Abstract: This application provides a video information generation method, apparatus, and system and a storage medium. The video information generation method includes: obtaining a plurality of temporally consecutive target images; obtaining first information of a target object in the target images; and associating first information of a same target object located in different target images to generate target information. In the video information generation method provided in this application, the first information of the target object in the target images is obtained, and the first information of the same target object located in different target images is associated. In this way, target information with a relatively small amount of data can be obtained, thereby improving the efficiency of remotely viewing a video by a user.

Abstract: A method for assembling a drive system for an escalator system includes securing one or more track sets extending along a path of the escalator to one or more support members extending at least partially across a width of the escalator system. A drive member is secured to the one or more support members such that the drive member is operably connected to the one or more track sets. The one or more track sets, the one or more support members and the drive member are installed into the escalator system as a unit.
