[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0048] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element.

[0049] The heatmap generation method provided in this application embodiment can be applied to, for example, Figure 1 The application environment shown includes at least terminal 101.
[0050] The terminal 101 is used to acquire operation instructions for the 3D heatmap, create a view plane based on the viewpoint information of the virtual camera, select target texture points from the texture points of the 3D heatmap, project the texture data bound to the target texture points onto the view plane, and generate a 2D heatmap based on the projected view plane. Furthermore, the terminal 101 can also install a configuration and / or viewing program for the heatmap to run and view the 2D and / or 3D heatmaps. The terminal 101 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, drones, IoT devices, and portable wearable devices. IoT devices can be smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.
[0051] In addition, the application environment may also include a server 102, which can be used to store the position coordinates, influence radius, and / or texture data of each texture point in the 3D heatmap, and send the position coordinates, influence radius, and / or texture data of each texture point to the terminal according to the instructions of the terminal 101. The server 102 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.
[0052] In one exemplary embodiment, such as Figure 2 As shown, a method for generating a heatmap is provided, which can be applied to... Figure 1 The following steps are used as an example of the terminal in the example, including steps 201 to 204.
[0053] Step 201: In response to the operation command for the three-dimensional heatmap, determine the viewpoint information of the virtual camera.
[0054] In this application, a heatmap is a graph used to characterize the distribution of data in a region. The density of data is usually represented by the intensity of color (chromaticity). For example, areas with darker colors (higher chromaticity) indicate higher data density, while areas with lighter colors indicate lower data density.
[0055] In practical applications, 3D heatmaps are also being used for three-dimensional scenes. A 3D heatmap is a map that uses the intensity (chromaticity) of colors to represent the density of data in a 3D modeling scene and / or a 3D map scene. For example, a heatmap corresponding to a city's top-down view can be used to observe the regional distribution of people in the city, while a heatmap corresponding to a city's front view can be used to observe the floor distribution of people in the city. 3D heatmaps include: 3D power heatmaps, 3D city heatmaps, 3D industrial heatmaps, and / or 3D pollution heatmaps; correspondingly, 2D heatmaps can also include 2D power heatmaps, 2D city heatmaps, 2D industrial heatmaps, and / or 2D pollution heatmaps.
[0056] This application retains the advantage of 3D heatmaps in viewing multi-dimensional data by converting the texture rendering of 3D heatmaps into the projection generation of 2D heatmaps. At the same time, it avoids the disadvantage of excessive consumption of computing resources caused by the need for texture rendering of 3D heatmaps every time the operator views them. This allows devices with lower computing power to view 3D heatmaps, thus improving computing power utilization.
[0057] In this context, a virtual camera refers to a software tool or technology used to simulate the behavior of a real-world camera, allowing users to observe and render 3D scenes from different perspectives. The virtual camera can be static or dynamic, representing the perspective of the operator and / or user. The viewpoint of the virtual camera refers to its position and orientation in 3D space, representing the perspective from which the operator and / or user ultimately observes the heatmap. Viewpoint information includes the virtual camera's line-of-sight coordinates and view vector. The line-of-sight coordinates represent the virtual camera's position in 3D space, and the view vector represents its orientation. Viewpoint information includes line-of-sight coordinates and / or view vectors.
[0058] During implementation, users and / or operators can view the 3D heatmap and manipulate it through rotation, translation, and / or scaling. This manipulation typically involves changing the viewpoint information of the virtual camera. Upon receiving the operation command, the terminal needs to redetermine the virtual camera's viewpoint information for rendering and displaying the heatmap. To address this, after receiving the externally input operation command for the 3D heatmap, the terminal first determines the virtual camera's viewpoint information. Responding to the operation command, it determines the virtual camera's viewpoint coordinates and view vector based on the operation parameters included in the command. These operation parameters can be the operation type (rotation, translation, and / or scaling) and operation data (rotation angle, translation distance, direction, and / or scaling ratio).
[0059] During execution, the terminal can determine the viewpoint information of the virtual camera based on the operation parameters contained in the operation instruction; the terminal can determine the calculation strategy based on the operation type contained in the operation instruction, and calculate the viewpoint information of the virtual camera after the operation based on the operation data and the original viewpoint information of the virtual camera before the operation instruction is received, according to the calculation strategy.
[0060] For example, when the operation type is translation, the calculation strategy is determined according to the translation type as follows: planar movement strategy. Based on the translation distance, translation direction and the original viewpoint coordinates in the original viewpoint information, the translated viewpoint coordinates are calculated. At the same time, the viewpoint coordinates are used as the starting point of the view vector, and the translated viewpoint coordinates and view vector are used as the viewpoint information of the virtual camera.
[0061] For example, when the operation type is rotation, the calculation strategy is determined according to the rotation type as follows: rotation-movement strategy, calculate the rotated viewpoint coordinates based on the rotation angle and the original viewpoint coordinates in the original viewpoint information, and use the viewpoint coordinates as the starting point of the view vector, and use the rotated viewpoint coordinates and view vector as the viewpoint information of the virtual camera.
[0062] Step 202: Create a view plane based on viewpoint information and preset distance parameters.
[0063] The view plane is an imaginary plane used by the virtual camera to generate 2D images. It is located a certain distance in front of the virtual camera and perpendicular to the camera's line of sight. The rendered content on the view plane is visible to the user and / or operator. This distance can be pre-configured using preset distance parameters; that is, the distance parameter represents the distance between the view plane and the virtual camera. Here, the normal vector of the view plane is parallel to the view vector, and the view vector of the virtual camera points to the center coordinates of the view plane. This distance parameter can also be dynamically adjusted in real time, and the user can control this distance parameter by adjusting the view.
[0064] This application converts the rendering of a three-dimensional heatmap into a projection of a two-dimensional heatmap, that is, projection is performed in the view plane. After the user and / or operator operates on the three-dimensional heatmap, the position of the view plane will also change, so the view plane needs to be recreated.
[0065] During implementation, the terminal obtains the preset distance parameters of the virtual camera relative to the view plane, determines the view plane information based on the distance parameters and the viewpoint information of the virtual camera, and creates the view plane based on the view plane information.
[0066] During execution, the terminal can create a view plane using the view vector and distance parameters in the viewpoint information. The terminal can obtain a vector pointing to the view plane by multiplying the view vector by the distance parameters, take the endpoint of the vector as the center coordinate of the view plane, and take the inverse vector as the normal vector of the view plane. The view plane is created based on the normal vector and the center coordinate. In addition, the terminal can create a target plane using the view vector as the normal vector and the viewpoint coordinates as the center coordinates, and translate the target plane along the direction of the view vector according to the preset distance parameters. The translated plane is then taken as the view plane.
[0067] For example, based on the position of the virtual camera and the normal vector N, a dynamic plane Plane is created that always faces the virtual camera and has the virtual camera lens as its center point. The normal vector N always faces the virtual camera. The plane can be represented as N(P-P0)=0, where P0 is the virtual machine position. The plane can eventually be displayed on a visualization screen for projection.
[0068] Step 203: Based on the position coordinates of each texture point in the 3D heat map, select the target texture point from the texture points. The position coordinates of the target texture point are within the view frustum of the virtual camera.
[0069] In practical applications, a 3D model (gray model) is usually created in a 3D heatmap. Texture data is bound to each point of the 3D model to render the texture data of that point on the surface of the 3D model. The points in the 3D model are called texture points. Texture points are used to define how each vertex on the surface of the 3D model is mapped to a 2D texture image. That is, they are used to wrap the 2D image (texture) on the surface of the 3D model so that the surface of the model can display patterns without adding extra geometric complexity.
[0070] The view frustum of a virtual camera refers to the area that a virtual camera can "see" when observing a scene in a 3D heatmap. It can be a planar area. The view frustum can be a perspective projection view frustum, in which the view frustum appears as a truncated pyramid, narrower closer to the camera and wider further away, simulating the effect of the human visual system or a real camera lens—the perspective effect of objects appearing larger when closer and smaller when farther away. The view frustum can also be an orthographic projection view frustum, in which case the view frustum is a cuboid, and all objects, regardless of their distance from the camera, are displayed at the same size, without any perspective scaling effect.
[0071] During implementation, the terminal selects the target texture points that the virtual camera can see from each texture point based on the position coordinates of each texture point in the 3D heat map and the viewpoint information and / or view plane information of the virtual camera; wherein the position coordinates of the target texture points are within the view frustum of the virtual camera.
[0072] During implementation, based on the two methods for creating view planes provided above, the vectors from each texture point to the view plane can be calculated, a target vector whose direction is opposite to the view vector of the virtual camera can be selected, and the texture point corresponding to the target vector can be selected as the target texture point. In addition, the vectors from each texture point to the target plane can be calculated, a target vector whose length is greater than a preset distance parameter can be selected, and the texture point corresponding to the target vector can be selected as the target texture point.
[0073] Step 204: Project the texture data bound to the target texture point onto the view plane based on the influence radius and / or position coordinates of the target texture point, and generate a two-dimensional heat map based on the projected view plane.
[0074] The influence radius of a texture point refers to the range of texture data that the texture point can project. The texture point only projects texture data within the influence radius. For example, if the influence radius of a texture point is x, then in the 3D model of the 3D heatmap, regardless of the original rendering size of the texture data of the texture point, the radius of the pattern rendered on the surface of the 3D model is fixed at x.
[0075] During implementation, the terminal acquires the texture data bound to the target texture point, projects the texture data onto the view plane according to the influence radius of the target texture point, and renders the projected view plane to obtain a two-dimensional heatmap, which is then displayed to the user and / or operator. Optionally, there can be multiple target texture points.
[0076] During execution, the terminal can sort the target texture points according to their distance from the view plane and project them according to the sorting results; or, it can determine the execution order of the projection process corresponding to the target texture point according to its distance from the view plane and execute the projection process of the target projection point according to the execution order.
[0077] It should be noted that the heat map generation method provided in this application can also be applied to a server. When applied to a server, the heat map can be a heat map for managing large areas, such as: power heat map, urban heat map and / or industrial heat map. The user and / or operator can be an administrator who submits operation instructions to the server through a terminal. After the server generates the two-dimensional heat map, it sends the generated two-dimensional heat map to the terminal for display. That is, the steps executed by the terminal in this embodiment can also be executed by the server. The server can refer to the execution process of the terminal when performing specific operations, which will not be described again hereafter.
[0078] In the above-mentioned method for generating heatmaps, in response to an operation command for a 3D heatmap, the viewpoint information of the virtual camera of the operator is determined. The viewpoint information includes viewpoint coordinates and view vector. A view plane is created based on the viewpoint information and preset distance parameters. The normal vector of the view plane is parallel to the view vector, and the view vector points to the center coordinates of the view plane. By creating the view plane, the rendering of the 3D heatmap is converted into the projection rendering of a 2D plane, which improves the rendering efficiency. Based on the position coordinates of each texture point in the 3D heatmap, target texture points whose position coordinates are within the view frustum of the virtual camera are selected from the texture points. Based on the influence radius and / or position coordinates of the target texture points, the texture data bound to the target texture points is projected onto the view plane, and a 2D heatmap is generated based on the projected view plane. By converting the rendering of a 3D model with high spatial and temporal complexity into the projection of a 2D plane to generate a heatmap, the demand for computing devices and / or computing resources is reduced, and the computing power utilization rate in the heatmap generation process is improved.
[0079] Based on the above exemplary embodiment, the following provides a method for generating a heatmap in one or more exemplary embodiments, which can be applied to... Figure 1 Taking the terminal in the example, the explanation includes the following content.
[0080] In practical applications, before operating on a 3D heatmap, that is, before the terminal receives the operation command, it can render and / or generate the 3D heatmap, or it can create a 3D heatmap according to the external input command. For the initial 3D heatmap, there is usually a default rendering position to be displayed to the operator of the 3D heatmap.
[0081] In the process of generating a 3D heatmap, rendering information of each texture point in the 3D heatmap can be obtained according to the rendering method of the 3D model. The 3D heatmap is then rendered based on this rendering information. Optionally, the rendering information includes position coordinates, influence radius, and / or texture data. In one optional implementation provided in this application, such as... Figure 3As shown, the process of generating a three-dimensional heatmap includes steps 301 to 302:
[0082] Step 301: In response to the command to view the 3D heatmap, obtain the position coordinates, influence radius and texture data of each texture point in the 3D heatmap.
[0083] During implementation, the terminal receives external input commands to generate and / or view a 3D heatmap, and in response to these commands, acquires the position coordinates, influence radius, and / or texture data of each texture point in the 3D heatmap.
[0084] For example, obtain a 3D texture point Point(x,y,z,w) with weight attributes, where (x,y,z) are spatial coordinates and w is the weight (default 1), which determines the radius of influence during rendering, representing the thermal influence range of the point; the projection of spherical textures onto the plane uniformly adopts circular plane projection, which is bound through the data acquisition stage and rendered on the view plane after the projection stage is completed.
[0085] Step 302: Render a 3D heatmap based on the position coordinates, influence radius, and texture data of each texture point.
[0086] During implementation, the terminal renders the texture data onto the surface of the 3D model in the 3D heatmap based on the position coordinates of each texture point and the texture data, according to the influence radius of each texture point, thus generating the 3D heatmap.
[0087] Furthermore, the rendering data of the 3D heatmap can be sent to the operator's terminal to display the 3D heatmap on the terminal.
[0088] It should be noted that a three-dimensional heatmap can also be created. That is, step 301 can be replaced by: in response to the command to generate the three-dimensional heatmap, creating multiple texture points, configuring the position coordinates and influence radius of each texture point, and binding the texture point with the corresponding texture data; during implementation, the terminal can receive external input commands to generate and / or view the three-dimensional heatmap, and in response to the command, create multiple texture points. For each texture point, according to the position coordinates, influence radius, and / or texture data contained in the command, configure the position coordinates and influence radius of the texture point, and bind the texture point with the corresponding texture data.
[0089] It should also be noted that steps 301 to 302 can be performed before step 201.
[0090] One optional implementation method provided in this application creates and renders a three-dimensional heat map through three-dimensional modeling, allowing the operator to view the three-dimensional heat map data. At the same time, a two-dimensional heat map is displayed to the operator through two-dimensional projection. This reduces the computational burden on the device while allowing the operator to view data in more dimensions, saves computing resources, and improves the rendering efficiency of the three-dimensional heat map.
[0091] During the creation of the view plane, the normal vector and center coordinates of the view plane can be determined using the viewpoint information of the virtual camera, and the view plane is created using the normal vector and center coordinates; in one optional implementation provided in this application, such as Figure 4 As shown, step 202 includes steps 401 to 403.
[0092] Step 401: Calculate the target vector based on the preset distance parameters and view vector.
[0093] The target vector is intermediate data used to determine the center coordinates of the view plane, and can be used to determine the center coordinates of the view plane and / or the normal vector of the view plane.
[0094] During implementation, the distance between the virtual camera and the view plane can be represented by a preset distance parameter. The terminal can multiply the distance parameter with the view vector to obtain the target vector, and the endpoint coordinates of the target vector are the center coordinates of the view plane.
[0095] Step 402: Use the endpoint coordinates of the target vector as the center coordinates of the view plane, and use the center coordinates as the starting point to create a normal vector.
[0096] During implementation, the terminal uses the endpoint coordinates of the target vector as the center coordinates of the view plane. Simultaneously, the view plane must always be parallel to the target plane where the virtual camera is located. Therefore, a vector opposite to the view vector and / or target vector can be created starting from the center coordinates, and this vector is used as the normal vector of the view plane. The direction of the normal vector is opposite to the direction of the view vector and / or target vector.
[0097] Step 403: Create the view plane based on the normal vector and center coordinates.
[0098] During implementation, the terminal can create a plane perpendicular to the normal vector and configure the center coordinates of the plane as the calculated center coordinates. This plane is used as the view plane. Furthermore, the area of the view plane can be configured by predicting its length and width, which can represent the area that the operator can view. The length and width of the view plane can be calculated by the view frustum and / or viewpoint parameters of the virtual camera.
[0099] One optional implementation provided in this application creates the view plane through vector computation, which improves the accuracy and reliability of the view plane. At the same time, vector computation avoids the use of complex algorithms and improves the rendering efficiency of the two-dimensional heatmap.
[0100] In the process of filtering target texture points, filtering can be performed by considering the direction of the projection vector of each target texture point onto the view plane, selecting texture points whose projection direction is opposite to the view vector as target texture points; in one optional implementation provided in this application, such as Figure 5 As shown, step 203 involves selecting the target texture point from each texture point based on its position coordinates in the three-dimensional heat map, including steps 501 to 502.
[0101] Step 501: Obtain the projection vector of each texture point to the view plane based on the position coordinates of each texture point.
[0102] During implementation, for each texture point, the terminal can use the texture point's position coordinates as the starting point and calculate the projection vector with the endpoint in the view plane and perpendicular to the view plane. This projection vector is used to characterize the projection distance and projection direction of each texture point from the view plane.
[0103] Step 502: Select the target projection vector whose direction is opposite to the view vector from each projection vector, and take the texture point corresponding to the target projection vector as the target texture point.
[0104] During implementation, the terminal filters out the target projection vector that is opposite to the view vector based on the direction of each projection vector. That is, it filters out the target projection vector that is opposite to the view direction of the operator, and uses the texture point corresponding to the target projection vector as the target texture point to filter out the texture points that can be viewed by the operator.
[0105] One optional implementation provided in this application filters texture points by filtering the projection vectors of texture points onto the view plane. Vector operations improve data processing efficiency, thereby improving the rendering efficiency of the two-dimensional heatmap. At the same time, vector calculations also improve the accuracy of the filtering results.
[0106] During projection, models closer to the virtual camera in the 3D heatmap may obscure the textures of distant models, preventing the virtual camera (operator) from viewing the textures of the distant models. To address this, target texture points can be sorted according to their distance from the view plane, and the projection order can be determined based on the sorting result. Projection is then performed sequentially based on the influence radius, position coordinates, and / or texture data of the target texture points according to this projection order. In one optional implementation provided by this application, such as... Figure 6 As shown, step 204 includes steps 601 to 602:
[0107] Step 601: Sort the target texture points based on the length of the target projection vector corresponding to each target texture point to obtain the sorting result.
[0108] The number of target texture points is multiple; the sorting priority of each target texture point is positively correlated with the length of the target projection vector corresponding to each target texture point.
[0109] During implementation, the terminal first sorts the target texture points in descending order based on the length of the target projection vectors corresponding to each target texture point to obtain the sorting result; here, the sorting result is the projection order.
[0110] For example, calculate the position and distance of the target texture point projected onto the view plane, and sort them from farthest to closest according to the distance. At the same time, based on the direction of the target projection vector, exclude texture points located behind the virtual camera. That is, the target projection vector of the target texture point onto the view plane should be consistent with the direction of the normal vector of the view plane.
[0111] Step 602: According to the sorting results, the texture data bound to each target texture point is projected onto the view plane in sequence based on the influence radius and / or position coordinates of each target texture point.
[0112] During implementation, the terminal uses the sorting result as the projection order. First, it projects the texture points that appear earlier in the sorting result. For any target texture point, the texture data bound to the target texture point is projected onto the view plane according to the influence radius and / or position coordinates of the target texture point. This texture can cover the texture of the target texture point that was projected earlier, or it can be covered by the texture of the target texture point that was projected later. The light in the projection process is parallel light, that is, the projection light of the cylinder is constructed according to the influence radius.
[0113] For example, texture points are projected onto the view plane to generate a 2D heatmap. Projected points are added sequentially according to the order of the sorting stages. Each time a projected point is added, a cylindrical structure with a radius of w and an endpoint at the view plane is added.
[0114] One optional implementation provided in this application simulates the perspective projection relationship in a three-dimensional heatmap by sorting and projecting the target texture points. It simulates a three-dimensional perspective view by using two-dimensional projection, which saves computing resources and improves the rendering efficiency of the heatmap while retaining the data of the three-dimensional heatmap. At the same time, the sorted projection method avoids errors in perspective relationship and improves the accuracy of the two-dimensional heatmap.
[0115] In practical applications, heat maps can be used to view power load in power scenarios, to view pedestrian and / or vehicle traffic in urban management scenarios, and to view pollution levels in environmental scenarios; one optional implementation provided in this application is as follows: Figure 7As shown, it also includes steps 701 to 702.
[0116] Step 701: Determine the power load of each region based on the thermal colorimetry of each region in the two-dimensional heat map.
[0117] In practical applications, heat maps represent the distribution of data by the color intensity of heat in a region. Generally, the higher the color intensity, the denser the data. Electricity load is positively correlated with thermal color intensity.
[0118] During implementation, the terminal performs image recognition on the two-dimensional heat map and determines the data density of each area based on the thermal color of each area in the heat map, i.e., the power load status.
[0119] Step 702: Determine the power control strategy based on the power load situation.
[0120] During implementation, the terminal can determine the power control strategy based on the power load of each region. It can generate strategies to allocate power from regions with low power load to regions with high power load, or it can generate strategies to increase the power output to regions with high power load.
[0121] Furthermore, the power control strategy can be sent to the operator's terminal so that the operator can submit power control instructions according to the power control strategy, or, with authorization, directly carry out power control according to the power control strategy.
[0122] For example, such as Figure 8 As shown, the power in the blue area can be redirected to the red area.
[0123] One optional implementation provided in this application applies heat maps to power scenarios, uses two-dimensional heat maps to represent power load conditions, and uses the color of the two-dimensional heat map to determine the power load conditions of a region, thereby improving the timeliness of power regulation. At the same time, the method of using heat maps to represent power load conditions enhances the perception of power management parties, and the use of image processing avoids the need for devices to process complex power data, thereby improving the efficiency of generating power regulation strategies.
[0124] In one embodiment, see Figure 9 It illustrates a flowchart of a method for generating a heat map according to an embodiment of this application, which can be applied to... Figure 1 In the terminal shown. For example... Figure 9 As shown, the method for generating this heatmap may include the following steps:
[0125] Step 901: In response to the command to generate a 3D heatmap, obtain the position coordinates and influence radius of multiple texture points, and obtain the corresponding texture data bound to the multiple texture points.
[0126] Step 902: Render a 3D heatmap based on the position coordinates, influence radius, and texture data of each texture point.
[0127] Step 903: In response to the operation command for the three-dimensional heatmap, determine the viewpoint information of the virtual camera.
[0128] Step 904: Calculate the target vector based on the preset distance parameters and view vector, use the endpoint coordinates of the target vector as the center coordinates of the view plane, and use the center coordinates as the starting point to create a normal vector.
[0129] Step 905: Create the view plane based on the normal vector and center coordinates.
[0130] Step 906: Obtain the projection vector of each texture point to the view plane based on the position coordinates of each texture point.
[0131] Step 907: Select the target projection vector whose direction is opposite to the view vector from each projection vector, and take the texture point corresponding to the target projection vector as the target texture point.
[0132] Step 908: Sort the target texture points based on the length of the target projection vector corresponding to each target texture point to obtain the sorting result.
[0133] Step 909: According to the sorting results, project the texture data bound to each target texture point onto the view plane in turn based on the influence radius of each target texture point.
[0134] Step 910: Determine the power load of each region based on the thermal colorimetry of each region in the two-dimensional heat map, and determine the power control strategy based on the power load.
