Array-projected aperiodic sinusoidal fringes for high-speed 3-D shape measurement

In recent years, the demands on three-dimensional (3-D) measurement systems have been getting higher, es- pecially concerning their speed. The use of a 3-D array projector enables measurement frame rates of up to the 100-kHz range. Our contribution introduces a new purpose-built setup that projects aperiodic sinusoidal fringes. We explain the 3-D measurement principle and the basic design of a 3-D array projector and describe the method how the desired aperiodic sinusoidal fringes are generated. We verify the consistency between specified and projected patterns and point out the results of the setups’s characterization, e.g., of its high-speed capability. Furthermore, first 3-D shape measurements at a projection frame rate of 3 kHz resulting in a 3-D frame rate of <330 Hz are presented and evaluated.
