5results about How to "Excellent flexibility" patented technology

This invention relates to the field of pose estimation technology, specifically to a multi-view, multi-person 3D pose estimation method, apparatus, and device. The method includes: acquiring image information and depth information of the target using multi-view acquisition technology; segmenting the person in a single view based on the image information and extracting 2D semantic features; reconstructing the point cloud based on the depth information to obtain a 3D point cloud in a preset world coordinate system; segmenting the point cloud for different human figures based on the 3D point cloud and calculating the point cloud boundaries as human body boundaries; mapping the 2D semantic features to the 3D point cloud to obtain 3D features; and classifying different human figures and constructing 3D poses based on the 3D features and human body boundaries. This technical solution can segment the point cloud for different human figures based on the 3D point cloud, accurately define the joint positions of different figures, and achieve differentiation and matching of different figures. Furthermore, based on discrete point cloud data, it has better flexibility and fault tolerance.

The invention discloses a temperature control ventilation system shared by a finished grain bin and an original grain bin and an application method, and relates to the technical field of grain bin ventilation. The temperature control ventilation system comprises an integrated refrigerating unit, a bottom air supply structure, a middle socketed pipe splicing piece, a double-area air direction distribution box, a top grain surface air supply structure, a double-area wall cold air valve assembly and a double-area air pipe; through organic cooperation of the middle air supply module and the top air supply module, the three-dimensional ventilation device capable of freely switching the ground cage mode and the grain surface mode is constructed. Switching of the air supply mode is controlled through opening and closing of the air valve, the airflow speed and pressure distribution are optimized, and the problems of air volume loss and backflow dead angles are effectively avoided. The problem of air supply limitation of short-term storage of unprocessed grains in the finished grain warehouse is innovatively solved. Compared with a traditional finished product grain bin ventilation device, the mode flexible switching and operation stability are better, the technical bottlenecks that a traditional grain storage air supply mode is single and the regulation and control precision is insufficient are broken through, and good engineering adaptability and popularization and application prospects are achieved.

The invention relates to the technical field of high polymer materials and coatings, in particular to a flame-retardant solid powder coating with a hydrophilic metal matrix and a preparation method of the flame-retardant solid powder coating.
