Field: Measurement (Instruments)
Classification: CPC G  B | IPC B  G

Claim 13:
14. A positioning method, comprising:
receiving a wireless positioning coordinate of a moving object;
determining a visual sub-map to be matched in a visual map database based on the wireless positioning coordinate; and
obtaining a visual positioning coordinate corresponding to a current image of the moving object captured at time of wireless positioning as a positioning result, based on the determined visual sub-map to be matched;
wherein the positioning method further comprises:
determining a projection point of the wireless positioning coordinate on a preset path as a positioning result, based on a planar environment map of a positioning coverage area;
wherein determining a projection point comprises: determining whether a navigation path has been generated within the planar environment map; if so, projecting the wireless positioning coordinate onto the navigation path, and if not, projecting the wireless positioning coordinate onto an accessible path in the planar environment map;
wherein an operation of projecting the wireless positioning coordinate onto the accessible path comprises: determining an accessible path in the planar environment map with the smallest included angle relative to a direction of the moving object and at the closest distance to the wireless positioning coordinate; and taking a projection point of projecting the wireless positioning coordinate onto the accessible path which has been determined as a positioning result.
