okiee, thanks for letting know.

This question can be closed now.

How can I mark it as resolved?

jakaskerl thanks Jaka, I'll add the code.

so what is the return value for USB3 and USB2?

@erik

Here it is:

[ 270.646853] usb 1-1.2: USB disconnect, device number 8
[ 271.418559] usb 1-1.2: new high-speed USB device number 9 using xhci_hcd
[ 271.519513] usb 1-1.2: New USB device found, idVendor=03e7, idProduct=f63b, bcdDevice= 1.00
[ 271.519534] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 271.519542] usb 1-1.2: Product: Luxonis Device
[ 271.519548] usb 1-1.2: Manufacturer: Intel Corporation
[ 271.519554] usb 1-1.2: SerialNumber: 18443010F1F1071300

@erik yep, after looking around, I found the Y adapter might be the thing to solve the issue.

For USB 2, I do not know the OAK-D Lite camera has booting. I thought the booting is only for POE model?

But mine is not POE model.

What does Discovery here mean?

How to find out whether it is the discovery or booting?

Hi there,

I use a USB 3 Cable connects to the USB3 socket(the blue ones) on RPi 4, but somehow the system still recognizes the device as a USB2 device:

[ 270.646853] usb 1-1.2: USB disconnect, device number 8
[ 271.418559] usb 1-1.2: new high-speed USB device number 9 using xhci_hcd
[ 271.519513] usb 1-1.2: New USB device found, idVendor=03e7, idProduct=f63b, bcdDevice= 1.00
[ 271.519534] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 271.519542] usb 1-1.2: Product: Luxonis Device
[ 271.519548] usb 1-1.2: Manufacturer: Intel Corporation
[ 271.519554] usb 1-1.2: SerialNumber: 18443010F1F1071300

How can this be fixed?

Hi there,

Appreciate if you could help.

I have code that works on OAK-D with external power supply but does not work on OAK-D Lite.

I have the question posted in an earlier post but it has been closed without a solution, so I thought posted here again:

I am using the Original Official RPi 4 Power supply:
Which has 5.1V and 3.0A.

RPi 4 OS Details (64 Bit):

PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"

NAME="Debian GNU/Linux"

VERSION_ID="11"

VERSION="11 (bullseye)"

VERSION_CODENAME=bullseye

ID=debian

Error Message:

Here is the dmesg from my RPi:

I can see that the OAK-D Lite recognized using the USB as USB2 not 3. However, I am using a blue USB3 cable.

In my code, I use the OAK-D like to do a NN network, Depth Calculation(on camera).

So how can I make the code also work with OAK-D Lite?

Also, I found that the OAK-D Lite and OAK-D cameras are always recognized as USB2 device even I use the blue USB3 cable comes with the OAK-D camera.

How can we solve this issue?

Hi erik

I need the same code to work on Oak-D Lite camera. How can I achieve that?

The Oak-D camera works with an external power supply and USB cable, but the Oak-D Lite camera does not have the socket for an external power supply.

erik

Thanks Erik for your help.

I also observed that the image seems left-right flipped. Am I right? How to fix this issue?

jakaskerl hi could you please try it on OakD lite version?

How do you want to see the disparity from my camera? Just display it in picture or paste the data of the disparity here???

Hi there,

I notice that by using the SpatialLocationCalculator to calculate the depth on the camera(OAK-D Lite), most of time, it will return distance 0 for the last row on an image, please see the image below:

Is it something wrong in the API or my code?

Here is my code:

Not a problem at all

hi erik thanks for your timely update.
Excitingly, after I fixed a few other places, it finally works now_!

I have created a PR for this.
https://github.com/luxonis/depthai/pull/446

I hope to contribute to this great project

Cheers,

Winston

thanks erik for clarifying the installation. So I just need to install the depthai 2.9.0.0 and this lib will contain OCP and OP.

Okay, so after I installed it and a couple of other dependencies(including setup the USB rules) and I ran:

$ python3 depthai_demo.py -cnn deeplabv3p_person

/usr/lib/python3/dist-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.26.6) or chardet (3.0.4) doesn't match a supported version!

So this is the error I got. Could you please help?
Btw, my python3 is 3.7.3

Many thanks,

Winston

Morning erik Now I understood, I can install

1. Depthai 2.9.0.0
2. opencv-python 4.4.0.46
3. opencv-conrib-python 4.4.0.46

I have checked the Github code for DepthAI and still cannot find the version 2.9.0.0. So I hope the version 2.9.0.0 of DepthAI(DAI) will be compatible with the 4.4.0.46 of both opencv-conrib-python(OCP) and opencv-python(OP).

thanks erik so "that version" means the version for opencv-python, right?

And if I understood you correctly, I won't need the opencv-contrib-python right?
It would be a great relief if I didn't need to install one more hard-to-install package haha.

Thanks
Winston
