GOBO projection based high speed three dimensional shape measurement
Pattern projection based three dimensional (3 D) measurement systems are well established in various application fields. However, for some time, there has been an increasing demand in terms of a higher measurement speed in order to analyze fast processes. We introduce a GOBO slide based projector (GOes Before Optics) providing high speed, high radiant flux, and eye safe incoherent light at low cost. We present its setup as well as the generation and change of the projected patterns. We explain the 3 D measurement principle and show first measurements of an inflating airbag and a rope skipper conducted at a 3 D frame rate of more than 1.3 kHz.
