The work studies 3D measurement with digital projector based on structured illumination, the development of which enabled the discovery of DLP technology. The Master thesis presents performance and usability of DLP technology in optical 3D measurement. In addition, a market research of autonomous DLP projectors has been carried out, which can be part of 3D optical measuring system. Then, a single shot and multi-shots structured-light surface 3D imaging techniques used in 3D measurements are explained. With the experiment was determined the influence of the structured light pattern period on measurement accuracy in order to optimize the existing measurement system. Based on experiment results, the simulation of measuring accuracy was performed for existing measurement system by changing DLP projector. In this way, the digital projectors which were found during market research, are classified.
