Abstract

The utility model provides an intrusion detection device, which belongs to the technical field of public security. The intrusion detection device comprises a passive infrared detection unit, a camera, a video image analyzer and an alarm unit, wherein the passive infrared detection unit is used for collecting alarm signals of a human body or an animal with vital signs; the camera is used for collecting video images; the video image analyzer is used for analyzing the video images collected by the camera and extracting alarm signals with human characteristics; and the alarm unit is used for analyzing the alarm signals with the human characteristics identified by the video image analyzer based on the alarm signals of the human body or the animal with the vital signs detected by the passive infrared detection unit, eliminating the alarm signals with human appearance characteristics but no vital signs or the alarm signals with vital signs but no human appearance characteristics, and ensuring that identification and alarm are carried out only for an intruding human body, thereby realizing early warning and accurate alarming.

Description

Intrusion detection equipment

Technical field

The utility model belongs to the public safety technical field, relates in particular to a kind of intrusion detection equipment.

Background technology

The principle of passive infrared detector is that human surface temperature and ambient temperature exist difference, when human body moves, the variation that this difference produces can detect by infrared sensor, report to the police thereby trigger, but the object that pet, curtain etc. is had the infrared heat radiation can't normally be discerned, and causes the rate of false alarm height.

Simple employing intelligent video analysis technology, the video image that collects is analyzed, intelligence is analyzed resemblance, can't judge that it still is the object of similar human body that the life object is arranged, and have to shortcomings such as environmental suitability differences, at complex environment, be easy to generate and fail to report and report by mistake, and too responsive for some static scenes, as rocking of light, inverted image, leaf etc., also may trigger false alarm.

So the intrusion detection equipment that wherein a kind of technology of single employing realizes all exists rate of false alarm and the high defective of rate of failing to report.

The utility model content

In order to address the above problem, the purpose of this utility model provides a kind of intrusion detection equipment, has the human body of vital signs or the alerting signal of animal is carried out multiple analysis with the alerting signal with characteristics of human body of video image analysis technology identification and passive infrared detecting unit are detected, to have characteristics of human body's profile but do not have vital signs (as inverted image, light changes, sculpture etc.) alerting signal or have vital signs but do not have characteristics of human body's profile (as pet, flying bird, curtain etc.) alerting signal is rejected, guarantee only to discern, reduce rate of false alarm and rate of failing to report at the human body of invasion.

In order to achieve the above object, the utility model provides a kind of intrusion detection equipment, comprising: passive infrared detecting unit 11, camera 12, video image analysis device 13 and alarm unit 14, wherein

Described passive infrared detecting unit 11 is used to gather human body with vital signs or the alerting signal of animal, and has the human body of vital signs or the alerting signal of animal sends to described alarm unit 14 with described;

Described camera 12 is used to gather video image;

Described video image analysis device 13, be connected with described camera 12, be used for the described video image that described camera 12 is gathered is analyzed, extract alerting signal, and the described characteristics of human body's of having alerting signal is sent to described alarm unit 14 with characteristics of human body;

Described alarm unit 14, be connected with described video image analysis device 13 with described passive infrared detecting unit 11 respectively, the alerting signal with characteristics of human body of described video image analysis device 13 identifications had the human body of vital signs or the alerting signal of animal is analyzed in conjunction with passive infrared detecting unit 11 is detected, and will have characteristics of human body's profile but do not have the alerting signal of vital signs, or have vital signs but the alerting signal that do not have characteristics of human body's profile is rejected, guarantee only to discern warning at the human body of invasion.

Preferably, described alarm unit 13 is an audible-visual annunciator.

As shown from the above technical solution, survey complex technique by utilizing intelligent video analysis technology and passive infrared invasion, to have characteristics of human body's profile but do not have the alerting signal of vital signs (as inverted image, light variation, sculpture etc.) or have vital signs but the alerting signal that do not have characteristics of human body's profile (as pet, flying bird, curtain etc.) is rejected, guarantee only to discern at the human body of invasion, reduce rate of false alarm and rate of failing to report, realize giving warning in advance and accurately warning effect.

Description of drawings

Fig. 1 is the structured flowchart of intrusion detection equipment of the present utility model.

Embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer,, embodiment of the present utility model is done explanation in further detail below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, be the structured flowchart of the utility model intrusion detection equipment, as seen from the figure, this intrusion detection equipment comprises: passive infrared detecting unit 11, camera 12, video image analysis device 13 and alarm unit 14, wherein

Passive infrared detecting unit 11 is used to gather human body with vital signs or the alerting signal of animal, and this is had the human body of vital signs or the alerting signal of animal sends to alarm unit 14;

Camera 12 is used to gather video image;

Video image analysis device 13 is connected with camera 12, is used for the video image that camera 12 is gathered is analyzed, and extracts the alerting signal with characteristics of human body, and the alerting signal that will have a characteristics of human body sends to alarm unit 14;

Alarm unit 14, be connected with video image analysis device 13 with passive infrared detecting unit 11 respectively, the alerting signal with characteristics of human body of video image analysis device 13 identification had the human body of vital signs or the alerting signal of animal is analyzed in conjunction with passive infrared detecting unit 11 is detected, and will have characteristics of human body's profile but do not have vital signs (as inverted image, light changes, sculpture etc.) alerting signal, or have vital signs but do not have characteristics of human body's profile (as pet, flying bird, curtain etc.) alerting signal is rejected, and guarantees only to discern warning at the human body of invasion.

Alarm unit 14 can be an audible-visual annunciator, and can the video image in the alerting signal be sent to subscriber terminal side or with note, multimedia message or E-mail by wireless network, or alerting signal is sent to subscriber terminal side by LAN (Local Area Network) (wide area network), realize the report of alert.

As shown from the above technical solution, survey and the compound recognition technology of intelligent video analysis, only discern, realize giving warning in advance and accurately warning effect, greatly reduce rate of false alarm and rate of failing to report at the invasion human body target by utilizing passive infrared invasion.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
