The invention provides a solution according to which the diameters of a large plurality of cylindrical measuring pins (1A-1E) can be measured fast and accurately, while using an affordable, non-complex and universally applicable measuring apparatus. In concise summary, the key features of the invention are formed by using a two-dimensional tracing apparatus (10) having a simultaneous holding structure (12) for simultaneously holding the measuring pins in fixed positions relative to the apparatus frame (11), while the measuring pins are alongside one another with their central axes parallel to one another, and by performing first and second joint tracing operations by tracing against and along diametrically opposite first and second parts of first and second circular sections of the cylindrical outer surfaces of the measuring pins, to thereby determine measured values of the diameters.

A depth measurement assembly (DMA) includes a pulsed illuminator assembly, a depth camera assembly, and a controller. The pulsed illuminator assembly has a structured light projector that projects pulses of structured light at a pulse rate into a local area. The depth camera assembly captures images data of an object in the local area illuminated with the pulses of structured light. An exposure interval of the depth camera assembly is pulsed and synchronized to the pulses projected by the pulsed illuminator assembly. The controller controls the pulsed illuminator assembly and the depth camera assembly so that they are synchronized. The controller also determine depth and/or tracking information of the object based on the captured image data. In some embodiments, the pulsed illuminator assembly have a plurality of structured light projectors that projects pulses of structured light at different times.
