It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As shown in fig. 1, a first embodiment of the present application provides a method 1 for logistics video forensics, which is applied to a host device, and the method 1 includes:
s101, marking the video collected aiming at the target area by using the first identification to obtain a marked video.
For example, a video acquired by a target area is captured by a video acquisition device such as a camera, and the captured video is captured by the target area, and the capture range of the camera is greater than or equal to the target area, so that the entire target area is completely covered by the capture range of the camera. For a plurality of target areas, a first target area is captured with a first camera and a second target area is captured with a second camera, … …, with at least one camera being assigned to each target area. The first identifier may be serial number data, for example, serial numbers are marked on videos, a video shot by the first camera is marked as 1, a video shot by the second camera is marked as 2, … …, a marked video is obtained, and then the marked video is stored and the corresponding video can be quickly found according to the marked serial number during searching.
S102, identifying code scanning information from the code scanning device to obtain a second identifier and waybill identifier data; the second identification and the first identification have a corresponding relation.
For example, the code scanning device may be a code scanning gun, the code scanning information is obtained by scanning a two-dimensional code or a waybill bar code through the code scanning gun and is sent to the host device, and after the host device receives the code scanning information, the code scanning information is recognized to obtain a second identifier and waybill identifier data; the second identification is used for directly positioning the video acquisition equipment taking the area where the waybill bar code is located as the visual field of the video acquisition equipment, so that the fixed binding relationship between the code scanning gun and the camera is directly solved, and the defect that the code scanning gun and the camera are fixedly bound in the prior art is overcome. Each second identifier is used for correspondingly marking the visual field of one video acquisition device; when the code scanning device is used for scanning the waybill bar code in the visual field of the video acquisition equipment, the video acquisition equipment acquires a video, the first identification is used for marking the video in the visual field shot by the video acquisition equipment, and thus the first identification and the second identification establish an incidence relation through the video acquisition equipment, namely the first identification is used for marking the video acquired by the video acquisition equipment in the visual field, and the second identification is used for marking the video acquisition equipment with the visual field covering the visual field.
In some embodiments, there is a correspondence between the second identifier and the first identifier, including: the first identifier includes first data, the second identifier includes second data, and the first data matches with the second data, for example, the first data is identical to the second data, or there is a corresponding relationship between the first data and the second data that meets a certain predetermined rule. For example, the first data are sequence numbers 1, 2, 3 … …, etc., and the second data are sequence numbers 1, 2, 3 … …, etc., then the second data are corresponding to and equal to the first data.
For example, the second identifier may be in the form of data such as "scan gun _ lane 1", "scan gun _ lane 2", "scan gun _ lane 3", and the waybill identifier data is data such as "5810243457130", "6721351346221". Correspondingly, the first identifier may be in the form of data such as "video _ channel 1", "video _ channel 2", "video _ channel 3", and the like. Data such as "channel 1", "channel 2", "channel 3" are used to label the first camera, the second camera, and the third camera, respectively. Thus, data such as "scan gun _ channel 1", "scan gun _ channel 2", "scan gun _ channel 3" and the like are associated one-to-one with data such as "video _ channel 1", "video _ channel 2", "video _ channel 3" and the like by data such as "channel 1", "channel 2", "channel 3" and the like for the mark camera.
When the code scanning information is identified, the code scanning information is analyzed according to a protocol to obtain a second identifier and waybill identifier data so as to carry out different processing on the two kinds of data subsequently, wherein the second identifier is used as a search mark.
S103, according to the sequence obtained by recognition, marking a plurality of waybill identification data obtained before and/or after the second identification is obtained by the second identification.
Specifically, the second identifier and the waybill identifier data are divided according to the sequence of the second identifier and the waybill identifier data obtained through identification, so that the second identifier and the waybill identifier data corresponding to the same target area belong to the same set, and the second identifier is used as a search mark, so that the waybill identifier data in the same set can be searched through the second identifier. The code scanning information is identified in the same order as the code scanning information received by the host device from the code scanning device, namely, the code scanning information received first is identified first. The host device receives the code scanning information from the code scanning device in the same order as the code scanning device sends the code scanning information. For example, when the preset code scanning sequence is that a two-dimensional code is read first and then an waybill barcode in the target area is read, as long as the second identifier is identified, it can be known that all waybill identifier data obtained by analyzing after the second identifier are obtained by scanning the waybill barcode in the corresponding target area, that is, the second identifier and all the waybill identifier data after the second identifier are grouped into the same set, and then the second identifier is used as a mark, so as to search the waybill identifier data of the set. The meaning of "dividing" is to establish an association relationship between the second identifier and the waybill identification data so as to search the waybill identification data through the second identifier, and the meaning of "same set" is to refer to an association relationship. For example, after the code scanning gun _ channel 2 is identified, ten waybill identification data such as 5810243457130 and 6721351346221 are identified, and then the code scanning gun _ channel 3 and twenty waybill identification data are sequentially identified, so that the code scanning gun _ channel 2 and the ten waybill identification data after the code scanning gun _ channel 2 are divided into a group, the ten waybill identification data take the code scanning gun _ channel 2 as a search mark for searching, namely, an association relationship is established between the code scanning gun _ channel 2 and the ten waybill identification data after the code scanning gun _ channel 2, and the ten waybill identification data are conveniently searched through the code scanning gun _ channel 2; dividing the code scanning gun _ channel 3 and twenty pieces of freight note identification data after the code scanning gun _ channel 3 into a group, and taking the twenty pieces of freight note identification data as a search mark for searching. The second identification and the waybill identification data corresponding to the same target area are consecutively adjacent in recognition order.
S104, finding the first identifier corresponding to the second identifier, and overlaying the corresponding waybill identification data (namely the waybill identification data in the set where the second identifier is located) to the marked video marked by the first identifier to obtain the video overlaid with the waybill identification data;
for example, for the second identifier "sweep code gun _ channel 2", find that the first identifier "camera _ channel 2", "sweep code gun _ channel 2" and "camera _ channel 2" are corresponding, superimpose the waybill identification data marked with "sweep code gun _ channel 2" onto the marked video marked with "camera _ channel 2", to obtain the video on which the waybill identification data is superimposed.
And S105, storing the video on which the waybill identification data is superimposed.
In certain embodiments, the method 1 further comprises: s106, finding the video superimposed with the waybill identification data according to the waybill identification data and playing the video.
In some embodiments, the correspondence between the second identifier and the first identifier includes: the first identification comprises first data, the second identification comprises second data, and the first data is matched with the second data. For example, the first data and the second data are identical, or there is a correspondence relationship between the first data and the second data that meets a certain predetermined rule. For example, the first data are sequence numbers 1, 2, 3 … …, etc., and the second data are sequence numbers 1, 2, 3 … …, etc., then the second data are corresponding to and equal to the first data.
According to the logistics video evidence obtaining method provided by the embodiment, the first identification mark is used for a video collected in a target area, the second identification is used as a searching mark of corresponding waybill identification data, the first identification corresponding to the second identification is searched, the waybill identification data is superposed on the corresponding marked video, the video superposed with the waybill identification data is obtained, a code scanning device and a video collecting device do not need to be in one-to-one correspondence, logistics video evidence obtaining can be carried out by using one code scanning device to correspond to a plurality of video collecting devices, the application flexibility is good, the cost is reduced, and the working efficiency is higher.
As shown in fig. 2, this embodiment further provides a device for logistics video forensics, including:
the marking module 10 is configured to mark a video acquired for a target area with a first identifier to obtain a marked video;

and the storage module 14 is used for storing the video overlaid with the waybill identification data.
In certain embodiments, the apparatus 01 further comprises:
and the playing module 15 is configured to find the video on which the waybill identification data is superimposed according to the waybill identification data and play the video.
As shown in fig. 3, a second embodiment of the present application provides a method 2 for logistics video forensics, including:
s201, a video acquisition device acquires a video aiming at a target area and sends the acquired video.
For example, the video capture device may be a camera, and a video capture device such as a video camera may capture a video of the target area, where the capture range of the camera is greater than or equal to the target area. For a plurality of target areas, a first target area is captured with a first camera and a second target area is captured with a second camera, … …, with at least one camera being assigned to each target area.
S202, the host equipment receives the video, and marks the video by using the first identification to obtain a marked video.
The host device includes a processor and a memory.
The first identifier may be number data, for example, a serial number is marked on a video, a video shot by the first camera is marked as 1, and a video shot by the second camera is marked as 2, … …, and then the video is stored, and when the video is searched, the corresponding video can be quickly searched according to the marked serial number.
S203, the code scanning device scans the graphic identifiers and the waybill identifiers located in the target area according to a preset scanning sequence to obtain code scanning information, and sends the code scanning information.
The code scanning device can be a code scanning gun. The order in which the scan information is transmitted is the same as the scan order.
In some embodiments, the predetermined scan order is to scan the graphic identifiers first and then scan all waybill identifiers in the target area. Alternatively, other scanning orders may be predetermined, such as scanning three (or other number) waybill identifiers first, then scanning the graphical identifiers, and then scanning the other waybill identifiers in the corresponding target area.
In some embodiments, the graphical identifier is a two-dimensional code and the waybill identifier is a waybill barcode. The waybill barcode is located within the target area, for example, where the item bearing the waybill barcode is placed. When the code scanning gun is used for scanning the waybill bar code in the target area, the camera corresponding to the target area shoots a video aiming at the target area, and the video is shot through the action of scanning the waybill bar code by the scanning gun. The graphic identifier (namely, the two-dimensional code) is manufactured in advance and carries graphic identifier data, the code scanning gun scans the two-dimensional code to obtain code scanning information, namely, the graphic identifier data, the code scanning gun scans the freight note bar code to obtain the code scanning information, namely, the freight note identifier data, and then the code scanning gun sends out the scanned code scanning information (comprising the graphic identifier data and the freight note identifier data) and sends the scanned code scanning information to the host equipment. The graphical identifier may be in other forms than a two-dimensional code. The waybill identifier can be in other forms besides a bar code.
S204, the host equipment identifies code scanning information from the code scanning device to obtain a second identifier and waybill identifier data; the second identification and the first identification have a corresponding relation.
In some embodiments, there is a correspondence between the second identifier and the first identifier, including: the first identifier includes first data, the second identifier includes second data, and the first data matches with the second data, for example, the first data is identical to the second data, or there is a corresponding relationship between the first data and the second data that meets a certain predetermined rule. For example, the first data are sequence numbers 1, 2, 3 … …, etc., and the second data are sequence numbers 1, 2, 3 … …, etc., then the second data are corresponding to and equal to the first data.
In some embodiments, the predetermined reading sequence is to read the graphic identifier first and then read all waybill identifiers in the target area, such that the receiving sequence is to receive the scan information (i.e., graphic identifier data) corresponding to the graphic identifier first and then receive the scan information (i.e., waybill identifier data) corresponding to the waybill identifier, and the host device identifies the scan information in the same order as the receiving sequence.
The form of the code scanning information obtained by the scanning gun scanning the two-dimensional code is data such as "code scanning gun _ channel 1", "code scanning gun _ channel 2", "code scanning gun _ channel 3", and the code scanning information obtained by the code scanning gun scanning the waybill barcode is data such as "5810243457130", "6721351346221".
And identifying the graphic identifier data to obtain a second identifier, and identifying the waybill identifier data to obtain waybill identification data. The sequence of the second identification and the waybill identification data obtained by identifying the code scanning information is the same as the preset sequence of reading the graphic identifier and the waybill identifier. And analyzing the code scanning information according to the protocol to obtain a second identifier and waybill identifier data so as to carry out different processing on the two kinds of data subsequently, wherein the second identifier is used as a search mark.
S205, the host device marks a plurality of pieces of waybill identification data obtained before and/or after obtaining the second identification by using the second identification according to the sequence obtained by identification.
For example, when the preset code scanning sequence is that the two-dimensional code is read first and then the waybill barcode is read, as long as the second identifier is identified, all waybill identification data identified after the second identifier corresponds to the waybill identifier in the corresponding target area, the second identifier and all waybill identification data identified later can be divided into the same set, and then the second identifier is used as a mark, namely, the association relationship between the second identifier and the waybill identification data identified later is established, so that the waybill identification data of the set can be searched. The meaning of dividing is to establish an association relationship between the second identifier and the waybill identifier data so as to realize that the waybill identifier data can be found through the second identifier, and the meaning of the same set is an association relationship. For example, after the code scanning gun _ channel 2 is identified, ten pieces of waybill identification data such as 5810243457130 and 6721351346221 are identified, and then the code scanning gun _ channel 3 and twenty pieces of waybill identification data are identified in sequence, then the code scanning gun _ channel 2 and the next ten pieces of waybill identification data are divided into a group, the ten pieces of waybill identification data use the code scanning gun _ channel 2 as a search mark for searching, the code scanning gun _ channel 3 and the next twenty pieces of waybill identification data are divided into a group, and the twenty pieces of waybill identification data use the code scanning gun _ channel 3 as a search mark for searching. The sequence of code scanning information received by the host device is the same as the identification sequence and the code scanning sequence of the code scanning gun.
Alternatively, other scanning orders may be set, for example, three (or other number) waybill identifiers are scanned first, then the graphic identifier is scanned, then other waybill identifiers in the corresponding target area are scanned, and then when the waybill identification data is searched, as long as the second identifier is found, the three waybill identification data before the second identifier and the waybill identification data after the second identifier are known to correspond to the second identifier.
S206, the host device finds the first identifier corresponding to the second identifier, and superimposes the corresponding waybill identifier data (namely, the waybill identifier data in the set where the second identifier is located) on the marked video marked by the first identifier to obtain the video on which the waybill identifier data is superimposed.
For example, for the second identifier "sweep code gun _ channel 2", find that the first identifier "camera _ channel 2", "sweep code gun _ channel 2" and "camera _ channel 2" are corresponding, superimpose the waybill identification data marked with "sweep code gun _ channel 2" onto the marked video marked with "camera _ channel 2", to obtain the video on which the waybill identification data is superimposed.
And S207, the host equipment stores the video on which the waybill identification data is superposed.
In certain embodiments, the method 2 further comprises: s208, the playing device finds the video overlaid with the waybill identification data according to the waybill identification data and plays the video.

The code scanning information receiving unit is used for monitoring the connection of the code scanning device and receiving the code scanning information data sent by the code scanning device.
The code scanning protocol analysis unit is used for analyzing the code scanning information data according to a code scanning protocol so as to judge whether the code scanning information data is camera channel mapping data (namely data carried by the two-dimensional code, such as a camera channel number) or article waybill barcode data, and distinguishing and processing the code scanning information data.
The superposition unit is used for superposing the waybill barcode information to a video shot by a corresponding camera in an OSD mode. OSD, i.e. On-Screen Display, i.e. a Screen menu type adjustment mode.
The storage unit is used for writing the video and the analyzed code scanning information data into a hard disk for storage.
The search playback unit is used for retrieving and playing back the corresponding video according to the code scanning information data (such as the waybill number information).
The use scenario of the device is shown in fig. 6, which is a schematic view of a scenario in a logistics warehouse; the area needing code scanning in the actual scene can be covered by the camera, the four triangular areas in fig. 6 are only a simple example, the angle which can be acquired by the camera is larger in practice, the actual scene is not necessarily a rectangle like in fig. 6, more possibility is a polygonal area, and the video acquisition area of the camera can also be a polygon. In fact, coverage areas among different video cameras are overlapped, when the code scanning information is superposed to the collected video, only the code scanning picture is collected by the superposed video, and which video is selected among the overlapped cameras is only required to be selected without influencing evidence obtaining.
The method includes the steps that a plurality of two-dimensional codes are manufactured in advance, data with a specific format are obtained after code scanning, and the two-dimensional codes can be distinguished from waybill bar codes through the data with the specific format, for example, the data include marks such as 'code scanning gun _ channel 1', 'code scanning gun _ channel 2' and 'code scanning gun _ channel 3'. The two-dimensional code carries data for marking a camera channel number.
The code corresponding to the data obtained by scanning at this time can be distinguished by a code scanning protocol analysis unit as a two-dimensional code or a waybill bar code, and then a channel number contained in the data is extracted so as to determine a camera channel superposed when a subsequent waybill bar code is bound after the code is scanned.
And attaching the prepared two-dimensional code to a prominent position of each area, such as a column in the target area, wherein the camera channel represented by the two-dimensional code corresponds to the camera actually covered. When the code scanning person walks to switch the camera area, the two-dimensional codes are scanned first, and then the waybill bar code scanning operation is carried out. The camera channel is a kind of identification information.
The code scanning device can be a code scanning gun. The fields contained in the protocol for the scan gun to send data include camera channel code information or waybill bar code information, and may also include a scan gun ID (for identifying the unique scan gun) to indicate the source of the data.
After receiving the data, the code scanning protocol analysis unit judges whether the received data is data carried by the two-dimensional code or waybill barcode data according to the aforementioned data characteristics (such as the code scanning gun in the code scanning gun _ channel 1). After receiving the data carried by the two-dimensional code, setting a camera channel bound by the bar code data corresponding to the code scanning gun ID as a camera obtained by analyzing the two-dimensional code data (such as a channel 1 in a code scanning gun _ channel 1). When the bar code data are received, the binding relation set before is searched according to the ID of the code scanning gun, the corresponding camera channel is found, and subsequent superposition and video recording processing are carried out.
The method comprises the steps of preparing a two-dimensional code carrying camera features in advance (data are set according to a specific format, can be distinguished to be not freight bill bar codes and can extract camera channel information) and pasting the two-dimensional code carrying the camera features at a conspicuous position in a shooting area of a corresponding camera, scanning the two-dimensional code carrying the camera features to determine the corresponding camera, scanning freight bill bar codes, scanning the two-dimensional code corresponding to the camera features of another camera after a code scanning operator moves to the target area of the camera, analyzing the data by a host device, identifying whether the data corresponding to the two-dimensional code or the data corresponding to the freight bill bar codes according to the data features, superposing the scanned freight bill bar code information to a video shot by the corresponding camera and storing the data for later evidence obtaining and using.
The technical scheme of the embodiment solves the problem that one code scanning device cannot simultaneously correspond to a plurality of cameras for use, is suitable for more application scenes, only needs to make a plurality of codes in advance and scan code protocol definition analysis, and is low in overhead and almost free of additional cost.
