A positioning method comprises the following. Detecting an image marker and receiving an additional information, wherein a first pose information of a first positioning device relative to a target anchor point is included in the additional information, the first positioning device and the target anchor are outside a first positioning space, and a second positioning device is in the first positioning space. Obtaining a second pose information of the second positioning device relative to the first positioning device according to the image marker. Obtaining a positioning-pose information of the second positioning device in the first positioning space through a positioning means which is different from an image marker detection means. Obtaining the target pose information of the target anchor relative to the first positioning space according to the first pose information, the second pose information and the positioning-pose information.

Positioning method, operating method and positioning device

A network quality measurement method and system are provided. In the method, a movement path and a movement speed of a vehicle device are determined according to a size of a space and an endurance time of the vehicle device, and the vehicle device is controlled to move on the movement path at the movement speed. During a movement of the vehicle device, a network quality in the space is measured according to a measurement frequency to generate network quality data. Whether the network quality in the space is changed is determined according to the network quality data. Whether there is an obstacle around the vehicle device is detected. When it is determined that the network quality in the space is changed or the obstacle is detected around the vehicle device, at least one of the movement path, the movement speed, and the measurement frequency is adjusted.
