How to make vr

According to the equipment you use, you need to use different methods to shoot, but in short, you need 360 plus two worlds to see around (full-frame camera +8mm fisheye can not shoot the world).

Before shooting, you need to have a full understanding of your own equipment, whether it is the whole picture or C, the focal length of the lens is very important for your shooting.

Step one:

Choose a more suitable point.

The so-called more suitable points mainly include: places with complex ground (simple ground is convenient for repairing the ground later), places where the contrast between light and shade is not very strong, and places where people flow less. This is not necessary, but it is necessary to make shooting easier and reduce the workload in the future.

Step two:

After selecting a good point, it is necessary to horizontally place the virtual reality tripod head on the bracket (in fact, the camera can also be tilted to a certain extent, and the Ptgui can also be adjusted internally, but why not do it at once), and initially install the camera.

After installing the camera, you need to adjust the pan/tilt to the state shown below, and then choose the angle of each rotation according to the camera configuration. Generally speaking, panorama camera +8mm fisheye rotates 90, and SLR camera +8mm fisheye rotates 45.

Step 3:

This step is also the most critical step: adjust the camera node.

Camera nodes are very important for panoramic shooting on the ground. Many people just think that the camera node is the center of the camera, but it is not. The nodes of the camera are related to the camera body and the lens used. Generally speaking, the nodes will be on the lens body.

Step 4:

After adjusting the camera node, it's time to start shooting.

Many people will ask this question, how many good photos should be taken in a circle? There is no fixed answer to this question, it depends on your equipment parameters.

In fact, there is no need to mechanically understand the shooting of virtual reality panorama.

You can remember one of the following principles:

1, regardless of horizontal (row) or vertical (column), ensure that adjacent photos overlap at least 30% to 45%;

2. If the visibility of the scene is low (such as white walls), the overlapping part can be appropriately increased, but the maximum is not more than 50%;

Here is the use of fisheye lens. It is recommended to use 8mm fisheye lens with Quan Huafu SLR camera, which will make shooting very simple. You only need to shoot four shots in four directions, east, west, north and south, and you can shoot the whole world or not.

If the 8mm fisheye lens is matched with a C-format SLR, you need to take four more shots at each 45 angle, that is, eight shots in a circle. Note that when using a C-frame camera, you should shoot the sky and the earth, because CMOS is smaller than a full-frame camera, and the shooting range will be smaller. If you don't shoot heaven and earth, it will be very troublesome.

Other fisheye or wide-angle ultra-wide-angle lenses will definitely take more photos, because there must be a certain degree of overlap.

Be careful not to move the tripod when shooting, and make the rotation angle accurate to the predetermined position every time (the current panoramic pan/tilt has various angle parameter contact settings, which can make the rotation angle reach the contact accurately and feel the touch, which is why I always recommend using panoramic pan/tilt instead of spherical pan/tilt).

Step 4:

That's it for today!

In fact, it is very simple to take a panoramic view, that is, rotate the camera around the pan/tilt. It is said that complicated node adjustment and light processing are also very complicated.

Photography is not only a technical job, but also an arduous job. Photography is both simple and difficult. Only by continuous progress, continuous learning, continuous improvement and continuous improvement can we achieve Excellence.
