The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of systems and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The present disclosure provides an indexing method for video recording, the indexing method comprising: establishing a mapping relation (establishing a mapping relation S1) between a time period of video data and a file name and a storage path of camera ID and video data; during generation of the video data based on the video data acquired from the camera 11, the corresponding file name and save path of the video data are calculated based on the time period and camera ID of the video data and based on the mapping relationship, the video data are named as the corresponding file name and the video data are stored in the corresponding save path (write video data S2); and acquiring the time period and the camera ID of the video data to be read, and calculating the file name and the storage path of the video data to be read based on the mapping relation, thereby reading the video data to be read (reading the video data S3).
In some embodiments, the indexing method may further include: the time period of the video data to be deleted and the camera ID are acquired, and the file name and save path of the video data to be deleted are calculated based on the mapping relationship, thereby deleting the video data to be deleted (deleting the video data S4).
The present disclosure also provides a video recording device 10, where the video recording device 10 may include a camera 11 and a memory 12, the camera 11 may acquire video data (by live shooting) and store the video data in the memory 12 to generate recording data, and the video recording device 10 further includes: a mapping module 13, configured to establish a mapping relationship between a time period of video data and a file name and a storage path of the camera ID and the video data; a writing module 14 that calculates a corresponding file name and save path of the video data based on the time period and camera ID of the video data and on the mapping relationship established by the mapping module 13, names the video data as the corresponding file name and stores the video data in the corresponding save path, for example, in the memory 12, during generation of the video data; and a reading module 15 that acquires a time period of the video data to be read and the camera ID, and calculates a file name and a save path of the video data to be read based on the mapping relationship, thereby reading the video data to be read from, for example, the memory 12.
In some embodiments, the video recording apparatus 10 of the present disclosure may further include a deletion module 16, and the deletion module 16 may acquire a time period and a camera ID of the video data to be deleted, and calculate a file name and a saving path of the video data to be deleted based on the mapping relationship, so as to delete the video data to be deleted from, for example, the memory 12.
The camera 11 is used to take a video recording of a place to be monitored, thereby generating video data. The video data is transmitted to the memory 12 of the video recording device 10 by wire or wirelessly, and the video data is buffered to generate recording data. During the generation of the video data, the video data is divided into a plurality of time periods according to the time of shooting. For a particular piece of recorded data, the piece of recorded data can be uniquely determined by first determining the camera ID of the camera 11 and then determining the time period for which the recorded data is under the camera ID.
In the present embodiment, to index the recorded data, a mapping relationship is first established (S1). Specifically, a mapping relationship between the time slot of the recorded data and the camera ID, and the file name and save path of the recorded data is established. Preferably, the mapping is a functional mapping. By establishing the mapping relationship, a combination of a unique file name and a save path can be established for the video data in which the time period and the camera ID are determined. Preferably, the established mapping relationships may be stored in the memory 12 after the mapping relationships are established.
Subsequently, the video data is written (S2). Specifically, while the video data is generated based on the video data acquired from the camera 11, the video data is divided into video data of a plurality of time periods according to the shooting time, the camera ID of the camera 11 used and the time period information of a certain piece of video data are acquired, and the file name and the storage path of the piece of video data are acquired based on the mapping relationship established in the step of establishing the mapping relationship (S1). Then, the piece of recorded data is named in accordance with the obtained file name and saved in accordance with the obtained saving path, for example, in the memory 12. In the same manner, based on the mapping relationship, file names and saving paths of the video data of other time periods are obtained, and the corresponding pieces of video data are named according to the obtained file names and saved in, for example, the memory 12 according to the obtained saving paths. In this way, the correspondence relationship between a series of video data and time information has been abstracted as a map.
When the written video data needs to be read, the step (S3) of reading the video data can be implemented as follows. Firstly, the camera ID and the time period of the video data to be read are determined, the file name and the saving path of the video data to be read are calculated according to the established mapping relation, and the video data corresponding to the calculated file name and the saving path are found by matching the calculated file name and the saving path with the file name and the saving path of each piece of video data determined in the step (S2) of writing the video data, so that the video data can be read.
In some embodiments, it is also necessary to delete the written video data, which may be implemented by the following step (S4) of deleting the video data. Determining the camera ID and the time period of the video data to be deleted, calculating the file name and the saving path of the video data to be deleted according to the established mapping relation, and matching the file name and the saving path of each piece of video data determined in the step (S2) of writing the video data with the file name and the saving path of the video data to find the video data corresponding to the calculated file name and the saving path, so that the video data can be deleted.
In the video recording apparatus 10, the camera 11 can communicate with other modules or devices in a remote manner. The mapping module 13, the writing module 14, the reading module 15 and the deleting module 16 may be implemented in any suitable form of software or hardware. In some embodiments, the mapping module 13, the writing module 14, the reading module 15, and the deleting module 16 may be implemented by a processor. In some embodiments, the memory 12 may be any suitable storage device such as a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or a semiconductor memory.
By the video recording index method and the video recording equipment 10, the index does not need to be updated in real time every time the video data are written, so that the access efficiency of the video data is improved. In addition, the problem that the video data cannot be accessed due to the problem of index occurrence is solved, and the video data exceeding the storage period can be automatically deleted, so that the utilization rate of the storage space is improved.
It is to be understood that the above embodiments are merely exemplary embodiments employed to illustrate the principles of the present disclosure, and that the present disclosure is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the disclosure, and these are to be considered as the scope of the disclosure.
