Problems solved by technology

However, since the monitoring area is in a safe state most of the time, it is easy for the security personnel who observe the images for a long time to reduce their vigilance, and it is difficult to maintain a high degree of attention to the images in the monitoring area
If the security personnel ignore the suspicious person appearing in the image, or the speed of the security personnel adjusting the controller of the PTZ camera cannot keep up with the moving speed of the suspicious person, it will easily lead to insufficient clarity of the picture of the suspicious person captured by the PTZ camera

Embodiment Construction

[0018] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the camera 100 of the present invention. The camera 100 includes a pan / tilt / zoom (PTZ) drive unit 10 , an image capture unit 20 , a control unit 30 , a processor 40 and a memory 50 . Wherein, the image capture unit 20 includes a lens 21 and an image sensor 22 for capturing continuous images of the surveillance scene, and the image sensor 22 focuses on the surveillance scene through the lens 21 . The image sensor 22 can be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).

[0019] The PTZ driving unit 10 includes a P motor 11 , a T motor 12 and a Z motor 13 , which are respectively used to drive the lens 21 to move horizontally, tilt a certain angle and adjust the focal length of the lens 21 .

[0020] In this embodiment, the camera 100 is a time-of-flight (TOF) camera, which is used to capture scene images within the scope of the surveillance scene a...

Abstract

The invention provides a camera and a control method thereof. The camera comprises a memory, a driving unit, a lens and a control unit, wherein the memory is used for storing a three-dimensional human-like image and a three-dimensional human face image; the control unit is used for comparing and analyzing a scene image shot by the camera with the stored three-dimensional human-like image as well as detecting a three-dimensional human-like region in the scene image; the driving unit is used for driving the lens to correspondingly move, adjust the focal length and shoot to obtain a distinct three-dimensional human-like image; the control unit can be also used for comparing and analyzing the distinct three-dimensional human-like image with the stored three-dimensional human face image as well as detecting a three-dimensional human face region; and the driving unit is used for driving the lens to correspondingly move, adjust the focal length and shoot to obtain a distinct three-dimensional human face image.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a video camera and a control method thereof. Background technique [0002] Traditional PTZ cameras with Pan / Tilt / Zoom functions must rely on security personnel to keep an eye on the images of the surveillance area in order to be able to control the situation in the surveillance area. When security personnel detect suspicious characters appearing in the image, they can only manually adjust the controller of the PTZ camera to adjust the lens angle and focus to obtain a clearer image of the person. However, since the monitoring area is in a safe state most of the time, it is easy for the security personnel who observe the images for a long time to reduce their vigilance, and it is difficult to maintain a high degree of attention to the images in the monitoring area. If the security personnel ignores the suspicious person appearing in the image, or the speed of the security personnel adjusting...
