Description

Technical Field

[0001] The present invention relates to the field of control technology, and in particular to a method, device and equipment for controlling the displayed content of a teleprompter. Background Art

[0002] The teleprompter displays the contents of the manuscript through a display, and reflects the contents of the display on a special coated glass at a 45-degree angle in front of the camera lens, so that the speaker can face the camera while reading the speech. The host, the teleprompter and the camera are on the same axis, which creates a sense of intimacy that the speaker always faces the audience, and improves the quality of the speech. The existing teleprompter display method is to display the words on the display, and the size of the displayed content is achieved by adjusting the resolution of the display and the number of words displayed per line and the size of the font. The scrolling of the text is controlled by a wireless remote controller or a wired controller, such as acceleration and deceleration, play, stop, etc., which requires manual control. During the manual control process, when the depth distance between the speaker and the teleprompter changes, the console words cannot be well displayed within the best viewing angle of the eyes. When the depth distance between the speaker and the teleprompter is too small, the reading vision angle will increase when the width of the words displayed on the screen remains unchanged, so that the speaker's line of sight will move, giving people an uncomfortable feeling, and the picture taken by the camera will also be exposed; therefore, the existing teleprompter cannot intelligently adjust and automatically match the displayed content according to the current position of the speaker and the speaker's speech speed.

[0042] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a method for controlling content displayed by a teleprompter, comprising:

[0044] Step 11, obtaining a real-time distance parameter between the eyes of the first target object and the teleprompter screen;

[0045] Step 12, determining the opening angle of the eye of the first target object;

[0046] Step 13, determining adjustment parameters of the content displayed on the teleprompter screen according to the real-time distance parameter and the eye angle of the first target object;

[0047] Step 14: According to the adjustment parameters, the display content of the teleprompter screen is adjusted in real time to obtain the target content.

[0048] In this embodiment, the opening angle of the eyes of the first target object is the opening angle of the eyes of the first target object to the display content of the camera (audience) and the teleprompter screen (the display content of the camera and the teleprompter screen is always on a straight line, so the opening angles of the two are the same); step 11 can specifically be to identify the eye position of the first target object (speaker) in real time by a distance identifier set on the teleprompter screen, so as to determine the real-time distance parameter; the control method of the display content of the teleprompter is applied to the teleprompter system, and the display content of the teleprompter screen is adjusted in real time by the real-time distance parameter between the eyes of the first target object and the teleprompter screen, which effectively solves the problem that the existing teleprompter cannot intelligently adjust the display content of the teleprompter screen according to the current position of the first target object; it realizes the intelligent adjustment of the display content according to the current position of the first target object, and prevents the situation that the first target object, the teleprompter and the camera are not on the same axis because the display content of the teleprompter screen cannot be quickly adjusted due to the movement of the first target object before and after, thereby improving the quality of the speech.

[0049] In an optional embodiment of the present invention, step 12 may include:

[0050] Step 121, obtaining an initial width parameter of the content displayed on the teleprompter screen;

[0051] Step 122, determining an initial distance parameter between the first target object's eye and the teleprompter screen according to the initial width parameter;

[0052] Step 123, determining the movement range parameters of the eyes of the first target object;

[0053] Step 124: determining the eye angle of the first target object according to the initial distance parameter and the moving range parameter.

[0054] Among them, step 122 may include:

[0055] Obtaining vision parameters of the first target object; and determining an initial distance parameter between the eyes of the first target object and the teleprompter screen according to the vision parameters of the first target object and the initial width parameter.

[0056] In this embodiment, the initial width parameter of the content displayed on the teleprompter screen can be set according to the demand; step 122 can be specifically to determine the optimal position distance between the first target object and the teleprompter screen (at this distance, the first target object can clearly see the content displayed on the teleprompter screen), that is, the initial distance parameter, according to the first target object's vision degree and the initial width parameter; wherein, the first target object's vision degree can be measured and determined according to a vision test chart; for example, when the vision of the first target object measured by the vision test chart is 5.0, it means that when the content displayed on the teleprompter screen is 0.5 mm characters, the first target object can clearly see the content displayed on the teleprompter screen at a distance of five meters, and the initial distance parameter is 5 meters; in the specific implementation process, the width of the content displayed on the teleprompter screen can also be set to a fixed value, and then the first target object is moved until the first target object can clearly see the content displayed on the teleprompter screen, at this time, the distance parameter between the first target object and the teleprompter screen is measured, which is the initial distance parameter.

[0057] In an optional embodiment of the present invention, step 124 may include:

[0058] According to the formula Determine the eye opening angle ew of the first target object;

[0059] Among them, h is the initial distance parameter; θ is the moving range parameter, and its value range is 1 / 60 degree to 1 / 301 degree.

[0060] In an optional embodiment of the present invention, step 13 may include:

[0061] According to the real-time distance parameter and the eye angle of the first target object, an adjustment width parameter of the content displayed on the teleprompter screen is determined by a first preset formula.

[0062] Among them, the first preset formula is Among them, sw is the adjustment width parameter; ew is the opening angle of the eye of the first target object; H is the real-time distance parameter; er is the average radius of an adult's eyeball, which is 2.5 cm. The specific parameters are as follows Figure 2 As shown, Figure 2 Here, a represents the eyes of the first target object, and b represents the content of the teleprompter screen.

[0063] In an optional embodiment of the present invention, step 13 may further include:

[0064] Based on the adjustment width parameter, according to a preset magnification principle, an adjustment height parameter of the teleprompter screen display content is determined.

[0065] In this embodiment, the preset magnification principle can be set to proportional magnification. Specifically, the ratio of the initial height and initial width of the screen display content can be determined first, and then after the adjustment width parameter is determined, corresponding adjustments are made according to the ratio, thereby achieving proportional magnification of the teleprompter screen display content.

[0066] In an optional embodiment of the present invention, step 14 may include:

[0067] Step 141, obtaining voice data of a first target object;

[0068] Step 142, determining the current speech content and speech speed of the first target object according to the voice data;

[0069] Step 143, determining the scrolling parameters of the teleprompter display content according to the current speech content and speech speed;

[0070] Step 144, adjusting the display content of the teleprompter screen in real time according to the scrolling parameter and the adjustment parameter to obtain the target content.

[0071] In this embodiment, step 141 can specifically be to obtain the voice data of the first target object through the microphone, and can specifically use an audio processing library (such as pyaudio (audio library) or SpeechRecognition (speech recognition library) in Python) to capture the audio; step 142 can specifically be to convert the captured voice data into text, and can use a speech recognition API to achieve this; once the text content is obtained, the content of the current speech can be analyzed, and the speech speed can be determined by calculating the number of words per minute (WPM), or the speech speed can be estimated by timestamp or by analyzing the interval of the audio signal; step 143 can specifically be based on the speech speed and the current speech content, set The scrolling parameters of the teleprompter are determined; for example, if the speech speed is fast, the scrolling speed of the teleprompter should be increased accordingly; a formula can be used to calculate the scrolling speed, for example: scrolling speed = basic speed * (current WPM / preset WPM); the preset WPM) can be determined according to the average speaking speed of the first target object; step 144 can specifically be to pass the analysis result to the rendering engine to control the scrolling speed of the document and adjust the size of the displayed content, so as to determine the target content; front-end technology (such as JavaScript) can be used to achieve a dynamic scrolling effect of the document; during the speech, the speech speed and content can be continuously updated, and the scrolling parameters of the teleprompter can be adjusted in real time to ensure that the first target object can deliver the speech smoothly.

[0072] In this embodiment, the control method of the teleprompter display content solves the problem that the existing teleprompter cannot automatically match the display content according to the speech speed of the first target object through the design of the scrolling parameter. The automatic matching of the display content according to the speech speed of the first target object is achieved, and the speech quality is further improved.

[0073] The control method for displaying content on a teleprompter of the present invention solves the problem that the existing teleprompter cannot intelligently adjust and automatically match the display content and the font size of the display screen according to the current position of the first target object and the speech speed of the first target object. The intelligent adjustment and automatic matching of the display content according to the current position of the first target object and the speech speed of the first target object are realized, ensuring that the first target object, the teleprompter, and the camera are always on the same axis during the speech, thereby improving the quality of the speech.
