MMM-Face-Reco-DNN - All new Face Recognition

ChrizZz

I have a new strange error and I think it’s just if I restart mm with “pm2 restart mm”. If I reboot my pi, everything is fine.

I get this too, when my PI can’t connect to the camera. I know that, because if i use
Raspistill -o s.jpg
I will get an error there too. A reboot seems to fix it though. I don’t know what makes it happen, but i suspect the cable.

@Blauenfeldt the python code returns an error, but the module does not expect it, and fails.

rjlinden

Will this work if the camera is rotated? If not, can you tell me where I need to change the code?

Hi,

when im trying to install the face_recogtnition I’m getting this error code:

Does anybody know how to fix this/what is causing this?
Sorry if it’s obvious, im a super noob with this kind of stuff

Cheers

Try this :

pip --no-cache-dir install face_recognition
-python setup.py install

What is the best camera for this module ?
Pi NoIR Camera V2

https://www.raspberrypi.org/products/pi-noir-camera-v2/

Or

Camera Module V2

https://www.raspberrypi.org/products/camera-module-v2/

Thanks for advance :)

@gaudouy
Thank you, seems like that worked.

But now I am getting following error when I’m trying to run “encode.py”

Python 3.7.3 (/usr/bin/python3)
>>> %Run encode.py
Traceback (most recent call last):
  File "/home/pi/MagicMirror/modules/MMM-Face-Reco-DNN/tools/encode.py", line 5, in <module>
    from imutils import paths
ModuleNotFoundError: No module named 'imutils'
>>>

But when I’m installing “imutils” using “pip install imutils” I am getting no error, but following message:

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: imutils in ./.local/lib/python2.7/site-packages (0.5.3)

Any Idea how to fix that?

And to your best camera question for this module, I’m using the PiCamera Module v.2, but I can’t tell you how good its working, since the Face-Reco is not working yet…

@nischi
First off, I love your module. Well done. Its lots of fun.

Question - How can I display the frame/view of the camera on the magic mirror?
I would like to see what the camera sees on the screen in Magic Mirror. So I can see the display and the little green boxes with the names of the faces it recognises. Do you know what I would need to do to display the camera frame with the facial recognition code running the scans/outputs on screen?

@nischi If a user who isn’t known by Face-Reco-DNN moves in front of the camera, is a notification message generated and picked up by MMM-MotionControl? It doesn’t look like the “default” and/or “everyone” classes toggles the screen to un-blank. I was expecting that ANY motion (changes in the capture frames from the camera) would un-blank, but I’m not seeing this behavior. No log-in message gets written to the log.
