[0032] Embodiment 1

[0033] Figure 1 FIG. 1 is a flowchart of a conference projection method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of projection based on multiple signal sources in a conference. The method can be executed by a conference projection device, which can be implemented in the form of hardware and / or software. The conference projection device can be configured in an electronic device, and the electronic device can be configured as a terminal or a projection device. As Figure 1 shown, the method includes:

[0034] S110. Determine the image information corresponding to each to-be-displayed signal source among at least one to-be-displayed signal source of the target conference.

[0035] In this embodiment, the target conference can be understood as the conference that needs to be projected and displayed currently. The to-be-displayed signal source can be understood as the signal source device that needs to be projected or displayed in the target conference. For example, the to-be-displayed signal source can be a laptop computer or a tablet computer, etc. The image information can be understood as the image data extracted from the signal of the to-be-displayed signal source.

[0036] Specifically, in the target conference, obtain the signals of at least one to-be-displayed signal source, and use a preset decoding algorithm to extract the image information from each to-be-displayed signal source. Among them, the preset decoding algorithm can be the Transition-Minimized Differential Signaling (TMDS) algorithm.

[0037] S120. Identify each piece of image information respectively to obtain the identification results of the to-be-displayed signal sources.

[0038] Specifically, a preset identification algorithm can be used to identify each piece of image information to determine the identification results of the to-be-displayed signal sources. Among them, the identification results can include but are not limited to the content information of the target conference, the conference process, and the participant information, etc. Among them, the participant information can include the positions and names of the participants. This embodiment does not limit the specific preset identification algorithm. For example, the preset identification algorithm can be a neural network, or a machine learning algorithm (such as a support vector machine, a decision tree, and a random forest, etc.), or a rule-based identification method (such as template matching, feature extraction and matching, etc.).

[0039] S130. Determine the to-be-displayed signal source with the highest priority according to the identification results, where the priority is determined based on the relevance between the to-be-displayed signal source and the reserved conference theme of the target conference.

[0040] In this embodiment, the reserved meeting theme can be understood as the core topic or key discussion point of the target meeting set in advance. The relevance between the signal source to be displayed and the reserved meeting theme of the target meeting is used to measure the matching degree between the signal source to be displayed and the reserved meeting theme.

[0041] Specifically, for each recognition result among the recognition results, using a preset relevance algorithm, calculate the relevance between the signal source to be displayed corresponding to the current recognition result and the reserved meeting theme; furthermore, based on the relevances, perform a priority ranking on the signal sources to be displayed, and determine the signal source to be displayed with the highest priority. In this embodiment, the preset relevance algorithm includes, but is not limited to, a text matching algorithm, a semantic recognition algorithm, and a relevance evaluation algorithm based on rules. It should be noted that the higher the relevance, the higher the corresponding priority.

[0042] S140. Perform a projection display based on the signal source to be displayed with the highest priority.

[0043] Specifically, after determining the signal source to be displayed with the highest priority, automatically retrieve the signal of this signal source, and display this signal on the projection screen through a projection device.

[0044] The technical solution provided in the first embodiment of the present invention determines the image information corresponding to each signal source to be displayed among at least one signal source to be displayed for the target meeting; respectively recognize each image information to obtain the recognition results of the signal sources to be displayed; determine the signal source to be displayed with the highest priority according to the recognition results, where the priority is determined based on the relevance between the signal source to be displayed and the reserved meeting theme of the target meeting; perform a projection display based on the signal source to be displayed with the highest priority. Through the above technical solution, the relevance between each signal source to be displayed and the reserved meeting theme of the target meeting is determined according to the recognition results obtained from the image information, and then the priority is determined based on the relevance, and the signal source to be displayed with the highest priority is displayed. The entire process does not require manual selection and switching of the signal source, effectively improving the meeting projection efficiency and effectively reducing the impact of hardware failures on the meeting projection.

[0045] In some embodiments, the respectively recognizing each image information to obtain the recognition results of the signal sources to be displayed includes: using a preset convolutional neural network to respectively recognize each image information to obtain the recognition results of the signal sources to be displayed.

[0046] In this embodiment, the preset convolutional neural network can be understood as a neural network that has been pre-trained and is used to recognize image information.

[0047] Specifically, a pre-set Convolutional Neural Network (CNN) is used to identify the image information of each signal source to be displayed one by one. The CNN automatically extracts key features in the image information through its multi-layer convolutional structure, such as text, tables, charts, and graphics, and maps these features into high-level semantic information. Finally, the recognition results of each image are output. Through this solution, the image information can be quickly and accurately recognized, providing basic data support for further determining the signal source to be displayed with the highest priority.

[0048] Embodiment 2

[0049] Figure 2 FIG. is a flowchart of a conference projection method provided in Embodiment 2 of the present invention. This embodiment is optimized and extended based on the above-mentioned optional embodiments. Optionally, the determining the signal source to be displayed with the highest priority according to each recognition result includes: according to each recognition result, using the target priority rule, respectively calculating the first relevance between each signal source to be displayed and the reserved conference theme, where the target priority rule is a preset priority rule in a preset priority rule library determined according to the reserved conference theme of the target conference; determining the priority ranking of each signal source to be displayed according to each first relevance; and determining the signal source to be displayed with the highest priority according to the priority ranking. As Figure 2 shown, the method includes:

[0050] S210. Determine the image information corresponding to each signal source to be displayed among at least one signal source to be displayed of the target conference.

[0051] S220. Respectively identify each image information to obtain the recognition results of each signal source to be displayed

[0052] S230. According to each recognition result, use the target priority rule to respectively calculate the first relevance between each signal source to be displayed and the reserved conference theme, where the target priority rule is a preset priority rule in a preset priority rule library determined according to the reserved conference theme of the target conference.

[0053] In this embodiment, the first relevance is used to reflect the matching degree between the signal source to be displayed and the reserved meeting theme. The preset priority rule library can be understood as a pre-set rule set. Among them, the preset priority rule library includes preset priority rules and preset meeting themes, and different preset meeting themes correspond to different preset priority rules. The preset priority rule is used to determine the relevance between the signal source to be displayed and the preset meeting theme corresponding to the preset priority. For example, the preset priority rule can be to determine the relevance between the signal source to be displayed and the preset meeting theme corresponding to the preset priority by using the first matching algorithm based on the meeting process in the recognition result, or it can be to determine the relevance between the signal source to be displayed and the preset meeting theme corresponding to the preset priority by using the second matching algorithm based on the content information in the recognition result, etc. Among them, both the first matching algorithm and the second matching algorithm can be keyword matching algorithms or semantic similarity algorithms.

[0054] Specifically, according to the reserved meeting theme of the target meeting, determine the target priority rule corresponding to the reserved meeting theme from the preset priority rule library; for each recognition result in each recognition result, use the target priority rule to calculate the first relevance between the current signal source to be displayed and the reserved meeting theme.

[0055] Exemplarily, if the target priority rule is to determine the relevance between the signal source to be displayed and the preset meeting theme corresponding to the preset priority by using the first matching algorithm based on the meeting process in the recognition result, then according to the meeting process and the reserved meeting theme in the recognition result, use the first matching algorithm to calculate the first relevance between the signal source to be displayed and the reserved meeting theme; if the relevance between the signal source to be displayed and the preset meeting theme corresponding to the preset priority is determined by using the second matching algorithm based on the content information in the recognition result, then based on the content information and the reserved meeting theme in the recognition result, use the second matching algorithm to calculate the first relevance between the signal source to be displayed and the reserved meeting theme.

[0056] S240. Determine the priority ranking of the signal sources to be displayed according to the first relevances.

[0057] Specifically, perform priority ranking on the signal sources to be displayed according to the first relevances, where the higher the first relevance, the higher the corresponding priority.

[0058] S250. Determine the signal source to be displayed with the highest priority according to the priority ranking.

[0059] Specifically, determine the signal source to be displayed with the highest priority from the priority ranking.

[0060] S260. Perform projection display based on the signal source to be displayed with the highest priority.

[0061] The technical solution provided in the second embodiment of the present invention eliminates the need for manual selection and switching of signal sources, effectively improving the efficiency of conference projection and reducing the impact of hardware failures on conference projection. In addition, determining the signal source to be displayed with the highest priority based on each recognition result includes: according to each recognition result, using the target priority rule, calculating the first correlation degree between each signal source to be displayed and the reserved conference theme respectively, where the target priority rule is a preset priority rule in a preset priority rule library determined according to the reserved conference theme of the target conference; determining the priority ranking of each signal source to be displayed according to each first correlation degree; and determining the signal source to be displayed with the highest priority according to the priority ranking. It realizes calculating the correlation degree between the signal source to be displayed and the reserved conference theme using the target priority rule and sorting based on this correlation degree, further improving the accuracy and efficiency of determining the signal source to be displayed.

[0062] In some embodiments, the recognition result includes content information; determining the signal source to be displayed with the highest priority according to the priority ranking includes: if the difference between the first correlation degrees corresponding to the two signal sources to be displayed with the highest ranking in the priority ranking is less than a preset threshold, using a preset content prediction algorithm to perform content prediction respectively based on the content information of the two signal sources to be displayed with the highest ranking in the priority ranking, obtaining two predicted contents; calculating the second correlation degrees between the two predicted contents and the reserved conference theme respectively; and determining the signal source to be displayed with the highest priority according to the second correlation degrees.

[0063] In this embodiment, the preset threshold can be understood as a pre-set value. The preset content prediction algorithm can be understood as a pre-set algorithm for content prediction.

[0064] Specifically, when the difference between the first correlation degrees of the two signal sources to be displayed ranked first and second in the priority ranking is less than the preset threshold, it indicates that the correlations of these two signal sources with the reserved conference theme are relatively close, and it is difficult to directly distinguish their priorities through a single correlation index. To ensure the accuracy of determining the signal source to be displayed, a preset content prediction algorithm is used to analyze and predict the content information of these two signal sources to be displayed respectively, generating their respective predicted contents; furthermore, calculating the second correlation degrees between the two predicted contents and the reserved conference theme respectively, and determining the signal source to be displayed with the highest second correlation degree as the signal source to be displayed with the highest priority. This solution ensures that the signal source to be displayed that best fits the reserved conference theme is accurately selected when the correlations are close, thus significantly improving the accuracy and pertinence of conference information display.

[0065] In some embodiments, the target priority rule is determined as follows: obtaining the reserved meeting theme of the target meeting from the meeting reservation system; searching in the preset priority rule library for the preset meeting theme with the highest similarity to the reserved meeting theme; and taking the preset priority rule corresponding to the found preset meeting theme as the target priority rule.

[0066] In this embodiment, the meeting reservation system can be understood as a platform for arranging and managing meetings, where meeting reservations can be made.

[0067] Specifically, obtain the reserved meeting theme of the target meeting from the meeting reservation system. Then, by calculating the similarity between the reserved meeting theme and the preset meeting themes in the preset priority rule library, determine the preset meeting theme with the highest similarity to the reserved meeting theme in the preset priority rule library, and extract the corresponding preset priority rule as the target priority rule. This solution realizes the determination of the target priority rule and provides a key basis for further calculating the relevance between the signal source to be displayed and the meeting theme.

[0068] In some embodiments, the recognition result includes meeting process, content information, and participant information; the preset priority rule library at least includes the following preset priority rules: calculating a first correlation degree between the meeting process and the reserved meeting theme, a second correlation degree between the content information and the reserved meeting theme, and a third correlation degree between the participant information and the reserved meeting theme; and determining a first relevance between the signal source to be displayed and the reserved meeting theme according to the first correlation degree, the second correlation degree, and the third correlation degree.

[0069] In this embodiment, the participant information may include the position information of the participants. The first correlation degree is used to represent the matching degree between the meeting process and the reserved meeting theme, the second correlation degree is used to represent the matching degree between the content information and the reserved meeting theme, and the third correlation degree is used to represent the matching degree between the participant information and the reserved meeting theme.

[0070] Specifically, the preset priority rule library at least includes the following preset priority rules: calculating a first correlation degree between the meeting process and the reserved meeting theme, a second correlation degree between the content information and the reserved meeting theme, and a third correlation degree between the participant information and the reserved meeting theme; determining a first relevance degree between the signal source to be displayed and the reserved meeting theme based on the first correlation degree, the second correlation degree, and the third correlation degree. For example, the first correlation degree, the second correlation degree, and the third correlation degree can be weighted and summed, and the result of the weighted sum can be used as the first relevance degree between the signal source to be displayed and the reserved meeting theme, or the product of the first correlation degree, the second correlation degree, and the third correlation degree can be used as the first relevance degree between the signal source to be displayed and the reserved meeting theme.

[0071] Exemplarily, in a project seminar attended by multiple people, such as Figure 3 shown, there are three signal sources to be displayed connected to the projection device 20, namely the signal source to be displayed 21 corresponding to the project manager, the signal source to be displayed 22 corresponding to the chief technology officer, and the signal source to be displayed 23 corresponding to the account manager. Among them, the projection device 20 can only project the signal of one signal source to be displayed on the display 24 at a time.

[0072] The specific process of realizing projection: After the meeting is reserved, obtain the reserved meeting theme from the meeting reservation system, and then determine the target priority rule from the preset priority rule library. After the three signal sources to be displayed are connected to the projection device 20, perform content (such as text and charts, etc.) capture and recognition on the image information of the three connected signal sources to be displayed to obtain the recognition result. Furthermore, calculate the first relevance degree between the three signal sources to be displayed and the reserved meeting theme respectively in combination with the target priority rule, and perform priority sorting on the three signal sources to be displayed based on the first relevance degree; Assume that the signal source to be displayed 23 corresponding to the account manager ranks second, and the signal source to be displayed 21 corresponding to the project manager ranks first, but the difference between these two first relevance degrees is less than the preset threshold. Then, perform prediction based on the content information of these two signal sources to be displayed to obtain two predicted contents, and then calculate the second relevance degree between the two predicted contents and the reserved meeting theme respectively. At this time, the second relevance degree corresponding to the signal source to be displayed 23 of the account manager is relatively high, so the signal source to be displayed 23 of the account manager is projected onto the display 24.
