DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0020] It should be noted that, in the description of the present invention, the terms "first" and "second" are only for the convenience of description, and do not indicate or imply the relative importance of the devices, elements or parameters, and therefore cannot be understood as limiting the present invention. In addition, the term "and / or" in the present invention is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0021] Figure 1 Schematic diagram of the main steps of the first embodiment of the live broadcast data statistics method of the present invention. Figure 1 As shown, the method of this embodiment includes steps A10-A40: Step A10: Record the live broadcast room video in segments according to the preset recording time length.

[0022] In this embodiment, the preset recording time length is 15 minutes.

[0023] Step A20: Use face recognition technology to determine whether there is a change of live broadcast personnel in each recorded video clip. If yes, find the time of the change. This step may specifically include steps A21-A23: Step A21: For a certain video clip, select the first face image and the last face image.

[0024] Step A22, determine whether the first face image and the last face image belong to the same live broadcast person; if so, it is considered that there is no phenomenon of changing the live broadcast person in the video clip; otherwise, it is considered that there is the phenomenon of changing the live broadcast person.

[0025] Step A23: If there is a phenomenon of changing the live broadcast personnel, then search for the time of the change in the video clip based on the binary search method. This step can further include steps A231-A234: Step A231, record the first frame time and the last frame time of the video clip as the start time start and the end time end respectively.

[0026] Step A232, taking the middle time mid between the start time start and the end time end; Step A233, comparing the face image at the middle time mid in the video clip with the face image at the start time start, if they belong to the same person, updating the start time start with the value of the middle time mid; otherwise, updating the end time end with the value of the middle time mid; Step A234, repeat steps A232 to A233 until the time between the start time start and the end time end is less than the threshold, and the middle time mid value at this time is the substitution time.

[0027] In this embodiment, the threshold is set to 60 seconds, which means that the substitution time is accurate to the minute.

[0028] Step A30: Determine the start and end time of each live broadcast staff member according to the replacement time found and the first frame time and the last frame time of all video clips. This step may specifically include steps A31-A34: Step A31: record the first frame time of the first video clip as the start time of the first live broadcaster.

[0029] Step A32: If there is a change of live broadcast personnel in the first video clip, the corresponding replacement time is recorded as the off-broadcast time of the first live broadcast personnel and the on-broadcast time of the second live broadcast personnel; otherwise, the last frame time of the video clip is recorded as the off-broadcast time of the first live broadcast personnel.

[0030] In this embodiment, the "first live broadcast personnel", "second live broadcast personnel", etc. are defined based on the time sequence in which these personnel conduct live broadcasts, and does not exclude the situation where the first live broadcast personnel and a subsequent live broadcast personnel (such as the fourth live broadcast personnel) are the same person.

[0031] Step A33: If there is a change of live broadcast personnel in the second video clip, the corresponding change time is used to update the off-broadcast time of the previous live broadcast personnel, and the change time is recorded as the on-broadcast time of the next live broadcast personnel; otherwise, the last frame time of the video clip is used to update the off-broadcast time of the previous live broadcast personnel.

[0032] In this embodiment, the live broadcast staff before the substitution time is called the "previous live broadcast staff", and the live broadcast staff after the substitution time is called the "next live broadcast staff". Therefore, the "previous live broadcast staff" and the "next live broadcast staff" only indicate that the order of appearance of these two staff in the current video clip is different.

[0033] Step A34: Process each subsequent video clip with reference to step A33 until the start and end time of each live broadcast staff within the preset time range is determined.

[0034] In this embodiment, the preset time range is one day, and the video recording starts from the start of the live broadcast room in the morning until the live broadcast room is closed in the evening, and the start and end time of each live broadcast person in this day is determined.

[0035] Step A40: Count the live broadcast data of each anchor according to the broadcast time and the broadcast time.

[0036] During the live broadcast, the host may need to leave for a short period of time due to some emergency matters. In this case, a substitute arranged by him / her can take his / her place to continue the live broadcast.

[0037] There are two cases in step A40: one is to consider the phenomenon of proxy broadcasting, in which case the live broadcast data of the proxy broadcaster during the live broadcast is combined with the live broadcast data of the replaced anchor; the other is to not consider the phenomenon of proxy broadcasting, and each live broadcaster is regarded as a separate anchor. The following are respectively explained.

[0038] (I) In the case of considering the proxy broadcast phenomenon, step A40 may include A41-A42: Step A41, identifying the anchor and the proxy, and using the proxy's off-air time to update the corresponding anchor's off-air time. This step may specifically include steps A411-A414: Step A411: Calculate the length of the live broadcast time of each live broadcast staff member according to the start and end broadcast time of the live broadcast staff member.

[0039] Step A412: record the first live broadcaster as the first anchor.

[0040] In this embodiment, "the first anchor" and "the second anchor" only represent the time sequence of these anchors' live broadcast activities, and it does not exclude the situation that the first anchor and the second anchor are the same person.

[0041] Step A413: If the first anchor sets the proxy broadcast duration, and the live broadcast time of the second live broadcaster is less than or equal to the proxy broadcast duration, the second live broadcaster is considered to be the proxy broadcaster, and the off-broadcast time of the first anchor is updated with the off-broadcast time of the proxy broadcaster, and the third live broadcaster is recorded as the second anchor; otherwise, the second live broadcaster is recorded as the second anchor.

[0042] In this embodiment, the program allows a host to set whether to enable proxy broadcasting and set the proxy broadcasting duration according to actual conditions.

[0043] Step A413: If the second anchor sets the substitute broadcast duration, and the live broadcast time of the next live broadcaster is less than or equal to the substitute broadcast duration, the next live broadcaster is considered to be the substitute broadcaster, and the off-broadcast time of the second anchor is updated with the off-broadcast time of the substitute broadcaster, and the next live broadcaster is recorded as the third anchor; otherwise, the next live broadcaster is recorded as the third anchor.

[0044] In this embodiment, "the next live broadcast person" and "the next live broadcast person" refer to the first and second live broadcast persons who perform live broadcast immediately after the second anchor, respectively.

[0045] Step A414: for each subsequent anchor, refer to step A413 to determine whether the proxy broadcast duration is set and perform corresponding processing until all proxy broadcast personnel are identified and the corresponding anchor's off-air time is updated.

[0046] Step A42: According to the start and end time of each anchor, the live broadcast data in the corresponding time period is searched and counted.

[0047] In this step, the situation where the same person broadcasts live multiple times can be taken into account. For example, if the first broadcaster and the fourth broadcaster are the same anchor, the data of these two broadcasts can be combined and calculated.

[0048] Among them, live broadcast data includes: number of completed orders, total commodity transaction amount, page views, number of unique visitors and advertising volume.

[0049] (II) If the proxy broadcast phenomenon is not considered, step A40 may include A45-A46: Step A45, record each live broadcaster as an anchor; Step A46: According to the start and end time of each anchor, the live broadcast data in the corresponding time period is searched and counted.

[0050] In this step, the situation where the same anchor broadcasts live multiple times can be taken into account. For example, if the second anchor and the sixth anchor are the same person, then the data of these two live broadcasts can be combined and calculated.

[0051] Among them, the live broadcast data includes: the number of completed orders, the total transaction amount of goods, the number of page views, the number of unique visitors and the amount of advertising.

[0052] Figure 2 Schematic diagram of the main steps of the second embodiment of the live broadcast data statistics method of the present invention. Steps B10, B30, and B40 in this embodiment correspond to A10, A30, and A40 in the above embodiment 1 respectively. The difference between step B20 and step A20 in embodiment 1 is that in addition to finding the time of the substitution when a person is replaced in the live broadcast room, a reminder message is also sent in B20. Figure 2 As shown, the method of this embodiment includes steps B10-B40: Step B10: Record the live broadcast room video in segments according to the preset recording time length.

[0053] Step B20: Use face recognition technology to determine whether there is a change of live broadcast personnel in each recorded video clip. If so, find the time of the change and send a reminder message.

[0054] The reminder information may include: the ID of the previous live broadcaster, the ID of the next live broadcaster, and the time of replacement, etc.

[0055] Step B30: Determine the start and end time of each live broadcast staff member according to the found replacement time and the first frame time and the last frame time of all video clips.

[0056] Step B40: Count the live broadcast data of each anchor according to the broadcast time and the broadcast time.

[0057] In some implementations, step B10 may be executed by the first thread, step B20 may be executed by the second thread, and step B30-B40 may be executed by the third thread, so as to realize checking whether a person is replaced while recording, and sending a reminder message when a person is replaced.

[0058] In the above-mentioned Embodiment 1 and Embodiment 2, although each step is described in the above-mentioned chronological order, those skilled in the art can understand that in order to achieve the effect of this embodiment, different steps do not have to be executed in such an order, and they can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of the present invention.

[0059] Based on the above method, the present invention also provides an embodiment of an electronic device. The electronic device of this embodiment includes a memory and a processor. The memory stores a computer program that can be loaded by the processor and execute the method as described above.

[0060] Furthermore, the present invention also provides an embodiment of a computer-readable storage medium, in which the storage medium of this embodiment stores a computer program that can be loaded by a processor and execute the method described above.

[0061] The computer-readable storage medium may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and other media that can store program codes.
