1. A positioning method, comprising:
establishing, in response to feedback information returned by the target node according to a positioning request sent by a source node, connection with a target node;
acquiring initial position information, wherein the initial position information comprises the initial position of the source node and the distance between the source node and the target node;
acquiring real-time position information for multiple times, wherein each of the real-time position information comprises: the direction and the distance of the movement of the source node relative to the last position of the source node, the direction and the distance of the movement of the target node returned by the target node relative to the last position of the target node, and the distance between the target node and the source node, wherein the last position information of the source node and the target node is acquired through the following steps: (a) step of acquiring the initial position information, or (b) acquiring real-time position information at the last time; and
positioning the target node according to the acquired initial position information and at least two of the real-time position information acquired for multiple times; wherein
in each acquired real-time position information, at least one of the following position information is different from the corresponding position information acquired last time: the direction of the movement of the source node relative to the last position of the source node, the distance of the movement of the source node relative to the last position of the source node, the direction of the movement of the target node relative to the last position of the target node, and the distance of the movement of the target node relative to the last position of the target node.
