Abstract
The invention relates to a safety alarm system, and discloses a control method for a personnel gathering and snapshooting system. The control method for the personnel gathering and snapshooting system comprises the following steps: step 1, video information is collected; step 2, the collected video information is processed; step 3, the collected video information is snapshot, and a high definition photo is formed; step 4, a head portrait is dug out of the snapshot photo; step 5, the processed video information and the head portrait in the snapshot high definition photo are saved. By means of the personnel gathering and snapshooting system, facial features of personnel can be identified intelligently, an alarm is given to unsafe personnel, information of the unsafe personnel is stored, and therefore the unsafe personnel can be effectively prevented and can be tracked in a later period. The personnel gathering and snapshooting system has practicability.
Description
Technical field
The invention relates to sacurity alarm system, points out that a kind of personnel collect capturing system.
Background technology
Traditional personnel collect system and are mostly single video image collection, can not in system, identify personnel's face feature, can not extract head part's feature photo of enough pixels.
Innovation and creation content
For the problems referred to above, the invention proposition personnel collect capturing system.
In order to solve the problems of the technologies described above, the invention is achieved through the following technical solutions:
Personnel collect the control method of capturing system, and described method comprises the following steps:
(1) video acquisition, carries out video information collection by common camera head;
(2) video acquisition is processed, and after the analog video signal of common camera head output is sampled, converts digital signal to;
(3) video identification, analyzes the digital signal after above-mentioned conversion, sends candid photograph signal after meeting candid photograph condition;
(4) capture and control, after candid photograph signal sends, by high definition photographic means, capture and generate photo;
(5) photo reads with high definition photo and generates, and above-mentioned photo is carried out to head part location, and pluck out face's scope pixel of photo, forms head portrait photo.
Further, described video identification also comprises that behavior whether blocked in judgement discovery face, has the alarm signal that provides of the behavior of blocking.
Further, also comprise system light filling, for common camera head gathers video image information and high definition photographic means, capture suitable brightness is provided.
Further, also comprise system storage step, described system storage comprises the video image information of collection is carried out to code storage, forms video data stream and video record file and the head portrait photo plucking out is stored.
Compared with prior art, the beneficial effect of the invention is: the personnel that the invention proposes collect capturing system energy Intelligent Recognition personnel face feature, and unsafe personnel are carried out to alarm and information storage, effectively prevents dangerous personnel, and can follow the trail of in the later stage, there is practicality.
Accompanying drawing explanation
Fig. 1 is the structure chart of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention is described in further detail: personnel collect the control method of capturing system, described method comprises the following steps:
(1) video acquisition, carries out video information collection by common camera head;
(2) video acquisition is processed, and after the analog video signal of common camera head output is sampled, converts digital signal to;
(3) video identification, analyzes the digital signal after above-mentioned conversion, sends candid photograph signal after meeting candid photograph condition;
(4) capture and control, after candid photograph signal sends, by high definition photographic means, capture and generate photo;
(5) photo reads with high definition photo and generates, and above-mentioned photo is carried out to head part location, and pluck out face's scope pixel of photo, forms head portrait photo.
Described video identification also comprises behavior whether blocked in judgement discovery face, the alarm signal that provides that has the behavior of blocking, also comprise system light filling, for common camera head gathers video image information and high definition photographic means, capture suitable brightness is provided, also comprise system storage step, described system storage comprises the video image information of collection is carried out to code storage, forms video data stream and video record file and the head portrait photo plucking out is stored.
In conjunction with Fig. 1, personnel collect each functional module of capturing system, comprise video image collecting unit, video image processing unit, capture unit, alarm unit and transmission control and management unit, described video image processing unit comprises that video acquisition is processed, video coding and storage is managed, video identification, and described candid photograph unit comprises that candid photograph control, high-definition digital camera, photo read control and high definition head portrait generates;
The output of described image collection unit connects the input that video acquisition is processed, the input that the candid photograph of described candid photograph unit is controlled connects the output of video identification, output connects the input of alarm unit, and the output that described video coding and storage management is produced with high definition head portrait is connected the input of transfer control administrative unit.
