Abstract: The present invention discloses a 3D scanning control apparatus based on FPGA, for controlling a 3D scanner to scan. The apparatus comprises: a first projection control module, for controlling a structured light generation unit to project to an object; a first image acquisition control module, for controlling a shooting unit to capture a projection image of the object when the first projection control module is projecting; a second projection control module, for controlling another structured light generation unit to project to the object for one more time; a second image acquisition control module, for controlling a corresponding shooting unit to capture the projection image of the object for one more time when the second projection control module is projecting; and a data processing module, for processing the captured projection images with at least one of the Bayer color rendition, color space conversion and phase unwrapping, by using algorithm in the FPGA.

Abstract: The present invention discloses a fastening structure based on ratchet mesh. The fastening structure includes a ratchet sleeve shaft comprising at least one first ratchet portion set on an outer surface thereof, an adjustable sleeve shaft sleeved in the adjustable sleeve shaft and being rotatable around a central axis thereof, and an elastic ratchet plate separately sleeved on the ratchet sleeve shaft. The elastic ratchet plate includes a second ratchet portion corresponding to the first ratchet portion and at least one end fixed to the adjustable sleeve shaft.
