Abstract: The disclosure relates to a positioning method, apparatus, electronic device, head-mounted display device, and storage medium. The method is suitable for a head-mounted display device. The method determines a target joint point when a tracking target enters a tracking blind zone; the target joint point referring to a joint point in a wearer's body that supports the tracking target to move within the tracking blind zone; determining position information of the target joint point at current moment; determines relative positional relationship information between the target joint point and the tracking target at the current moment; and determines the position information of the tracking target at the current moment, based on the position information of the target joint point at the current moment and the relative positional relationship information at the current moment.

Abstract: The embodiment of this application provides a method and apparatus for positioning an entity controller, device and a storage medium. The method includes following steps: determining a relative pose relationship between an entity controller and an associated part of the entity controller, the relative pose relationship being determined from at least one entity controller pose and at least one associated part pose, the entity controller pose being determined from a first type of image, the associated part pose is determined from a second type of image, and the first type of image and the second type of image using different exposure policies; determining a current associated part pose, the current associated part pose being determined based on a current second type of image that is closest to the current; and determining an estimate pose of the entity controller based on the relative pose relationship and the current associated part pose.
