Embodiment Construction

[0049] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0050] Specifically, a mixed reality video recording method based on OpenVR comprises the following steps:

[0051] S1, creating a virtual camera driver script to generate a VR application program;

[0052] S2, correcting the parameters of the virtual camera;

[0053] S3, fitting the real camera image to the virtual camera, and outputting the mixed reality video.

[0054] Preferably, the virtual camera driver script described in step S1 is created to generate a VR application program, including the following sub-steps:

[0055] S11, when developing VR projects based on Open VR and Steam VR, embed third-party virtual camera support components;

[0056] S12, create a new empty object in the scene, and pass this empty object as a...

Abstract

The invention discloses an OpenVR-based mixed reality video recording method, comprising: creating a virtual camera driving script to generate a VR application program; correcting virtual camera parameters; fitting a real camera image to the virtual camera, and outputting a mixed reality video. Correcting the virtual camera parameters includes the following steps: open the calibration program, select the corresponding supported image input device, and adjust the image parameters; specify the type of accessory currently used to locate the virtual camera position, and confirm that the corresponding device status is connected; The calibration program prompts to confirm the close-range and long-range marked points, so as to automatically generate the correction parameters of the virtual camera; after the parameters are adjusted, export the current virtual camera parameters and store them in a file. The invention has the advantages of good compatibility, low hardware requirements, simple implementation steps and wide application scenarios.

Description

technical field [0001] The invention relates to the field of video technology, in particular to an OpenVR-based mixed reality video recording method. Background technique [0002] With the re-emergence of virtual reality (VR) technology and acceptance by the general public, games, training, and education in virtual reality have become an increasingly common way of life. Compared with traditional interactive methods, Virtual reality content has the advantages of high fidelity and high immersion, but due to its fully enclosed audio-visual sensory separation, the interesting experience of participants in virtual reality is an inexplicable dance in the eyes of others. To make up for this defect, mixed reality (Mixed Reality, MR) video recording technology came into being. The current mainstream mixed reality recording method is derived from the four-frequency recording method supported by SteamVR: in addition to the two control handles, a handle or locator is added in the posit...
