The application provides a metal pipe inner wall rust inhibitor AI spraying track planning method and system based on visual guidance, relates to the field of industrial automatic spraying technology, and the method comprises the following steps: acquiring original sequence images of a metal pipe inner wall collected by an endoscopic visual probe, performing optical distortion correction and multi-view point cloud space registration on the original sequence images to obtain an inner wall three-dimensional topological grid; extracting node coordinates and surface normal vectors of the inner wall three-dimensional topological grid, and calculating local curvature gradient distribution of the node coordinates and the surface normal vectors; performing threshold segmentation and feature boundary extraction on the local curvature gradient distribution to obtain a geometric feature partition graph of the spatial range of the thread groove bottom, the windward surface of the reinforcing rib and the weld reinforcement area. The application improves the uniformity of the coating and the protection reliability.

The present application relates to the technical field of tobacco production, and provides a wet dust collector, which comprises a dust removal cylinder, a flue gas inlet installed at the lower part of the dust removal cylinder, and a spraying component installed in the flue gas inlet and used for spraying washing liquid into flue gas, a fan is installed at the top of the dust removal cylinder, and a flue gas outlet is installed on the fan; a micro-permeation liquid membrane assembly is arranged on the inner top of the dust removal cylinder, and the micro-permeation liquid membrane assembly is connected with an inner cavity water supply assembly installed on the inner top of the inner wall of the dust removal cylinder; the micro-permeation liquid membrane assembly comprises a cylindrical sleeve arranged on the inner top of the dust removal cylinder and a sealing ring used for connecting the cylindrical sleeve with the inner cavity water supply assembly. In use, through the cooperation of variable-pitch spiral agglomeration and micro-permeation liquid membrane capture, the present application actively promotes the agglomeration and weight gain of superfine smoke dust, the micro-permeation liquid membrane provides a stable and reliable final capture surface, and the combination of the two ensures that the outlet smoke dust concentration is stable and meets the increasingly strict ultra-low emission requirements of the tobacco industry.
