The embodiment of the invention provides a map generation method, and an indoor navigation method, device and equipment. According to the method, a three-dimensional building model of a target building is obtained, and a floor conversion point of each floor is marked in the three-dimensional building model; a conversion type corresponding to each floor conversion point is determined, a conversioncost weight corresponding to each conversion type and a path type corresponding to different road sections of each floor are set, and a path cost weight corresponding to each path type is set; a three-dimensional map is generated based on the three-dimensional building model. to the method is advantaged in that through the three-dimensional map provided, a foundation is provided for cross-floor path finding in a building, and one or more navigation paths are obtained by combining at least one conversion path between at least one starting floor conversion point and at least one target floor conversion point, furthermore, based on the conversion cost weight and the path cost weight, the foundation is laid for calculating the path weight of each navigation path to obtain the optimal navigation path.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method for generating a map, an indoor navigation method, device, and equipment. Background technique [0002] At present, large shopping malls, supermarkets and other shopping places, as well as large residential buildings or office buildings, provide customers with in-building navigation services in order to facilitate users to quickly find a target location. [0003] However, the existing navigation service in the building is to find the way of the building in layers according to the number of floors of the building, and use the two-dimensional map navigation to realize the navigation of each floor in the building. However, users usually have a lot of cross-floor movement needs in multi-storey buildings, such as shopping malls. However, the current navigation methods in buildings cannot provide users with cross-floor navigation services and ...
