence measurements have a great use today, for example in deformation measurement, product quality control, total arthroplasty wear measurement and many others. These measurements are based on using optical structure, which is projected on the measured object and is deformed by its surface. Good projector of such optical structure is data-projector. Its imperfection is too large zoom of serial objective, so measurement of small objects is influenced by quite big measurement error. This is caused by projecting only small part of optical structure is projected on measured object and that negative influences resolution of measurement method. For the measurement of small objects is necessary replace the serial objective by objective, whom parameters allow the measurement of this object influenced by the measurement error as small as possible.
