Abstract: Provided are a device positioning method, a terminal, a server and a storage medium. The device positioning method includes the following steps: after a target device loses contact, a master device sends help-seeking information to a server; after receiving the help-seeking information, the server sends an assistance positioning instruction to an assistance terminal, so that the assistance terminal is instructed to scan for a surrounding device, and determines whether scanned identification information is matched with identification information in the assistance positioning instruction; if the scanned identification information is matched with the identification information in the assistance positioning instruction, the assistance terminal sends positioning information of the assistance terminal at a scan success time to the master device.
