Description
Technical field
The present invention relates to the fusion problem for perceiving source information in video monitoring system more, and in particular to Big Dipper receiver number
According to, the acquisition of the multi-source information such as Temperature Humidity Sensor data and video flowing, merge, storage, querying method, belong to security protection video prison
Control field.
Background technology
In the industrial production, each key area has all deployed video monitoring system, can obtain the video in scene
And image, improve the security and manageability of production scene.Generally, there be various environmental key-elements production scene, including when
Between, geography, noise, humiture, wind direction, come in and go out personnel identity information etc., these information can be obtained by various sensing equipments,
It is the information required for safety in production, security protection.But these systems are all the autonomous systems established one's own system, data source is all only
It is vertical to be stored in respective server, it is difficult to comprehensively utilize, carry out the feature of event that accurate description occurred and scene, it is difficult to support
Intelligentized production, scheduling, control, protection, this scattered, independent monitoring system and database are unfavorable for efficient, intelligent work
The needs of industry production management.
In order to improve video monitoring and safety in production, the efficiency of safety precaution and intelligence degree, it is necessary to will be above-mentioned more
Kind environmental information collects fusion, real-time acquisition, storage, the retrieval of systematization by the intelligent video monitoring system of integration
Data, the relevance established between data source, particularly ensure time, the accuracy in place, ensure global coherency, complete
Property, beneficial to alarm of pinpointing the problems, while situation can be analyzed, further do data mining, therefrom excavate valuable
Information, for improving the reaction speed and efficiency of production efficiency, safety precaution, and emergency processing.
The source information integration technologies that perceive come across in the 1970s, how that the data message of separate sources is whole studying more
It is combined, to obtain the result more accurate, more reliable than with single data.It is perceive level of the source information fusion by fusion more
It is divided into 3 kinds of pixel-based fusion, feature-based fusion and decision level fusion.Pixel-based fusion is the fusion of lowest level, directly to passing
The observation data of sensor carry out fusion treatment, are then based on fusion results and carry out feature extraction and judge decision-making.Feature-based fusion
Refer in the raw information that each sensor provides, extract one group of characteristic information first, form characteristic vector, and enter to target
Row classification or other before processings merge to each group information, sometimes referred to as middle rank fusion.Conventional method has clustering methodology,
Artificial neural network and K rank nearest neighbor methods etc..Decision level fusion is high-level fusion, is first based on itself institute by each sensor
The data of collection make decisions, and then complete the fusion treatment to local decision in fusion center.Common algorithms have Bayes to push away
Disconnected, expert system, D-S evidential reasonings etc..
The video frequency monitoring method of existing multisource data fusion is for particular source either in video encoder apparatus
Inside receive multi-source data.A kind of for example, video monitoring pedestrian identification side for multi-source big data fusion that Wuhan University proposes
Method (CN105357496A), the physical identity of pedestrian is identified by the push-to-talk handset number of control point.Observe on travel path
The number of recurrences of phone number on control point where specific suspicion pedestrian, calculates pedestrian, and phone number reappears probability, and two
The combined probability of person identifies the physical identity of pedestrian.Solve and only rely only on monitor video itself to identify monitoring objective identity
Problem of Failure in some cases.Zhongxing Microelectronci Co., Ltd., Beijing proposes a kind of video for supporting multisource data fusion
Method for hierarchically coding (CN106303538A), video is optimized and encode simultaneously together with the multi-source information of external sensor
Step combines, and source video is formed the classification code stream comprising video content and each object video relevant information.Solves existing video
Encoder apparatus can not receive external sensor information and operating efficiency is low, it is impossible to effectively give top priority to what is the most important information the problems such as.
The former invents and achievement is mainly for video monitoring pedestrian's identification of multisource data fusion, and main target is profit
With the number of recurrences of video monitoring and the push-to-talk handset number of control point to identifying rows people's identity.The latter invents and the main pin of achievement
Video spatial scalable coding method to supporting multisource data fusion, main target are that solve existing video encoder not possess outside reception
The problem of portion's Multiple Source Sensor informational function.
