Usually, VR is presented as a display tied to the head, with which you can step into a new world and enjoy unforgettable impressions. This enveloping VR property allows you to explore the environment at 360 degrees, but for most people, this new creation is a mystery. That’s why we decided to tell you more about the virtual reality world.
Now VR is at the beginning of its journey, methods of shooting and transformation of the footage just begin to appear. Usually to remove the 360-degree material the operator uses several cameras installed in a spherical shape to capture the entire scene. Each camera is set at an angle to capture the field of view of other cameras. This is done so that operators can get the picture without any spaces.
But besides the quality of camera shooting, its placement also plays an important role. Depending on what the creator wants, the position of the camera may vary. Should users be members or viewers? Should they look at the picture from the height of their height or below? Although designers will eventually place the camera in the right way, it is important to remember that a properly installed camera will give a more correct result.
Volumetric photogrammetry as one of the methods for creating a virtual environment
Consider the volumetric photogrammetry. This method of creating a virtual environment contains the key to the future of VR. Unlike the method mentioned above, there is no volumetric filming, which is later edited in post-production. This allows you to create much more dynamic events, the user is given freedom of action. When using the method of volumetric shooting, the cameras record the movements of a real person and translate it into a 3D image.
Volumetric VR reveals the main characteristics of photogrammetry using the principle of triangulation. This method includes shooting from at least two points, just as we see the world with two eyes to get a three-dimensional image. This method is widely used in video games, for example, in Star Wars.
Photogrammetry is, in essence, a still image processing method for creating a high-resolution 3D mesh. There are several approaches to processing, but they all include shooting the subject in real life and launching it through special software. After the image is captured, the software will create anchor points, more or less connecting points, that is, it will create a complex structure that can be used to create environments with lower resolution.
