Detailed Implementation

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0012] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1 An optional process for generating a panoramic relationship diagram provided in an embodiment of the present invention. Figure 1 The following steps will provide a detailed explanation.

[0013] S101. Obtain the panoramic density of each sub-canvas in at least one sub-canvas corresponding to the canvas; the panoramic density is positively correlated with the number of panoramas in the sub-canvas and negatively correlated with the size of the sub-canvas.

[0014] In an embodiment of the present invention, the panoramic relationship diagram generation device obtains the panoramic density of at least one sub-canvas corresponding to the canvas; if the number of panoramas in the sub-canvas is greater and the size of the sub-canvas is smaller, then the panoramic density of the sub-canvas is greater.

[0015] In an embodiment of the invention, a source panorama and a target panorama of the roaming hotspot are set, along with information such as the hotspot title and icon. This roaming hotspot information is added to the roaming hotspot data, and the roaming hotspot is rendered at the center position of the current viewpoint of the panoramic roaming. Here, the current viewpoint refers to the viewpoint displayed by the panoramic roaming at this moment, and the roaming hotspot refers to an icon in a panoramic roaming where one can jump to other panoramas through the icon. Then, the panoramic relationship graph generation device divides the canvas according to the information contained in the roaming hotspot data and determines the panoramic position based on the panoramic density of the divided sub-canvases.

[0016] S102. Based on the sub-canvas with the lowest panoramic density, determine the rendering position of the current panorama to be added in the canvas, until multiple rendering positions corresponding to multiple panoramas to be added are obtained; the current panorama to be added is any one of the multiple panoramas to be added.

[0017] In an embodiment of the present invention, after the panoramic relationship diagram generation device obtains the panoramic density of each sub-canvas, it selects the sub-canvas with the lowest panoramic density, that is, the sub-canvas with the fewest panoramic views, and adds the current panoramic view to be added to the sub-canvas with the lowest panoramic density, until all panoramic views to be added are added to the canvas.

[0018] S103. Based on the jump relationship between multiple rendering positions and multiple panoramas to be added, render the panorama relationship diagram corresponding to multiple panoramas to be added in the canvas.

[0019] In an embodiment of the present invention, the panoramic relationship diagram generation device renders a panoramic relationship diagram corresponding to multiple panoramas to be added on the canvas based on the rendering positions of multiple panoramas to be added on the canvas and the jump relationships between them.

[0020] In an embodiment of the present invention, Figure 2 This invention provides a system for generating panoramic relationship maps based on point density. Figure 2It includes a data acquisition module, a panoramic relationship diagram initialization module, a roaming hotspot addition module, a node addition module, a connection module, and a save module. Among them, the data acquisition module is used to acquire roaming hotspot data, node data, and connection data; the panoramic relationship diagram initialization module initializes the relevant operation instructions of the relationship diagram canvas, and renders the corresponding nodes and connections in the canvas according to the node data and connection data to generate a panoramic relationship diagram; the roaming hotspot addition module is used to add roaming hotspots in the panoramic roaming, and the roaming hotspots can be dragged to adjust their positions in the panoramic roaming; the node addition module includes two methods: (1) according to the roaming hotspot data, the node position calculation method based on point density is used to calculate the position of the panoramic map node in the canvas, and render the corresponding node in the canvas; (2) respond to the node drag command and drag the panoramic view from the panoramic list to the canvas; the connection module is used to respond to the drag and draw line command to connect two nodes in the canvas; the save module is used to save the roaming hotspot data in the panoramic roaming, the node data and connection data of the panoramic relationship diagram in the canvas.

[0021] Understandably, in the embodiments of this invention, the panoramic density of the divided sub-canvases is compared, and the rendering position of the current panorama to be added is determined in the sub-canvas with the lowest panoramic density. Then, the division and panoramic density comparison are repeated until multiple rendering positions corresponding to multiple panoramas to be added are determined in the canvas. By generating a panoramic relationship graph through bidirectional linkage using a node position calculation method based on point density, the relationships between all panoramas can be presented intuitively and visually, greatly reducing the probability of duplicate or overlapping node positions in the panoramic relationship graph, and ensuring that nodes are evenly distributed across the canvas, thus improving the distribution effect between panoramas. Furthermore, the panoramic relationship graph can respond to operation commands such as canvas scaling / dragging, node dragging / deleting, dragging to draw lines, and deleting connections, providing batch and flexible operations for all panoramas.

[0022] In some embodiments of the present invention, S102 can be implemented by S1021, as will be explained in detail below.

[0023] S1021. When the panoramic density of the sub-canvas with the lowest panoramic density is equal to the panoramic density threshold, determine the rendering position of the current panoramic view to be added in the sub-canvas with the lowest panoramic density based on the height and width values ​​of the sub-canvas with the lowest panoramic density.

[0024] In some embodiments of the present invention, a panoramic density threshold is set. When the panoramic density in the sub-canvas with the lowest panoramic density is equal to the panoramic density threshold, the panoramic relationship graph generation device calculates the rendering position of the current panoramic view to be added in the sub-canvas with the lowest panoramic density based on the height and width values ​​of the sub-canvas with the lowest panoramic density.

[0025] In some embodiments of the present invention, the panoramic density threshold can be set to 0. If there is a sub-canvas 1 with the minimum panoramic density and a panoramic density of 0, it indicates that there is no panoramic node in the sub-canvas 1. The rendering position of the panoramic node to be added in the sub-canvas 1 is calculated based on the height and width values ​​of the sub-canvas 1. The rendering position of the current panoramic node is calculated based on the height, width, and reference coordinate values ​​of the sub-canvas 1 as shown in the following formula (1): (1) In formula (1), The width value of child canvas 1; The height value of child canvas 1; This indicates the current rendering location where the panorama will be added.

[0026] It is understood that in some embodiments of the present invention, the panoramic density corresponding to the sub-canvas with the lowest panoramic density is compared with the panoramic density threshold. When they are equal, it indicates that the sub-canvas with the lowest panoramic density does not have a panoramic view. In this case, a panoramic view is added to the sub-canvas with the lowest panoramic density, which reduces the probability of repeated or overlapping node positions in the panoramic relationship graph and ensures that the nodes are distributed more evenly in the canvas.

[0027] In some embodiments of the present invention Figure 3 An optional process for generating a panoramic relationship diagram provided in an embodiment of the present invention. Figure 2 S102 can also be implemented through S102-1 to S102-3, which will be explained in detail in conjunction with the following steps.

[0028] S102-1. When the panoramic density corresponding to the sub-canvas with the lowest panoramic density is greater than the panoramic density threshold, the sub-canvas with the lowest panoramic density is divided to obtain at least two new sub-canvases corresponding to the canvas.

[0029] In some embodiments of the present invention, when the panoramic density of the sub-canvas with the lowest panoramic density is greater than the set panoramic density threshold, the panoramic relationship graph generation device divides the sub-canvas with the lowest panoramic density to obtain two new sub-canvases.

[0030] In some embodiments of the present invention, the panoramic density threshold can be set to 0, the panoramic density of sub-canvas 1 is the minimum, and when the panoramic density of sub-canvas 1 is greater than 0, it indicates that a panoramic view has been added to sub-canvas 1. Therefore, sub-canvas 1 is divided to obtain at least two new sub-canvases.

[0031] S102-2, Obtain the new panoramic density for each new sub-canvas.

[0032] In some embodiments of the present invention, the apparatus for generating the panoramic relationship graph calculates the panoramic density corresponding to each new sub-canvas after division.

[0033] S102-3. Based on the new sub-canvas with the lowest new panoramic density, determine the rendering position of the current panorama to be added.

[0034] In some embodiments of the present invention, after the panoramic relationship graph generation device obtains the panoramic density corresponding to each new sub-canvas, it selects the new sub-canvas with the smallest panoramic density, compares the panoramic density of the new sub-canvas with the smallest panoramic density with the panoramic density threshold, and if it is equal to the panoramic density threshold, then the rendering position of the current panoramic to be added is determined in the new sub-canvas with the smallest panoramic density, and the determination method is as shown in formula (1). If it is greater than the panoramic density threshold, the new sub-canvas with the smallest panoramic density is divided again to obtain the re-divided sub-canvas, and the minimum panoramic density is judged again for the re-divided sub-canvas. This process is repeated until multiple rendering positions of multiple panoramic to be added in the canvas are obtained.

[0035] It is understood that in some embodiments of the present invention, if the panoramic density corresponding to the sub-canvas with the lowest panoramic density is greater than the panoramic density threshold, the sub-canvas with the lowest panoramic density is re-divided and iterated continuously, so that each time the panorama to be added is added to the sub-canvas with the lowest panoramic density where the number of panoramas is 0, the probability of repeated or overlapping node positions in the panoramic relationship graph is reduced, and the nodes are ensured to be distributed more evenly in the canvas.

[0036] In some embodiments of the present invention, S102-1 can be implemented by S201 to S202, which will be described in detail in conjunction with the following steps.

Based on height, width, and reference coordinates, divide the sub-canvas with the lowest panoramic density according to a preset division method to obtain at least two new sub-canvases corresponding to the canvas; the preset division method is used to divide the sub-canvas with the lowest panoramic density into equal parts.

[0040] In some embodiments of the present invention, the panoramic relationship diagram generation device divides the sub-canvas with the lowest panoramic density equally according to the obtained height, width and reference coordinates and a preset division method, to obtain at least two new sub-canvases corresponding to the canvas.

[0041] In some embodiments of the present invention, the sub-canvas with the lowest panoramic density can be divided into two, four, or nine equal parts, and the present invention does not impose any limitation. Taking four equal parts as an example, the center point of the sub-canvas with the lowest panoramic density is calculated based on the height, width, and reference coordinates of the sub-canvas with the lowest panoramic density. The specific calculation formula is shown in formula (2): (2) In formula (2), Center point; The x-coordinate value of the reference point; The ordinate value is the reference point.

[0048] In some embodiments of the present invention, a preset value is set, and the panoramic relationship diagram generation device reduces the obtained calculation results according to the preset value to obtain the area of ​​each new sub-canvas.

[0049] In some embodiments of the present invention, the area of ​​each new sub-canvas is calculated as shown in the following formula (3): (3) In the above formula, The area of ​​each new sub-canvas, .

[0050] S303, Get the number of panoramas in each new sub-canvas.

[0054] In some embodiments of the present invention, the new panoramic density of each new sub-canvas is calculated as shown in the following formula (4): (4) In the above formula (4), For the panoramic density of the sub-canvas, The number of panoramas in the child canvas. .

[0055] It is understood that, in some embodiments of the present invention, the area of ​​the multiple new sub-canvases after division is calculated using the height and width values ​​of the sub-canvas with the lowest panoramic density, and the panoramic density of the multiple new sub-canvases is obtained based on the area of ​​the multiple new sub-canvases and the number of panoramas they contain. The rendering position of the panorama to be added is determined based on the calculated panoramic density of the new sub-canvases, thus improving the accuracy of determining the rendering position of the panorama to be added.

[0056] In some embodiments of the present invention, S102 can also be implemented by S1021' to S1023, which will be described in conjunction with the following steps.

[0057] S1021' If the number of sub-canvases with the lowest panoramic density is greater than the preset value, then obtain the numbers of multiple sub-canvases with the lowest panoramic density.

[0058] In some embodiments of the present invention, after calculating the panoramic density of each sub-canvas, if the number of sub-canvas with the lowest panoramic density is greater than a preset value, the number carried by each sub-canvas with the lowest panoramic density is obtained.

[0063] S1023. Based on the target sub-canvas, determine the rendering position of the current panorama to be added in the canvas.

[0064] In some embodiments of the present invention, the panoramic relationship diagram generation device determines the rendering position of the current panorama to be added in the canvas based on the target sub-canvas.

[0066] S1031. Based on the coordinates of multiple panoramas to be added, determine the anchor point index values ​​of multiple panoramas to be added; the coordinates of the panoramas to be added correspond to the rendering positions of the panoramas to be added.

[0067] In some embodiments of the present invention, the panoramic relationship diagram generation device obtains the corresponding coordinates of multiple positions of the panoramas to be added in the canvas, and then compares the coordinates of the multiple panoramas to be added to determine the anchor point index values ​​of the multiple panoramas to be added.

[0068] In some embodiments of the present invention, an anchor point is a type of hyperlink in web page creation, also called a named anchor. Like a quick locator, it is a hyperlink within a page that can enable intra-page navigation or jump to a certain area of ​​another page.

Small circles indicate panorama anchor points, and numbers represent anchor point numbers. In two panoramas, if the index value of panorama one is 0 and the index value of panorama two is 2, then a line is created at the anchor point index 0 above panorama one and the anchor point index 2 below panorama two.

[0073] In some embodiments of the present invention, S401 to S402 are included before S1031, which will be described in detail in conjunction with the following steps.

[0074] S401: Display multiple panoramas and canvases to be added; In some embodiments of the present invention, the panoramic relationship diagram generation device displays the current canvas and multiple panoramas to be added in the canvas to the operator.

[0075] S402. In response to an operation specifying the location of the current panorama to be added, determine multiple rendering locations in the canvas corresponding to multiple panoramas to be added.

[0076] In some embodiments of the present invention, an operator drags a panorama to be added onto a canvas, and the panorama relationship diagram generation device responds to the operator's specified operation for the position of the current panorama to be added, and determines multiple rendering positions corresponding to multiple panoramas to be added in the canvas.

[0080] In some embodiments of the present invention, the operator sets a starting panorama and a target panorama among multiple panoramas to be added. Moving the mouse over the panorama activates it, displaying its border and anchor points at the center of the top, bottom, left, and right borders. Moving the mouse over an anchor point activates it; dragging the mouse creates a connection line, thus establishing a directed line from the starting panorama. Dragging the mouse to the anchor point of the target panorama on the canvas completes the connection creation, linking the starting and target panoramas. The panorama relationship diagram generation device responds to the operator's specified connection operation for the multiple panoramas to be added, creating corresponding connections between them on the canvas.

[0081] In some embodiments of the present invention Figure 6 This is a schematic diagram of the panoramic relationship effect provided in an embodiment of the present invention. The automatic generation of the panoramic relationship diagram in processes S101 to S103, or the drag-and-drop generation of the relationship diagram in processes S401 to S402 and S501 to S502, are both as shown. Figure 6 As shown, the panoramic relationship diagram generated based on the point density calculation method and bidirectional linkage can intuitively and visually present the relationships between all panoramas. Figure 6 It includes eight panoramas, all connected by directed lines. Taking panoramas 1, 4, and 6 as examples, panoramas 1 and 4 can be switched bidirectionally, but panoramas 6 cannot be switched back to panoramas 1.

[0082] In some embodiments of the present invention, the panoramic relationship diagram can respond to operation commands such as canvas scaling / drag, node dragging / deleting, dragging to draw lines, and deleting connections, providing batch and flexible operations for all panoramas. Specifically, when a canvas scaling command is received, the canvas is scaled with the mouse position as the center point, and the nodes and connections in the canvas are scaled synchronously; when a canvas drag command is received, the positions of the nodes and connections in the canvas are adjusted as a whole; when a node drag command is received, the position of the node in the canvas is adjusted, and the change in the node position does not affect the position of the connection to the anchor point; a delete button is displayed in the lower right corner of the node, and when a node delete command is received, the node and the node are deleted synchronously. Connecting lines and corresponding hotspots in the panoramic view; when the anchor point of a node is activated, it can respond to the drag-and-draw command, dragging the mouse to create a directed line starting from that node. Dragging the mouse to the anchor point of another node (target node) in the canvas stops the dragging, completing the creation of the line and simultaneously adding a hotspot in the panorama of the starting node; when a line is activated, it is highlighted and a delete button is displayed on the line. When a line deletion command is received, the line is deleted, and the hotspot in the panorama of the starting node of the line is deleted simultaneously; similarly, when a hotspot in the panoramic view is deleted, the corresponding line in the panoramic relationship diagram is deleted simultaneously.

[0083] S502. Based on multiple rendering locations and created connections, determine the panoramic relationship diagram between multiple panoramas to be added.

[0084] In some embodiments of the present invention, the panoramic relationship diagram generation device determines a panoramic relationship diagram between multiple panoramas to be added based on multiple rendering locations and created connections.

[0085] It is understood that in some embodiments of the present invention, any panorama can be manually dragged from the panorama list to the canvas, and the roaming jump relationship between two panoramas can be established by dragging and drawing lines. A custom panorama relationship diagram can be created, which effectively ensures the consistency between the roaming hotspots and the panorama relationship diagram in the panorama roaming, and can intuitively and visually present the relationship between all panoramas.

[0086] In some embodiments of the present invention, S1031 can be implemented by S601 to S604, which will be described in detail in conjunction with the following steps.

[0087] S601. Set the starting panorama and the target panorama among multiple panoramas to be added. The coordinates of the starting panorama include the first ordinate and the first abscissa; the coordinates of the target panorama include the second ordinate and the second abscissa.

The coordinates of the starting panoramic view are set as a first ordinate and a first abscissa, and the coordinates of the target panoramic view include a second ordinate and a second abscissa.

[0089] S602. When the first ordinate is less than the second ordinate, if the relationship between the first abscissa and the second abscissa satisfies the first preset condition, then the anchor point index of the starting panorama is the first preset value, and the anchor point index of the target panorama is the second preset value.

[0090] In some embodiments of the present invention, the first ordinate and the second ordinate are compared. When the first ordinate is less than the second ordinate, if the relationship between the first abscissa and the second abscissa satisfies the first preset condition, the anchor point index value of the starting panorama is the first preset value, and the anchor point index value of the target panorama is the second preset value.

[0091] In some embodiments of the present invention, the first preset value may be set to 1 and the second preset value may be set to 3, and the present invention does not impose any limitations.

[0092] In some embodiments of the present invention, the first preset condition is: the first abscissa is less than or equal to the second abscissa, and the difference between the first abscissa and the second abscissa is greater than the width of the starting panorama; or, the difference between the first ordinate and the second ordinate is less than the height of the starting panorama; the width of the starting panorama is equal to the width of the target panorama; and the height of the starting panorama is equal to the height of the target panorama. That is, when At that time, if and but anchor s =1、 anchor y =3.

This provides an intuitive and visual presentation of the relationships between all panoramas, reducing the probability of duplicate or overlapping node positions in the panoramic relationship diagram and ensuring that nodes are evenly distributed across the canvas. Furthermore, the panoramic relationship diagram can respond to operation commands such as canvas scaling / dragging, node dragging / deleting, dragging to draw lines, and deleting connected lines, providing batch and flexible operations for all panoramas.

When the anchor point is active (mouse hovers over the anchor point), dragging the mouse will create a connection line, thus creating a directed connection line with the node as the starting node. Dragging the mouse to the anchor point of another node (target node) in the canvas and stopping the dragging completes the creation of the connection line, connecting the two nodes, updating the panoramic relationship diagram, and adding the connection line information to the connection line data. Se, generate a panoramic relationship diagram.

[0142] Sf, Add roaming hotspots in panoramic roaming.

[0143] Add the roaming hotspot with the source panorama as the starting node and the target panorama as the target node to the roaming hotspot data, and render the roaming hotspot in the initial view of the panoramic roaming. The initial view refers to the position of the screen that is first seen when entering the panoramic roaming.

[0144] It is understood that, in some embodiments of the present invention, in the panorama list in the canvas, any panorama is dragged from the panorama list to the canvas, and then a line is created at the anchor points of multiple panoramas to connect the multiple panoramas and generate a panorama relationship diagram. Using this drag-and-drop method, the node positions in the canvas can be flexibly adjusted, and a clearer panorama relationship diagram layout can be customized to better reflect the relationship between nodes.
