Understanding Point Cloud Data

Point cloud data streamlines project workflows by providing professionals with large quantities of project site information. A point cloud is a collection of millions of data points organized within a three-dimensional configuration where each point represents a precise measurement of the specified space. Professionals can create and manipulate cohesive renderings for informed decision-making. The clouds also include RGB values, luminance values, dimensions and locations of objects and structures. Construction managers and architects rely on this information across numerous industries like construction, infrastructure, manufacturing and environmental science.

How We Transform Point Cloud Data into Detailed 3D Mesh Models

Professionals collect point cloud data using dependable data acquisition methods like 3D laser scanners and photogrammetry software, which have the power to generate high-quality digital models of trees, buildings, roadways, cars, statues and other small and large objects. Which process you choose will depend on your application, so consider how they aid in point cloud data collection:

  • Scanners: Send out light pulses to an object’s surface, measuring the time it takes each pulse to bounce back to the device to determine its position.
  • Photogrammetry: Leverage cameras and intelligent software to photograph an object at various locations to triangulate points and organize them into a 3D space.

Our Process For Point Cloud to Mesh Modeling

Point clouds are vital resources professionals rely on for visual documentation, inspections, engineering, retrofitting and other processes because they offer professionals a more efficient workflow, eliminating the need to return to the site repeatedly. However, these data sets can become large and cumbersome to work with, slowing the end-to-end process. Point clouds can be converted into digestible models, allowing managers to visualize complex information. These clouds can often become slow to load and cumbersome to digitally manipulate due to their size and the quantity of stored data, requiring conversion to user-friendly configurations.

Mesh modeling is a type of building information modeling (BIM) that allows stakeholders to view objects’ geometry with high density and high resolution. Point cloud to mesh conversions combine millions and millions of raw data points into a polygon mesh with vertices, faces, edges and polygons, such as triangles, while being lighter and easier to work with. These shapes and patterns store site characteristics, including location, intensity values, RGB information and other data. Mesh clouds are a valuable solution when dealing with fine details that may be difficult to reproduce within CAD software.

Collection of Raw Data Points

Gathering raw data points is the primary step to any successful point cloud to mesh conversion. As mentioned above, scanning and photogrammetry activities are two of the most popular strategies to collect this information. Scanning often leverages light detection and ranging (LiDAR) technologies to study project sites from the ground or in the air. These systems can take hundreds of thousands of pulses every second, capturing highly detailed data relating to an area that professionals can leverage to generate 3D mesh models.

Photogrammetry has existed for centuries, evolving into an effective strategy for learning more about your sites. This workflow relies on multiple cameras to take vertical or tilted pictures of a site from numerous angles. While taking pictures from above is the most popular strategy, professionals can use equipment like Total Stations to gather positional data from the surface. Images are then stitched together to gather measurements regarding features like surface levels, elevation and coordinates.

Preprocessing of the Data

When it comes to construction and surveying projects, accuracy is of the utmost importance. Data preprocessing is a valuable step in your point cloud conversion to transform raw information into a usable format. Regardless of the collection strategy you choose, the information you obtain will likely be misaligned, imperfect or inaccurate. Preprocessing is a crucial step encompassing modifying and improving your data’s condition to ensure its success.

Preprocessing consists of various steps to prepare your datasets for use by your team. One of the first steps is to clean your data, which involves removing noise and duplicates, filling in missing values, identifying outliers and aligning your data to create a cohesive and precise 3D model.

Model Generation

Once your data set meets your standards, you can use it to create your 3D model. Mesh generation uses this information to create a polygonal model complete with vertices, edges and faces. This model can take on almost every shape in unique sizes to meet your project’s requirements. This step usually involves a process known as a surface reconstruction, which fills in the gaps between data points to form a cohesive mesh. These models take shape using advanced algorithms, geometric designs, computational geometry and other processes. A few standard methods include:

  • Delaunay triangulation
  • Mapping mesh
  • Spatial decomposition
  • Quadtree mesh

Model Refinement

Post-processing is a crucial step to get the most out of your data. Refining your mesh model will help you prepare it for use and export, addressing concerns with gaps in data and distorted or jagged corners. This step also fills in any holes, smooths out edges and improves its appearance for high-quality, accurate results. Simplification is often used to refine models by decreasing the number of triangles used while keeping their proper shape. This step will reduce the file size and make it easier for professionals to process and utilize them on their tablets or phones. Other post-processing refinement and optimization strategies include:

  • Texturing
  • Edge flipping
  • Adaptive refinement

Benefits of Point Cloud to Mesh Modeling

Mesh models are highly realistic and detailed renderings of job sites used throughout various building and design applications. These solutions enable efficient rendering and manipulation of 3D objects for pre-job topographics, progress take-offs and as-builts. Mesh modeling offers countless advantages for professionals, including unrivaled accuracy and consistency when replicating real-world conditions that you can share throughout your team to foster collaboration, inform maintenance, improve management and develop growth strategies. Leverage mesh models to:

  • Enhance project visualization: Convert complex data into digestible and visually appealing models to streamline interpretation. Accurate models also optimize stakeholder collaboration to ensure everyone is on the same page.
  • Accelerate schedules: Engineers and architects receive an accurate picture of the site to increase their all-around performance for various procedures and tasks. Mesh modeling’s efficiency provides greater visibility, which allows project managers to identify potential roadblocks to avoid delays and keep projects on track.
  • Optimize decision-making: Professionals effortlessly extract meaningful data sets and countless numbers for an in-depth analysis of the entire project. These calculations gathered from mesh modeling facilitate strategic decision-making to understand potential challenges and make changes to prevent expensive alterations down the line.
  • Improve site safety: 3D mesh models enable project managers to evaluate relevant safety risks and create a viable solution. Precise job site models keep employees secure and reduce on-site hazards.
