Abstract: A method of searching for a business by constructing an index tree using a geographic location of a user is provided. In some examples, the method includes obtaining the geographic location of the user, and retrieving circumscribed rectangles covering the geographic location with a pre-constructed index tree, where the circumscribed rectangles are a smallest circumscribed rectangles covering delivery areas of businesses (101). Target delivery areas covering the geographic location are determined from the delivery areas corresponding to the circumscribed rectangles(102). Businesses corresponding to the target delivery areas are determined as deliverable businesses corresponding to the geographic location(103).

Abstract: The embodiments of the present disclosure relate to an unmanned delivery device, a delivery robot dispatching method, and an electronic device. The unmanned delivery device includes a container body, M delivery robots and a transfer module. The container body is provided with M cabinet groups and each of the cabinet groups is used to store goods to be delivered by a corresponding delivery robot. The container body is configured to identify a target delivery robot, determine order information of target goods stored in a target cabinet group corresponding to the target delivery robot, and instruct the target delivery robot to deliver the target goods according to the order information. The transfer module is used to move the target goods stored in the target cabinet group corresponding to the target delivery robot to the target delivery robot.

Abstract: Disclosed are indoor positioning methods, apparatuses, electronic device and computer readable storage medium. The indoor positioning method includes: obtaining state data of a mobile terminal; based on a pre-trained position classification model, determining a position classification of the mobile terminal according to the state data of the mobile terminal; when the position classification of the mobile terminal is an anchor point position, taking the mobile terminal as a beacon terminal and sending an anchor point position broadcast instruction to the beacon terminal to enable the beacon terminal to broadcast the anchor point position. In the technical solution, a mobile terminal meeting anchor point requirements is taken as a beacon terminal to provide convenient positioning services, so as to avoid deployment and maintenance of a large number of beacons, hardware of routers, and related mapping relationship, thus greatly reducing investment costs and facilitating promotion of use.
