  • Publication number: 20210372798
    Abstract: The present disclosure provides a visual navigation method and system for mobile devices based on QR code signposts. The visual navigation method for movement includes: autonomously planning an optimal route according to a destination specified by a user, performing positioning in an image captured by a trolley camera and recognizing signpost information, and adjusting a pose according to the signpost information and going to a signpost in the path. In this process, positioning is performed in real time and route planning is updated, and a user may change the destination at any time in a trolley navigation process according to a robust anomaly recovery decision. The method disclosed by the present disclosure not only proposes an indoor navigation solution that does not rely on a GPS signal and strong computation resources, but also can effectively meet an indoor scheduling scenario in which a path needs to be planned intelligently.

  • Publication number: 20210375512
    Abstract: An anisotropic bonded magnet and a preparation method thereof are provided. Through a method of stacking magnets which are different in content of SmFeN and/or have different densities, the magnets in the middle have high properties and the magnets at two ends and/or the periphery have low properties, thereby compensating for a property deviation caused by a difference in densities during a pressing process, and improving the property uniformity of the magnets in an axial direction. The method avoids the phenomenon of non-uniform magnetic field orientation and density in a height direction during orientation and densification as well as the phenomenon of low in the middle and high at two ends.

    Abstract: An anisotropic bonded magnet and a preparation method thereof are provided. By stacking magnets having different magnetic properties and/or densities, the magnets in the middle have high properties and the magnets at two ends and/or the periphery have low properties, thereby compensating for a property deviation caused by a difference in pressing densities during a pressing process, and improving the property uniformity of the magnets in an axial direction. The method solves the problem of “low in the middle and high at two ends” caused by the phenomenon of non-uniform magnetic field orientation and density along a height direction during orientation and densification.
