How to make a VR panorama How to make a panorama VR?

It gives gamers a more immersive sense of immersion, making the game truly move from flat to three-dimensional.

You can go for some more professional panoramas** to see.

VR is currently the most used in the field of the game is, everyone knows the game, but for the **, and usually seen** will be very different, VR ** can be seen from how to see, I believe there will be a lot of people interested in how to make VR**, in order to help everyone, we only need to follow the steps of making VR** to operate, let's take a look.

Because VR** is different from ordinary**, it needs 360° shooting, so it needs a set of four-way or even all-round cameras, equipped with cameras in multiple directions, and because the lens of the camera needs to be fixed at the beginning, so the movement track of the camera must be set in advance before shooting, which has a great impact on the quality of a VR**.

At present, the more famous VR cameras include Google Yi Jump VR camera, JAUNT ONE VR camera, Nokia Ozo panoramic camera, etc., but ** is generally more expensive.

2. A good shooting environment.

Since it is a 360° shooting, it is natural that there should be no people or things that are unrelated to the content to be photographed during the official shooting.

Therefore, an enclosed environment is very conducive to VR shooting, but this does not mean that all enclosed environments are suitable for VR shooting, and it is also necessary to consider whether the shooting background and the bad environment can bring a sense of immersion to the viewer.

3. Post-production.

If it is a VR with interactive effects, it is also necessary to write a script and rehearse before shooting, and add an interactive node in a certain link, so that you can make a big fuss about the interactive node in post-production and improve the immersion of the viewer.

Generally speaking, after making the virtual effect of VR**, you can choose to output SDI or HDMI signal, and then encode it, and finally review it, and confirm that there is no problem in it, you can choose to upload it to the major **** and share it with others.

I believe that through the above introduction, now everyone knows how to make VR**, although the steps seem relatively simple, but it is recommended that you reserve more VR knowledge, so that you can better solve the problems encountered during production.

Steps to make a VR panorama for filming:

1. Select equipment and shoot**:

At present, in addition to the map and other large platforms that use panoramic cameras to shoot VR panoramas, most individuals or practitioners use SLR cameras + wide-angle lenses or fisheye lenses to shoot VR panoramas for enterprises that need them. The VR panorama is spliced together by multiple **, so there must be a part of overlap at all angles when taking pictures, so as to ensure better operation when splicing.

After finding a fixed spot when shooting, be sure to check the details such as the camera and gimbal scale when placing the tripod and gimbal, and then choose the number of shots for different focal length lenses.

2. Splicing and beautifying**:

All scenes can be exported after shooting**, and can be stitched directly in batches using the software, or manually processed for each scene and each scene individually.

At present, most of the software on the market is a Chinese cracked version,If you want to learn, choose one of them,Then take a look at the tutorial to practice familiarity,After splicing**The general requirement is 2:1 ratio, the minimum resolution4000*2000**,At this time, you can use ps to beautify the splicing after the completion of the splicing,Modify the flaws。

3. Select the VR panorama processing software platform

In the second step, after splicing and beautifying, the ** is not a real VR panorama, and it needs to be uploaded to a professional VR panorama processing software or platform to see the effect. In addition to providing smooth storage and sharing, the VR cloud panorama production platform also provides the most basic class production functions of VR panoramas, and has special requirements for VR panoramas, such as inserting viewing angles, hotspots, sand tables, masks, **, **, ** and other functions in the panorama, Jiushang VR cloud platform also provides these functions, which are incomparable to general free software.

After doing these three, basically a complete VR panorama will come out, and after uploading to the Jiushang VR cloud platform, you can also share the VR panorama with friends for friends to enjoy, and for professional practitioners, you only need to share the link to the customer. In addition, Jiushang VR cloud platform also has all the tutorials on shooting and making VR panoramas, and you can also take a detailed look at them if you are interested.

The purpose of today's article is to popularize the VR panorama production process for Xiaobai.

There is no doubt that VR has become one of the hottest technologies in the past two years, and both game manufacturers, mobile phone manufacturers, and even operators have enthusiastically joined the competition in this industry. Obviously, these companies are interested in the prospect of VR, and for most people, although they cannot participate in the competition in the VR industry, it is okay to learn how to make a simple VR panorama first.

First of all, we need to prepare the following equipment:

Camera, tripod, gimbal.

When we are ready, we need to choose a location, which is usually in the middle of the scene to be filmed, so that we can take a full picture of the surrounding area. Secondly, lighting is also very important.

Set up the gimbal and camera:

Aperture, shutter, the mystery of ISO.

I believe that after reading this table, you should have a preliminary idea of how to debug the camera, as for how to shoot well, more important practice and time accumulation. In short, because of the special requirements of VR panorama, we should debug the camera based on the brightness and clarity of the picture, if the shooting scene can not meet the requirements, it is best to choose a good weather or lighting and other ways to make up for it.

Take a picture of the sky and directly below the camera**, then directly below the camera**, then aim at the front of the subject, from left to right or vice versa, every 60° interval.

Post-production: Post-production usually uses photoshop and other processing tools, but for novices, and even some experienced professionals, it is also difficult to use the plane phase mechanism as a VR panorama, and it takes a lot of time. For example, Coolman is one of the best VR panorama production companies in the industry.

The panorama production can be roughly divided into three parts (the content comes from the official website of Cool Lehman).

Material collection method:

At present, there are two ways to shoot panoramas, one is head-up shooting on the ground, and the other is aerial photography.

We take aerial panoramas**, currently mainly using drones, we use DJI-based

The SDK's third-party software for automatic shooting, usually takes 24-28 shots** for flattening, and each angle shot** needs to have overlapping areas.

In order to avoid missing some angles, the actual number of shots will be 2 times or more than the final number used. Because of the different angles of view, the X3 needs to shoot about 3 times, and the X5 needs to shoot about 4 times to get it.

Pro(X5), bracke**, took about 110-120 shots** for flattening.

Shooting angle: Panoramic aerial photography is not just a matter of letting the aircraft rise into the air and taking pictures casually. Photographers need to think about the relationship between the shooting point and the subject, how high the camera position is used to express the content and results, and try to find a suitable height and angle with the aircraft to express the content.

When it comes time to take panoramic aerial shots that show the urban planning, we usually fly higher and shoot farther away from the complex. When aerial photography shows the panorama of real estate development, we usually shoot the aircraft at the height of 3 4 of the building, and shoot to the side of the building, so that the building looks more upright and three-dimensional.

Post-editing: Post-collage, generally using PTGUI, is a user interface of a multi-functional panorama maker. panorama

Tools is the most powerful panorama tool out there, but it requires the user to write script commands to work. And PTGUI has done this by creating a tool for panorama (panorama

tools) to provide a visual interface to achieve image stitching.

Shooting panoramas especially requires retouching, a lot of ** stitching. Depending on the occasion and result requirements, we may use fisheye for shooting or medium telephoto for matrix paneling.

Using a fisheye lens can make you work more efficiently, and you can record a scene with less shot. Using a medium telephoto for panoramic photography, you need to shoot more shots** to record a scene, and the **pixels obtained** should be larger, the larger the pixels, the more space in the post.

Another part of the post-editing process is to change the day. For the spherical map of the sky, it is recommended to have at least 15,000 pixels, use a medium telephoto lens, and stitch together multiple images. We often shoot in open areas or high points when the weather is good to collect sky dome maps.

5.Outdoor panorama shooting tutorial.

You can go to the official website of Cool Rayman to take a look, and there are a lot of production tutorials for panoramic VR.

Panorama shooting is nothing more than using a DSLR plus a fisheye lens or directly using a panoramic camera, and then shooting a total of six 360-degree views, and finally adding two photos of the sky and the earth. This is how the pre-shooting is done, and the post-production is to use PTGUI, Cool Lehman, PS and other platforms for splicing.

If you want to make it, you need to use the camera to shoot, and then use ps, ptgui and other software for synthesis in the later stage, what you need to learn is the panoramic shooting skills and the operation of the post-production software, you can find a professional to take it.

VR panorama production is not friendly enough for novices, and there is a certain degree of difficulty, especially in the case of self-shooting + post-production.

You can choose to use some platforms such as Thunderman and follow the tutorial first.

Buy a fisheye lens or panoramic camera first, then you can choose aerial photography or ground photography, and finally use platforms to carry out and achieve trips, such as Cool Rayman, PS, PTGUI, etc.

The panorama production is shot with a camera in the early stage, and ptgui is used for compositing in the later stage, you can go to the official website of Cool Lehman to see the tutorial.

You can use PTGUI software to make it, and the specific operation steps are as follows:

1. First of all, be prepared to shoot from all angles.

2. Secondly, open the PTGUI software, you can see that the interface is very simple, click "Load**".

3. In the pop-up window, select the location where the panorama is stored, open the folder where the panorama is located, select all**, and then click "Open".

4. After opening, ** will be loaded into the software, click "Align Image" below, and the software will analyze, align and stitch all images.

5. After aligning the image, the software will automatically stitch**, and show the spliced **, if the shooting camera position is not greatly moved, the splicing will not be misplaced, so the early shooting is also very important.

6. Click "Create Panorama" in the software, and the software will automatically save the current spelled ** to the panorama source file folder.

7. Finally, go back to the source folder and you can see the panorama that has been made.

1. Equipment preparation.

Different from ordinary panoramas**, VR panoramas are commonly used with shooting equipment such as SLR cameras, fisheye lenses, panoramic gimbals, tripods, etc. The function of the panoramic gimbal is to help us keep the horizontal and vertical shots without offset, and it is also convenient to better control the angle between each shot**. Fisheye lenses can reduce our shooting work with the help of a wider angle of view, and the ** that may need to shoot 5 shots may only need 3 shots with the blessing of fisheye lenses.

2. **Shooting.

Since it is a panorama, it is definitely necessary to shoot the surroundings, and VR panoramas generally include upper and lower perspectives. The first thing we need to pay attention to is the reserved part of the splicing between the adjacent ones, which can facilitate our later splicing, which is generally reserved about 30%; That is to say, only 70% of a ** is really not covered for display. It is also necessary to pay attention to the things that should be avoided in the scene, and remember not to make them appear in more than one ** at the same time; At the same time, there may be different light and dark between each angle due to the influence of light, which also needs to be handled with great care.

3. Splicing processing.

**After the shooting is completed, you need to use the **processing software to adjust,To avoid**There are flaws in it,The most common processing software is PS,And for other processing such as color grading, you can adjust it yourself according to your needs。 Then we generally use PTGUI here, which is also the most popular splicing software on the market, which is simple and powerful. It should be noted that after the splicing is completed, if there are splicing traces, it is necessary to use ps for processing.

4. Add a build.

After the splicing is completed, it can be added to the VR panoramic production platform for generation, and it is recommended to use the Cool Lehman platform here, which has comprehensive functions and has a special corresponding marketing function for merchants. After uploading, click Add Work to achieve the effect of VR panorama, and then you can add functions according to your needs.
