The utility model discloses a camera group of crystal seed observation and shooting, aims at solving the problem of complex structure, inconvenient operation, unstable imaging and poor effect of crystal seed observation equipment in the prior art. The camera group includes: the object carrying base platform, sets up the lifting adjustment support on the platform, fixes the camera on the support, is connected in the camera bottom's microscope head and is provided with the light source part in the microscope head bottom. The lifting adjustment support adopts the structure of gear and rack meshing to realize accurate focusing, the object carrying base platform is equipped with the positioning sheet for sample accurate positioning, and the light source part is integrated light source. The utility model integrates each functional part into an organic whole, has the advantages of simple and compact structure, stable and clear imaging, accurate focusing, accurate positioning and convenient operation, greatly improves the efficiency and quality of crystal seed observation and shooting.

This invention relates to the field of computer graphics technology, and more particularly to a method, system, device, and medium for verifying 3D models. The 3D model verification method includes the following steps: Step S1: Receive the user's detection command in real time and obtain the 3D model to be verified; Step S2: Analyze the 3D model to be verified and obtain geometric feature information and material feature information; Step S3: Match the geometric feature information and material feature information with the geometric feature information and material feature information of existing 3D models in the system's database one by one to determine whether they are consistent. If they are consistent, the first operation is performed; if they are inconsistent, the second operation is performed. This invention is aimed at 3D models with materials in the design industry, and achieves rapid storage and management of 3D models through a precise and effective verification method.
