An eco-friendly board based on single mortise and tenon joint
This utility model discloses an eco-board based on single mortise and tenon joint. The eco-board includes sub-wood strips and mother-wood strips, and the transverse direction of the eco-board is spliced using mortise and tenon joints, while the longitudinal direction is spliced using toothed joints. Its advantages are as follows: Compared with double mortise and tenon joints, the eco-board of this utility model, using a single mortise and tenon joint, has higher process efficiency and better economy. The processing time for single mortise and tenon joints can be reduced by 30%-50%, making it particularly suitable for mass production and requiring lower equipment precision. Secondly, it reduces the grooving process, lowering labor and tooling costs. Furthermore, the single mortise and tenon joint reduces material removal, making it suitable for scenarios requiring weight reduction (such as hanging cabinets and movable furniture). Moreover, the single mortise and tenon joint is particularly suitable for thin boards, requiring no larger board thickness for support, and can be used stably in eco-boards with a thickness of less than 18mm, thus broadening its application range.

Image intelligent stitching method and stitching system based on deep learning
ActiveCN118608379Bimprove clarityincrease contrastImage enhancementImage analysisImaging processingFeature extraction
The present invention provides an image intelligent splicing method based on deep learning and a splicing system thereof, which belongs to the field of image processing technology. By constructing a deep convolutional neural network model, feature extraction and feature encoding are performed on each image to be spliced, and feature representation and context encoding of the image block are obtained. Then, the fusion weights of adjacent images to be spliced are calculated in combination with the feature representations and context encodings of adjacent images to be spliced. Based on the fusion weights, adjacent images to be spliced are fused using a gating mechanism to obtain a preliminary spliced image. Finally, a panoramic optimization generation network is used to iteratively optimize and enhance the preliminary spliced image to obtain a final spliced image. The present invention can more accurately match and fuse the overlapping areas of adjacent images, thereby significantly improving the precision of image splicing, reducing splicing gaps and misalignment phenomena, and improving the clarity and contrast of the image, making the spliced image more natural and realistic.
