Embodiment 1

[0033] The VR immersive application system based on 3D real scene cloning technology solves the problem that existing VR applications have a large amount of data and high requirements on network bandwidth, which may lead to missing data, insufficient scene authenticity, and weak user experience. question.

[0034] VR immersive application system based on 3D real scene cloning technology, such as figure 1 shown, including:

[0035] VR scanning equipment: select multiple display points and connection points to scan and analyze the real scene and send them to the scene acquisition unit;

[0036] Scene acquisition unit: According to the data collected by the VR scanning equipment, use the three-dimensional data stitching technology to stitch together the entire complete scene, and transmit the scene data to the scene storage unit and the scene modeling unit;

[0037] Scene storage unit: Fragment the scene data, slice and divide according to the adaptive size, and then store it i...

Embodiment 2

[0042] In this embodiment, on the basis of Embodiment 1, further, the VR scanning device is a camera based on depth vision technology, collects and analyzes 3D data of a real scene scene, and does not need to perform post-processing when calculating the depth of field after the picture is taken. It can not only avoid delay but also save the cost related to the use of a powerful post-processing system, and the scale of ranging is flexible. In most cases, it only needs to change the intensity of the light source, the optical field of view and the pulse frequency of the transmitter. The camera of the camera is a binocular vision camera, which has two kinds of cameras, one is a color camera, and the other is a depth camera. The color data is collected by the color camera, and the depth data is collected by the depth camera. Wherein, the depth camera is such as a laser radar and Kinect, but the cost of lidar is very high, and it is more used for military or industrial use, so it is ...

Embodiment 3

[0045] In this embodiment, on the basis of Embodiment 2, further, the front-end device is a mobile terminal connected to the cloud server, and the operation gestures of the mobile terminal are integrated to perform interactive operations on the displayed scene model, and the mobile terminal is a mobile phone or a tablet computer. It also includes a VR wearable terminal connected to the front-end device to increase the user's immersive experience.

[0046] This embodiment enables users to experience scene applications on mobile terminals, including barrage annotations, data measurement at key locations, and data display. For example, display the length and width of the room, expand hardware integration, monitor the temperature value of the scene, and view video.

Abstract

The invention discloses a VR immersion application system based on a 3D live-action cloning technology, and belongs to the technical field of virtual reality, and the system comprises: VR scanning equipment which selects a plurality of display points and connection points to carry out the scanning analysis of a live-action scene; a scene acquisition unit which is used for splicing a complete sceneby using a three-dimensional data splicing technology and then transmitting scene data; a scene storage unit which is used for fragmenting the scene data, slicing and segmenting the scene data according to an adaptive size and then storing a single file; a scene modeling unit which is used for establishing a scene model in a ratio of 1:1 with a real scene and transmitting scene model data to thefront-end equipment; and front-end equipment which is matched with the hardware display card, accelerates the hardware display card by using an HTML5 Canvas 3D technology, quickly loads scene model data and displays the scene model data. According to the VR immersion application system, the problems of possible data loss, insufficient scene authenticity and poor user experience caused by relatively large data volume and relatively high network bandwidth requirements of an existing VR application are solved.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, relates to the field of VR immersive application technology, in particular to a VR immersive application system based on 3D real scene cloning technology. Background technique [0002] VR technology, also called virtual reality technology, includes computer, electronic information, and simulation technology in one, and simulates the virtual environment through computer to give people a sense of immersion in the environment. In recent years, VR technology, as a new field of science and technology, has been gradually gained It is widely used in film and television, virtual reality games, painting and other scenes. [0003] At present, there are many VR applications based on 360-degree panoramas on the market, such as VR photos or VR videos. VR photos generally stitch multiple flat pictures into a whole 360-degree panoramic picture and show a panoramic effect based on this, while videos Mor...
