Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an alarm video processing method according to an embodiment of the present invention, where the embodiment is applicable to monitoring an alarm site, and the method may be executed by an alarm video processing apparatus, where the apparatus may be implemented in a software and/or hardware manner, and the apparatus may be configured in a terminal device. The method specifically comprises the following steps:
and S110, when the alarm signal is received, determining a monitoring time period corresponding to the alarm signal according to the alarm information of the alarm signal.
The alarm device generates an alarm signal by collecting physical phenomena in a defense deployment monitoring area. In one embodiment, the alarm information optionally includes at least one of an alarm type, an alarm time, an alarm level, an alarm area, and an alarm device number. As an example, the alarm type of the alarm signal may be a fire alarm signal, a temperature alarm signal, a special gas alarm signal, an illegal intrusion alarm signal, and the like. The alarm time includes the time when the alarm device has collected the target physical phenomenon, for example, the target physical phenomenon may be a temperature higher than 50 ℃, and the alarm time may be 12 months, 1 day, 13: 00. The alarm level is the danger level of the alarm signal of the different alarm types set by the user. Illustratively, the alarm level of the fire alarm signal is a first alarm level, and the alarm level of the illegal intrusion alarm signal is a second alarm level, wherein the first level is higher than the second level. Different alarm devices may correspond to the same or different monitoring areas, for example, when the alarm device 1 sends out an alarm signal, the monitoring area corresponding to the alarm device 1 is used as an alarm area, and the alarm area and the number 1 are used as alarm information.
In one embodiment, optionally, the monitoring duration range is determined according to at least one of the alarm type, the alarm time and the alarm level of the alarm signal, and the monitoring period corresponding to the alarm signal is determined according to the alarm time and the monitoring duration range.
In one embodiment, optionally, the monitoring duration range includes a duration range before the alarm time and/or a duration range after the alarm time. The time length range before the alarm time and the time length range after the alarm time can be the same or different. For example, when the monitoring time length range includes a time length range before the alarm time and a time length range after the alarm time, assuming that the monitoring time length range is 10 minutes, the time length ranges before the alarm time and after the alarm time may be both 5 minutes. Of course, the time period before the alarm time may be in the range of 6 minutes, and the time period after the alarm time may be in the range of 4 minutes.
In one embodiment, optionally, a mapping relationship between the alarm information and the monitoring duration range is established, and the monitoring duration range corresponding to the alarm signal is determined according to the mapping relationship. In one embodiment, when only one type of the alarm information is available, if the alarm information is of an alarm level, the monitoring duration range corresponding to the first alarm level is 10 minutes, and the monitoring duration range corresponding to the second alarm level is 5 minutes. In another embodiment, when the alarm information comprises at least two types, such as an alarm level and an alarm time, the alarm time is between 7:00 and 18:00, and the alarm level is a first alarm level, the monitoring time duration range is 10 minutes; when the alarm time is between 20:00 and 24:00 and the alarm level is the second alarm level, although the alarm level of the alarm signal is the second alarm level, the alarm signal occurs at night, and personnel cannot process the alarm event in time, so the monitoring time length range can be set to be 20 minutes. The mapping relation between the alarm information and the monitoring time range is not limited, and the mapping relation can be set reasonably according to actual conditions.
In one embodiment, optionally, the monitoring duration range corresponding to each monitoring device is determined according to the distance between the alarm device corresponding to the alarm signal and the at least one monitoring device corresponding to the alarm signal. The monitoring device corresponding to the alarm signal exemplarily includes a monitoring device a and a monitoring device B, a distance between the monitoring device a and the alarm device is 10m, and a distance between the monitoring device B and the alarm device is 5m, so that a monitoring duration range corresponding to the monitoring device B is greater than a monitoring duration range corresponding to the monitoring device a.
Wherein, for example, assuming that the alarm time is 13:00, and the monitoring duration range includes 10 minutes before the alarm time and 20 minutes after the alarm time, the monitoring period is 12:50-13: 20.
And S120, acquiring video data in the monitoring time period in the monitoring equipment corresponding to the alarm signal, and generating an alarm video.
The monitoring equipment is used for recording real-time or timing video of scene information of a defense deployment monitoring area. In one embodiment, optionally, the number of monitoring devices corresponding to the alarm signal is at least one. Specifically, an association relationship is established between the alarm device and the monitoring device, for example, the alarm device 1 corresponds to the monitoring device a and the monitoring device B. When the alarm device 1 sends out an alarm signal, the monitoring devices corresponding to the alarm signal include a monitoring device a and a monitoring device B.
When the monitoring device records the video data at regular time, after receiving the alarm signal, in one embodiment, if the monitoring device is in a closed state, the monitoring device is controlled to start a video recording function so as to acquire the video data of a monitoring time period corresponding to the alarm signal. Illustratively, when the alarm time is 13:00 and the monitoring time period is 13:00-13:10, the monitoring device is controlled to record 10 minutes of video data. In another embodiment, if the monitoring device is in an on state and the time difference between the alarm time and the timing off time of the monitoring device is smaller than the monitoring duration range after the alarm time, the timing off time is adjusted according to the monitoring duration range. Illustratively, when the alarm time is 13:00, the monitoring time period is 13:00-13:10, and the timing off time of the monitoring device is 13:05, the timing off time of the monitoring device is adjusted to 13: 10.
The alarm video comprises video data in a monitoring time period corresponding to each monitoring device. Illustratively, the alarm video includes video data from 13:00 to 13:10 in monitoring device A and video data from 13:00 to 13:10 in monitoring device B. In one embodiment, the alarm video corresponding to each monitoring device is displayed in different windows of the display device. In another embodiment, a monitoring device selected by a user is received, and an alarm video corresponding to the monitoring device is displayed in a window of a display device.
The format of the alarm video stored in the existing video monitoring scheme is generally an H264 video format, and in this embodiment, optionally, after the alarm video is generated, the alarm video is stored in an MP4 video format.
On the basis of the above embodiment, optionally, audio data in a monitoring time period in the monitoring device corresponding to the alarm signal is acquired, and an alarm audio is generated. The advantage that sets up like this lies in, audio data is faster for video data's acquisition speed, and when the user was inconvenient to look over the warning video, the condition in the monitoring area was known fast to the accessible warning audio frequency to improve the treatment effeciency of the warning condition.
On the basis of the foregoing embodiment, optionally, the method further includes: when a plurality of alarm signals are received within a preset time interval, if a plurality of generated alarm videos correspond to the same monitoring equipment, the plurality of alarm videos are subjected to duplicate removal processing.
The preset time interval may be, for example, 1 second, 5 seconds, or 10 seconds. Of course, the preset time interval may also be 0. When the preset time interval is 0, namely, the alarm devices send out alarm signals at the same time. Wherein, the alarm information of each alarm signal can be the same or different.
Wherein, the same alarm signal corresponds to at least one monitoring device, and different alarm signals may correspond to the same monitoring device. Illustratively, alarm signal 1 corresponds to monitoring device a, monitoring device B, and monitoring device C, and alarm signal 2 corresponds to monitoring device a, monitoring device D, and monitoring device E. In one embodiment, when alarm signal 1 and alarm signal 2 are received within a preset time interval, the alarm video a1 and the alarm video a2 generated according to alarm signal 1 and alarm signal 2, respectively, correspond to the monitoring device a. Because the alarm time of the alarm signal 1 is similar to or the same as that of the alarm signal 2, the video contents of the alarm video a1 and the alarm video a2 are also similar to or the same as each other, and two identical or similar sets of video data occupy more server resources, which causes waste of server resources.
In one embodiment, the deduplication processing method optionally includes a key frame matching method and a visual feature extraction method. In the exemplary method, the key frame image of the alarm video is selected, the key frame image is matched with the key frame image of another alarm video, and if the matching is successful, the two alarm videos are regarded as the repeated alarm videos. The visual feature extraction method is characterized in that video frame images in the alarm videos are counted based on colors and/or textures to obtain color histograms and/or texture histograms, and the similarity of the color histograms and/or the texture histograms of the two alarm videos is compared. And if the similarity meets a preset similarity threshold, the two alarm videos are regarded as repeated alarm videos.
In one embodiment, optionally, the deduplication processing is performed on a plurality of alarm videos, including: taking one of the plurality of alarm videos as a target alarm video, and taking at least one alarm video except the target alarm video as a reference alarm video; determining a deduplication time period according to the start time, the end time and the floating time of the monitoring time period corresponding to the target alarm video, respectively matching the monitoring time period of each reference alarm video with the deduplication time period, and deleting the reference alarm video corresponding to the successfully matched monitoring time period.
The floating time may be 1 second, 30 seconds or 1 minute, for example, but the floating time may also be 0. Wherein, when the floating time is not 0, the floating time can be used to remove the influence of the preset time interval on the deduplication processing. Illustratively, when the preset time interval is 5 minutes, the monitoring time period corresponding to the alarm video A is set to be 13:10-13:30, and the monitoring time period corresponding to the alarm video B is set to be 13:05-13: 25. If the floating time is 0, both the alarm video a and the alarm video B are retained after the deduplication processing. If the float time is not 0, in an embodiment, optionally, the float time is greater than or equal to a preset time interval. Where, illustratively, the float time is 6 minutes. And taking the alarm video A as a target alarm video, determining the de-duplication time period to be (13: 04-13: 16) - (13:24-13:36), matching the alarm video B with the de-duplication time period, and only keeping the alarm video A after de-duplication processing.
The method has the advantages that resource waste rate of the server can be reduced, and operation efficiency of the server is guaranteed. In practical application, if the alarm video 1 corresponding to the alarm signal 1 is deleted due to the repetition with the alarm video 2, the server may call the saved alarm video 2 to display to the user when the user views the alarm video 1 corresponding to the alarm signal 1.
According to the technical scheme of the embodiment, the monitoring time period is determined according to the alarm information of the alarm signal, and the video in the monitoring time period in the monitoring equipment is used as the alarm video, so that the problem of redundant alarm video data is solved, the waste of server resources is avoided, the pertinence of the alarm video is improved, and the subsequent processing efficiency of the alarm video data and the alarm condition is improved.
Example two
Fig. 2 is a flowchart of a method for processing an alarm video according to a second embodiment of the present invention, and the technical solution of the present embodiment is further detailed based on the above-mentioned embodiments. Optionally, the obtaining video data in the monitoring period of the monitoring device corresponding to the alarm signal and generating an alarm video includes: when a plurality of alarm signals are received within a preset time interval, sequencing the alarm signals according to the alarm information of the alarm signals, and sequencing the monitoring equipment corresponding to the alarm signals according to the sequencing result to obtain a monitoring execution queue; and sequentially acquiring video data in the monitoring time period corresponding to each alarm signal in each monitoring device according to the monitoring execution queue, and generating an alarm video corresponding to each alarm signal.
The specific implementation steps of this embodiment include:
s210, when a plurality of alarm signals are received within a preset time interval, determining a monitoring time period corresponding to the alarm signals according to alarm information of the alarm signals.
S220, sequencing the alarm signals according to the alarm information of the alarm signals, and sequencing the monitoring devices corresponding to the alarm signals according to the sequencing result to obtain a monitoring execution queue.
In one embodiment, the alert information optionally includes at least one of an alert type, an alert time, and an alert level. In one embodiment, the alarm information is an alarm level, and the alarm signals are sorted according to the level of the alarm level of each alarm signal. Illustratively, the alarm level corresponding to the alarm signal 1 is a first alarm level, the alarm level corresponding to the alarm signal 2 is a second alarm level, and the level of the first alarm level is higher than that of the second alarm level, the sequencing result is the alarm signal 1 and the alarm signal 2. When the same alarm level corresponds to a plurality of alarm signals, the alarm signals can be randomly sequenced. In another embodiment, the alarm information includes alarm time and alarm level, and the alarm signals are sorted according to the level of the alarm signal, and at least two alarm signals corresponding to the alarm levels are sorted according to the alarm time. Illustratively, the first alarm level corresponds to alarm signal 1 and alarm signal 2, the second alarm level corresponds to alarm signal 3 and alarm signal 4, the alarm signals 1 and 2 are sorted according to the alarm time, and the alarm signals 3 and 4 are sorted according to the alarm time. The ranking of alarm signal 1 is higher than alarm signal 2, assuming that the alarm time of alarm signal 1 is before the alarm time of alarm signal 2.
Wherein each alarm signal corresponds to at least one monitoring device. For example, alarm signal 1 corresponds to monitoring device a and monitoring device B, and alarm signal 2 corresponds to monitoring device C and monitoring device D, so the monitoring execution queue may be monitoring device a, monitoring device B, monitoring device C, and monitoring device D. At least one monitoring device corresponding to the alarm signal can be randomly sequenced, or sequenced according to the distance between each monitoring device and the alarm device.
In one embodiment, there is an overlap between the monitoring devices for multiple alarm signals. Illustratively, the alarm signal 1 corresponds to the monitoring device a and the monitoring device B, the alarm signal 2 corresponds to the monitoring device a and the monitoring device D, and if the monitoring devices are directly sorted according to the sorting result of the alarm signal, the monitoring execution queues are the monitoring device a, the monitoring device B, the monitoring device a and the monitoring device D. The monitoring device a appears twice, and if the alarm video is acquired according to the monitoring execution queue, the alarm video with similar content or similar time appears, so that the load of the server is increased. In an embodiment, optionally, the sorting the monitoring devices corresponding to the alarm signals according to the sorting result to obtain a monitoring execution queue includes: and according to each alarm signal in the sequencing result, if the current monitoring equipment corresponding to the alarm signal does not exist in the current monitoring execution queue, adding the current monitoring equipment to the current monitoring execution queue to obtain a monitoring execution queue.
In an exemplary case, it is assumed that the ranking level of the alarm signal 1 is higher than that of the alarm signal 2, the alarm signal 1 corresponds to the monitoring device a and the monitoring device B, and the alarm signal 2 corresponds to the monitoring device a and the monitoring device D. When the monitoring devices corresponding to the alarm signal 1 are sequenced, a current monitoring execution queue is obtained: monitoring device a and monitoring device B. When the monitoring equipment corresponding to the alarm signal 2 is sequenced, because the monitoring equipment A is already in the current monitoring execution queue, the monitoring equipment A corresponding to the alarm signal 2 is not sequenced; because the monitoring device D does not exist in the current monitoring execution queue, the monitoring device D corresponding to the alarm signal 2 is added to the current monitoring execution queue to obtain a monitoring execution queue: monitoring equipment A, monitoring equipment B and monitoring equipment D.
And S230, sequentially acquiring video data in the monitoring time period corresponding to each alarm signal in each monitoring device according to the monitoring execution queue, and generating an alarm video corresponding to each alarm signal.
Wherein, the monitoring equipment corresponding to a plurality of alarm signals has the condition of overlapping. In one embodiment, when determining the monitoring execution queue, if the overlapping of the monitoring devices is not considered, the monitoring execution queue is exemplarily a monitoring device a, a monitoring device B, a monitoring device a, and a monitoring device D. In an embodiment, optionally, sequentially obtaining video data in the monitoring time period corresponding to each alarm signal in each monitoring device according to the monitoring execution queue includes: and if the current monitoring equipment corresponding to the current alarm signal is the same as the monitoring equipment corresponding to the acquired video data, taking the video data corresponding to the acquired current monitoring equipment as the video data of the current alarm signal.
Specifically, it is assumed that monitoring device a and monitoring device B correspond to alarm signal 1, and monitoring device a and monitoring device D correspond to alarm signal 2. And sequentially acquiring the video data A of the first monitoring equipment A and the video data B of the monitoring equipment B according to the monitoring execution queue to obtain 2 alarm videos corresponding to the alarm signal 1. When the video data of the second monitoring device a in the monitoring execution queue is obtained, the second monitoring device a is the same as the monitoring device corresponding to the video data a, the video data a is used as the video data corresponding to the alarm signal 2, and since the monitoring devices D are different from the monitoring devices corresponding to the video data a and the video data B, the video data D in the monitoring device D can be obtained, and 2 alarm videos corresponding to the alarm signal 2 are obtained.
On the basis of the above embodiment, optionally, at least two video monitoring schemes are integrated, and the video monitoring scheme corresponding to the scheme selection operation is run according to the scheme selection operation input by the user. Illustratively, each video monitoring scheme defines at least one of a mode of an alarm level of an alarm signal, a mapping relation between a monitoring duration range and alarm information, and a generation mode of a monitoring execution queue. When the video scheme is selected, information such as an internet interconnection protocol, a computer port and an account password can be configured, so that the selected video scheme can be configured in the current video monitoring platform. The advantage that sets up like this lies in, and the user can be according to the control demand of reality, and the process of adjusting to the parameter in the control scheme has been avoided manually repeatedly to the nimble video monitoring scheme that selects that corresponds, has simplified video monitoring's step, and has reduced parameter adjustment and has appeared wrong wind direction, and then improves video monitoring's efficiency.
On the basis of the above embodiment, optionally, after the alarm video is generated, the alarm video is sent to the terminal device corresponding to the alarm signal. Illustratively, when the alarm signal is a fire alarm signal, sending an alarm video to a terminal device of a fire department; and when the alarm signal is an illegal intrusion signal, sending the alarm video to the terminal equipment of the security part. The terminal device may be any one of a desktop computer, a notebook computer, a smart phone, a tablet computer, and a device capable of playing a video file, and the type of the terminal device is not limited herein.
According to the technical scheme, the video data in the monitoring equipment are sequentially acquired through the monitoring execution queue, the alarm video is generated, the problem that the processing efficiency of the server is low when multiple alarm signals are sent concurrently is solved, the processing pressure of the server when the multiple alarm signals are sent concurrently is reduced, the probability of the occurrence of the fault problem caused by network occupation is further reduced, and the generation efficiency of the alarm video is improved.
