To shoot a panoramic footage we need to use a number of professional equipment.
Digital SLR camera
Fisheye lens
Panoramic head
Tripod
Finally, let's look at how to generate 360 panoramic images using stock footage
Step 1: Shooting panoramic raw footage
By a professional photographer with a professional camera, a fisheye lens, and a tripod. Take photos of cars, rooms or other objects that need to be displayed in 360 panorama
Let's look at the three spare raw materials
Step 2: Use "PTGui Pro" software to synthesize panorama pictures
Download "PTGui Pro" software (download it here). Pro" software (download address) and install it, then open the software:
According to the prompts, click on "Load Image", and import the original panorama material as follows:
----------
Next, click on "Align Image". "Align Image"
If the image is taken in the right place, the software will go directly to the panorama editing process
Usually, we don't make any changes to the image here, and just close the editor to go to the next step of "Creating Panorama". "
Sometimes the image is not so accurate, so we need to adjust the image manually
As shown in the picture:
We need to compare the left and right images, and find the overlapping points on the image (at least 3 points) to mark
As shown in the picture:
On the picture above we have A **** find a number of points where the two images overlap and mark them, and so on, you need to mark at least 3 "control points" for all the images that may overlap.
----------
After adjusting the image, we can create a panorama
Set the directory of the output file, click on "Create Panorama", and we have a processed panorama.
Look at the panoramic picture we got:
This picture is the so-called "panoramic picture", see very dizzy, it does not matter, it is still only a half-finished product, through the third step, we will further process this picture to generate the effect of a beautiful 360 panoramic display effect
---- ------------------------------------
Step 3: Use "Pano2VR" software to realize the 360 panorama effect
Download the "Pano2VR
Download the "Pano2VR" software (download address) and install it, then open the software:
In the picture above, click "Select Input" to import the panoramic pictures generated in the second step; at the same time, click the drop-down box of "New Output Format" and select "Pano2VR". drop-down box, select the "HTML5" option, and then click the "Add" button
As shown in the figure
Click the Add button to get
Set the size of the cube sheet to 700
Set the output directory of the output file, and then click OK. After setting the output directory of the file and clicking OK, the 360 panorama effect will start to be generated
Open the output directory and we can see
At this time, the browser will automatically open the .html file in the above picture, and the 360 panorama effect can be appreciated
Please remember to set the 6 files in the "images
Please remember to upload the 6 pictures in the "images" directory to the server of Weimeng through the location of uploading panoramic pictures in the background of Weimeng, then you can view the 360 panoramic effect through your mobile phone
