Abstract: The application provides a method, a device, and a non-transitory computer-readable storage medium for simultaneous localization and mapping initialization. In the method, an operation of removing influence of rotation is performed to a predetermined number of continuous frame images that are obtained, and then initial key frames are screened, with a pre-built adaptive-sized sliding window, from the predetermined number of continuous frame images after the operation and the initial key frames are used for initialization.

Abstract: Embodiments of the present disclosure provide a video processing method and device, and an electronic device. The method includes: acquiring a first video frame to be processed; segmenting the first video frame to acquire a patch corresponding to a target object and a patch region; acquiring position information of three-dimensional points within the patch region, and determining, according to the position information of the three-dimensional points within the patch region, three-dimensional position information of the patch; displaying, based on the three-dimensional position information of the patch, the patch at a position corresponding to at least one second video frame.

Abstract: The disclosure provides a method, device and storage medium for back-end optimization of simultaneous localization and mapping. In the method, a target three-dimensional space point is determined in three-dimensional space points of a plurality of key frames located by a simultaneous localization and mapping system. In addition, a reprojection error is determined based on the target three-dimensional space point, and a weight is provided for the reprojection error by preprocessing the maximum parallax corresponding to the target three-dimensional space point, to obtain the relative reprojection error.
