[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are for convenience only to describe the present invention without requiring the present invention to be necessarily constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

In the embodiments of the present invention, the expression of "platform" and "server" is the same meaning, and the "cloud" is a description manner made in compliance with the trend of big data, and in some small-sized applications, the "cloud" may also be embodied as "server" itself; in a large application occasion, the cloud end more refers to servers with professional storage functions, and compared with a platform, the cloud end plays a more supporting role in video stream storage of the cloud end.

In the embodiment of the present invention, the character a is used only for convenience of description (convenience of transfer) and for embodying an object having a specific meaning, and does not bring a special meaning limitation by itself, but limits the meaning by the literal content of the definition.

In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1:

the embodiment 1 of the present invention provides a shared video-based communication method, where a communication video of each expert recorded by a platform is stored in a cloud, and one or more content index nodes are distributed in the communication video, as shown in fig. 1, the communication method includes:

in step 201, an instruction for a user to call an alternating current video is obtained, and text content of a content index node of the alternating current video stored in the cloud is called according to the instruction.

When the instruction can include one or more keywords, the server screens text contents of content index nodes of the alternating-current video stored in the cloud according to the one or more keywords, and feeds the screened text contents of the content index nodes back to the intelligent terminal operated by the user. For example: the instruction for calling the communication video is the '@ video', namely when the server detects that the user inputs the content of the '@ video', the server calls the content index node related information of the communication video stored in the cloud, and the information is preferably displayed on the intelligent terminal of the user according to a preset presentation format.

In step 202, the text content is fed back to the intelligent terminal sending the instruction in a preset presentation format.

Wherein, the preset presentation format comprises: the method comprises the steps that an alternating-current video author or an alternating-current video theme is taken as a first level, content type division of content index nodes in an alternating-current video is taken as a second level, specific content of each content index node is taken as a third level, and text content corresponding to each alternating-current video stored in a cloud is presented as a tree according to distribution of each level; wherein, the text content in each level can be expanded and folded, so that the user can complete the corresponding interaction; in practical cases, the corresponding hierarchy may be further subdivided according to the actual classification, which is not listed here. As shown in fig. 2, the user is editing the communication content of a certain discussion topic; as shown in fig. 3, when a user inputs "@ video" into an editing window of the platform, the platform generates a sub-window on the communication interface, the sub-window may be set at any position on the interface, and the content of the content index node in the sub-window is presented in an expandable-foldable tree-like manner, as shown in fig. 4, an effect diagram of the content index node is presented for several trees, wherein buttons with arrows are configured for the expandable-foldable branches, so that the user completes expansion and folding of the corresponding branches by clicking the corresponding buttons with arrows.

In step 203, receiving an operation of selecting a text of a content index node corresponding to a video by a user, and feeding back video browsing content near the corresponding content index node to the intelligent terminal.

The operation of receiving the text of the content index node of the corresponding video selected by the user comprises the following steps:

the user points to an index node and completes double-click action; or, the user selects an index node and drags the index node to the browse window; or, the user selects an index node and selects a video playing and browsing option from the skipped operation list by long pressing.

Taking fig. 5 as an example, double-clicking on an index node can reduce the probability of no operation compared with a single-click operation, after a user double-clicks on an index node (also referred to as a leaf node) in fig. 5, the outer frame of the corresponding index node is prominently presented (for example, the frame shown in fig. 5 is bold), and a sub-window is generated to carry the loaded video segment and support the related operation of determining the content of the summary link by the subsequent user. Wherein, without special limitation, the secondary window can be arranged at any position in the interface, and fig. 5 only shows one way of arranging the secondary window.

In step 204, an intercepting instruction including a video start node and a video end node is obtained, a mapping relation with a corresponding communication video is generated, the mapping relation is converted into an abstract link and is displayed in a current communication window, so that other users trigger playing of video contents corresponding to the start node and the end node when clicking the abstract link.

The summary link is formed by a frame of picture A in the video content corresponding to the starting node and the ending node, corresponding time points of the starting node and the ending node, and a position address where the video content is stored; the frame of picture A is provided with a hyperlink, and the hyperlink is specifically represented by importing video contents of a starting node and an ending node according to the time points of the starting node and the ending node and the position address where the video contents are stored after the picture A is clicked.

As shown in fig. 5, the start node time and the end node time may be completed by selecting the corresponding video frame, or may be input through the related information editing window in the sub-window thereof, which is not limited herein.

The embodiment of the invention utilizes the characteristic that the content index node is text in the video with the content index node, firstly matches the content of the content index node through the index key words input by a user, switches to the video segment which establishes a mapping relation with the target content index node of the corresponding jump operation according to the jump operation of the user, and further determines the abstract link configured for the current communication window by the start-end time node configured by the user. Therefore, when other users browse the communication comments, the interaction with the video stored in the cloud can be quickly established through the abstract link, the communication form among the users is enriched, and the transmission speed of effective information is improved.

With reference to the embodiment of the present invention, in step 204, the selecting of the frame of picture a specifically includes at least one or more of the following manners:

in the first mode, a user manually selects one frame of picture in the video contents of the starting node and the terminating node as the picture A.

And secondly, identifying the current user's alternating text content by the server, matching the caption and/or content index node contained in each frame of picture according to the alternating text content, and taking the picture with the highest matching similarity as the picture A.

The method is a traditional generation method, which has the advantage of being convenient to implement, but cannot meet the requirement of users on rapid extraction of frequent data when pursuing increasing intellectualization. Therefore, the embodiment of the present invention further provides a second method, which effectively utilizes effective information contained between the content index node and the video subtitles (the generation of the subtitles thereof will be further described in embodiment 2), and can quickly and accurately extract one or more frames of pictures with the largest information amount or the closest relationship with the user expression viewpoint from a segment of video content. The inconvenience of requiring a user to make a choice of means in the first mode is simplified. In a preferred implementation, the first and second modes can be implemented in combination, and the priority of the first mode is higher than that of the second mode, that is, after the platform selects/recommends a frame of picture for the user, if the user is not satisfied, the user can further select the picture a approved by the user in the first mode.

In the embodiment of the invention, in a default condition, when a server detects that a certain webpage containing the abstract link is opened by a user, the server caches the corresponding video content according to the position address of the video content storage and the corresponding time points of the starting node and the ending node. On the other hand, however, some users' browsing habits tend to browse only the video content in the topics of the web pages, and switch to the video browsing interface when necessary, so that in the embodiment of the present invention, an extended function is further provided, wherein the user may preset to display only the text content when browsing the website content of the platform, and the server skips the operation of caching the video content for the website content when receiving the browsing request of the user. Therefore, the loss of resources for caching the video content by the server can be reduced, and the mode of browsing themes by the user can be enriched.

The use experience of the method and the server resource utilization in a specific implementation environment can be improved by combining various extensions made by the embodiment, but a preferable extension scheme also exists by combining the embodiment of the invention based on the use habit that other users possibly set only browse characters, so that the preliminary understanding of the meaning of the user to express the video segments quoted by the user can be further improved under the condition that the abstract links are not clicked by other users. Therefore, a preferred extension scheme exists in combination with the embodiment of the present invention, wherein the server is further configured to extract subtitle content in the video content of the start node and the end node, and use the subtitle content in a text form as a component of the abstract link or use the subtitle content in a text form as a text content for user communication.

Example 2:

an embodiment 2 of the present invention provides a method for generating a node tag in a recorded expert video, which is used to support an expert ac video used in embodiment 1, and as shown in fig. 6, the method includes:

in step 301, various tools used by experts in the recording environment are added with tag electronic devices, and the tag electronic devices are used for feeding back the types of the currently actuated tools to the platform when the corresponding tools are actuated by the experts.

After the server determines the type of the currently driven tool according to the wireless signal sent by the tag electronic device, the server may further formulate a collection strategy of relevant information of the corresponding tool, for example: the angle of shooting of the monitoring camera, the field of view size of shooting, the sensitivity and the collection cycle of the wireless signal of adjustment collection etc.. The sensitivity of the collected wireless signals and the adjustment of the collection period are also related to the richness degree of the process detail information capture of the tool used, and have a larger incidence relation with the related information of the corresponding tool which is finally analyzed.

In step 302, the platform confirms that the tool a is used according to a wireless signal fed back by the tag electronic device a on the tool a, and adds a node tag in a corresponding recorded video content; wherein the node label contains information about the use of the tool A by an expert.

Wherein, the related information of the tool A comprises: the length of time that tool a is used, the target object that is processed using tool a, the number of times tool a is used, one or more of other tool objects that are used in conjunction with tool a.

In the embodiment of the invention, corresponding professional tools are required to finish the interactive content with the crops in the found expert video, and the content is left in the prior art and is not effectively tracked. The platform realizes the judgment of the positions of the added nodes of the recorded monitoring video and the generation of the content of the added node labels according to the monitoring of the relevant information of the tool A used by the expert, and effectively improves the generation efficiency of the node labels in the expert video.

For the platform related in the embodiment of the present invention to confirm that the tool a is used according to the wireless signal fed back by the tag electronic device a on the tool a, at least two implementations are also provided:

in a first mode, a storage cabinet for placing the tool is provided with a wireless charging device and an external signal shielding function, and a platform side determines that the tool A is used according to an electronic tag number corresponding to a currently detectable wireless signal; when other tools are placed in the storage cabinet, the wireless signals emitted to the outside are shielded by the storage cabinet. Wherein, wireless charging device can guarantee that each label electronic equipment is in signal emission saturated condition constantly, can be when being taken out the use by the expert, and corresponding radio signal is gathered by the detection device of platform setting the very first time. Wherein, store up and receive the cabinet and can adopt the closed shell that tin, iron material made, and corresponding wireless charging device can adopt the industry ripe wireless means of charging, no longer describe here.

And in the second mode, the wireless signal receiver on the platform side has a signal strength detection function, the wireless signal receiver periodically receives the wireless signals returned by the tag electronic equipment on each tool, the camera shoots that the expert enters the monitoring area, and when the strength of the wireless signal sent by the tag electronic equipment A on the tool A changes, the tool A is determined to be used.

In order to ensure the accuracy of detecting the change of the wireless signal strength of the equipment, it is preferable to arrange at least three wireless signal collectors in the monitoring area, so that the position coordinates of the tool a in the monitoring area can be calculated based on the known coordinates of the three wireless signal collectors even by the principle that three points form one surface.

In embodiment 1 of the present invention, mainly an electronic tag device with a wireless signal transmitting function is added to a tool used by an expert, and in an actual implementation process, for an agricultural video, besides the tag content in the expert video can be automatically generated by taking reference to the electronic tag device in embodiment 1, a feature judgment of a growth stage specific to an agricultural crop can be further adopted to generate the tag content of a node tag belonging to the growth stage, as shown in fig. 7, the generating method further includes:

in step 303, the platform matches the photographed crops by using the crop features of the corresponding growth stages when the currently photographed crops enter the growth stage time interval according to the currently recorded growth stage distribution information of the crop varieties and the crop features of each growth stage, and configures the node tags of the growth stages for the correspondingly photographed screens when the similarity of the matching results is greater than a preset threshold.

In the above process of setting node labels corresponding to growth stages according to the growth stages of crops, the same crop may also be changed correspondingly due to different geographic locations of experts for cultivating the same crop, and at this time, if a user is involved to browse videos of a certain crop, it is preferable to return a monitoring video matched with the position information of the crop, so as to be better effective for obtaining effective information from the video, therefore, in combination with the method in step 303 of the embodiment of the present invention, there is also a preferred implementation scheme, as shown in fig. 8, and the generating method further includes:

in step 304, after acquiring the recorded videos of different experts for the same crop type, the platform establishes a distribution relationship of node tags of the recorded videos and corresponding to corresponding growth stages of the same crop type according to different geographical positions of the experts.

In step 305, according to the distribution relationship, when the user queries the recorded video of the corresponding crop, the video content with the same crop type and the highest region position similarity is returned to the user.

For the expert video, as long as the expert video is not published on the platform, there is room for adjustment and modification, so if the growth stage obtained by the current matching result skips the theoretically previous growth stage, the generation method further includes:

tracing back the video content between the last growth stage node and the growth stage node obtained by the current matching result; and again using a second video in between for feature matching, where the second video originates from a camera from another perspective. In the above manner, the requirement of providing at least two cameras in the monitoring area is provided, which is actually also a preferable solution proposed for making the label associated with the node label in the growing stage, because the growing node is captured by analyzing the image characteristics of the crops in the picture captured by the cameras, which is different from the label electronic device in embodiment 1, and the image capture may cause the analysis deviation due to the difference of the capturing view angle, and therefore, the provision of at least two cameras in the monitoring area is a preferable implementation solution.

In the traditional mode, the excerpted notes of experts exist in the form of paper texts, and are actually a big loss of effective information in the internet era. Even though some platforms have introduced a way for computer entry, it is still not associated with video tagging. In the embodiment of the invention, a preferable expansion scheme is provided, specifically, relevant information in the excerpted note of the expert is obtained, and the time node for adding the node tag in the agricultural video of the value is determined according to the relevant information. The server further analyzes the recorded video segments according to the content of the relevant information after obtaining the relevant information in the extracted note, and determines the video frame where the relevant information is located from the corresponding video segments through image identification, so that the confirmation of the time node added with the node label is completed.

In actual operation, the possibility of information interaction exists between monitoring videos of different experts, particularly in an application example of making labels for growth nodes of crops, because growth solar terms of the same crop have high relevance, in the concrete implementation, regional information of the growth node labels is marked earliest in a batch of expert videos corresponding to the same crop, and growth nodes in videos of other regions are calculated according to the regional information, so that the analysis range of a platform for the growth nodes in the videos of other regions is updated.

In order to further improve the efficiency of tagging expert videos, it is also considered by the embodiment of the present invention that the activity of a general video browsing user is utilized, and therefore, a preferred implementation scheme exists in combination with the embodiment of the present invention, as shown in fig. 9, including:

in step 401, a request for adding a first node tag fed back by a user browsing a video is obtained.

The request for adding the first node label carries the name ID of the browsed video, time node information corresponding to the video frame added with the first node label, label content, user ID and the like. After obtaining the request for adding the first node label, the server correspondingly confirms the user authority according to the user ID, preferably, queries the user ID history according to the user ID, initiates the total times (also called total points) that the request for adding the first node label is finally classified into the conventional node label row and column of the video, so that the user ID with higher total score is set in the column to be checked in step 302, and then the corresponding first preset threshold value is decreased according to the preset proportion or the preset difference value (for example, the first preset threshold value is 90% of the first preset threshold value; or the first preset threshold value is-5, where 5 is the preset difference value), therefore, the request of adding the first node label of the user ID with better historical credit/professional degree is more quickly verified and passed.

In step 402, the first node tag is set in a to-be-checked column, and when the platform feeds back the video to other users, the platform receives a judgment of correctness of the first node tag by other users.

Preferably, for the judgment results of other users, the feedback correctness judgment of the other users can be given appropriate weighting according to the correctness total of the history judgment, that is, a weighting coefficient greater than 1 is multiplied, so that the efficiency of the verification of the request for adding the first node tag can be further improved.

In step 403, when the number of correct judgments corresponding to the first node tag reaches a first preset threshold and the ratio of the number of correct judgments to the number of incorrect judgments is greater than a second preset threshold, the first node tag is classified into a regular node tag row and column of the video.

The second preset threshold value ensures that the request for adding the first node label is verified incorrectly due to a single reference first preset threshold value when more actual judgments are wrong because the total cardinality is large enough. Thus, the robustness of the present implementation is further improved.

Example 3:

the present invention also provides a shared video-based communication apparatus, as shown in fig. 10, for implementing the shared video-based communication method described in embodiment 1, the apparatus includes:

at least one processor 21; and a memory 22 communicatively coupled to the at least one processor 21; wherein the memory 22 stores instructions executable by the at least one processor 21 and programmed to perform the shared video-based communication method of embodiment 1.
