MMM-Facial-Recognition seems to run only once

[d00my]

Hello @all!

First of all - thank you very much for your impressive work you are doing guys! Thank you very much for that.

Now I am playing around with MM2 for 4 weeks and got almost all modules running.

But now I´m facing troubles with MMM-Facial-Recognition. All steps in the readme of the module and module tools (MMM-Facial-Recognition-Tools) are successfully done for the first User.

If I start MM2 on my Raspi 2 all modules are started without an error :

The time between the entry that the Webcam is used and “User undefined logged in” takes about 45 seconds.

Here is the entry of my config.js regarding the MMM-F-R module:

{
			module: 'MMM-Facial-Recognition',
			config: {
				// 1=LBPH | 2=Fisher | 3=Eigen
				recognitionAlgorithm: 1,
				// Threshold for the confidence of a recognized face before it's considered a
				// positive match.  Confidence values below this threshold will be considered
				// a positive match because the lower the confidence value, or distance, the
				// more confident the algorithm is that the face was correctly detected.
				lbphThreshold: 80,
				fisherThreshold: 250,
				eigenThreshold: 3000,
				// force the use of a usb webcam on raspberry pi (on other platforms this is always true automatically)
				useUSBCam: true,		//Original=false
				// Path to your training xml
				trainingFile: 'modules/MMM-Facial-Recognition-Tools/training.xml',
				// recognition intervall in seconds (smaller number = faster but CPU intens!)
				interval: 2,	//Original=2
				// Logout delay after last recognition so that a user does not get instantly logged out if he turns away from the mirror for a few seconds
				logoutDelay: 10,
				// Array with usernames (copy and paste from training script)
				users: ['***'],
				//Module set used for strangers and if no user is detected
				defaultClass: "default",
				//Set of modules which should be shown for every user
				everyoneClass: "everyone",
				// Boolean to toggle welcomeMessage
				welcomeMessage: true
			}
		},

It seems that the settings for recognition interval and logout delay are not interpreted after the first execution:

recognition intervall in seconds (smaller number = faster but CPU intens!)
   			interval: 2,	//Original=2
   			// Logout delay after last recognition so that a user does not get instantly logged out if he turns away from the mirror for a few seconds
   			logoutDelay: 10,

Any ideas what the reason for that behaviour could be?

Output of lsusb:

Bus 001 Device 005: ID 0c45:613b Microdia Win2 PC Camera

Output camera settings:

The functionality of the webcam seems to be okay because I performed some tests with motion.

Every suggestions are welcome!!

Hi @all!

Does somebody have a clue?

Try playing with the threshold. I’ve only used the module with the official pi cam and on my Mac so I cannot guarantee other cameras are working correctly.

@paviro

Hi Paviro!
Thank you for your response. I ordered a pi cam. Lets see what will happen.

@d00my Does it work now? I think I have an similar problem with the PiCam. I start the Magic Mirror and after selecting the camera nothing is happend. It doesn’t try do recognizie any user. I reinstalled all, and it worked ONCE… now I have the same problem like bevor. I tried intervall: 1, 2 and 5.
