Abstract: This application provides techniques for implementing interactions in games. The techniques comprise in response to detecting that a client device associated with a player enters a plot stage of a target game, capturing a current game picture at intervals of a preset duration; obtaining a screen recording video corresponding to the target game from a video platform; determining a plot video frame that is in the screen recording video and that matches the current game picture; obtaining target bullet-screen comment information corresponding to the plot video frame from the video platform; and synchronously displaying target bullet screens in the current game picture on the client device, wherein the target bullet screens correspond to the target bullet-screen comment information.

Abstract: The present disclosure provides techniques for presenting information associated with bullet screens. The techniques comprise receiving trigger information comprising information of identifying a bullet screen and information of identifying a user who performed a trigger event for the bullet screen; determining a list of jump links associated with the bullet screen based on the information of identifying the bullet screen; determining a tag associated with the user based on the information of identifying the user; selecting a target jump link from the list of jump links based on the tag associated with the user; and transmitting information associated with the bullet screen and comprising the target jump link for display of at least one part of the information in a preset area associated with the bullet screen.

Abstract: Method and apparatus for detecting obstacle based on monocular camera are provided. The method includes: obtaining a target frame image and its adjacent frame image shot by the monocular camera; deleting an unstable feature point from an initial feature point set of the adjacent frame image to obtain a preferred feature point set; dividing a target feature point set to obtain several target feature point subsets; judging whether the target feature point subset corresponds to obstacle based on a change of a distance between points within a ground projection point set of the target feature point subset from adjacent frame time instant to target frame time instant; and determining a union of all the target feature point subsets which are judged as corresponding to obstacles as an obstacle point set of the target frame image.
