Detailed Description
The manner in which the invention can be practiced is illustrated in the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated descriptions of this portion are appropriately simplified or omitted.
Embodiment 1
Fig. 1 is a block diagram of a monitoring camera system to which the video information storage device according to embodiment 1 of the present invention is applied.
In fig. 1, a surveillance camera 1 photographs the inside of a surveillance area. For example, the monitoring camera 1 photographs the inside of a building. The monitoring camera 1 has a video information output unit 1a. The video information output unit 1a outputs video information of the monitoring camera 1. A plurality of monitoring cameras 1 are sometimes provided in a monitoring area.
For example, the personal computer 2 is provided in a management room of a monitoring area. The personal computer 2 has a selection unit 2a. The selecting unit 2a changes the setting of the monitoring camera system according to an operation from the outside.
The video information storage device 3 includes a video information main body storage unit 3a, a video information input unit 3b, a video information temporary storage unit 3c, a video information similarity determination unit 3d, a video information deletion unit 3e, and a video information index unit 3f.
The video information main body storage unit 3a stores video information of the monitoring camera 1.
The image information input unit 3b receives an input of image information from the monitoring camera 1.
The video information temporary storage unit 3c temporarily stores the video information input to the video information input unit 3 b.
The video information similarity determination unit 3d determines the similarity between the video information temporarily stored in the video information temporary storage unit 3c and all the previous video information stored in the video information main body storage unit 3a. For example, the video information similarity determination unit 3d determines the similarity by a known moving body detection method.
The video information similarity determination unit 3d causes the video information main body storage unit 3a to store the video information when the similarity value is not greater than a predetermined value in all the past video information. The video information similarity determination unit 3d does not cause the video information main body storage unit 3a to store the video information when the value of the similarity in any past video information is larger than a predetermined value.
The video information deletion unit 3e deletes the video information for which the determination by the video information similarity determination unit 3d has been completed, from the video information temporary storage unit 3 c. For example, when the similarity value is not greater than a predetermined value in all the past video information, the video information deleting unit 3e stores the video information in the video information main body storage unit 3a and then deletes the video information from the video information temporary storage unit 3 c. For example, when the similarity value in any past video information is larger than a predetermined value, the video information deleting unit 3e deletes the video information from the video information temporary storage unit 3c even if the video information is not stored in the video information main body storage unit 3 a.
The video information index unit 3f stores table information on the video information. For example, when the similarity value is larger than a predetermined value, the video information index unit 3f stores information indicating past video information for which the similarity value with the video information is determined to be larger than the predetermined value in the table information, as a reference object for the video information.
In addition, when the reference image information of the image information deleted because the similarity value is larger than the preset value is deleted, the image information main body storage unit 3a stores the reference image information of the image information as the image information.
Next, the condition for determining the similarity will be described with reference to fig. 2.
Fig. 2 is a diagram for explaining conditions under which the similarity is determined by the video information storage device according to embodiment 1 of the present invention.
The video information similarity determination unit 3d changes the range of video information when determining the similarity between the video information temporarily stored in the video information temporary storage unit 3c and the past video information stored in the video information main body storage unit 3a, in response to an instruction from the outside. Specifically, the video information similarity determination unit 3d changes the range of the video information at the time of determining the similarity in response to an instruction from the selection unit 2a of the personal computer 2.
For example, for "1 st monitoring camera", image information "whole" is set as the determination area. All the past periods are set as the determination period. 99% was set as the threshold for similarity.
For example, for "the 2 nd monitoring camera", a "part" of the video information is set as the determination area. The last 2 hours are set as the determination period. 95% is set as the threshold of similarity. For "2 nd monitoring camera", a determination exception area is also set.
For example, the determination exception area is an image area that is not meaningful when the similarity is determined. For example, in a room, walls, hallways, and ceilings are set as determination exception areas. For example, in the outdoors, clouds, buildings, and trees are set as determination exception areas. The image information of the determination exception area is set to be selectable as to whether or not to perform automatic deletion.
Next, table information will be described with reference to fig. 3.
Fig. 3 is a diagram showing table information of the video information storage device according to embodiment 1 of the present invention.
As shown in fig. 3, the table information is information in which information of "monitoring camera", information of "time (frame)", information of "flag", and information of "index" are associated.
The "monitoring camera" indicates a name inherent to the monitoring camera 1. "time (frame)" means a time corresponding to a plurality of frames in the video information. The "flag" indicates special matters for the frame. The "index" indicates details of special matters for the frame.
For example, in "1 st monitoring camera", at "2016:12:12 10:50:30 900 "frame and" 2016:12:12 10:50:30 300", delete" 2016:12:12 10:50:30 900 "frames.
At this time, for and "2016:12:12 10:50:30 900 "corresponding" flag "marks" delete "such information. And "2016:12:12 10:50:30 900 "corresponding" index "label" 2016:12:12 10:50:30 Reference numeral 300 denotes information such as a reference object.
In contrast, the pair and "2016:12:12 10:50:30 300 "corresponding" flag "marks" reference party "information. And "2016:12:12 10:50:30 300 "corresponding" index "label" from 2016:12:12 10:50:30 900 refers to such information.
For example, in "2 nd monitoring camera", at "2016:12:12 10:50:31 200 "frame and" 2016:12:12 10:50:30 600 "in the case of a similar frame, delete" 2016:12:12 10:50:31 200 "frames.
At this time, for and "2016:12:12 10:50:31 200 "corresponding" flag "marks" delete "such information. And "2016:12:12 10:50:31 200 "corresponding" index "label" 2016:12:12 10:50:30 Reference numeral 600 denotes information such as a reference object.
In contrast, the pair and "2016:12:12 10:50:30 600 "corresponding" flag "marks" reference party "information. And "2016:12:12 10:50:30 600 "corresponding" index "label" from 2016:12:12 10:50:31 200 refers to such information.
Next, a method of sorting image information will be described with reference to fig. 4.
Fig. 4 is a diagram showing table information of the video information storage device according to embodiment 1 of the present invention.
For example, the video information main body storage unit 3a may delete the earliest video information In the form of a FIFO (First-In First-Out). In this case, the video information main body storage unit 3a deletes the information corresponding to "2016" in fig. 4: 12:12 10:50:30 000 "corresponding frames.
However, the video information main body storage unit 3a performs deletion and "2016:12:12 10:50:30 Before the image information of the frame corresponding to 000", store and" 2016:12:12 10:50:30 000", as image information of a frame corresponding to" 2016:12:12 10:50:30 900 "image information of the corresponding frame.
At this time, the video information index unit 3f performs the following operations: 12:12 10:50:30 900 "corresponding" flag "marks" resume "such information. Further, the sum "2016:12:12 10:50:30 900 "corresponding" index "label" from 2016:12:12 10:50:30 000 copies "such information.
Next, an outline of the operation of the video information storage device 3 will be described with reference to fig. 5.
Fig. 5 is a flowchart for explaining an outline of the operation of the video information storage device of the elevator in embodiment 1 of the present invention.
In step S1, the video information storage device 3 determines whether or not video information of the monitoring camera 1 is input to the video information input unit 3 b. When the video information of the monitoring camera 1 is not input in step S1, the video information storage device 3 performs the operation of step S1. When the video information of the monitoring camera 1 is input in step S1, the video information storage device 3 performs the operation of step S2.
In step S2, the video information storage device 3 temporarily stores the video information input to the video information input unit 3b in the video information temporary storage unit 3 c. Then, the video information storage device 3 performs the operation of step S3.
In step S3, the video information storage device 3 determines in the video information similarity determination unit 3d whether or not the value of the similarity between the video information temporarily stored in the video information temporary storage unit 3c and the video information stored in the video information main body storage unit 3a is greater than a preset value.
In step S3, when the value of the similarity between the video information temporarily stored in the video information temporary storage unit 3c and the video information stored in the video information main body storage unit 3a is not greater than the preset value, the video information storage device 3 performs the operation of step S4. In step S4, the video information storage device 3 stores the video information temporarily stored in the video information temporary storage unit 3c in the video information main body storage unit 3 a. Then, the video information storage device 3 performs the operation of step S1.
In step S3, when the value of the similarity between the video information temporarily stored in the video information temporary storage unit 3c and the video information stored in the video information main body storage unit 3a is greater than a preset value, the video information storage device 3 performs the operation of step S5. In step S5, the video information storage device 3 deletes the video information temporarily stored in the video information temporary storage unit 3c in the video information deletion unit 3 e. Then, the video information storage device 3 performs the operation of step S1.
According to embodiment 1 described above, when the degree of similarity with the past video information is greater than a predetermined value, the video information is deleted. Therefore, the storage capacity of the video information storage device 3 can be reduced. In addition, if the storage capacity is the same, the recording time of the video information can be prolonged.
In addition, the range of the video information can be changed when the similarity of the video information is determined. Therefore, the criterion for determining the similarity can be appropriately set according to the installation environment of the monitoring camera 1 or the performance of the video information storage device 3.
The video information index unit 3f stores information indicating past video information for which the similarity value with respect to the video information deleted from the video information temporary storage unit 3c is determined to be greater than the predetermined similarity value, as a reference object for the video information deleted from the video information temporary storage unit 3 c. Therefore, when it is desired to confirm the video information at the time corresponding to the video information deleted from the video information temporary storage unit 3c, the reference target video information can be presented instead of the video information.
When the reference image information of the image information deleted from the image information temporary storage unit 3c is deleted, the image information main body storage unit 3a stores the reference image information of the image information deleted from the image information temporary storage unit 3c as the image information deleted from the image information temporary storage unit 3 c. Therefore, even in the case of deleting video information in the FIFO format, necessary video information can be retained.
Next, an example of the video information storage device 3 will be described with reference to fig. 6.
Fig. 6 is a hardware configuration diagram of the video information storage device according to embodiment 1 of the present invention.
Each function of the video information storage device 3 can be realized by a processing circuit. For example, the processing circuit has at least 1 processor 4a and at least 1 memory 4b. For example, the processing circuit has at least 1 dedicated hardware 5.
In the case where the processing circuit has at least 1 processor 4a and at least 1 memory 4b, each function of the video information storage device 3 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is referred to as a program. At least one of the software and firmware is stored in at least 1 memory 4 b. At least 1 processor 4a reads out and executes a program stored in at least 1 memory 4b, thereby realizing the respective functions of the video information storage device 3. At least 1 processor 4a is also called CPU (Central Processing Unit), central processing unit, computing unit, microprocessor, microcomputer, DSP. For example, at least 1 memory 4b is a nonvolatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, etc., a magnetic disk, a floppy disk, an optical disk, a high-density disk, a mini disk, a DVD, etc.
In case the processing circuit has at least 1 dedicated hardware 5, the processing circuit is implemented for example by a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA or a combination thereof. For example, each function of the video information storage device 3 is realized by a processing circuit. For example, the functions of the video information storage device 3 are unified by a processing circuit.
The functions of the video information storage device 3 may be implemented in one part by dedicated hardware 5 and in another part by software or firmware. For example, the function of the video information similarity determination unit 3d may be realized by a processing circuit which is dedicated hardware 5, and the functions other than the function of the video information similarity determination unit 3d may be realized by at least 1 processor 4a reading out and executing a program stored in at least 1 memory 4 b.
In this way, the processing circuit realizes each function of the video information storage device 3 by the hardware 5, software, firmware, or a combination thereof.
