Configuration

Hi Everyone,

Started to work through DLIB and have the following downpat;

–Config–

camera:

  • platform: ffmpeg
    name: Cam
    input: -rtsp_transport tcp -i rtsp://192.168.50.253/unicast

image_processing:

  • platform: dlib_face_identify
    source:
    • entity_id: camera.cam
      faces:
      PersonA: “C:/faces/a.jpg”
      PersonB: “C:/faces/b.jpg”

–Event–
INFO:homeassistant.core:Bus:Handling <Event image_processing.detect_face[L]: name=PersonA, entity_id=image_processing.dlib_face_cam>

–Data–
http://192.168.50.25:8123/dev-template

{{ states.image_processing.dlib_face_cam }}
{{ states.image_processing.dlib_face_cam.attributes.total_faces }}
{{ states.image_processing.dlib_face_cam.attributes.faces[0] }}
{{ states.image_processing.dlib_face_cam.attributes.faces[0].name }}
{{ states.image_processing.dlib_face_cam.attributes.faces[1] }}
{{ states.image_processing.dlib_face_cam.attributes.faces[1].name }}

case: faces detected and matching sample pictures (faces[] populated)
template state image_processing.dlib_face_cam=2; faces=[{‘name’: ‘PersonB’, ‘entity_id’: ‘image_processing.dlib_face_cam’}, {‘name’: ‘PersonA’, ‘entity_id’: ‘image_processing.dlib_face_cam’}], total_faces=2, friendly_name=Dlib Face cam, device_class=face @ 2018-04-17T21:52:49.987106+10:00>
{‘name’: ‘PersonA’, ‘entity_id’: ‘image_processing.dlib_face_cam’}
{‘name’: ‘PersonB’, ‘entity_id’: ‘image_processing.dlib_face_cam’}

case: faces detected but none matching samples (faces[] empty)
<template state image_processing.dlib_face_cam=1; faces=[], total_faces=1, friendly_name=Dlib Face cam, device_class=face @ 2018-04-17T21:28:40.155448+10:00>

Now i’ve made it this far, and I know where the data is stored, I would like to run an automation trigger on the event fire but need to rotate through the maximum possible number of entries with a for/while loop but also store the positive found names and notify me when detected.

Anyone able to help me (preferably keeping it simple) :smiley:

You’ll probably need appdaemon for this or a custom component. the only looping you can do in home-assistant is with templates. Templates only produce a single value.

3

You could get inventive with scripts and conditions, but it would get complicated quick.

So I’ve gotten to the point that I can pass some info via a script but I can’t manipulate the data passed.
I can’t access the faces[] values calling them directly, any ideas on syntax?
I’ve tried setting the faces array (states.attributes.get(‘faces’)) as a var but I assume it’s being access as a string?

Automation.yaml

  • action:
    • alias: ‘’
      data_template:
      entity_id: image_processing.dlib_face_cam
      testd: ‘{{ states.image_processing.dlib_face_cam.attributes }}’
      service: python_script.test
      alias: Face Recog
      condition: []
      id: ‘1524057389579’
      trigger:
    • entity_id: image_processing.dlib_face_cam
      from: ‘0’
      platform: state

test.py
entity_id = data.get(‘entity_id’)
statess = data.get(‘testd’)
states = hass.states.get(entity_id)
logger.warning(“entity_id Passed = {}”.format(states))
logger.warning(“Array Passed: {}”.format(statess))
logger.warning(“Total Faces = {}”.format(states.attributes.get(‘total_faces’)))
logger.warning(“Friendly Name = {}”.format(states.attributes.get(‘friendly_name’)))
logger.warning(“Faces Array = {}”.format(states.attributes.get(‘faces’)))

Output
