Problems solved by technology

[0003] Even if other software is used to shrink the high-resolution image, reduce the screen resolution, and then perform human image detection, the detection and analysis time cannot be effectively reduced
Because the operation of shrinking and reducing the resolution of high-resolution images also takes a certain amount of time and machine calculations

Embodiment Construction

[0020] Such as figure 1 Shown is a structural block diagram of a preferred embodiment of the camera device of the present invention. In this embodiment, the camera device 2 includes a lens 21 , a memory 22 , a driver 23 and a processor 24 . The camera device 2 includes, but is not limited to, a tour camera that can be driven by software or a hardware circuit, a speed dome camera (SpeedDome) and a PTZ (Pan / Tilt / Zoom) cameras, etc.

[0021] Wherein, the lens 21 is used to continuously acquire images of the monitored object. In this embodiment, the lens 21 is a Charge Coupled Device (CCD). The driver 23 may be a driving motor for driving the lens 21 of the camera device 2 to move.

[0022] The human form detection system 20 is stored in the memory 22, and the human form detection system 20 is used to first detect a dynamic area in the captured image with a dynamic detection technology, and then perform human form detection in the dynamic area, See the specific process ima...

Abstract

A camera device and a method for carrying out human type detection by using the same are disclosed. The method comprises the following steps: acquiring monitored object images continuously shot by a lens of the camera device; detecting a dynamic area in the acquired images; if the dynamic area is detected, using a human type detecting technology to detect a human type image in the dynamic area. By using the device and the method of the invention, a speed of detecting the human type image can be accelerated.

Description

technical field [0001] The invention relates to a camera device and a method thereof that can quickly detect human figures in complex background environments in combination with dynamic detection technology. Background technique [0002] The traditional human-shaped detection method directly detects the human-shaped image in the whole image by using the image of the surveillance object captured by the camera device. In order to enhance the clarity of the image quality, most surveillance devices have increased the resolution of images captured by the camera device. Therefore, if human image detection is performed directly in the captured high-resolution image, due to the large size of the high-resolution image, the required detection and analysis time will be longer. [0003] Even if other software is used to shrink the high-resolution image, reduce the screen resolution, and then perform human image detection, it cannot effectively reduce the detection and analysis time. T...
