[0109] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0110] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The descriptions used in this application and the appended claims, such as "a", "first", and "second", are not limitations on quantity or sequence, but are used to distinguish the same type of information from each other.

[0111] Before describing an embodiment of a method for constructing a flying line provided in the present application, first, the flying line is introduced. The flying line is a visualization method of data information on a large data screen, for example: a trajectory from a starting state to a target state, which can be a trajectory from a starting position to a target position. Conventional methods for drawing flying lines include: based on svg, canvas, webgl, etc.; among them, svg is a scalable vector graphics (Scalable Vector Graphics); Canvas is part of HTML5, allowing scripts to dynamically render bitmap images; webgl (full name Web Graphics Library) is a 3D drawing protocol, and the following introduces the shortcomings of the three drawing methods.

[0112] First of all, SVG and Canvas are both CPU-based drawing solutions, and their disadvantage is that the drawing performance drops sharply when drawing a large amount of data. This is because the SVG and Canvas drawing methods rely on the CPU to calculate the data required for the animation first, and then draw according to the calculated data. Since the browser is single-threaded, that is, it can only use the CPU for calculation or drawing tasks, when a large amount of data needs to be drawn, the browser is processing all the calculation tasks, and the drawing tasks cannot obtain computing resources, which causes the screen to freeze, and then causes the drawing performance to drop sharply.

[0113] Webgl's drawing method is based on GPU. All calculations and drawing are performed on the graphics card, which does not affect the browser's own calculation or drawing tasks. Therefore, the rendering of massive data will not be stuck. In the way of using Webgl to achieve flying line drawing, the conventional methods include line segment method, triangle face method, pipeline method, etc. The principle is to construct the vertices required for flying lines and then perform drawing processing. Among them, the line segment method is the easiest to implement. The disadvantage is that the native lines in the Webgl environment do not support width, and the visual effect is greatly limited; the triangle face method supports the flying line width by extending the vertex method through the line segment method, but the corner processing is complicated and jagged edges are prone to appear at small viewing angles; the pipeline method supports width and small viewing angle observation by extending the line segment into a pipeline method, but the number of vertex drawing is more than 10 times that of the line segment method, and jagged edges and defects are prone to appear when transparency is turned on.

[0114] Any of the above-mentioned flying line drawing methods has the problem of low drawing efficiency. Therefore, the present application provides a flying line construction method, which can improve the flying line drawing efficiency and avoid the occurrence of defects.

[0115] Please refer to Figure 2 As shown, Figure 2 1 is a flow chart of an embodiment of a method for constructing a flying line provided by the present application, the method comprising:

[0116] Step S201: Acquire data information describing the state change of an object.

[0117] Please combine Figure 2 refer to Figure 3 is shown, Figure 3 It is a structural schematic diagram of a flying line in an embodiment of a flying line construction method provided in the present application, wherein a flying line 301 is composed of particles 302, among which solid particles 3021 are visible particles, and hollow particles 3022 are invisible particles.

[0118] The object in step S201 can be any material that has data information or generates data information, which can be visible or invisible, for example: an object with a physical structure and a virtual object that does not have a real physical structure. Therefore, the purpose of step S201 is to obtain a data information that can express a state change, and it is not important who specifically generates the data information. Of course, the specific content of the data information can be reflected when drawing the flying line, because the main thing involved in the construction method of the flying line provided in the present application is the construction of the flying line, therefore, the focus is on obtaining data information with a state change.

[0119] In this embodiment, the data information describing the change of the state of the object may include at least the following data information:

[0120] Position information for describing the position of the object;

[0121] Time information used to describe the time corresponding to the position of the object.

[0122] Of course, it is understandable that the data information may also include some attribute information of the object, such as: name, type, purpose, etc.

[0123] After obtaining the data information of the object state change, it is necessary to generate particles representing the object state change, so step S202 is executed.

[0124] Step S202: Generate particles for representing the state change of the object according to the data information.

[0125] The purpose of step S202 is to obtain the elements constituting the flying line, that is, the flying line is constructed by particles. In the present embodiment, the particles in step S202 can be generated by a particle system. The particle system is used for the simulation of various fuzzy scenes in a computer, and it mainly solves the generation and display problems of a large substance composed of a large number of tiny substances moving (changing) according to certain rules on a computer. The phenomena that can be simulated usually include flames, explosions, smoke, water flow, sparks, fallen leaves, clouds, fog, snow, dust, meteor trails or abstract visual effects such as luminous tracks, etc., that is, a particle system can describe each element and the change of elements that make up an object.

[0126] The particle system consists of particles and emitters. Particles include properties such as shape, size, color, transparency, speed and direction of movement, life cycle, etc. In the particle system, the properties of particles are visualized through the particle object class (particle). Emitters are used to control the emission of generated particles.

[0127] Particle systems are usually divided into two types: point particles and quadrilateral particles. Point particles refer to particles that are all made up of points; quadrilateral particles map a particle texture onto a quadrilateral as a particle object. Since point particles can generate the next particle based on the properties of vertex particles without too much vertex information, in this embodiment, the flying line construction can be described in the form of point particles. Of course, it is understandable that the flying line shape that meets the requirements can be constructed by selecting the construction method of the particles.

[0128] Based on the above content, it can be known that the specific process of generating particles representing the state change of the object in step S202 may include:

[0129] Step S202-1: Determine the properties of the particles to be generated according to the data information.

[0130] In this embodiment, the properties of the particles to be generated may include at least one of the following properties:

[0131] Properties describing the shape of the particles to be generated;

[0132] Describe the properties of the position state change of the particles to be generated;

[0133] Attributes describing the time of state change of the particles to be generated;

[0134] Properties describing the size of the particles to be generated;

[0135] Attributes that describe the color of the particles to be generated.

[0136] The properties of the generated particles can be determined by data information according to the requirements of constructing the flying line. For example, the shape of the flying line can be determined by the shape properties of the particles, that is, the visual shape of the flying line can be determined by the properties of the particles.

[0137] Step S202-2: Determine the particle structure according to the properties of the particles to be generated.

[0138] In a particle system, the properties of particles determine the structure of the particles, so the step S202-2 can determine the particle structure according to the properties of the particles to be generated.

[0139] Based on the problem in the prior art that the width of the flying line is expanded by adding vertices, resulting in a decrease in drawing performance and efficiency, in this embodiment, only the radius of the particles needs to be adjusted through the particle system, that is, the flying line width can be adjusted without constructing multiple vertices, thereby avoiding the problem of decreased drawing performance and efficiency. Therefore, step S202-2 may include: based on the requirement of drawing the width of the object state change trajectory, according to the attributes describing the particle size, determining the particle radius, thereby completing the adjustment of the particle width.

[0140] This embodiment can not only complete the setting of particle width through the custom adjustment of particle radius set in the particle system, but also avoid the problem of partial or complete invisibility of flying lines or jaggedness in any viewing angle or scene. It should be noted that the invisibility here refers to the situation that the flying lines are invisible under the display requirement of visible flying lines, that is, the problem of failure to display normally.

[0141] Step S202-3: Generate particles for describing state changes in drawing the state change trajectory of the object according to the particle structure.

[0142] The purpose of step S202-3 is to determine the structure of the particles according to the determined particle properties, and then generate particles for drawing the state change trajectory of the object according to the particle structure. For example: the flying line is used to describe the motion trajectory of the pedestrian. Then, according to the time point of the pedestrian's movement, the particle of the pedestrian relative to the time point can be generated. The information of the time point is the particle attribute; different time points can correspond to different positions of the pedestrian. The above only takes the motion trajectory of the pedestrian as an example. Of course, the particle size attribute can also be set when generating particles, that is, the particles are generated according to the time attribute of the pedestrian and the preset particle size attribute. The generation of particles in this application can be implemented using an existing particle system, so the description is relatively concise.

[0143] After particles are generated according to the particle structure, each particle has attribute information. In this embodiment, the position attribute and time attribute of the particle are mainly used to describe the changing state of the particle, and the position attribute and time attribute can be determined by the acquired data information describing the change of the object state. Therefore, the generated particles will carry information of the position attribute and the time attribute.

[0144] After the particles used to represent the object state change are generated according to the data information of the object state change, flying lines used to describe the trajectory of the object state change can be generated according to the particles, as follows:

[0145] Step S203: generating a flying line for describing the trajectory of the object state change according to the particles within the preset position range.

[0146] The preset position range in step S203 may be determined according to display requirements, for example, the starting point and the ending point in the process of the object state change, and the starting point and the ending point may be regarded as vertices. A flying line may be a visual line describing the trajectory of the object state change, which may be understood as a line composed of multiple points of different or same shapes. The extension direction of the line may be regarded as the direction of the object state change. Therefore, step S203 may include:

[0147] Step S203-1: Determine the starting position and the ending position;

[0148] The starting position and the ending position in step S203-1 can be understood as the starting position and the ending position of the flying line, and the starting position can be determined according to the particle information at the starting position, and the ending position can be determined according to the particle information at the ending position. The determination method can be realized by following the time attribute of the particle, because the particle describes the information of the state change of the object, and the information of the state change of the object can include: the change information of the position state and the change information of the time state, and of course, the information of the shape change or the size change, etc. In this embodiment, the position and time change information are mainly used for explanation.

[0149] In other words, the step S203-1 can determine the particle information at the flying line vertex (starting point) and the particle information at the flying line ending point according to the change of time, for example: the position corresponding to the earliest object state change time is determined as the starting position, the earliest can be the earliest or minimum in the scope of describing the object state change, such as describing the time range of the object state change is 7:00-10:00 in the morning, then the position of the object state change corresponding to 7:00 can be determined as the starting position, 7:00 is the starting time; the position of the object state change corresponding to 10:00 is determined as the ending position, 10:00 is the ending time, and the flying line constructed according to this time range expresses the track of the object state change between 7:00 and 10:00. The generation of the flying line can be realized by step S203-2.

[0150] Step S203-2: according to the time attribute of the particle state change, the particles located between the starting position and the ending position are connected in sequence to obtain a flying line for describing the trajectory of the object state change.

[0151] The specific implementation of step S203-2 can be achieved by the emitter in the particle system. For example, according to the time attribute of the particle state change, the first particle at the initial position is determined, the emitter determines the first emitted particle, and then the second particle that is arranged after the initial position and adjacent to the first particle at the initial position is determined as the second emitted particle, and the process is carried out in sequence to obtain a flying line for describing the trajectory of the state change of the object. In other words, the particles can be connected in sequence by setting the emitter according to the time sequence of the particle state change to obtain a flying line for describing the trajectory of the state change of the object.

[0152] It is understandable that, for the generation of flying line, position information can be adopted to determine the particle of flying line starting position (vertex) and the particle of ending position, thereby generating flying line according to starting position and ending position. It is also possible to determine the time information of the particle of flying line starting position (vertex) and determine the time information of the particle of flying line ending position by adopting position information and time information, thereby generating flying line according to two elements of position and time. In the present embodiment, mainly adopt two elements of position and time to illustrate the process of generating flying line, in other embodiments, only position element can be adopted to generate flying line.

[0153] In this embodiment, the flying line is generated based on particles, and does not require a large amount of vertex information. It only needs to be generated according to the attribute information of the particles, thereby improving the construction performance. In addition, the construction of the flying line is completed based on the computing power of the GPU, that is, it is carried out in the graphics card, and has no effect on the calculation or drawing tasks of the browser itself. Therefore, it will not cause freezes in the rendering of massive data, thereby improving the efficiency of flying line construction or drawing in the environment of massive data.

[0154] In order to realize the dynamic display requirements of the flying line, reflect the different states of the flying line in different time ranges, and reflect the time relationship between each flying line, the flying line construction method provided by the present application may also include:

[0155] Step S204: Determine visibility information describing visibility of particles in the flying line according to display requirements of the flying line.

[0156] The purpose of step S204 is to realize personalized display of flying lines according to display requirements by controlling the visibility of particles. In an application scenario with multiple flying lines, the time relationship of each flying line, that is, the time relationship of data information, can also be reflected. Similarly, the visibility of particles can also reflect the different states of the flying lines, and the so-called different states can be the importance of the change of the state of the object.

[0157] Based on the above steps S201-S203, it can be known that the flying line construction process is achieved by connecting multiple particles in sequence according to the state change time attribute. Each particle can represent a state change of the object. In order to reflect the dynamic visual effect of the state change, the step S204 may include:

[0158] Step S204-1: Determine the display time requirement of the particles constituting the flying line.

[0159] The display time requirement for the particle in the described step S204-1 can be for the flying line, i.e., the display time requirement of the particle corresponding to the flying line area needs to be displayed, because the particle carries the time information of its own state change, therefore after determining the display time requirement, it is possible to determine the particle time information that matches with the display time requirement. Continue to use the above example, if the display time range of the flying line is 7:00-10:00, i.e., the display time is the flying line of the object state change track of 7:00-10:00, the particle display time requirement determined can be 7:00-8:30.

[0160] The specific implementation process of step S204-1 in this embodiment may include:

[0161] Step S204-1a: constructing a time mask according to the display requirements of the flying line;

[0162] For easier understanding, please refer to Figure 3 As shown, the time mask 303 can be regarded as a mask with time parameters, the mask covers the flying line area as a visible area, and the uncovered area is an invisible area; of course, it can also be understood that the mask covers the flying line area as an invisible area, and the uncovered area is a visible area.

[0163] Step S204 - 1b: Determine the display time requirement of the particles constituting the flying line according to the time mask.

[0164] The purpose of step S204-1b is to select particles whose time information meets the display time requirement from among the particles constituting the flying line. The time mask can control the visibility of the particles.

[0165] Step S204-2: displaying the particles whose time information meets the display time requirement in sequence according to the time attribute of the particle state change.

[0166] The purpose of step S204-2 is to display the particles that meet the display time requirement in the flying line. For example, when the display time range of the time mask is 7:00-8:30, the flying line part of 7:00-8:30 can be displayed within the flying line display time range of 7:00-10:00, that is, the particles with the display time requirement of 7:00-8:30 are displayed in sequence according to the time attribute of the particle state change, forming a flying line that describes the trajectory of the object state change.

[0167] In order to enable the flying line to be dynamically visualized, the step S204-2 may further include:

[0168] Step S204 - 2a: Determine the moving range of the time mask according to the particle display time requirement.

[0169] The moving range of the time mask in step S204-2a may be to adjust the start time and the end time of the time mask.

[0170] Step S204 - 2b: displaying the particles within the moving range of the time mask in sequence.

[0171] The specific implementation process of step S204-2b may be to continuously adjust or update the start time and the end time of the time mask, so as to filter out dynamically visible particles and form a dynamic visualization display of the flying line.

[0172] It should be noted that in this embodiment, the flying lines constructed can be set according to different display requirements. For example, if the requirement is to present a flying line within a certain time range between the starting position and the ending position of the flying line, the flying lines that meet the time mask can be displayed within the time range set by the time mask. By adjusting the start time and end time of the time mask, the flying lines can be displayed dynamically.

[0173] It is understandable that, in terms of the display effect of the flying lines, the transparency of the time mask can be set so that the flying lines within the time mask range can present display effects of different brightness.

[0174] Therefore, the time mask can be understood as a mask with time parameters. The area covered by the mask is the visible area, and the area not covered is the invisible area. Of course, it can also be understood as the area covered by the mask is the invisible area, and the area not covered is the visible area. By adjusting the transparency of the mask, the visible area is displayed in a gradient brightness state.

[0209] The above is a description of an embodiment of a flying line construction device provided in the present application. The description process is relatively brief. For specific contents, please refer to the description of an embodiment of a flying line construction method, and no further elaboration will be made here.

[0210] Based on the above content, this application also provides a method for displaying a flying line, please refer to Figure 5 As shown, Figure 5 1 is a flow chart of an embodiment of a method for displaying a flying line provided by the present application, the method comprising:

[0211] Step S501: Obtain flying lines for describing the state change of an object.

[0212] The flying line describing the state change of the object in step S501 includes a plurality of particles describing the state change of the object, such as Figure 6 As shown, each particle has a position attribute and a time attribute, and the position attribute of each particle is different, and the time attribute is also different. The particle at the starting position can be regarded as a vertex, and the vertex particles are connected in sequence according to the time requirement to form a flying line describing the change of the state of the object. The description of the above steps S201-S204 can be referred to for the flying line construction process, which will not be repeated here.

[0213] Step S502: Determine a visible area of ​​the flying line according to the display requirement of the flying line.

[0214] The purpose of step S502 is to highlight the flying line parts that need to be displayed and weaken the flying line parts that do not need to be displayed through the display requirements of the flying line. The display requirements of the flying line can be determined according to the importance of the data information or the display relationship of the data information. The specific implementation process may include:

[0215] Step S502-1: constructing a time mask according to the display requirements of the flying line;

[0216] Step S502-2: determining the area of ​​the flying line covered by the time mask as the visible area of ​​the flying line.

[0217] Furthermore, the visibility of the time mask, that is, the transparency, can be set to reflect the display degree of the flying line.

[0218] Based on the above content, the display of the flying line can display part of the area and hide part of the area according to different needs, which can display important data information and weaken the display of non-important data information.

[0219] Step S503: Displaying the determined flying line visible area on the terminal device.

[0220] According to the above-mentioned steps S501 and S502, the flying lines that need to be displayed can be displayed on the terminal device. In the present embodiment, the terminal device can be a large-screen data display device, and of course it can also be a PC device, etc.; it can also be a large-screen data display device and other terminal devices that display simultaneously. The simultaneous display can be to map the content of the large-screen data display device to the terminal device connected thereto. Of course, there can also be other display methods.

[0221] To realize the dynamic display of the flying line, reflecting the flying line in the spatial dimension and the time dimension, or reflecting the flying line in the time dimension, or the flying line in the spatial dimension, the step S503 may further include:

[0222] Step S503-1: determining the moving range of the time mask according to the display requirements of the flying line;

[0223] Step S503 - 2 : displaying the flying line areas within the moving range of the time mask in sequence.

[0224] For step S503-1 and step S503-2, please combine Figure 3 ,refer to Figure 6 As shown, Figure 6 It is a schematic diagram of the display effect of the flying line on the data screen in an embodiment of a flying line construction method provided by the present application. The moving range of the time mask can be adjusted according to the display requirements of the flying line, and the start time and end time of the time mask can be filtered out to form a dynamic visualization display of the flying line. For example: the display requirements of the flying line can be that the flying line starting position area part is emphasized, such as strong brightness, the brightness of the flying line middle position area part is second to the starting position area, and the brightness of the flying line end position area part is second to the flying line middle position area part. It can be achieved by adjusting the time range of the time mask and the transparency. Of course, if the flying line does not need to reflect the brightness, only the flying line part that needs to be displayed is reflected, then the transparency setting is not required.

[0225] The above is a detailed description of an embodiment of a method for displaying a flying line provided by the present application. Corresponding to the embodiment of a method for displaying a flying line provided above, the present application also discloses an embodiment of a display device for a flying line. Figure 7 Since the device embodiment is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment. The device embodiment described below is only illustrative.

[0236] The above is a description of an embodiment of a display device for a flying line provided in the present application. For specific contents, reference may be made to the description of an embodiment of a display method for a flying line.

[0237] Based on the above-mentioned flying line construction method and flying line display method, the present application also provides a flying line display method based on pedestrian travel trajectory.

[0238] Step S801: constructing a flying line describing the travel trajectory of pedestrians according to the flying line construction method described above;

[0239] The specific process of step S801 may refer to the description of steps S201 to S203 or steps S201 to S204 in the above-mentioned flying line construction method.

[0240] Step S802: Displaying the flying line on the terminal device.

[0241] The terminal device in step S802 may be a large-screen data display device, or other terminal device capable of displaying data information. The specific implementation process of this step may include:

[0244] The flying line of the pedestrian travel trajectory can also be realized by gradually displaying the amount of pedestrian travel data in a strong or weak manner. For example, when the number of pedestrians traveling is large, the flying line display can be enhanced by increasing the flying line brightness, increasing the flying line width, or changing the flying line shape, etc. When the number of pedestrians traveling is small, the flying line display can be weakened by dimming the flying line brightness, reducing the flying line width, changing the flying line shape, or changing the flying line color, etc. How to reflect the gradual display of strength and weakness is not limited by the above content.

It can be understood that for the flying line of the vehicle travel trajectory, the acquired data information is the data information of the vehicle travel state change.

[0249] Step S902: Displaying the flying line on the terminal device.

[0250] The specific implementation process of step S902 may include:

[0251] The flying line is displayed on the terminal device according to the location information and time information of the vehicle travel trajectory.

[0252] Furthermore, in order to reflect the dynamic display of the vehicle travel trajectory, the flying line can be gradually displayed in strength from the display starting position to the display ending position according to the requirements of the flying line display sequence.

[0253] The flying line of the vehicle travel trajectory can also be realized by gradually displaying the strength of the vehicle travel data volume. For example, when the number of vehicle trips is large, the flying line display can be enhanced by increasing the brightness of the flying line, increasing the width of the flying line, or changing the shape of the flying line. When the number of vehicle trips is small, the flying line display can be weakened by dimming the brightness of the flying line, reducing the width of the flying line, or changing the shape of the flying line or the color of the flying line. How to reflect the gradual display of strength and weakness is not limited by the above content.
