Problems solved by technology

However, the existing UE4 engine cannot load both head modules (the head module of the head-mounted display device and the head module of the HMD positioner) at the same time, because it is not clear which head module controls the camera pose
Therefore, mobile virtual reality devices with positioning functions cannot be implemented based on the existing UE4 engine

Embodiment Construction

[0043] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The UE4 engine is an engine for developing games, which consists of different functional modules. For further instructions on the engine, you can refer to the following link: http: / / api.unrealengine.com / INT / index.html . Since the head interface IHeadMountedDisplay provided by the UE4 engine needs to control the attitude of the camera, and the HMD positioner does not need to control the attitude of the camera, the attitude of the camera is expected to be controlled by the IMU in the mobile head-mounted display device (such as GoogleVR, GearVR) to develop VR At this time, the head module injected by the HMD locator into the UE4 engine cannot implement the head interface provided by the UE4 engine. It is necessary to customize a head interface. This interface does not control the attitude of the camera, and then...

Abstract

The invention discloses a virtual reality scene implementation method based on a UE4 engine, and a system thereof. The virtual reality scene implementation method comprises the following steps: injecting an HMD module of virtual reality equipment into a UE4 engine; creating an HMD calling interface for an HMD module of the virtual reality equipment in a UE4 engine; and when the UE4 engine loads the virtual reality equipment, acquiring a position interface and an attitude interface of an HMD positioner of the virtual reality equipment by calling the HMD calling interface, and controlling the state of the camera through the position interface and the attitude interface of the HMD positioner. The virtual reality scene implementation method effectively solves the conflict problem of loading the HMD locator head module by the UE4 engine. The HMD module of the virtual reality device is injected into the UE4 engine so as to be called during use, and the requirement of the mobile terminal virtual reality device for obtaining the spatial six-degree-of-freedom data based on the UE4 engine is met.

Description

technical field [0001] The invention relates to a method for realizing a virtual reality scene based on a UE4 engine, and at the same time relates to a corresponding virtual reality scene realization system, belonging to the technical field of virtual reality. Background technique [0002] A head-mounted display device (abbreviated as HMD) is one of the important links to realize virtual reality technology. Send optical signals to the eyes through various head-mounted display devices, and use binocular stereo vision to make users see different images in both eyes. Usually, one eye can only see odd-numbered frames of images, and the other eye can only see even-numbered frames of images. , using the difference between the odd and even frame images (that is, the parallax) can make the user have a strong three-dimensional sense and achieve a 3D simulation effect. [0003] Currently, images for the left and right eyes are usually generated using the Unreal Engine 4 (referred to ...
