The utility model discloses a leather cutting machine partition adsorption structure which comprises a rack, a cutting panel is arranged at the top of the rack, a plurality of adsorption holes are formed in the cutting panel, an air pipe is arranged below the cutting panel, the air pipe is externally connected with a vacuum pump, and the air pipe corresponding to the adsorption holes is connected with the bottom face of the cutting panel through a branch air pipe. An air cylinder is arranged corresponding to each branch air pipe, the output end of each air cylinder is connected with a partition plate, and the partition plates can stretch into the ends of the branch air pipes to open or close the branch air pipes. The vacuum adsorption mode is adopted for fixing the dermis, damage to the dermis is small, obvious traces or tensile deformation cannot be left on the surface of the dermis, the original state and quality of the dermis can be well kept, the vacuum adsorption type dermis fixing device can adapt to dermis of various shapes and sizes, and regular rectangles or irregular shapes can be effectively fixed.

The application provides a point cloud completion method and device and a storage medium, which comprises the following steps: collecting original images and stripe images of an object through a binocular structured light system; reconstructing a point cloud with high precision but with reflection and dark area missing by using the stripe images; meanwhile, calculating a disparity map by using a FoundationStereo deep learning model for stereo matching based on the original images to obtain a point cloud which is complete but has lower precision than the stripe image reconstruction; in order to meet the point cloud coordinates in the two three-dimensional reconstruction methods, the point cloud coordinates of the two reconstruction methods are corrected based on a standard ball multi-position reconstruction data calculation error model; firstly, the two point clouds are spatially registered and aligned; then, the missing area of the high-precision point cloud is analyzed, the corresponding area in the low-precision point cloud is located through image mapping, and the point cloud of the corresponding area is extracted as a patch. The application effectively solves the data missing problem of the structured light measurement in the reflection and dark area, and realizes the balance between the point cloud precision and completeness.

The utility model provides a geological exploration sample storage device, including box body, inner pad, the bottom fixedly connected with inner pad in the inside of box body, the inside fixedly connected with the baffle of box body. The utility model has the advantages of: single sample is placed in single lattice, and the soft gel is compacted, and the sealing membrane can be closely combined with the geological sample, effectively prevent the sample from being damaged by the external physical impact in the transportation or processing process. The soft gel provides additional buffering effect, further reduces the risk of sample damage due to vibration or bumping, the sealing membrane and the soft gel can isolate the sample from the external environment, prevent moisture, dust, chemical substances and other pollutants from entering the sample, thereby maintaining the original state of the sample and ensuring the accuracy of subsequent analysis. The use of sealing membrane and soft gel simplifies the sample processing process. Compared with the traditional wrapping method, they are easier to operate, and no additional fixing or supporting equipment is needed, thereby improving the work efficiency.
