120fps Global Shutter 3D Stereo USB Camera, 1200P Synchronization Dual Lens Module, M9 Mount USB 2.0 Plug and Play for Face Recognition, QR Code Scanning, 3D Printer Golf Swing

Love the form factor, plug and play was great. And I like how it outputs a single video with left and right sides, which handles all the synchronization. This is so much easier than fancier cameras like Zed. But the big problem is the picture quality and lack of adjustment. There was a major fisheye effect on the images. Images need to be rectified so a proper point cloud can be made. The ability to adjust exposure would be good, and there needs to be a way to get the camera intrinsics matrix. I'm not sure what the use cases are for others, but for serious robotics and computer vision, this won't cut it. If the manufacturer can fix the image distortion issues, ensure proper factory calibration (so important), and give sample code for getting point clouds, they would have a very attractive product that they could charge way more than $80 for

Camera worked as expected. It should be treated more as a dev kit than anything else. The system is bare bones so you will have to calibrate the system to generate intrinsic and extrinsic values. Once calibrated and rectified the system performed well using OpenCVs Stereo SGBM class. If your expectation is to get a system that will generate a point cloud out of the gate, this isn't for you. You'll need to understand some CV basics to get this setup working properly.

First the good. You open the package, pull out the camera set which are soldered to a motherboard, plug in a USB-C plug on the top, plug the other end into your PC or Mac and launch your video capture software. The camera shows up as a source called 3D camera, you select it and there you go - it'll automatically capture side-by-side stereoscopic video. If you take said video into a video player on a headset (in my case, a Meta Quest3), you can in fact play it back in sterioscopic 3D meaning, you see it just like you would any other 3D video. The ability to do that without any fancy effort, otherwise, is pretty amazing. Having said that, there are some drawbacks which, given the price, which is close to three digits, I feel I should point out. First, low light is grainy. You can still see perfectly fine but the quality is greatly diminished. The effect is very much lower-end webcam footage when not using this in a brightly lit area. What you're getting here is the raw board. You'll need to come up with your own solution for housing and mounting this. I get that it's meant as a project camera set and might just as well be used in a robot using sterio vision for navigation as it is for a webcam or some other similar usage but for the price, some sort of optional housing or even pointing to a place where you could find a file to 3D print your own would have been nice. I'm taking measurements and am going to be designing my own to 3D print. Lastly, the port is located on the top. When taking it out of the box, you really can't tell which way is the top and which is the bottom but once plugged in, I realized I had it upside down holding it with the plug on the bottom. This is kind of a minor thing but when thinking about cable management for just about any project, can you think of a time you'd have wanted something like this jutting out of the top of things? Having said all that, it does capture fast frame-rates and the ability to combine the two video feeds onboard whatever chip this has before sending it to any computer as a single feed is impressive. Because it does all of this right from the hardware, there are no plugins or special drivers needed for it to work - it just does and that alone is an impressive feat. Again, though, just understand when ordering this that you're not getting a complete product, you're getting a motherboard with two cameras on it and a plug. It'll be up to you to figure out how to mount/house it all and what you're going to do with it.

This camera works without installing special drivers. It acts as a simple webcam and all apps that work with webcams will work with it. The camera takes the two images and puts them side by side so the software sees one camera, with the two frames on the two sides. This gives some weird aspect ratios, and some webcam software balks at the odd resolutions, for instance 640x240, which is two 320x240 images, side by side. The camera is "upright" when the USB c connector is up, and in that orientation the right camera is shown on the right, and the left camera shown on the left. This means you can't cross your eyes to view the 3D effect as that places the wrong image into the wrong eye - use the webcam utility to mirror the image and though it's backwards it does yield a decent 3D effect. The lenses are fixed focus, about 1-2 meters away, and there is no autofocus or shake compensation. The lenses are fisheyed, so you'll need to do a lot of correction in software to extract a usable 3D image. The distance between the cameras is 60mm - close enough to human distance to be useful for 3D viewing. The USB serial number is not unique, so you will not be able to identify which camera to open if multipl cameras of this type are connected. You can find them via their USB connection on the USB tree, and that's about as good as youlll get for knowing what camera you're using at a given time. Helpfully the USB descriptor is "3D USB Camera" so it's easy enough to find if you don't have more than one of this type attached. It connects at USB 2.0 speeds, and doesn't have or use USB3 support, so 480Mb/s is the maximum data rate. Sufficient for its maximum resolutions and frame rates. Here's the USB hardware report: Product ID: 0x2b10 Vendor ID: 0x32e4 Version: 2.12 Serial Number: 01.00.00 Speed: Up to 480 Mb/s Manufacturer: 3D USB Camera

I have no need for a dual lens facial recognition / 3d QR code scanner, so maybe that's the application this is targeted for. I have made some pretty silly clips for VR glasses and 3D TVs that can convert side by side images to left/right polarization (I happen to own one made by LG - and have a few 3D polarized glasses around the house). My 7 year old loves to use his minecraft sword - he's a huge fan of the game - to swipe towards the cam: and it definitely looks like its coming at you. But note, the lenses have to stay pretty stationary for the visual tomfoolery to work. Any movement where the lenses are adjusted to an angle and moved throughout a room (I rooted an old tablet and attempted to mount the cam to see if we could get some "on location" shots going down the slide in his treehouse) can throw the effect off pretty quickly. So while I've enjoyed making 10 second videos, I might not be the best audience for other applications where this might be extremely useful. Nevertheless, we've both had a lot of fun spending some father / son time making the 3D "sword or soccer ball at the camera" vids - and that's priceless.

The quality from these stereo cameras is pretty good. You get two 1600x1200 images at 60 FPS, although I don't see where anyone one would need more than one. The problem I have with these cameras is that I cannot use only one camera. Both cameras show up as a singular camera in Windows, so your programs will use both images as one. Something like OBS can crop one off, but that's just OBS. You'll need virtual software to take split the input of this camera and one of the cameras show up to your programs. Sure, this isn't made to be a Windows webcam, but the manual has no support or any information on how to change any settings. The video quality looks good as a video, but a still image taken from it is on par with a 2015 phone. I recommend these cameras if you know what you need it for. I could see it being useful for a robot or something of the sort.

So, brief rating. This is a bare circuit board, as shown. Don't expect to just use this as a webcam. This came decently packaged, and has a USB A to USB C cord. (I'm not sure why C to C wasn't included, or also included, but... *shrugs* Did some testing on a Windows 11 PC. The camera was picked up instantly, no fuss, no muss. (Or should I say both cameras were?) It does come with suggested apps for Windows, Mac, Linux and Android listed in its instruction manual. The Windows default "Camera" app picks up the cameras and gives a stereoscopic view. By default its face recognition is on - and working. It tracked me fairly well and fairly consistently. It seemed to record movement reasonably well also. The lenses are very "fisheyed," though. It's not particularly noticable in the center, but it becomes more prominent very quickly. So, it's a neat little stereo camera, with several possible uses. I just have to decide on a use myself.

This 120fps 3D Stereo USB Camera is like having the eyes of a cybernetic superhero. Equipped with a global shutter and dual lenses, it captures the world with the precision of a Swiss watchmaker on espresso. The 90-degree, no distortion view is so clear, you’ll start to question reality. Perfect for face recognition, QR code scanning, and making your computer feel like it’s part of a sci-fi movie. Plug and play means no headaches - just instant visual brilliance. It’s so good, your webcam might develop an inferiority complex. Great for use in robotic projects when distance to object is crucial.

This duel camera buying Utterly waste of money. Bad picture quality. Video center horizontal line. This camera can't read barcode.
