VIDEO DETECTION AND ALARM METHOD AND APPARATUS

1 . A method for triggering an alarm, comprising:

obtaining a video feed including a plurality of video frames;

using motion detection to detect a change in the video feed;

using human form detection to detect a human form in the video feed; and

triggering an alarm based on the human form detected.

2 . The method of claim 1 , wherein when human form detection does not detect a human form, the alarm is not triggered.

3 . The method of claim 1 , further comprising:

performing facial detection on an image of the human form to identify the human form; and

triggering the alarm based on the identification.

4 . The method of claim 3 , further comprising:

saving the image of the human form.

5 . The method of claim 3 , wherein the facial detection is used to acquire a facial image of the human form and perform facial recognition of the facial image to obtain facial information.

6 . The method of claim 5 , further comprising:

saving the facial image after the facial image is obtained.

7 . The method of claim 5 ,

wherein when the identification conforms to a predetermined identity criteria, the alarm is not triggered, and

wherein the alarm is triggered when the identification does not conform to the predetermined identity criteria.

8 . The method of claim 1 , further comprising:

saving video frames in which the change is detected.

9 . A video alarm device, comprising:

a first module configured to obtain a video feed including a plurality of video frames;

a second module configured to detect motion and a human form within the video feed; and

a third module configured to trigger an alarm based on detection of the human form.

10 . The device of claim 9 , wherein the third module comprises:

a first alarm prompt submodule configured to not issue an alarm prompt when the result of said human form detection indicates that a human form has not been detected.

11 . The device of claim 9 , wherein the third module comprises:

a facial detection submodule configured to perform facial detection on an image of the detected human form to identify the human form; and

a second alarm prompt submodule configured to trigger the alarm based on the identification.

12 . The device of claim 11 , further comprising:

a first saving module configured to save the image of the human form.

13 . The device of claim 11 , wherein the facial detection submodule comprises:

a first unit configured to perform facial detection on the image to detect and obtain a facial image of the detected human form; and

a second unit configured to perform facial recognition on the facial image to determine facial information.

14 . The device of claim 12 , further comprising:

a second saving module configured to save the facial image after the facial image is obtained.

15 . The device of claim 13 ,

wherein the second alarm prompt submodule is configured to trigger the alarm when the identification does not conform to a predetermined identity criteria, and

wherein when the identification conforms to the predetermined identity criteria, the second alarm prompt submodule is configured not to trigger the alarm.

16 . The device of claim 14 , further comprising:

a third saving module configured to save video frames in which the motion is detected.

17 . A storage medium, comprising:

a computer instruction, wherein when the computer instruction is run, the video detection and alarm method of claim 1 is executed.

18 . A webcam, comprising:

a storage device including a computer instruction; and

a processor configured to run the computer instruction,

wherein when the processor runs the computer instruction, the video detection and alarm method of claim 1 is executed.
