In the construction industry's quickly changing world, it is no longer just an advantage to obtain the most accurate and efficient measurement—it has become a necessity. Traditional surveying techniques work well, but they can be cumbersome, time-consuming, labour-intensive, and they can be susceptible to human error. That is where drone and photogrammetry enter, a modern discipline that is revolutionizing the construction landscape by producing precise 3D models & measurements from simple pictures.
What is Photogrammetry?
Photogrammetry is a science that derives accurate measurements and 3D data through photographic means. Basically, photogrammetry involves imaging using multiple overlapping photographs of a site or structure, and then using computer software to obtain highly detailed computerized models, point clouds, topographical maps, etc. These models can be used as surveys, to record work accomplished, to verify quality, and in numerous other ways.
Significant Advantages of Drone Photogrammetry in Construction
Improved Precision
Photogrammetry enables construction professionals to obtain accurate measurements that often prove to be more precise than manually collected measurements. Photogrammetry uses high-resolution images, combined with comprehensive processing algorithms, to mitigate human error and produce consistent results. While this is advantageous for many types of construction measurement, it especially lends itself to:
As-built documentation: Ensuring that the design matches the actual construction.
Topographic surveys: Making accurate measurements of complex terrain.
Structural inspections: Monitoring for early detection of deformations or defects.
Improved Effectiveness
Conventional surveying can take days or even weeks to survey large construction sites. Photogrammetry reduces the time it takes to collect data to a matter of days:
Aerial drones can cover large areas quickly, usually within hours.
High-quality images and photogrammetry processing can return 3D models for immediate analysis.
Ongoing teams can monitor progress remotely, reducing the number of site visits needed.
Cost Savings
Photogrammetry effectively reduces the cost of the overall project by limiting the need for manual labor and the time to conduct the survey. Moreover, identifying issues early on prevents costly rework and delays.
Improved Collaboration and Documentation
3D models created from photogrammetry can easily be shared with stakeholders, architects, and engineers. This improves communication, aids Building Information Modelling (BIM) workflows, and enhances decision-making.
Safety Improvements
Safely surveying dangerous or difficult-to-reach locations is hazardous. Photogrammetry allows professionals to gather an accurate and precise amount of data at a distance, preventing unwanted accidents on site.
Use of Drone Photogrammetry in Construction
Site Surveys and Topographic Mapping: You can quickly create an accurate map to help with planning and design.
Volume Calculations: You can accurately measure the quantity of stockpiles, excavation sites, or materials.
Progress Tracking: You can monitor the construction process over time and compare it to the construction schedule.
Quality Control and Inspections: You can identify deviations, issues with structures, or misalignment.
Renovations and Restoration Projects: You can create an accurate record of existing structures in 3D.
Photogrammetry is innovating the construction industry by providing a single, powerful technology that is accurate, quick, and safe. Using photogrammetry on drone data will allow your business to be more efficient, save costs, and encourage collaboration, while getting accurate outcomes every time.
As construction becomes a more complex process, adding photogrammetry to your workflow is not just an option, but a necessity, in order to compete and deliver quality work.
