The invention discloses a pet bin and an outdoor pet cart, and relates to the technical field of pet carts, the pet bin comprises a bin body, the bin body is provided with a bin bottom and a bin wall arranged on the bin bottom in a surrounding mode, so that the bin body is integrally of an open structure, and the bin wall in the surrounding state has a high surrounding state blocking the view and a low surrounding state opening the view relative to the height of the bin bottom; the inner side, in the low enclosure state, of the bin wall is designed in a protruding mode so as to form a lying table facing a user. According to the invention, through the design of gradual transition descending from the high enclosure state to the low enclosure state, unconscious direction guidance for the pet is formed, so that the sight of the pet is more easily transferred to the low enclosure state direction due to the shielding of the high enclosure state, and when a user stands around the low enclosure state, the user can perform effective visual contact and interaction with the pet.

The present invention relates to a method for anchoring and aligning of virtual content using augmented reality (AR) technology for the construction of simulators for maritime and naval operations on board of ship bridges. The simulator enables the execution of training scenarios with virtual objects and content while maintaining visual contact with the real environment, whether the ship is sailing in open-sea or moored alongside a berth. In particular, the present invention describes a two-layer anchoring and alignment method, which serves as a technique for accurately synchronizing virtual objects and content with the real environment during vessel movement relative to true north, while also compensating for the user's movements, allowing realistic display through the user's augmented reality glasses.
