Abstract: A battery carrier apparatus includes a carrier housing, a plurality of compartments, at least one wheel, a control circuit and a status monitoring circuit. The carrier housing is configured to hold multiple battery modules. The plurality of compartments are disposed within the carrier housing. Each compartment is configured for detachably installing a respective battery module. The compartments provide secure housing for the battery modules. At least one wheel is disposed on the carrier housing. The wheel facilitates movement of the carrier housing allowing for transportation of the carrier housing. The control circuit is responsible for managing an operation of the battery modules installed in the compartments. The status monitoring circuit is coupled to the control circuit. The status monitoring circuit detects a status of the installed battery modules and communicates the status to the control circuit for determining a control behavior to manage the battery modules accordingly.

Abstract: 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.

Abstract: A method and apparatus for spatial locating. The method includes: acquiring feature area information and a current image captured by a camera (102); searching the current image for a feature area of an interactive device based on the feature area information, to determine position information, the position information being used to indicate the position of the feature area in the current image (104); determining first pose information associated with the position and attitude of the feature area relative to the camera (106) based on the position information; calculating a re-projection error of the feature area in the current image (108) based on the feature area information and the first pose information; and if the re-projection error is less than or equal to a preset threshold, determining current pose information associated with the position and attitude of the interactive device currently in a global coordinate system (110) based on the first pose information.
