VR panorama production is an increasingly popular technology in recent years, which can bring users a very immersive experience and has a very wide range of application scenarios. VR panorama production can capture offline real scenes into VR panorama images, and through image processing and software stitching technologies, create scene images and interactive interfaces required for VR panorama display.
The process of VR panorama production includes multiple links such as panoramic shooting, image processing, panorama stitching, and production interaction. Next, let’s take stock of the steps of each link:
1. Panoramic shooting
VR panorama production needs to go through multiple steps and processes, and panorama shooting is a very important link, so we need to choose appropriate shooting equipment and shooting angles to ensure the stability and image quality during shooting.
1. Equipment installation: The shooting equipment required for making panoramas includes SLR cameras, fisheye lenses, tripods, panoramic heads, etc. According to different scenes and shooting needs, we can adjust the shooting equipment according to the actual situation. First install the tripod and adjust the tripod to a suitable height. At this time, observe the level of the tripod to ensure that the bubble of the level and the outer circle of the center point are mutually contained and centered; then install the panoramic head and tripod together, and then install the camera and Panoramic head, use the buckle attached to the panoramic head to install the camera on the head, so far the installation of the shooting equipment is completed.
2. Equipment shooting: During the shooting process, by adjusting the pan-tilt base to rotate the platform clockwise, a photo is taken every 60°. Note that each photo must have a certain degree of overlap, at least 20% overlap; Then in the camera's triple burst mode, three photos are taken from each angle. After the photos of the surroundings are taken, the photos of the sky and the earth are taken, and the shooting is considered complete.
2. Image processing
For the pictures taken in the previous stage, first use LR to process the picture, and then use Photomatix Pro to combine the photos in the three-shot mode into one picture, and keep the details of the highlights and shadows, so that high exposure, normal exposure, Composite weakly exposed photos for better exposure.
3. Panorama Stitching
After processing the pictures, the next step is image stitching. Generally speaking, ptgui is used for stitching, and the operation is also very simple. You only need to import the processed pictures into it, and you can generate a stitched panorama with one click;
And for some small flaws, we can use PS to modify them, such as the tripod, the reflection of the glass, the obvious splicing marks, etc. All the disharmonious parts of the picture need to be beautified; then use pano2VR to make the panorama three-dimensional, so that A completed panorama is considered a finished product.
4. Make interaction
In order for users to feel the charm of VR panoramas, we need to create an interactive interface so that users can explore panoramic scenes through interactive operations, such as scene switching, zooming in and out, automatic rotation, etc. We can add arbitrary annotations, annotations, etc., embed graphics, videos, add phone numbers, QR codes, etc. to the panorama.
It is actually not difficult to produce high-quality VR panoramic works. Even novices and novices can get started quickly after a series of training. The main thing is to see what our industry needs are, and add 3D objects, dynamic interactions, and VR according to the needs. Meetings, AI digital human and other functions can make the charm of VR panorama bloom.
