Abstract: The present disclosure discloses a method for refreshing screens of a head-mounted display device, a head-mounted display device, and a non-transient computer readable storage medium configured to store computer instructions. The specific implementation is as follows: from a first time point to a second time point, sending first data to both the first screen and the second screen, and writing the first data to the first screen, with the first screen configured to be in a black screen state, and the second screen configured to be in a bright screen state for at least part of the time; and from the second time point to a third time point, sending second data to both the first screen and the second screen, and writing the second data to the second screen, with the second screen configured to be in the black screen state, and the first screen configured to be in the bright screen state for at least part of the time to display the first data.

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.
