Problems solved by technology
[0004] However, in related technologies, no matter which positioning map is used, it is necessary to solve the problem of map update and management
Because the on-site environment will gradually change over time, the scene information collected when building the map for the first time may not match the information perceived by the current device at all, resulting in the inability to locate
For example, when building a map, a certain store scene was photographed. If the store has been renovated and upgraded after a while, it will be difficult to successfully locate it when the device shoots at this place.
[0005] At present, no effective solution has been proposed for the problem of how to update the management positioning map to adapt to the changed scene in related technologies

The invention relates to a method, system and device for updating and managing a positioning map and a medium, and the method comprises the steps: obtaining the positioning map, and carrying out the initialization of the positioning map; then the positioning map is detected through a positioning capacity detection algorithm, the current detection result of the positioning map is obtained, and parts needing to be defined in the detection process comprise the detection opportunity, the detection source and the detection method; and performing corresponding updating management on the positioning map according to the detection result. According to the method and the device, the problem of how to update and manage the positioning map to adapt to the changed scene is solved, and the positioning accuracy and the user experience are improved.
Description
technical field [0001] The present application relates to the technical field of three-dimensional reconstruction, and in particular, to a method, system, device and medium for updating and managing a positioning map. Background technique [0002] With the rapid development of computer technology, augmented reality (AR) technology has gradually penetrated into more industries and application scenarios. Among the technologies that AR applications rely on, the construction of locatable maps of real scenes is the most basic and critical link, because AR applications generally require automatic positioning of AR devices in the scene, and it is necessary to achieve automatic positioning. The premise is a locatable map and a positioning algorithm. [0003] Generally speaking, the automatic positioning process of AR devices can be abstracted and simplified as: obtaining scene content and device status → querying map space points → constructing space point and scene content constra...
