python - 在 Django 中运行面部识别脚本

Question

我的 django 应用程序中有一个面部识别脚本，下面是代码，它返回一个字符串，它是找到的人的姓名。当我将图像参数传递给它时，该脚本本身运行良好。我想在我的views.py 中运行这个脚本，所以当我得到一个名字时，我会在我的模型中搜索这个名字然后得到一个匹配的结果。模板加载得很好，但在上传图像后我提交没有任何操作发生。

def identify_face(imagename):
    known_face_encodings = []
    known_face_names = []
    known_faces_filenames = []

    for (dirpath, dirnames, filenames) in os.walk('assets/img/users/'):
        known_faces_filenames.extend(filenames)
        break

    for filename in known_faces_filenames:
        face = face_recognition.load_image_file('assets/img/users/' + filename)
        known_face_names.append(re.sub("[0-9]",'', filename[:-4]))
        known_face_encodings.append(face_recognition.face_encodings(face)[0])


    face_locations = []
    face_encodings = []
    face_names = []
    imagename_new =  face_recognition.load_image_file(imagename)
    face_locations = face_recognition.face_locations(imagename_new)
    face_encodings = face_recognition.face_encodings(imagename_new, face_locations)

    face_names = []

    for face_encoding in face_encodings:
        matches = face_recognition.compare_faces(known_face_encodings, face_encoding)
        name = "Unknown"

        face_distances = face_recognition.face_distance(known_face_encodings, face_encoding)
        best_match_index = np.argmin(face_distances)
        if matches[best_match_index]:
            name = known_face_names[best_match_index]

        face_names.append(name)

    return name

这是我的 forms.py 和 views.py 代码

表格.py

from django import forms


class ImageUploadForm(forms.Form):
    image = forms.ImageField()

视图.py

from .models import MyData
from cisdb.forms import SearchForm,ImageUploadForm
from django.contrib.postgres.search import SearchVector
from cisdb.face_recogniton_script import identify_citizen


def citizen_match(request):
    form = ImageUploadForm()
    query = None
    match = ''
    results = []
    if 'query' in request.GET:
        form = ImageUploadForm(request.GET)
        if form.is_valid():
            query = form.cleaned_data['query']
            match = identify_citizen(query)
            results = MyData.objects.annotate(
                        search=SearchVector('first_name', 'last_name','other_name'),
                        ).filter(search=match)
    return render(request,'match.html',{'form': form,'query': query, 'results': results,'match':match})

匹配.html

{% block content %}
  {% if query %}
    <h3>
      {% with results.count as total_results %}
          Found {{ total_results }} result{{ total_results|pluralize }}
      {% endwith %}
    </h3>
    {% for data in results %}
        <div class="section">
        <div class="container"></div>
          <h4><a href="{{ data.get_absolute_url }}">{{ data.last_name }}  {{data.first_name}} {{ data.other_name }}</a></h4>
        </div>
    {% empty %}
      <p>No matches found.</p>
    {% endfor %}
    <p><a href="{% url "match" %}">Match again</a></p>
  {% else %}
    <h1>Match faces</h1>
    <form action="." method="get" enctype="multipart/form-data">
      {{ form.as_p }}
      <input type="submit" value="Match">
    </form>
  {% endif %}
{% endblock %}

这是我从命令行中得到的全部
