The process of shooting panoramas with fisheye lenses involves a number of considerations and they are as follows To shoot quality degrees panoramas with fisheye, it is imperative to get the equipment as well as the set up right. Your equipment needs to be calibrated properly to make the stitching process nice and easy. To find the best setting for your equipment, the grid method is recommended on the panohead.
Other than setting up and calibrating the equipment in the right manner, it is important to keep the camera steady and leveled as you make the rotations to take shots.
For leveling, it is recommended to use an appropriate leveling base, while for rotation, using a panning clamp on top of the ballhead is highly recommended. For a full frame camera with 15mm fisheye lens in the portrait position, you will require a total of six shot rounds and 1 up to complete a full sphere.
If you were using a crop-sensor camera, you will need to have a 10mm fisheye lens to achieve the same sequence. With this method, there will be no need for a zenith shot and you can easily patch the tripod spot when editing in Photoshop. In normal photography, it always pays to remember what to include and what to exclude in your shots.
When it comes to shooting s, it becomes more complicated since everything is included.Ballistic fabrication 4 link kit
For you to take successful s with fisheye therefore, you need to consider keenly where you stand. The fisheye lens will introduce a lot of space between you and the subject, hence you must consider how close or far away you are from the subject so that the pieces of the compositional puzzle will fall in place smoothly both in the horizontal and vertical planes.
To stitch s taken by fisheye lenses after shooting, you will need panorama software like Autopano Pro or PTGui. For Autopano Pro, you begin by importing the images into the software and ensuring that the EXIF are displayed correctly on the program. Once the stitching is done, it will be important to present the output online.
This can be done using Pano2VR or you could simply upload the finished panoramas to cities for online viewing. Fisheye lens refers to an ultra wide angle lens used to produce strong visual distortions with the aim of creating a wide hemispherical or panoramic image.
Fisheye lenses are able to achieve very wide angles of view not through the production of straight lines of perspectives, but through a special mapping which makes the resulting images have the characteristic convex non-rectilinear appearance.
The term fisheye was started by American Physicist and inventor Robert Wood in and it was in reference to how a fish would have an ultra wide hemispherical view while swimming deep in the waters.How can you do this? By choosing a video editing software with the right tools and features for video editing. We can now record the world in degrees, but using a camera can be much more than just a capturing the footage. More and more, savvy video editors are investing in cameras with the aim of capturing impressive footage.
Creating that perfect video begins with getting that great footage with your camera, but ends with the right video editing software to bring everything together.
Turn your footage from your camera, into video to be proud of! Correct color, add transitions and trim video and more! To get started - let's check out this great video of one of the 7 wonders of the world - the Grand Canyon.
With video you do not have to worry about not capturing the right angle - because it captures almost every angle. You do have to remember that everything around your camera will be in the video, the detail of every room, the camera operator, any equipment or cords. If you are holding it by hand - be prepared that your face will always be in the footage. Your camera may have come with different types of mounts - if the right one is not there, checkout Amazon to see what camera accessories are available.
Looking to create real estate video to showcase a house? This real estate agent has set up the camera on a tripod in the middle of each room to allow the user to explore the house, room by room. They have then trimmed and edited the video together to allow the user to spend 30 seconds in each room to explore and move around freely.
The benefit of video is that the potential house buyer can explore freely and move around the environment as they wish. When you export your video from your camera, if you are using a video device chances are it is already in one of the popular monoscopic formats: equirectangular, spherical fisheye or dual fisheye. When you play it back on your computer's default video player example Windows Media Playeryour footage does not look right because this is not a video player.
Below is likely one of the views you are seeing when you open it in a standard video player:. Just like a world map - this format flattens the spherical experience into a rectangular format - the above picture if of a straight dock but format flattens it out so you can see both in front and behind you. This is the native format that video is edited in. Although it projects a cool image, this format gets converted for playback and editing.Which translates to 4k domemaster resolution.
In my opinion this makes for a heightened immersion experience. So I was on my own to figure out the potential problems, shooting subtleties, and overall workflow. This can be a tedious and nerve-wracking process. After all, with 10 GoPro cameras shooting in unison, something is bound to go wrong at some point. So alas, plan within plans within plans, theorize contingencies, and take notes of your experience.Amazing Simple Trick to Shoot Better Panoramas
And now for you brave souls remaining, below are my own findings, tips, and thoughts. Update: December 13, — Recently I have been contributing to the Making open source book. So if you find this blog post helpful, then Making will give you a comprehensive understanding. There are different mindsets and considerations depending of what action you are performing.
But having the plastic rig locked onto a tripod helps. I chose to permanently install the aluminium mount so that 7 of the GoPros are looking at the horizon. Since I shoot for a dome, this can ease stitching pains later on since often the objects of interest are in these camera zones.
This leaves 1 camera pointing straight up and 2 pointing down at the tripod. Interestingly, if a camera fails then I can trade it out for 9 or 10 and still not lose any essential zones. So there is some redundancy there. Also, removing the cameras from the rig is difficult due to the tightness of the plastic camera clamps. If a camera begins to act strangely then I can easily trace it back to the source.Diagram based 2005 pacifica fuel filter completed
This is rare, but can happen if the video frame is of a pure blue sky with no overlapping content to match up. The first time you setup the cameras, you will need to setup the default video recording settings for each camera by hand. From that point forward the cameras will remember those settings.Most cameras with two lenses have unstitched files that are double circular fisheye format, either as separate files as in the case of the Virb raw files or as a single video as in the Samsung Gear or Xiaomi Mijia Mi Sphere.
Most cameras have stitching apps, but some do not, and sometimes there is a need to use third party stitching software. Radu has used this software to stitch videos from the Xiaomi for example. Here are the steps:. If you have a separate video for the front lens and the rear lens, proceed to step 3.
If the video from both lenses is in one file, you need to split it into two separate files. There are many ways to do this, such as by cropping a video or by using Adobe Premiere Pro as shown by Radu in his tutorial. You need to fix the metadata in each video file. To do that, open each file in Pixpro desktop desktop software by clicking on the hard drive icon in the Pixpro software. Set the mode to global and export.
Launch Pixpro 4K Stitcher and open the files you exported from Pixpro software. Adjust the lens calibration by adjusting distance, etc. You should have a fully stitched equirectangular video.
Note: Radu will make another version of this tutorial that uses Davinci Resolve. When he has the video, I will update this post.

Hi Tony. Ulf Brusquini has been able to stitch at full resolution with Muvee stitcher. Also, does Dashwood have stitching tools? Hi John.I was challenged to see if I could create degree view panoramas from a series of fish eye images taken at right angles to one another working from this tutorial. I modified the code from my lens dewarping project to create the code for this project which you can check out here.
There are roughly two types of fisheye images, circular fisheye lens that map a sphere onto the image plane, and full frame fisheye lens that map the input image to the entire rectangular image plane. The data I was working with was from a circular fisheye, which is significantly easier to reason about. There are a couple of different ways you can approach the problem of fisheye lens dewarping.
The first, and probably more robust approach is to develop a camera lens model that accurately represents the fish eye lens distortion, and apply that lens dewarping to the image.
The second, and in my opinion the easier, albeit slightly less robust approach, is to create a mapping from the output image pixels in terms of phi and theta in a circular coordinate system, and map that to pixels in the input image.
The basic idea is that in the output image each pixel represents some steradian on the input image. Each steradian then maps to a point on the image plane, which you can calculate by doing a spherical to Cartesian conversion and dropping the value that is in the normal to the image plane.
Dewarped image on the left and input circular fisheye image on the right.

For example, in my code, I first create an output image and assume each x and y position on the image maps to somewhere roughly between 0 and degrees 0,pi for both phi and theta. In my model the direction pointing straight out of the camera is called y, so I then do a spherical to Cartesian conversion assuming a unit sphere.
Since the unit sphere is at the origin, I shift the sphere and rescale it to be of unit length, and then multiply the result by the input image dimensions. An easier way to think of it is this:. The map is a bit tedious to create, but once you have it, OpenCV can really quickly push pixels around and give you a result. The next step was to do the panorama stitching. To do this I first matched ORB keypoint between two successive pairs of images.
Since I knew the images were vertically aligned, all I needed to calculate was the x value that is the horizontal offset. I then used this x offset to construct an alpha mask that I could use to smoothly blur the two images together.
I played with this for a little while and I found a nonlinear mapping seemed to work a lot better. You can follow any responses to this entry through the RSS 2. About Curriculum Vitae. The entire process as one big image.

It works and is friendlier than hugin but you still need to fix the seam line in PS, Affinity or Pixelmator. It IS fast though!
Spoke to soon!
Works on images crashes every time with video. Still not bad if you work mostly with images though! Not as good as the Xiaomi PC stitcher but sooo much better than Muvee.
It stitched this scene almost without any fails. Thanks to Mic and Hanz Aart for the tip!! I was too fast…. So I have to take the rekommendation back until that issue is fixed. Hi Ulf!
