The present disclosure provides a method and apparatus for determining a pose of a tracked object in an image tracking process. In this method, a current frame of image and first point cloud information corresponding to the current frame of image are acquired, the first point cloud information being based on a relative relationship between an image capture device and an ambient space: and a pose of the tracked object in the current frame of image relative to the image capture device is determined according to the first point cloud information and object feature information of the tracked object if the tracked object is in a static state, the object feature information being based on a relative relationship between the tracked object and the ambient space. In this method, by using the first point cloud information to convert the relative relationship of the tracked object, it facilitates determining the pose of the tracked object.

The present disclosure provides a mobile power supply and a method for supplying power to a peripheral device. The mobile power supply comprises a first peripheral connection port and a second peripheral connection port, a first group of connection-port processing circuits and a second group of connection-port processing circuits, a control circuit, and a power supply circuit. A control strategy determining circuit in each group of connection-port processing circuits determines a voltage adjustment strategy according to power supply status information of a corresponding peripheral connection port. The control circuit then causes a voltage adjusting circuit in the connection-port processing circuit to adjust, according to the voltage adjustment strategy, a voltage output by the power supply circuit, such that the adjusted voltage is used to supply power to a peripheral device coupled, by means of a power supply terminal, to the peripheral connection port.
