Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Fig. 1 shows a flow chart of a preferred embodiment of the gateway data processing method of the present invention.
The method for processing gateway data is applied to one or more electronic devices, where the electronic devices are devices capable of automatically performing numerical calculation and/or information processing according to preset or stored instructions, and hardware thereof includes, but is not limited to, a microprocessor, an Application Specific Integrated Circuit (ASIC), a Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.
The electronic device may also include a network device and/or a user device. Wherein the network device includes, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a Cloud Computing (Cloud Computing) based Cloud consisting of a large number of hosts or network servers.
The Network where the electronic device is located includes, but is not limited to, the internet, a wide area Network, a metropolitan area Network, a local area Network, a Virtual Private Network (VPN), and the like.
The processing method of gateway data according to the present invention will be described in detail with reference to fig. 1.
A method for processing gateway data may include the following steps.
First, step S10 is executed to pre-configure a plurality of levels of gateway layers, and each level of gateway layer includes a plurality of gateways.
In one embodiment, the multiple levels of gateway layers may include two sets, which are a higher level gateway layer and a lower level gateway layer. The number of gateway layers can allow splitting according to an actual gateway configuration process, and the gateway layers of different levels use administrators of different levels. By arranging a plurality of gateway layers, the splitting of the administrator of the gateway is further realized, so that the efficiency of the gateway in the actual use process is improved.
In particular, when the gateway layer includes a high-level gateway layer and a low-level gateway layer, the high-level gateway layer has a higher authority than the low-level gateway layer. Meanwhile, the gateway located in the high-level gateway layer may allow a plurality of gateways located in the low-level gateway layer to be correspondingly connected. Therefore, the gateway layer at the lowest layer can transfer data to the gateway in the upper layer according to the requirement after acquiring the request instruction and processing the related instruction.
Next, step S20 is executed, where the gateway in the gateway layer at the lowest level is connected to a client and a management device, and the client obtains initial video data and the management device obtains target sample characteristics.
Specifically, a management device and a client are connected to the gateway in the gateway layer of the lowest hierarchy. The gateway may allow for the acquisition of initial video data by the client and target sample characteristics by the management device. It should be noted that the management device includes a storage unit for storing the target sample characteristics, and the management device can update the stored target sample characteristics in real time. Therefore, the management equipment can effectively ensure the accuracy of the characteristics of the target sample acquired by the gateway connected with the management equipment.
It should be noted that the target sample characteristics may allow for determination based on actual requirements. For example, in a public security monitoring system, the target sample features may be three-dimensional features of a human face and human body shape features. Wherein, the gateway of the lowest level gateway layer can be allowed to be connected with a plurality of management devices. Meanwhile, when the gateway is connected with a plurality of management devices, the plurality of management devices are deployed in a distributed manner. By distributed deployment, the execution time of a single task can be shortened to improve efficiency.
Meanwhile, the client comprises an image acquisition device, and the image acquisition device is used for acquiring video and image data. In particular, the image acquisition device may be allowed to include a camera, a face recognition machine, or a snapshot device. The image acquisition device is applied to a specific application scene. For example, the image capturing device is applied as a camera in a skynet in a public security system, but is not limited thereto, and may be determined according to actual needs.
Then, step S30 is executed to extract the initial video data according to the target sample feature, and obtain a video clip including the target feature.
In step S30, the initial video data may be subjected to extraction processing according to the target sample characteristics. The initial video data is processed in the gateway at the bottommost layer in advance, so that the transmission pressure of the gateway in the data transmission process is reduced.
Referring to fig. 2, in an embodiment, the step of extracting the initial video data according to the target sample feature and obtaining the video segment including the target feature may include the following steps.
And S310, copying the initial video data to obtain two video files with the same content.
It will be appreciated that the initial video data is typically high definition video data. The higher definition of the video frame results in higher image quality and pixel height of the video frame, and occupies larger storage space. When the initial video data is directly transmitted, the transmission pressure born by the gateway is large, and the transmission speed of the gateway is influenced. Thus, it is possible to allow subsequent processing steps to be performed after copying the original video data into two identical video files.
S320, performing framing processing on a video file to obtain a first picture set, wherein pictures in the first picture set are continuous high-definition pictures.
Wherein, since the copying of the initial video data has been completed in step S310, it is permissible to select one video file for the framing processing. It should be noted that after the image is subjected to framing processing, the pictures of each frame are respectively associated with time scales on the time axis and sequence number data in the picture set. And acquiring the picture at the corresponding moment according to the corresponding time scale, or acquiring the corresponding picture according to the corresponding serial number data. Therefore, it is allowable that the first picture set including all the continuous pictures is obtained according to the time sequence on the time axis, and the pictures in the first picture set are high definition pictures.
S330, compressing the other video file to obtain a low-definition compressed video, and performing framing processing on the compressed video to obtain a second picture set, wherein pictures in the second picture set are continuous low-definition pictures.
Specifically, by performing compression processing on another video data, the specification of the video data can be reduced. It should be noted that video bitrate is one of the characteristics of video, and thus can allow high definition video to be converted into low definition video by reducing the video bitrate. In the process of video conversion, a code rate threshold value can be preset, so that the converted video is within the same specification. Meanwhile, after the video is compressed, the resolution of the video needs to be adjusted to reduce the definition of the original video.
It can be understood that after the compressed video is obtained, the compressed video is subjected to framing processing to obtain a second picture set, and pictures in the second picture set are continuous low-definition pictures. When performing framing processing on the compressed video, the framing method is the same as the framing method in step S310, and is not described herein again.
S340, comparing and identifying the low-definition picture with the target characteristics, and marking the picture which is successfully identified.
After the second image set is obtained, comparing the images in the second image set frame by frame according to the preset target sample characteristics. And when the pictures in the second picture set are matched with the preset target sample successfully, marking the pictures which are successfully identified. Specifically, for pictures that are successfully identified, the marked content includes specific time data of the pictures on the time axis, and specific serial numbers of the pictures in the second picture set.
And S350, extracting the data information of the successfully identified pictures, and extracting corresponding high-definition pictures from the first picture set according to the data information.
Specifically, the time axis information is extracted based on the pictures in the second picture set that are successfully compared with the preset target sample. And simultaneously, extracting high-definition pictures at corresponding moments in the first picture set through the mapping relation between the first picture set and the second picture set and based on the time axis information. Allowing presetting and establishing a mapping relation between the first picture set and the second picture set, wherein the mapping relation comprises T i =(T 0 *K i )/K 0 (ii) a Wherein, T i Characterizing high definition pictures, T, of a first set of pictures to be extracted 0 Characterizing the number of all pictures in the first picture set, K i Characterizing successfully identified low-resolution pictures in the second picture set, and K 0 And representing the number of all pictures in the second picture set.
S360, combining the high-definition pictures, and acquiring a video clip comprising the target characteristics.
And finally, executing the step S40, encrypting and packaging the video clips including the target characteristics, and transmitting the packaged data packets to corresponding gateways in the upper-level gateway layer.
Wherein, a first tag key corresponding to the video segment of the target feature can be allowed to be determined, and each tag key has a unique corresponding key tag. And encrypting the video clip of the target characteristic through the first label key, packaging a first key label corresponding to the first label key, and transmitting the first key label to a corresponding gateway in a gateway layer of the upper hierarchy.
In particular, a video segment of the target feature may be allowed to be encrypted by a tag key TK, and the tag key TK needs to be encrypted using a Master PK for D0 to be stored. Wherein, TK (Tag-Key): is the Tag key assigned to the Tag, which is a symmetric encryption key. Master PK/SK: the system is a Master key pair, the Master PK is a system public key, the Master SK is a system private key, and the Master SK is generally an RSA public and private key pair distributed to a super administrator. Master-PK is mainly used for encrypting and storing TK, and the Master-SK is a key for opening all label keys in the system; master SK also uses Password encrypted storage. D0: TK is encrypted using Master-PK to give D0. Therefore, by encrypting the data, the security of the data in the transmission process can be effectively improved.
It should be noted that, the steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, and as long as the steps contain the same logical relationship, the steps are within the scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

Specifically, the multiple levels of gateway layers may include two sets, which are the upper level gateway layer 110 and the lower level gateway layer 120, respectively. The number of gateway layers can allow splitting according to an actual gateway configuration flow, and the gateway layers of different levels use different levels of administrators. By arranging a plurality of gateway layers, the splitting of the administrator of the gateway can be realized, so that the efficiency of the gateway in the actual use process is improved.
