Abstract: Disclosed is a multi-angle image semantic segmentation method for cadmium zinc telluride chips, belonging to the field of image quality augmentation. Firstly, construction of an n+1 dataset is performed by using acquire CZT images, and then pixel-level and latent-level knowledge representation is performed through a Pixel Aggregation Network PAN and a Latent Aggregation Network LAN in a Progressive Complementary Knowledge Aggregation network PCKA, which ultimately improves the quality and speed of CZT image segmentation. The method is suitable for applications that require multi-angle image acquisition and semantic segmentation, such as semiconductor material segmentation.

Abstract: A method for preparing a multilayer metal composite pipe includes steps of: internally and externally grinding blank pipes; cleaning oil stains; assembling a multilayer metal pipe; drawing to reduce a diameter; performing high-speed friction welding at the pipe ends; performing heat treatment; performing four-roller cross-rolling; straightening; performing two-roller cold-rolling; performing cold-drawing to reduce the diameter; performing cold-expansion to reduce the diameter; performing precise cold-rolling; degreasing; brightening; performing surface grinding; cleaning dust; detecting multilayer metal interface bonding; detecting flaws; testing metal structure performance; and sizing and packaging. By cycling the cold-drawing, the cold-expansion, and the precision cold-rolling, key indicators such as product dimensional accuracy, surface quality, material properties, and crystal grain size can be collaboratively controlled, so as to achieve higher accuracy, better performance, and more outstanding extreme specifications. The present invention solves the problem of inconsistent extension due to differences in metal properties.

Abstract: A dynamic straightening method for a left/right tilt. The method includes: drawing an unevenness curve according to a distance from a shapemeter to a surface of a plate, where there are a plurality of unevenness curves; using a barycentric formula to obtain a first barycentric coordinate of each unevenness curve; calculating a tilt value of a straightening roll corresponding to each unevenness curve according to the first barycentric coordinate of each unevenness curve; determining an unevenness curve of a current straightening roll; adjusting the straightening roll according to the tilt value of the straightening roll corresponding to the unevenness curve, to straighten the plate; and going back to the step of determining an unevenness curve of a current straightening roll until the plate is totally straightened. Such method improves plate straightening accuracy by dynamically adjusting parameters of the straightening roll.
