Description

Technical Field

[0001] The present invention relates to the technical field of dual-screen interaction, and in particular to an intelligently allocated dual-screen interaction method and terminal. Background Art

[0002] In general, computer users use a single display screen to observe the displayed information. Currently, 17-inch monitors are more popular and can meet the needs of general users. However, in some special occasions, such as when a large-scale on-site monitoring, CAD drawing, or application of electronic map technology are required, when a panoramic display is required, users have to require the computer to have a large enough display desktop so that the details of the scene can be seen more clearly and the operation is more convenient. In view of the above situation, even a 29-inch monitor has a very limited effective display size. At this time, split-screen display technology has to be used to solve the desktop size problem. Windows operating system supports this technology. Split-screen display here does not mean using a split-screen distributor to drive multiple monitors so that multiple screens display the same picture, just like the dynamic splitting effect in VC interface programming, but refers to installing multiple graphics cards with multiple monitors on a computer to achieve the purpose of doubling the size of the computer desktop.

[0003] Especially when drawing, staff need to enlarge the graphics when drawing details. When making some edits on the enlarged image, it is not convenient to clearly see the overall changes. Therefore, it is necessary to use dual-screen interaction technology to realize one screen for drawing details and the other screen for displaying the overall picture. However, when performing dual-screen interaction, the overall picture cannot adapt to the changes in details. It is necessary to constantly adjust the parameters of the screen corresponding to the overall picture, which affects work efficiency. In addition, it is not convenient to intuitively see the newly added content in the overall picture, resulting in inaccurate judgment when there are differences between the two screens. In view of this, we propose an intelligently allocated dual-screen interaction method and terminal. Summary of the invention

[0004] The purpose of the present invention is to provide a dual-screen interaction method and terminal with intelligent allocation to solve the problems raised in the above-mentioned background technology.

[0010] Preferably, in S1, the initial parameters of the display screen and the detail screen are the same, and adjusting the initial parameters includes adjusting the display size, brightness and contrast.

[0011] Preferably, the adjustment of initial parameters also includes an interface display algorithm, which is used to provide interface elements in the display screen and the detail screen respectively, so that the parameters adjusted by the user in real time are reflected on the display screen and the detail screen respectively, wherein the interface elements include a slide bar and an input box.

[0012] Preferably, the drawing program in S2 adopts computer graphics technology to convert the user's drawing operation into image drawing and editing through image display and drawing, user input response, image editing function, and zooming and adjusting function.

[0013] Preferably, the intelligent adjustment algorithm in S2 comprises the following steps:

[0014] S2.1, receiving the user's editing action through the drawing program on the detail screen;

[0015] S2.2, extracting features based on the features of the editing action to extract editing information, where the editing information includes the position, size, and color of the change;

[0016] S2.3, transmitting the edited information to the display screen to ensure normal communication between the two screens;

[0017] S2.4. After the display screen receives the editing information, a double buffering algorithm is used to convert the editing information into editing actions. The drawing program on the display screen is controlled in the background buffer to autonomously update the image, thereby completing the interactive synchronization of the two display screens. The autonomous operation includes drawing at the corresponding position, updating the image, and adjusting the image size and color.

[0018] Preferably, the marking of the newly added content in the display screen in S3 adopts a highlight marking algorithm, including the following steps:

[0019] Define a certain time interval as a time node, for example, every minute as a time node;

[0020] At each time node, compare the content of the current display screen with the content of the previous time node to detect the newly added content;

[0021] The image edge of the newly added content is detected through an edge detection algorithm, and the outline of the newly added content is marked, thereby achieving a highlight display effect.

[0022] Preferably, the comparison of the collected new content and the edited information features in S3 adopts an image difference comparison algorithm, including the following steps:

[0023] An image of the newly added content on the display screen and an image corresponding to the edited information on the detail screen are captured. The key points in the two images are detected using a key point detection algorithm, and a descriptor is generated to represent the features of each key point. By comparing the key points and descriptors of the two images, it is determined whether the image on the display screen is consistent with the image on the detail screen.

[0025] Matching degree = min(A1 / A2, A2 / A1)

[0026] Among them, A1 is the aspect ratio of the image corresponding to the editing information, A2 is the aspect ratio of the displayable area of ​​the display screen, if the matching threshold is set to a, if the matching degree ≥ a, a matching signal is output, if the matching degree < a, a non-matching signal is output.

[0027] Preferably, when receiving the mismatch signal, the automatic calculation of the parameter adjustment method and amount corresponding to the overall diagram in S4 includes the following steps:

[0028] Calculate the scaling ratio based on the size difference between the edited information and the display screen;

[0029] The number of pixels shifted is calculated based on the difference in image position between the edited information and the display screen.

[0030] The second object of the present invention is to provide a terminal for intelligently allocated dual-screen interaction, including the intelligently allocated dual-screen interaction method described in any one of the above, including two display screens, a transmission module, a processor, a memory, and a computer program stored on the memory and executable on the processor, wherein the two display screens are respectively used to display an overall image and edit and display a detailed image, the transmission module is used to realize the transmission and interaction of data between the two display screens, and the computer program, when executed by the processor, realizes the steps of the intelligently allocated dual-screen interaction method described in any one of the above.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention transmits the editing information on the detail screen to the display screen, and the display screen performs interactive synchronization according to the received editing information to ensure the content consistency of the two screens and realize information synchronization of the two screens, and then collects the newly added content and compares it with the editing information features. If the features are consistent, an interaction completion signal is output, and if the features are inconsistent, an abnormal interaction signal is output. This can not only determine whether the editing operation is consistent with the display effect and improve the accuracy of the interaction, but also mark the newly added content in the display screen, so that the newly added content can be displayed more intuitively and the observation effect is improved.

[0033] 2. After receiving the interaction completion signal, the present invention detects the adaptability of the editing information and the initial parameters of the display screen, automatically calculates the parameter adjustment method and amount corresponding to the overall picture, and adjusts it to the adaptive display screen of the overall picture. As the overall graphic is changed during the drawing process, the overall graphic will increase, and the initial parameters are not enough to fully display the overall picture. Therefore, when interactive synchronization is required, the method and amount of adjustment of the overall picture are calculated to ensure that the overall picture just fits the screen for display, which is conducive to maximizing the display of the overall picture.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0038] Computer users all use a single display screen to observe the displayed information. Currently, 17-inch displays are more popular and can meet the needs of general users. However, in some special occasions, such as when a large-scale on-site monitoring, CAD drawing, or application of electronic map technology are required, when a panoramic display is required, users have to require the computer to have a large enough display desktop so that the details of the scene can be seen more clearly and the operation is more convenient. In view of the above situation, even a 29-inch display has a very limited effective display size. At this time, split-screen display technology has to be used to solve the desktop size problem. Windows operating system supports this technology. Split-screen display here does not mean using a split-screen distributor to drive multiple displays so that multiple screens display the same picture, just like the dynamic splitting effect in VC interface programming, but refers to installing multiple graphics cards with multiple displays on a computer to achieve the purpose of doubling the size of the computer desktop.

[0039] like Figure 1-3 As shown, one of the purposes of the present invention is to provide a dual-screen interaction method with intelligent allocation, comprising the following steps:

[0040] S1. Define a display screen as a display screen and adjust the initial parameters for displaying the overall picture, and define another display screen as a detail screen and adjust the initial parameters for editing and displaying the detail picture. By adjusting the initial parameters of each screen, ensure that the display effects of the overall picture and the detail picture meet the requirements;

[0041] Specifically, since both display screens are blank when drawing at the beginning, when adjusting the initial parameters, the initial parameters of the display screen and the detail screen in S1 are made the same, and the adjustment of the initial parameters includes display size adjustment, brightness adjustment and contrast adjustment. As for, when adjusting the display size, an interpolation algorithm (such as bilinear interpolation and bicubic interpolation) can be used for image scaling processing, so that the image can be adjusted to the target size in proportion;

[0042] When adjusting the brightness, by linearly adjusting the brightness parameter, the following linear transformation formula can be used:

[0043] New pixel value = brightness parameter * original pixel value;

[0044] When adjusting the contrast, by linearly adjusting the contrast parameter, the following linear transformation formula can be used:

[0045] New pixel value = contrast parameter * (original pixel value - 0.5) + 0.5.

[0046] S2. Editing is performed on the detail screen through a drawing program, and the editing information is obtained according to the editing action using an intelligent adjustment algorithm, so that the display screen perceives the editing information for interactive synchronization. The editing information on the detail screen is transmitted to the display screen, and the display screen performs interactive synchronization according to the received editing information to ensure the consistency of the content of the two screens and realize information synchronization of the two screens;

[0047] Furthermore, the drawing program in S2 uses computer graphics technology to convert the user's drawing operation into image drawing and editing through image display and drawing, user input response, image editing function, and zooming and adjusting function. When the image is displayed and drawn, the drawing program can create a canvas on the screen by using computer graphics technology, and present the drawn graphics on the canvas in real time. This is achieved by creating an image buffer in the memory to represent the canvas, and then transferring the image data in the image buffer to the screen for display;

[0048] When responding to user input, the drawing program can receive various drawing operations of the user on the detail screen, such as clicking, dragging, zooming in, zooming out, etc. By monitoring the user's input events, the drawing program can determine the user's operation intention and convert it into corresponding image operations;

[0049] In the image editing function, the drawing program can provide various editing functions, such as line drawing, text insertion, graphic filling, color selection, shape transformation, etc. These functions can be realized through algorithms and formulas, such as Bresenham algorithm to draw lines, cubic spline interpolation algorithm to realize curve drawing, etc.

[0050] When scaling and adjusting, drawing programs usually provide image scaling and adjustment functions, allowing users to scale and adjust images on the detail screen as needed. This can be achieved by applying mathematical transformations and image processing algorithms, such as affine transformations, bilinear interpolation, etc.

[0051] Specifically, when editing a drawing on the detail screen, the editing information of the drawing needs to be synchronized to the display screen. Therefore, the intelligent adjustment algorithm in S2 includes the following steps:

[0052] S2.1, receiving the user's editing actions on the detail screen through the drawing program, such as clicking, dragging, zooming in, zooming out, etc.;

[0053] S2.2, extracting features based on the features of the editing action to extract editing information, where the editing information includes the position, size, and color of the change;

[0054] S2.3, transmitting the edited information to the display screen to ensure normal communication between the two screens, which can be done by using a network transmission protocol such as TCP / IP;

[0055] S2.4, after the display screen receives the editing information, the double buffering algorithm is used to convert the editing information into editing actions, and the drawing program on the display screen is controlled in the background buffer to autonomously operate and update the image, so as to complete the interactive synchronization of the two display screens. The autonomous operation includes drawing and updating the image at the corresponding position and adjusting the image size and color. Specifically, the working principle of the double buffering algorithm is as follows: a, create two image buffers, one for the foreground display and the other for the background operation;

[0056] b. After receiving the editing information, the display screen applies the editing information to the image in the background buffer to achieve autonomous operation and image update;

[0057] c. After the editing information is applied, the image in the back buffer is switched to the front buffer for smooth transition and display;

[0058] d. Continue to receive editing information and perform corresponding autonomous operations and image updates in the background buffer;

[0059] e. Repeat steps b, c, and d to achieve continuous interactive synchronization and image updates.

[0060] S3, preset a time node, mark the newly added content in the display screen within the time node, collect the newly added content and compare it with the editing information features, if the features are consistent, output an interaction completion signal, if the features are inconsistent, output an abnormal interaction signal, considering that there are differences in the editing information during the transmission process, if the differences cannot be discovered in time, it is easy to cause the contents displayed on the two display screens to be inconsistent. Therefore, through the above operation, not only can it be judged whether the editing operation is consistent with the display effect, and the accuracy of the interaction is improved, but also the newly added content in the display screen can be marked, and the newly added content can be displayed more intuitively, and the observation effect is improved;

[0061] It is worth noting that in order to mark the newly added content in the display screen, to capture the changes in the display screen within the time node, and to mark and process the changes, it is necessary to use a highlight marking algorithm for marking the newly added content in the display screen in S3, including the following steps:

[0062] Define a certain time interval as a time node, for example, every minute as a time node;

[0063] At each time node, compare the content of the current display screen with the content of the previous time node to detect the newly added content;

[0064] The image edge of the newly added content is detected through the edge detection algorithm, and the outline of the new content is marked to achieve a highlight display effect. Among them, the edge detection algorithm uses the Sobel algorithm, which is a gradient-based algorithm that can be used to detect edges in images. The Sobel operator is based on discrete difference sampling and calculates the gradient value by performing a convolution operation on the image to obtain edge information.

[0065] The comparison of the features of the newly added content and the edited information collected in S3 adopts an image difference comparison algorithm, including the following steps:

[0066] An image of the newly added content on the display screen and an image corresponding to the edited information on the detail screen are captured. The key points in the two images are detected using a key point detection algorithm, and a descriptor is generated to represent the features of each key point. By comparing the key points and descriptors of the two images, it is determined whether the image on the display screen is consistent with the image on the detail screen. The specific principle of the key point detection algorithm is as follows: key points are extracted through scale space extreme point detection and scale space extreme point screening, and the Gaussian difference pyramid can be used to locate the scale and position of the key points.

[0067] S4. After receiving the interaction completion signal, detect the adaptability of the editing information and the initial parameters of the display screen, automatically calculate the parameter adjustment method and amount corresponding to the overall picture, and adjust it to the overall picture adaptive display screen. As the overall picture is changed during the drawing process, it will cause the overall picture to increase, and the initial parameters are not enough to fully display the overall picture. Therefore, when interactive synchronization is required, calculate the method and amount of adjustment required for the overall picture to meet the requirements of the overall picture just fitting the screen for display, which is conducive to maximizing the display of the overall picture;

[0068] In addition, currently, when performing dual-screen interaction, the overall image cannot adapt to the changes in the adjustments on the details, and the parameters of the screen corresponding to the overall image need to be constantly adjusted, which affects the work efficiency. Therefore, during the interaction, the adaptability of the editing information and the initial parameters of the display screen should be detected so that the overall image can adapt to the screen and be fully displayed. The adaptability of the editing information and the initial parameters of the display screen in S4 is detected using a size matching degree evaluation algorithm. The size matching degree evaluation algorithm is used to calculate the matching degree between the size of the editing information and the size of the display screen. The algorithm formula is as follows:

[0069] Matching degree = min(A1 / A2, A2 / A1)

[0070] Among them, A1 is the aspect ratio of the image corresponding to the editing information, and A2 is the aspect ratio of the displayable area of ​​the display screen. If the matching threshold is set to a, if the matching degree is ≥a, a matching signal is output, and if the matching degree is <a, a non-matching signal is output. The aspect ratio of the editing information can be calculated by measuring the width and height of the editing information, and then the aspect ratios of the editing information and the display screen are compared to evaluate the degree of difference between the two. The aspect ratio refers to the proportional relationship between the width and height of the image. If the aspect ratio of the editing information is close to the aspect ratio of the display screen, they have a good match. The matching value is between 0 and 1. The closer the value is to 1, the closer the aspect ratio is, and the higher the matching degree is.

[0071] Then, when the mismatch signal is received, the automatic calculation of the parameter adjustment method and amount corresponding to the overall diagram in S4 includes the following steps:

[0072] Calculate the zoom ratio based on the size difference between the edited information and the display screen, using the formula: zoom ratio = display screen width / edited information width or zoom ratio = display screen height / edited information height;

[0073] The number of pixels to be translated is calculated based on the image position difference between the editing information and the display screen. The calculation formula is: number of pixels to be translated = target position - current position. The calculation is based on pixel units. The number of pixels to be translated is obtained by calculating the difference between the target position and the current position. The position of the editing information on the display screen may not match due to size differences or other factors. The number of pixels to be translated can be determined by calculating the difference.

[0074] In summary, the present invention improves the efficiency and accuracy of dual-screen interaction. Through the intelligent adjustment algorithm and interactive synchronization mechanism, it can realize the adaptive display of the overall picture by editing the detail picture, avoiding the tedious operation of constantly adjusting the parameters of the overall picture, and improving work efficiency. At the same time, by marking and comparing the features of the new content and the edited information, the new content can be displayed intuitively, and it can be judged whether there are differences between the two screens, reducing the inaccuracy of the judgment.

[0075] Furthermore, in order to realize that the specific values ​​of the parameters in the display screen and the detail screen can be intuitively determined when adjusting the parameters subsequently, the adjustment of the initial parameters also includes an interface display algorithm, and the interface display algorithm is used to provide interface elements in the display screen and the detail screen respectively, so that the parameters adjusted by the user in real time are reflected on the display screen and the detail screen respectively, wherein the interface elements include a slider and an input box; the position of the slider is mapped to the value range of the parameter, and the following linear mapping formula can be used:

[0076] Parameter value = minimum value + (maximum value - minimum value) * (slider position / slider length). You can intuitively see the status of each parameter change. The input box is convenient for users to enter the required parameters. When building a user interface with interface elements such as sliders and input boxes, you can follow the following steps: Create an interface layout for the display screen and detail screen, including interface elements such as sliders and input boxes, set an event handler for the slider to trigger parameter updates during the sliding process, and re-render the interface to achieve instant parameter feedback, then set an event handler for the input box to trigger parameter updates after the user enters the parameters, and re-render the interface, update the corresponding parameter values ​​according to specific needs and algorithms, and re-render the display screen and detail screen.

[0077] The second object of the present invention is to provide a terminal for intelligently allocated dual-screen interaction, including any one of the above-mentioned intelligently allocated dual-screen interaction methods, including two display screens, a transmission module, a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the two display screens are respectively used to display an overall view and edit and display a detailed view, the transmission module is used to realize the transmission and interaction of data between the two display screens, and the computer program is executed by the processor to realize the steps of the intelligently allocated dual-screen interaction method as described in any one of the above-mentioned methods;

[0078] Among them, the user can display graphics on the two display screens corresponding to the terminal device, one of which displays the detail image as the detail screen, and the other displays the overall image as the display screen, and realize the interactive synchronization of the operation tasks on the detail screen to the display screen through the transmission module. At the same time, the processor executes instructions on the interaction of the two display screens to complete the intelligent allocation of tasks, so that the user can efficiently handle different tasks on the two screens, ensuring that the user's operation on the dual-screen terminal is smooth and convenient;

[0079] Moreover, the memory can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic disk or optical disk, to store the tasks performed by the two display screens.
