General • VIA VL 805 Chipset
Hello
This is my report about my experiment for VIA VL 805. I use 2 usb host controller with this chipset. And based on my research, still have bad frames in great number and frame drops. Camera is Visible, though. I use 10 meters usb 3.0 cable.

I think the problem is the driver from VIA itself, beside must be installed in Win 7 compatibility, it also have reconnecting issue, if you installed without win 7 compatibility.

General • Re: Dual Kinect 2's on same machine?
A quick update:

I received the USB 3.0 Expresscard for the laptop last night.

I can get a Kinect 2 to work with the Expresscard, along side a second Kinect 2 plugged into an on-board USB 3 port. Unfortunately, the frame rate for the sensor on the Expresscard is too low, ranging unsteadily at around 24fps. That's significantly faster than what I was seeing before but still not good enough for recording mocap. So, it's back to using a single Kinect 2 for this laptop.

Oh, well...the Expresscard only set me back about $24, so it's not a big loss. Actually, it may not be a loss at all because adding this controller expands my mobile capability for PS3 Eye cameras, and I may revisit using a PS3 Eye setup later this year. If I can find a faster compatible ExpressCard, I may try multi-Kinect 2 on this computer again.

So, next up: by sticking with the 'one Kinect 2 per computer' rule, I may be still be able to capture with three Kinect 2 sensors using my other hardware options. TBD.

I still haven't tried a multi-Kinect 2 setup with my re-built desktop workstation. Hopefully, my USB 3.0 card from the old workstation is compatible with the new motherboard. I'll give it a try in the next couple of days.

Will keep posting as things develop so stay tuned!

Cameras • Re: Best height for 6-8 PS Eye cameras?
Quote:

So if I understand correctly, the cameras should generally be 1-1.5m, with every 4th camera at a greater height of 2-2.5m. We have 8 PS Eye cameras here - is there a benefit to mounting all 8, as opposed to 6, as far as capture quality? Any other tips would be great!


The heights don't need to be so specific; the heights you use should depend on the motions you're capturing. In a nutshell, the camera heights are staggered to improve coverage, and some motions benefit from different coverage angles.

Also, staggering the camera heights makes it easier for iPi Mocap Studio to identify each one when calibrating the scene. So it's NOT a good idea to use the same heights for multiple cameras.

When positioning the cameras, go for the best visual coverage of the action you're trying to record. The example vmaslov gave is a good one: if the performer is lying down on the floor, then having the camera higher up allows them to see more of the the motion than if they were all at eye level or lower. If the performer is mainly standing, then favoring eye level positions is better. You still want to stagger the heights though and make the positions obviously different for scene calibration.

That said, this does not mean you should move the cameras for every capture. Try to plan your motions so similar performances can be recorded together. Then, when there is a drastic change, decide if you need to move the cameras and re-calibrate the scene.

Because of this, I don't recommend mounting the cameras in permanent room locations. It's more flexible to use tripods and other move-able camera mounts.

General • Re: Tracking props?
Our software only tracks body, not props. Motion controllers are used to improve orientation for joints which can be poorly determined from a video. So you can use our tracking only for an attached prop when its orientation/position is linked to one of body's joints.

Cameras • Re: Best height for 6-8 PS Eye cameras?
Hi
The general rule of thumb for color cameras is placing one per each 4 at a greater height of 2 - 2.5m and others at 1 - 1.5m.
However, for specific motions other setups may be more beneficial. For instance, when an actor is lying on the floor or crawling, you can improve tracking quality by placing more (like half) cameras higher, up to the ceiling level.

General • Re: Tracking props?
Hello

I'm new here. Sorry for reviving old post. I have several question for tracking props, for example: guns/knife. I already have 6 PS3 Eye but didn't have PS move yet. My questions are:
1. For tracking props (Guns, Knife or maybe flower vase), that lying on the floor or maybe situated in some tables or cabinet. How to track them? If i want to make a pick up mocap session?
2. Or maybe toss them around?
3. Is it possible in Ipisoft to make this scene. Example: A soldier shooting an assault rifle then throwing a grenade to enemy position, or maybe just simple scene like taking an ammo magazine from soldier pouch and attach it to his AR.

Thanks for asnwering

Cameras • Best height for 6-8 PS Eye cameras?
Is there any info regarding the best heights the PS Eye cameras should be mounted when setting up mocap? The iPi Soft user guide has suggested heights for 3 camera setups, but nothing beyond that. We are setting up a studio space with 6 to 8 cameras. Thoughts?

Yes, NEC chip is the safest choice for additional USB 3.0 controller.

General • Re: Dual Kinect 2's on same machine?
Ok, I think this card might work:

1 Port Flush Mount ExpressCard SuperSpeed USB 3.0 Card Adapter with UASP Support

This one has Renesas/NEC chips, which I believe are more likely to support Kinect 2.0. Is this correct? Just looking for an opinion before ordering it.

Confirmed, it's an ExpressCard slot! Now I need to figure out which card works with Kinect2 and Recorder.

General • Re: Dual Kinect 2's on same machine?
Ugh...too busy this past weekend but still looking into this as time permits.

Re: the laptop, I noticed last night that there is slot in the side of the computer that looks like an ExpressCard slot. If this is the case, adding a second USB 3.0 controller might solve my dual Kinect 2 framerate issue on this computer.

Trying to confirm what this slot is now, and then I need to figure out which USB 3.0 ExpressCard works with the Kinect 2. I see a lot of options for Laptop USB 3.0 ExpressCards on Amazon. Does anybody have a recommendation for Kinect 2 compatibility?

Thanks in advance for any helpful advice.

Issues • Re: Dual kinect - one kinect not recognized
Hi
No we did not experience this exact issue. But we experienced other issues with certain USB 3.0 chips or when connecting multiple Kinects to a single USB 3.0 controller.
So you're trying to run on the desktop, right? Which USB 3.0 controllers it has?
Are you sure there are no any issues before recording starts - like low frame rate or frame drops? You may stay at Setup stage for prolonged period and check statistics.
Which driver do you use for Kinect - UsbDk or libusbK? In any case you may try another one to see if it helps.

Issues • Dual kinect - one kinect not recognized
Hello everyone,

I've tested today the new release version of Ipisoft,with the awesome upgrade of recording with 2 kinects for one pc only! I connected my 2 kinects, everything was going well. Lauching IpiRecorder, and calculating background, without any problems. But, when I click on "Record", I have an error message, "could not load any device". One kinect works fine but the other is no longer recognized everytime I try to record the motion.

Did you have this trouble too ? I tried with my laptop and all went successful.. I've been searching all the afternoon for an issue, testing the USB 3.0 ports, the kinect cable... Can't find a solution yet =(

Thanks in advance for your help !

General • Re: Dual Kinect 2's on same machine?
Quick followup:

Nothing conclusive yet. I only had time to try two Kinect 2 sensors with the laptop. This wasn't a full test, I literally just plugged two Kinect 2 sensors into the USB ports to see what would happen.

It was cool to see both devices appear in Recorder but I couldn't maintain a suitable frame rate with both sensors at the same time. I tried some obvious optimization tricks, like disabling video and trying different usb ports, but that didn't help. That's about as far as I got but there's still a few things I can try when I have more time to investigate.

TBH, I wasn't too optimistic that this would work with the laptop. My guess is that I need a separate USB 3 controller for the second sensor, which isn't going to happen with this laptop. It still might work but I think I'll have better luck with the desktop workstation, which does have a second USB controller.

My system specs in a nutshell:

The laptop is a Lenovo Thinkpad P71 Xeon 32GB with Nvidia Quadro P4000. It's a beefy system and I hoped this would be powerful enough but maybe not for two Kinect 2 sensors. The USB controller is Intel and I believe there's more than 1 USB 3.0 controller but I haven't figured out how the ports are divided yet. Something I still need to play with.

The desktop computer is a home-built i7 Coffee Lake 6-Core 64GB with Nvidia GTX970. I think this computer has better chance of working with the dual Kinect 2 setup. I'm not sure what USB controller is on the motherboard but it's probably Intel. I have another non-Intel USB 3.0 controller in this computer, so I'm not sure how that will go. It worked with Kinect 2 when I had the old motherboard and processor in this box. I'll probably need to get a new one simply because it's a really, REALLY old card. TBD.

Both computers are running the latest Windows 10 Pro.

Tips for anybody trying this for the first time:

- As mentioned earlier, you need to install the UsbDK software first. This allows the Kinect 2 sensors to connect to iPi Recorder without using the Microsoft Kinect 2 SDK.

- If the MS Kinect 2 SDK is installed, you'll need to disable it from inside Recorder, and make sure the multi-Kinect driver is enabled. On my system, both were shown as Active after installing the update, and only one Kinect 2 window was visible in iPi Recorcer. After disabling the MS entry (just click on it,) both sensors became available in Recorder.

- Disable any devices that appear in the window that you're not using.

Hope this helps.
