[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Currently, there is a problem of video loss in the recording of existing video recording equipment. The existing method of detecting the lost video time period is only to determine the stop and start time of the video recording by thinking or monitoring the video itself. This method may ignore some subtle video loss situations.

[0042] To this end, the embodiment of the present application proposes a solution for determining the time period of video loss, which can improve the accuracy of detecting video loss.

[0043] The present application embodiment discloses a method for determining a video loss time period. Figure 1 As shown, the method includes:

[0044] Step S11: querying a number of video time stamps of a video recording device in a clear order within a target time range.

[0045] In this embodiment, the video recording timestamp can be accurate to the year and month.

[0046] In this embodiment, after determining the video timestamp, it is possible to first check whether there is a video, and if so, proceed to the subsequent steps.

[0047] Step S12: Determine the time difference between adjacent video time stamps.

[0048] In this embodiment, the adjacent video recording timestamps are two timestamps, the first timestamp and the last timestamp are used to calculate the difference once, and the other timestamps are used to calculate the difference twice.

[0049] Step S13: determining whether there is a breakpoint between the adjacent video time stamps based on the time difference.

[0050] In this embodiment, judging whether there is a breakpoint between the adjacent video time stamps based on the time difference includes: judging whether the time difference is greater than a first preset time period; if it is greater than the first preset time period, determining that there is a breakpoint between the adjacent video time stamps. Specifically, judging the continuity and integrity of the time stamps, if there is a breakpoint, it is discontinuous and incomplete.

[0051] It should be pointed out that if the time difference between adjacent recording timestamps is greater than the first preset time period, there is a breakpoint between the adjacent recording timestamps. If the time difference between adjacent recording timestamps is not greater than the first preset time period, there is no breakpoint between the adjacent recording timestamps. Specifically, breakpoints are generally caused by equipment failure or network reasons. By checking the completeness, the specific time of the breakpoint can be found, and then the cause can be located to improve product reliability. In view of some breakpoints, system logs are also missed. Checking the completeness can assist in discovering the deficiencies of the log system. Some industries, such as the medical field, require that no breakpoints are allowed within the recording time range. By checking the completeness, potential monitoring failures can be discovered in time and potential risks can be resolved in time. Therefore, if a breakpoint problem is found, the cause of the problem can be located to solve the problem, which can improve the stability of the recording equipment.

[0052] Step S14: If there is a breakpoint, traverse the adjacent video timestamps where the breakpoint exists to determine the video loss time period within the target time range.

[0053] In this embodiment, traversing the adjacent video timestamps where the breakpoint exists to determine the video loss time period within the target time range includes: traversing the adjacent video timestamps where the breakpoint exists, and recording the breakpoint start timestamp and the breakpoint end timestamp of each breakpoint; the breakpoint start timestamp of the breakpoint is the end timestamp of the previous video timestamp of the breakpoint; the breakpoint end timestamp of the breakpoint is the start timestamp of the current video timestamp of the breakpoint; converting the breakpoint start timestamp and the breakpoint end timestamp into specific time to determine the video loss time period within the target time range.

[0054] It should be pointed out that the timestamp of the video with the breakpoint is traversed (the length of the timestamp depends on the video to be checked, which can be one day, one week or one month, and the specific time can be customized), and the timestamps before and after each breakpoint are recorded as the start and end of the breakpoint. These timestamps are converted into specific time points and returned. By doing so, all the missing time periods of a certain year and month can be clearly viewed; (A normal complete video record is usually a list containing a set of data, such as the video record of June 4, which is generally [1717430400, 1717516799] without interruption, 1717430400 means 2024-06-04 00:00:00, 1717516799 means 2024-06-04 23:59:59, while the video records with breakpoints are multiple groups of data, such as [1717430400, 1717469999], [1717473599, 1717516799], 1717469999 means 2024-06-04 10:59:59, 1717473599 means 2024-06-04 11:59:59, this record means there is a breakpoint, the breakpoint time is 10:59:59 to 11:59:59, the breakpoint time is 1H, this method starts from the first set of data in the list, compares the last timestamp of the previous set of data with the start timestamp of the next set of data, until the last set of data is traversed, if the difference between the previous and the next exceeds the expected value, it is judged that the recording is incomplete, for example, the breakpoint of the above set of data starts at 10:59:59 and ends at 11:59:59).

[0055] It can be seen that the present application queries several video timestamps of a clear order within the target time range of the video recording device; determines the time difference between adjacent video timestamps; based on the time difference, determines whether there is a breakpoint between the adjacent video timestamps; if there is a breakpoint, traverses the adjacent video timestamps with the breakpoint to determine the video loss time period within the target time range. It can be seen that the present application does not determine the video loss based on the observation of the video, but determines the observation target as the timestamp, determines whether there is a breakpoint between adjacent timestamps, and then traverses the adjacent video timestamps with the breakpoint to determine the video loss time period within the target time range, so that the judgment of video loss is more detailed, does not ignore subtle video loss, and improves the accuracy of detecting video loss.

[0056] The embodiment of the present application discloses a specific method for determining the video loss time period. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. Figure 2 As shown, specifically including:

[0057] Step S21: querying a number of video time stamps of a video recording device in a clear order within a target time range.

[0058] Step S22: Determine the time difference between adjacent video time stamps.

[0059] Step S23: determining whether the time difference between adjacent video time stamps is within a preset error range; if the time difference is within the preset error range, merging the adjacent video time stamps to obtain a plurality of new video time stamps.

[0060] In this embodiment, the preset error range can be set according to the actual situation of the video recording device, so the preset error ranges corresponding to different video recording devices are the same or different.

[0061] In this embodiment, the determining whether the time difference between adjacent video recording timestamps is within a preset error range includes: determining whether the time difference between adjacent video recording timestamps is greater than a second preset time period; if it is not greater than the second preset time period, the time difference between adjacent video recording timestamps is within the preset error range.

[0062] In this embodiment, merging the adjacent video timestamps includes: setting the end time of a previous video timestamp in the adjacent video timestamps as the start time of the next video timestamp.

[0063] It should be pointed out that if the video deviation within the second preset time period is within the allowable error range, you can first traverse the timestamps to check whether the difference exceeds the second preset time period. If it does not exceed the second preset time period, the end time of the previous video timestamp in the adjacent video timestamps is set to the start time of the next video timestamp, and those that exceed the second preset time period will not be processed; (The purpose of combined filtering: during the recording process of the actual monitoring device, if there is network fluctuations that cause packet loss and retransmission, the timestamp of the video index will be cut off. In this case, the video playback view is continuous, but due to insufficient retransmission frame rate, the video index timestamp is disconnected).

[0064] It should be noted that the second preset time period has no correlation with the first preset time period, and both are set according to actual conditions.

[0065] Step S24: determining whether there is a breakpoint between the adjacent video time stamps based on the time difference.

[0066] Step S25: If there is a breakpoint, traverse the adjacent video timestamps where the breakpoint exists to determine the video loss time period within the target time range.

[0067] It can be seen that the present application queries the video recording device for several video recording timestamps with a clear sequence within the target time range; determines the time difference between adjacent video recording timestamps; determines whether the time difference between adjacent video recording timestamps is within the preset error range; if the time difference is within the preset error range, merges the adjacent video recording timestamps to obtain several new video recording timestamps; determines whether there is a breakpoint between the adjacent video recording timestamps based on the time difference; if there is a breakpoint, traverses the adjacent video recording timestamps with the breakpoint to determine the video recording loss time period within the target time range. It can be seen that the present application does not determine the video recording loss based on the observation of the video recording, but determines the observation target as the timestamp, determines whether there is a breakpoint between the adjacent timestamps, and then traverses the adjacent video recording timestamps with the breakpoint to determine the video recording loss time period within the target time range, so that the judgment of video recording loss is more detailed, and subtle video recording loss will not be ignored, thereby improving the accuracy of detecting video recording loss; the present application determines whether it is within the error range, reduces the recording of invalid breakpoints, and improves accuracy.

[0068] Correspondingly, the embodiment of the present application also discloses a device for determining a video loss time period, see Figure 3 As shown, the device comprises:

[0071] A breakpoint determination module 13, configured to determine whether there is a breakpoint between the adjacent video time stamps based on the time difference;

[0072] The traversal module 14 is used to traverse the adjacent video time stamps of the breakpoint if there is a breakpoint, so as to determine the video loss time period within the target time range.

[0073] It can be seen that the present application queries several video timestamps of a clear order within the target time range of the video recording device; determines the time difference between adjacent video timestamps; based on the time difference, determines whether there is a breakpoint between the adjacent video timestamps; if there is a breakpoint, traverses the adjacent video timestamps with the breakpoint to determine the video loss time period within the target time range. It can be seen that the present application does not determine the video loss based on the observation of the video, but determines the observation target as the timestamp, determines whether there is a breakpoint between adjacent timestamps, and then traverses the adjacent video timestamps with the breakpoint to determine the video loss time period within the target time range, so that the judgment of video loss is more detailed, does not ignore subtle video loss, and improves the accuracy of detecting video loss.

[0074] In one embodiment, the breakpoint determination module 13 is specifically configured to determine whether the time difference is greater than a first preset time period; if it is greater than the first preset time period, it is determined that there is a breakpoint between the adjacent video time stamps.

[0075] In one embodiment, the traversal module 14 is specifically used to traverse the adjacent video timestamps where breakpoints exist, and record the breakpoint start timestamp and breakpoint end timestamp of each breakpoint; the breakpoint start timestamp of the breakpoint is the end timestamp of the previous video timestamp of the breakpoint; the breakpoint end timestamp of the breakpoint is the start timestamp of the current video timestamp of the breakpoint; the breakpoint start timestamp and the breakpoint end timestamp are converted into specific time to determine the video loss time period within the target time range.
