The application provides a terahertz waveguide cascade connection system, belonging to the technical field of waveguide flange connection, comprising a front-stage connecting device, a rear-stage connecting device and an intermediate gasket; the front-stage connecting device has an output waveguide hole; the rear-stage connecting device has an input waveguide hole with a hole diameter equal to that of the output waveguide hole; the input waveguide hole is misaligned with the output waveguide hole; the intermediate gasket is clamped and abuts between the output side of the front-stage connecting device and the input side of the rear-stage connecting device; the intermediate gasket has a waveguide passage, one end of which has a hole diameter equal to that of the output waveguide hole, and the other end has a hole diameter larger than that of the output waveguide hole, and the difference between the large-end hole radius and the small-end hole radius of the waveguide passage is larger than the misalignment error; the small-end hole of the waveguide passage is coaxially arranged with the input waveguide hole, and the large-end hole of the waveguide passage is arranged on the output waveguide hole. The terahertz waveguide cascade connection system provided by the application can effectively reduce the transmission loss caused by cascade error and improve the quality of signal transmission.

The application discloses a waveguide antenna assembly precision visual calibration method and system, and belongs to the technical field of waveguide antenna assembly. In the state that the waveguide antenna and the docking component are not in contact, a multi-view high-resolution industrial camera and a structured light projection are used to synchronously collect a waveguide flange surface image, and a three-dimensional appearance is reconstructed through phase demodulation; based on the image and the point cloud, a port center axis, a waveguide flange surface normal vector and a positioning reference are extracted, and flatness and edge continuity are calculated; geometric features are matched with a standard assembly model, a six-degree-of-freedom pose deviation is solved through singular value decomposition, visual guidance instructions are generated according to a preset tolerance threshold, a closed-loop dynamic calibration is driven by an adjustment platform, and the process is paused when there is an edge defect. The application changes the assembly calibration from a posteriori mechanical contact to a prospective geometric alignment based on visual detection, realizes intelligent assembly of non-contact real-time guidance, and significantly improves the assembly precision and consistency of the waveguide system.
