带有树莓Pi3的网络摄像头使用googlecloudvision检测物体

Question

我想把USB网络摄像头和Raspberry Pi3集成在一起，并将捕捉到的图像发送到Google Cloud Vision来检测物体。有没有python3库可以做同样的事情？

我已经成功地集成了我的网络摄像机，并且能够使用"Motion"在URL上传输视频

任何类似于Pi相机的库或者可以让我从上面提到的运动库向前移动。会有很大的帮助。在

pygame.camera.init()
pygame.camera.list_cameras()

    pygame.image.save(img, file)

    pygame.image.save(img, "img_captured.jpg")
cam.stop()

credentials = GoogleCredentials.get_application_default()
service = discovery.build('vision', 'v1', credentials=credentials)

with open('img_captured.jpg', 'rb') as image:
    image_content = base64.b64encode(image.read())
    service_request = service.images().annotate(body={
        'requests': [{
            'image': {
                'content': image_content.decode('UTF-8')

    response = service_request.execute()

    try:
        label = response['responses'][0]['logoAnnotations'][0]['description']
    except:
        label = "No response."

    print("Detected  >" + label)
