The invention discloses a positioning method and device and a mobile terminal. The method comprises the following steps: determining an actual distance between a first position and a second position of a target according to a preset model, and determining a heading angle corresponding to the actual distance according to a direction sensor, wherein the first position is a position corresponding toa current sampling time, and the second position is a position of a previous sampling time adjacent to the current sampling time; and determining a first position of the target according to a predetermined reference position, the actual distance and the heading angle, wherein the first position is used as the predetermined reference position for calculating a third position, and the third positionis a position of a next sampling time adjacent to the current sampling time. The positioning method can determine various positions in a moving process in the process of continuously moving the target, and the positioning method does not need the support of a network and can realize accurate positioning.
Description
technical field [0001] The present invention relates to the field of positioning, in particular to a positioning method, device and mobile terminal. Background technique [0002] With the rapid development of the Internet, location-based services have become an indispensable part of people's lives, and positioning technology, as one of the key technologies of location-based services, has also attracted more and more attention. Positioning technology as a whole can be divided into indoor positioning and outdoor positioning. Outdoor positioning generally adopts the Global Positioning System (GPS, Global Positioning System). Provide precise positioning services. [0003] However, in large indoor occasions such as shopping malls, underground garages and exhibitions, people's demand for accurate indoor positioning is becoming increasingly urgent. For general users, in an unfamiliar and complex indoor environment, accurate positioning can help users know their own location in re...
