Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a decoration three-dimensional model rendering display method according to an embodiment of the present invention. As shown in fig. 1, the method includes:
The point cloud data acquisition equipment is used for acquiring original point cloud data of the house to be decorated, and can be laser camera equipment. And the point cloud data processing terminal acquires the original point cloud data of the house to be decorated from the point cloud data acquisition equipment. The point cloud data processing terminal can be a tablet computer, a PC (personal computer) and the like. The point cloud data acquisition equipment and the point cloud data processing terminal can transmit data in the modes of Bluetooth, Internet and the like.
And after the point cloud data processing terminal acquires the original point cloud data of the house to be decorated, adding mark point cloud data to the original point cloud data of the house to be decorated. The method comprises the steps of marking relevant information of positions which need to be obtained in the decoration process but cannot be identified by a cloud server when modeling is carried out according to original point cloud data of a house to be decorated, and marking the positions in advance, so that the preset special positions are obtained. For example, according to the needs of decoration design, the positions of a water outlet point, a flue, an air conditioner outlet, a heating device, a main pipeline and the like can be marked. When the preset special position is marked, marking is carried out according to the shape and the attribute of the target object at the preset special position, on one hand, marking is carried out according to the shape of the target object, for example, for a water outlet point, a point element or a surface element can be marked in point cloud data; for a main conduit, line elements or bin elements may be marked in the point cloud data. The marking according to the shape of the object can be realized by drawing a dot, a line, a picture, or the like in the dot cloud data. On the other hand, marking according to the attribute of the target object means that the attribute of the target object needs to be recorded, namely the target object is a water outlet point, a main pipeline, an air conditioner outlet and the like, so as to facilitate subsequent model construction and rendering.
And the point cloud data processing terminal marks the preset special position according to the shape and the attribute of the target object at the preset special position to obtain marked point cloud data. And the original point cloud data of the house to be decorated and the marked point cloud data jointly form point cloud data of the house to be decorated.
And the point cloud data processing terminal uploads the point cloud data of the house to be decorated to the cloud server. Because the point cloud data of the house to be decorated is usually very large, in order to improve the transmission rate, the point cloud data of the house to be decorated can be segmented and uploaded to the cloud server in blocks. The segmentation method of the point cloud data of the house to be decorated can adopt a chunk segmentation method. After receiving the point cloud data of the house to be decorated uploaded after the chunk segmentation, the cloud server merges all the point cloud data according to the ID number (chunkID) of the point cloud data after the chunk segmentation to obtain complete point cloud data of the house to be decorated.
102, after receiving the point cloud data of the house to be decorated, the cloud server generates three-dimensional model data of the house to be decorated according to the point cloud data of the house to be decorated; and the three-dimensional model data of the house to be decorated comprises the marked point cloud data.
And after receiving the point cloud data of the house to be decorated, the cloud server generates three-dimensional model data of the house to be decorated according to the point cloud data of the house to be decorated. And the three-dimensional model data of the house to be decorated comprises the marked point cloud data. The cloud server can generate three-dimensional model data of the house to be decorated according to the point cloud data of the house to be decorated by utilizing Visualization classes in the PCL point cloud library. When the Visualization type in the PCL point cloud library is used for generating the three-dimensional model data of the house to be decorated, the program can only identify the original point cloud data of the house to be decorated, and the three-dimensional model data corresponding to the original point cloud data of the house to be decorated is generated through identification and analysis of the original point cloud data of the house to be decorated. The generated three-dimensional model data can remove point cloud data irrelevant to the generated model, and only effective data is reserved. For example, the program may identify point cloud data of the wall surface, only important point cloud data (e.g., data of four corners) that can construct a wall surface model is required to be retained, and data in the middle of the wall surface may be removed.
When the Visualization type in the PCL point cloud library is used for generating the three-dimensional model data of the house to be decorated, the program can only identify the original point cloud data of the house to be decorated, and the marked point cloud data is important point cloud data to be reserved. Therefore, after the three-dimensional model data of the original point cloud data of the house to be decorated is generated by utilizing Visualization in the PCL point cloud library, the three-dimensional model data of the original point cloud data of the house to be decorated and the marked point cloud data form the point cloud data of the house to be decorated together, and the three-dimensional model data of the house to be decorated and the marked point cloud data are included.
And 103, downloading the three-dimensional model data of the house to be decorated from the cloud server by the house decoration design terminal, and rendering to generate the three-dimensional model of the house to be decorated.
After the three-dimensional model data of the house to be decorated is generated, if the coordinate form of the three-dimensional model data of the house to be decorated is not suitable for being displayed on a house decoration design terminal, coordinate transformation processing needs to be carried out on a cloud server at first.
And the house decoration design terminal downloads the three-dimensional model data of the house to be decorated from the cloud server and renders the data to generate the three-dimensional model of the house to be decorated. And the house decoration design terminal downloads the three-dimensional model data of the house to be decorated from the cloud server, and can automatically pull cdn upper file data by utilizing a designed loader. When the three-dimensional model of the house to be decorated is generated by rendering, the fields and the data of the three-dimensional model data of the house to be decorated are analyzed by using the designed loader, and then the three-dimensional model of the house to be decorated is generated by rendering by using the canvas tool drawing, so that model display is realized.
Js library implementation can be utilized by the loader. And when the loader is used for rendering according to the three-dimensional model data of the house to be decorated to generate the three-dimensional model of the house to be decorated, rendering the marked point cloud data is ensured.
Cdn relates to cloud data storage and data retrieval from the cloud. cdn is called a ContentDelivery Network, i.e., a content distribution Network. cdn is an intelligent virtual network built on the basis of the existing network, and by means of edge servers deployed in various places and through functional modules of load balancing, content distribution, scheduling and the like of a central platform, a user can obtain required content nearby, network congestion is reduced, and the access response speed and hit rate of the user are improved.
According to the embodiment of the invention, the point cloud data of the house to be decorated is obtained by adding the mark point cloud data to the original point cloud data of the house to be decorated, and the model rendering is carried out based on the three-dimensional model data of the house to be decorated including the mark point cloud data at the preset special position, so that the automatic generation of the decoration three-dimensional model required by decoration design is realized, the generation speed and the automation level of the decoration three-dimensional model are improved, the labor cost and the time cost are saved, the error of manual operation is avoided, and the precision of the decoration three-dimensional model is improved.
Further, based on the above embodiment, the marking of the point cloud data further includes marking, by the point cloud data processing terminal, the data missing position and the position not scanned by the point cloud data acquisition device to obtain the point cloud data.
The marked point cloud data comprises point cloud data obtained by marking a preset special position according to the shape and the attribute of a target object at the preset special position by the point cloud data processing terminal. The preset special position comprises at least one of a water outlet position, a flue position, an air conditioner outlet position, a heating position and a main pipeline position. The preset special position can also comprise a custom position item, for example, a position which cannot be identified by a program, such as a part structure protruding from a balcony, of a certain house can be marked.
The marked point cloud data also comprises point cloud data obtained by marking data missing positions and positions which are not scanned by the point cloud data acquisition equipment by the point cloud data processing terminal. During the process of collecting the point cloud data, the point cloud may be lost due to various reasons, for example, the light intensity is too large, and part of the point cloud data of the balcony may be lost. In the process of acquiring point cloud data, some areas may not be scanned due to the acquisition angle or the equipment, and therefore acquisition of corresponding position data is not achieved. Therefore, in order to ensure the comprehensiveness of the data, the positions where the data are missing and the positions which are not scanned by the point cloud data acquisition device can be marked. The marking method may also add a corresponding shape to the point cloud data according to the shape of the missing data area and the shape of the unscanned position, perform recording according to the data attribute at the corresponding position, and the like.
On the basis of the embodiment, the embodiment of the invention improves the comprehensiveness of the point cloud data by marking the data missing position and the position which is not scanned by the point cloud data acquisition equipment, thereby improving the integrity of the three-dimensional model of the house to be decorated.
Further, based on the above embodiment, after the cloud server receives the point cloud data of the house to be decorated, and before the three-dimensional model data of the house to be decorated is generated according to the point cloud data of the house to be decorated, the method further includes: and the cloud server performs filtering, denoising and data compression processing on the house point cloud data to be decorated, and keeps the marked point cloud data at the preset special position in the filtering, denoising and data compression processing process.
In order to remove unnecessary noise point cloud data in the house type and improve the data processing efficiency, after receiving the point cloud data of the house to be decorated, the cloud server firstly carries out filtering, denoising and data compression processing on the point cloud data of the house to be decorated, and then generates three-dimensional model data of the house to be decorated according to the point cloud data of the house to be decorated.
The filtering, denoising and data compression method can be realized by adopting a filtering algorithm and a compression algorithm expansion in a PCL point cloud library. Data compression can be achieved by diluting the data, i.e. it is also equivalent to removing a part of the point cloud data. In the filtering and denoising and data compression processing, the marked point cloud data at the preset special position cannot be removed. Therefore, in the filtering, denoising and data compression processing, the category of the point cloud data to be processed needs to be identified first, and if the point cloud data to be processed is marked point cloud data at a special position, the filtering, denoising and data compression processing is not performed. And if the point cloud data to be processed is the original point cloud data of the house to be decorated or other marked point cloud data, carrying out filtering, denoising and data compression processing.
The filtering and denoising can be implemented by firstly removing data obviously not belonging to the house interior through a regular filter, and then removing outliers and other noise data.
On the basis of the embodiment, the embodiment of the invention carries out filtering denoising and data compression processing on the point cloud data of the house to be decorated, and keeps the marked point cloud data at the preset special position in the filtering denoising and data compression processing processes, thereby improving the efficiency and the accuracy of generating the three-dimensional model of the house to be decorated, and ensuring the reliable generation of the three-dimensional model of the house to be decorated.
Further, based on the above embodiment, the size of the voxel selected by the cloud server in the filtering, denoising, and data compression processes is 0.1.
The embodiment of the invention finds that the voxel size selected in the filtering and denoising and data compression processing process is 0.1, so that the efficiency of the filtering and denoising and data compression processing can be improved.
Further, based on the above embodiment, after the three-dimensional model data of the house to be decorated is generated according to the point cloud data of the house to be decorated, before the house decoration design terminal downloads the three-dimensional model data of the house to be decorated from the cloud server, the method further includes: rendering and setting the visual attribute of the three-dimensional model data of the house to be decorated, and converting the three-dimensional model data of the house to be decorated into a display format of the house decoration design terminal.
After the three-dimensional model data of the house to be decorated is generated according to the point cloud data of the house to be decorated, the visual attributes of a point cloud data set formed by the three-dimensional model data of the house to be decorated, such as color, point size, opacity and the like, can be rendered and set. A method PCL in PCL point cloud library can be used for rendering and setting the visual attributes of the point cloud data set.
And the coordinate format of the point cloud data of the cloud server is not necessarily suitable for being displayed on a house decoration design terminal, so that coordinate transformation can be performed on the three-dimensional model data of the house to be decorated, and the three-dimensional model data can be converted into a format which can be displayed by the house decoration design terminal. Pcdtop multiplexer may be utilized to convert data into a custom data format for rendering by three. Js is a WebGL third party library written in JavaScript. A very large number of 3D display functions are provided. The house decoration design terminal can be developed and realized based on three.
On the basis of the embodiment, the embodiment of the invention ensures that the 3D rendering of the original house type is reliably realized at the house decoration design terminal by setting the visual attribute of the three-dimensional model data of the house to be decorated and converting the three-dimensional model data of the house to be decorated into the display format of the house decoration design terminal, thereby generating the three-dimensional model of the house to be decorated.
Further, based on the above embodiment, after the rendering generates the three-dimensional model of the house to be decorated, the method further includes: and the house decoration design terminal pulls the home model to the three-dimensional model of the house to be decorated, so that the updated three-dimensional model of the house to be decorated is obtained.
After the three-dimensional model of the house to be decorated is obtained, DIY design can be further carried out, and a home model (such as a furniture model, a household appliance model, a tile model and the like) is dragged into the three-dimensional model of the house to be decorated through the house decoration design terminal, so that the updated three-dimensional model of the house to be decorated is obtained.
On the basis of the embodiment, the display effect of the three-dimensional model of the house to be decorated is improved by dragging the home model to the three-dimensional model of the house to be decorated.
Further, according to the above embodiment, after the updated three-dimensional model of the house to be decorated, the method further includes: and the house decoration design terminal shares the three-dimensional model of the house to be decorated to a target client.
And after the updated three-dimensional model of the house to be decorated is obtained, the house decoration design terminal shares the three-dimensional model of the house to be decorated to a target client. If the three-dimensional model of the house to be decorated can be shared through WeChat, the decoration effect can be rapidly seen by the owner.
On the basis of the embodiment, the method and the system for building the house to be decorated share the three-dimensional model of the house to be decorated to the target client, so that rapidity and convenience of the target client for obtaining the three-dimensional model of the house to be decorated are improved.
Fig. 2 is a schematic flow chart of data processing in the decoration three-dimensional model rendering display method according to an embodiment of the present invention. Fig. 3 is a schematic process diagram of rendering and generating a three-dimensional model of a house to be decorated in the decoration three-dimensional model rendering and displaying method provided by the embodiment of the invention. The following further describes a flow of the decoration three-dimensional model rendering and displaying method provided by the embodiment of the invention with reference to fig. 2 and fig. 3.
Aiming at the prior art that the manual measuring room is displayed on a model, the process is long, and the following defects exist:
1. the labor cost and the expense cost are higher;
2. the precision is not controllable, and whether the subsequent construction is influenced or not is not influenced by the holding precision;
3. multiple roles are involved, including CAD designers, model designers;
4. takes too long time, with the duration of about 2 days
The technical scheme provided by the embodiment of the invention solves the four problems, and the scheme flow is as follows:
first, measuring room stage
The processing tasks and characteristics in the measuring room stage are as follows:
1. laser camera equipment (Point cloud data collector)
2. Treading point collection (generally, 100 square meters house needs to treading points about 20)
3. Splicing the data collected by each treading point
4. Marking special position data (toilet, kitchen water outlet point, etc.)
5. Save synchronization upload to cloud
The core processing data in the embodiment of the invention is point cloud data. The point cloud data is a massive point set which expresses the target space distribution and the target surface spectral characteristics under the same space reference system, is a model geometric description formed by a series of space sampling points on the surface of an object model, and is also a general expression form of three-dimensional laser scanning data. The formula is as follows:
pi ═ Xi, Yi, Zi, … … } represents a point in space; point Cloud ═ { P1, P2, P3, ….. Pn } represents a set of Point Cloud data.
The point cloud data contains rich information such as longitude and latitude coordinates, strength, multiple echoes, colors and the like of each point, and has relevant application in the fields of surveying and mapping, forestry, agriculture, digital cities and the like. However, the currently used lidar scanners, such as Riegl, Faro, Leica, etc., can generate thousands of points per second, the number of data points obtained by each scanning can reach hundreds of thousands and millions, and the data amount reaches dozens to hundreds of G. Of course, the larger the data, the higher the accuracy of the representation and the higher the price of the device. In the home decoration industry, the precision requirement also has a requirement, and a laser radar scanner with medium price can be selected. Some points are selected from one house type for collection.
In the acquisition process, positions and information which cannot be scanned by the equipment are marked, and a basis is provided for better displaying real model data subsequently. At this stage, information acquired by hardware needs to be automatically uploaded to a cloud server, self-research data segmentation is performed, and point cloud data uploading is achieved. And after the point cloud data processing terminal is stored, automatically uploading the original point cloud data and the marked point cloud data to the cloud.
The uploading design idea is as follows: the method comprises the steps that a point cloud data processing terminal (such as a tablet personal computer) obtains point cloud data (generally large) from hardware (point cloud data acquisition equipment, such as a laser camera), the point cloud data are subjected to chunk segmentation and then uploaded in blocks, the uploading state is monitored in the uploading process, and if uploading failure is found, a retransmission mechanism is triggered. After all the point cloud data are uploaded successfully, all the point cloud data are combined according to the block number (chunkID) to obtain complete point cloud data.
Second, data processing stage
The processing tasks and characteristics of the data processing stage are as follows:
1. denoising point cloud data (PCL point cloud filtering denoising)
2. Preserving special location data
3. Mass data compression process
In the data processing stage, filtering and denoising are realized based on the combination of a PCL point cloud base and a filtering algorithm, point cloud data compression is realized, and special position point data is reserved.
The flow of cloud server data processing is shown in fig. 2, and point cloud data obviously not belonging to a house may be removed by using a rule filter. Correcting part of the point cloud data, actually performing data compression, diluting original point cloud data through data compression, and reserving point cloud data (feature mark data) at a special position; a large amount of data can be compressed, pcl can be used, massive point clouds are compressed before being processed, and parameters such as the size (such as 0.1) of a proper voxel (voxel) can be selected in the processes such as feature extraction and the like, so that the algorithm efficiency is improved. outlier points are removed, points corresponding to outliers are outliers, also called outer points, namely points obviously deviating from the masses, for example, a flat wall is scanned by laser, point clouds which are almost on the same plane are normally obtained, but due to reasons such as equipment measurement errors, a small number of space points departing from the masses are generated, and the points are far away from the original wall, so that the points are called outliers. Class to remove outliers: stateticalOutlierRemoval, RaddiusOutlierRemoval, may be developed using these two classes. And removing noise, wherein other noise data in the point cloud data can be removed by applying a filtering algorithm.
During data processing, the required model data format (modified ply) is generated, which represents all the data of a model and is available for subsequent 3D model rendering. The data format is as follows:
third, model construction phase
The processing tasks and characteristics in the model construction phase are as follows:
1. PCL reads point cloud data and reproduces point cloud model based on Visualization
2. Incorporating marker positions into model data
3. Data format conversion (coordinate transformation)
After the model is built, the model data can be subjected to visual attribute rendering and setting, and the method for rendering and setting the visual attributes (color, point size, opacity and the like) of any point cloud data set is pcl, namely PointCloud < T > format; pcdtop multiplexer is provided to convert data into a custom data format for rendering by three.
The above processes are all cloud automatic processing for the client to automatically pull and render.
Four, house type 3D rendering stage
The processing tasks and characteristics of the house type 3D rendering stage are as follows:
1. js representation of ply model data
2. Reproducing for a particular position of a mark
