I found a GoPro Omni / Freedom360 clone for around $26! How does it perform?
360 camera rigs are still one of the preferred choices for 360 video production because of their high image quality. However, besides the cost of the cameras, the rigs themselves can be costly. The popular GoPro Omni rig for six GoPro cameras, for example, costs $1199 (the price includes a case and a couple of tools). It actually used to cost $1499.
However, some 360 rigs are now being mass produced, driving down the cost. Recently, I posted about the Selens rig, which is all-aluminum and costs under $100.
I found a rig that costs even less — just $26 (+ $5 shipping). It finally came in the mail yesterday and I got to try it out.
Like the GoPro Omni, this rig uses six cameras, but there are important differences. First, it uses cameras with their waterproof housings. This means the rig is waterproof / splashproof (although videos shot underwater will not be stitchable due to refraction). So, it’s actually much more similar to a Freedom360 F360 Explorer, another popular rig.
Second, the GoPro Omni is designed to place the lenses of the GoPro cameras close to the middle of each face of the cube, which would facilitate stitching. This rig has the housing in the middle of each side, so the lenses are not exactly in the middle of each face. (This is also true for the Freedom F360 rig.)
Third, because this rig uses action cameras with housings, it seems possible to use it with other cameras with GoPro-style mounts, not just GoPro Hero cameras.
Fourth, the GoPro Omni is made of aluminum, whereas this one is made only with 3D printed plastic parts. Nonetheless, it seems reinforced with bolts and is rigid, with no flex in the frame. It’s kind of hard to see in the picture, but the holes here show long metal bolts that have been inserted into the frame to reinforce it.
The rig has two positions where you can place the tripod mount – either on the bottom, or on top (to use the rig hanging down). There’s an adapter to allow you to use it for a 1/4-20 or 3/8-inch tripod / stand.
As I mentioned, the cameras are attached with their waterproof housings. The rig doesn’t use the GoPro style screw, which have handles too long to fit in the frame. Instead, the housings are secured by bolts with philips heads and hex nuts (the bolts and nuts are included). To tighten the bolts, there are holes through which you can insert a thin screw driver (included).
The rig has flanges that act as backstops against which the housings can rest to achieve a consistent position.
I tried attaching a GoPro Hero4 waterproof housing, a GoPro Hero5 frame, and a waterproof case from an SJ5000X action camera. They all appeared to fit. However, I found that for one of the camera positions, the camera is barely resting on the flange, so you’ll have to be more careful positioning. The other camera positions were fine.
I don’t have six GoPro cameras, so to test whether the rig produces a stitchable image, I instead took photos with a GoPro Hero5 Black at each of the positions. This isn’t a perfect test because the rig can get nudged to different positions as I transfer the camera from one position to the next. Nonetheless, when I imported the photos into Panoramastudio Pro, it was able to stitch them. Here is the alignment before stitching:
Note: there are seven shots instead of six because I took two shots for one of the positions. I made a small adjustment to give a better alignment for one of the cameras before stitching it.
Here is the stitched photo:
As you can see there are some stitching errors, but the errors seem likely to be fixable with more careful positioning of the cameras (again, I was moving the camera from one position to another, which likely made the stitching much worse than it would otherwise be). From this brief test, it does appear that this $26 clone of the GoPro Omni / Freedom F360 Explorer may be usable as a 360 camera rig. I got the rig here on eBay from this seller.
Can you upload somewhere those unstitched photos and give here a link? I wish i could try to stitch them myself and check my stitching skills 🙂
OK Kuba, when I get home. I will post a link.
That would be an interesting “just for fun” contest. Post six (or whatever) photos that you’ve successfully stitched but were tough to get a decent stitched 360. Let the contestants download the photos and stitch. See who comes up with the best and quickest result. Post what stitching software was used. Prize would be the admiration of their fellow stitchers. Good way to test stitching software, too.
Well wrote Bill, let’s wait and see if we can stitch those photos better 🙂
Hi Kuba. Sorry I haven’t uploaded the samples! I’ll do it tonight for sure!
Here’s the link https://drive.google.com/open?id=0B4RnW2_ZeadSMUNmOW9OODlQSE0
OK Bill. We can do that!
Me and my software failed with this challenge ;(
Manual stitching in Ptgui went horrible wrong, so I tried Autopano and here is the result -> https://roundme.com/tour/191627
This thing is worth its price – imho quality not even close to PanoHero or other much better made Gopro rigs.
I also tried PTGui and it also got mangled. But PanoramaStudio Pro got me the results that I showed. Autopano result is not bad at all compared to PanoramaStudio Pro!
I also used PanoramaStudio Pro. It easily identified the control points. And got close on the first render. But I had to set multiple manual image alignments to get this final, still not perfect result. Then I gave up after about an hour. https://kuula.co/post/7lkmB
I have used this rig before. I 3D printed mine and assembled using bolts as you stated this one is. The rig is most certainly useable. Things to consider though: 1. this is no where near as durable as the Selens aluminum mounts 2. the alignment can and most likely will be very difficult to get “perfect” 3. since the mount isn’t very rigid it seems very likely that the mount can flex while recording depending on how it is being used.
I certainly understand that this is a very inexpensive way to mount the cameras, remember how much money in cameras you are mounting to a piece of PLA plastic that can easily break sending your cameras to… well wherever amazing place you are shooting.
Oh I forgot to mention, if you have access to a 3D printer and would like to try this bad boy the files are available on the Thingiverse (as well as other interesting 360° mounts and accessories): https://www.thingiverse.com/thing:1304353
Thank you very much Brad! I agree, if someone were really serious about shooting, they probably should get the Selens instead of this 3d printed one. For me, it was just an interesting experiment. 🙂
Hi. Will this fit the hero 2 enclosure? I think the only difference is that the hero 2 enclosure is thicker.
Sorry i don’t know.
