Method and device for playing back recorded video

Abstract

The embodiment of the invention provides a method and device for playing back a recorded video. The method comprises the following steps: loading pre-recorded operation parameter information of a to-be-recorded object, wherein the operation parameter information corresponds to moments corresponding to the frame images respectively; adding the operation parameter information to a three-dimensionalgraphic engine, and playing back and recording a video by utilizing the three-dimensional graphic engine according to the operation parameter information of the frame image at the corresponding moment, wherein the display mode of the image content of the recorded video changes in real time along with the change of the operation parameter information. The device is used for executing the method. According to the method and the device for playing back the recorded video provided by the embodiment of the invention, a user can conveniently and autonomously play back the video corresponding to theoperation parameter information of the to-be-recorded object.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a method and device for playing back recorded video. Background technique [0002] 3D graphics technology has been widely used in various aspects such as scene production, virtual simulation, urban planning, real estate development, cultural relics display, virtual education, traffic design and 3D games, among which the 3D graphics engine determines the quality of 3D graphics applications. The underlying data structures and algorithms required by 3D graphics applications are abstracted into a complete program framework, and a convenient development interface is provided for 3D developers. [0003] For 3D developers, the recording and playback functions of the operating parameter information (such as camera displacement, rotation, and scaling) of the object to be recorded can be realized. When the user needs to record and playback the video corresponding to the ope...

Problems solved by technology

[0003] For 3D developers, the recording and playback functions of the operating parameter information (such as camera displacement, rotation, and scaling) of the object to be recorded can be realized. When the user needs to record and playback the video corresponding to the operating parameter information of the object to be recorded, the user needs to Inform the 3D developers of the above requirements, and the 3D developers will implement them through the 3D graphics engine. Users cannot realize the above functions on the user side, which will bring a lot of inconvenience to users in the process of recording and playback of the above videos.
