Detu Max just launched on Kickstarter. It’s an 8K 3D with an embedded AI chip. When you hear the price, you’ll get sticker shock — not because it’s so expensive but because it’s so affordable: $2199! (FYI, the next lowest price for an 8K 3D 360 camera is the Obsidian at $6999…!) But the price is NOT its killer feature. Find out what makes Detu MAX unique and game changing for professional 360 cameras!
Detu is a company that has produced several 360 cameras, beginning with the hemispherical Detu Sphere, then the higher resolution Sphere S. It was later followed by the Detu F4, one of the first 6K 360 cameras. At CES 2017, they announced two cameras: the Detu Twin and the Detu F4 Plus (at that time known as F4 Pro), currently one of the most affordable 8K 360 cameras at $2599. Then at CES 2018, Detu launched their new flagship 360 camera, the Detu MAX with 8K 3D 360 video and an embedded AI chip. Here’s a quick preview of the Detu Max, its features and capabilities.

Detu Max’s most important feature is its stitching. All 360 cameras have a minimum stitching distance. Objects that are nearer to the camera than the minimum stitching distance will have very significant stitching errors. For 3D 360 cameras, this is an even more challenging issue because they have to have sufficient distance between the lenses to have a noticeable a 3D effect, but at the same time, the larger the distance between the cameras, the greater the potential for parallax stitching errors. For this reason, 3D 360 cameras usually have large minimum stitching distances. For example, the minimum distance for the Insta360 Pro is around 5 feet.
Detu Max’s minimum stitching distance is 1.1 inch, according to Detu. That is unheard of and if it is true, it makes the Detu Max usable in many situations that would be impossible for other 3D 360 cameras. Here is a sample screenshot showing a subject that is very close to the camera, and yet is stitched correctly, and has a good 3D effect:
You can check out the sample videos below to see more examples that convincingly demonstrate its remarkable minimum stitching distance. To me, this impossibly short minimum stitching distance is Detu Max’s killer feature. No other professional 360 camera can be used at such small distances. Practically speaking, the threshold will be the minimum distance for stereo (with a 3D image, if you are too close to the object, it will feel uncomfortable, as if you are viewing something cross-eyed). But you’ll be able to use the Detu Max in almost any situation (within reason). And if you switch to 2D 360 mode, there are even more possibilities.
UPDATE: I’ve had the chance to look at the videos more closely, and it appears true that it has a very short minimum stitching distance in front of the lenses, but the corners have noticeable stitching issues. Actors have to make sure to avoid being along the corner stitch lines.
Detu Max has other features such as HDR mode, and supports RAW and Log mode. It also has livestreaming in 2D or 3D 360.
Detu MAX also has an AI chip embedded in it. The chip gives it additional capabilities such as object-tracking and face recognition. Detu’s representative also showed me a few other things that they are working on for the Max. I saw demos of depth mapping and 6DOF (I assume it was simulated). I also saw that they are planning to use the Max to generate 3D models, with floorplans and dollhouse modes. It looked similar to Matterport or Cupix, with 3D models that seemed to be more detailed than on Cupix. Detu’s representative explained that the app is intended for interior designers, who will be able to use Max to generate 3D models of a location and place virtual furniture in it. If it works as advertised, it does seem like a useful feature.
Detu hasn’t formally posted samples from Max yet but at CES they had a sample 8K 3D 360 video that people could watch with a VR headset. I expect that they will make the video available for download in the future.
The video featured a martial artist doing exercises in a small room. The resolution was pretty good, legitimately 8K. I didn’t have the chance to inspect closely but I thought it looked good, including the colors and dynamic range. The stereoscopic effect was realistic (the lens pairs seem to have a standard interpupillary distance).
What I was most curious about was the stitching. The Detu Max has an uncommon lens configuration with eight lenses in orthogonal directions, similar to Vuze. In the case of the Vuze, the stitching looks smooth in 2D but in 3D, there is a noticeable seam. I wondered whether the Max would have a similar difficulty with stitching. As it turns out, it appears from the sample they showed that stitching actually seemed quite good. What was even more impressive was the stitching at the nadir and zenith, which looked seamless.

PRICE AND AVAILABILITY
As predicted, Detu Max plans to undercut its competitors. It is priced very aggressively, and will retail at $3499, the same price as the Insta360 Pro (reviewed here), which can only do 6K 3D 360. Other competing cameras include the Kandao Obsidian R, also 8K 3D 360 at $6999, and the Z-Cam V1 Pro (7K 3D 360 at $8880). With respect to its AI capability, it would also be competing indirectly with Pilot Era which also uses AI.
For its Kickstarter campaign, Detu Max is even more affordable and is being offered at the shocking price of $2199 for super early bird backers. According to Detu’s CEO, Detu Max will also be offered on its website after the Kickstarter campaign, for a preorder price of $2599.
