Overview of 3D Modeling Services with UAV & Laser Scan

Terrestrial Laser Scanning (TLS)

Millimeter-level accuracy, ideal for modeling small details such as statues, architectural ornaments, interiors, or complex structures. The scanner captures millions of points per second, faithfully reproducing surface geometry and color.

RTK/PPK UAV

Covers areas from a few hectares to thousands of hectares in a short time, with accuracy down to a few centimeters. Aerial imagery is processed in Agisoft Metashape, Pix4D, ContextCapture to produce orthophotos, DEM/DTM, and overall 3D meshes/models.

Combining UAV & Laser Scan

• Millimeter-level detail for artifacts, architecture, and interiors.
• Centimeter-level accuracy for buildings, infrastructure, and large landscapes.
• Merged into a unified 3D model that is easy to share and leverage.

Why UAV & Laser Scan are a Breakthrough

From traditional to modern

Previously: manual measurements or traditional aerial photos — slow, costly, and fragmented data. Today: UAVs rapidly capture large areas; Laser Scan delivers ultra-high detail down to each ornament.

The combination creates multi-level, comprehensive 3D models — from incense burners just a few dozen centimeters tall to urban areas spanning several hundred hectares.

Benefits of Using UAV for 3D Modeling

• 3D data detailed to each centimeter for a clear understanding of current conditions.
• Accurate earthwork volume calculation for cost estimation.
• Transparent land boundary definition to reduce disputes.
• Support for design & planning, easy integration with CAD/BIM.
• Progress monitoring by comparing 3D models across project phases.
• Asset & infrastructure management with Digital Twin.
• Time & cost savings in surveying compared to traditional methods.

3D Modeling Workflow with UAV at 3DScan.vn

From survey to handover

• Step 1 – Intake & consulting: define objectives, scope, and technical standards.
• Step 2 – Flight planning: RTK UAV flight paths, altitude, overlap, and layout of GCP/BASE/CORS.
• Step 3 – Data acquisition: RTK UAV captures high-resolution imagery covering the entire area.
• Step 4 – Processing & modeling: Metashape/Pix4D/ContextCapture generate orthophotos, DEM/DTM, point clouds, and 3D meshes; GCP validation with errors < 3 cm.
• Step 5 – Handover: 2D (DWG, DXF, GeoTIFF), 3D (OBJ, FBX, E57), reports, and online viewer.

Typical turnaround: 2–7 days depending on location, area, and level of detail.

Levels of 3D Models with UAV

Detail level (small artifacts)

Incense burners, stone statues, triple-arched gates, etc. Low-altitude flights with ultra-high-resolution imagery produce crisp models down to each ornament.

Single-building level

Houses, factories, bell towers, bridges, etc. Accurately represents structure, materials, and colors, supporting design and preservation.

Complex / heritage / resort level

Pagodas/temples, schools, factories, small urban areas… Higher-altitude flights with broad coverage create overall models of landscape and infrastructure.

Large-area level (hundreds–thousands of hectares)

Mines, industrial parks, urban planning areas… RTK/PPK UAV fly large-area grids to generate DEM/DTM, orthophotos, and detailed 3D terrain models for planning and resource management.

Practical Applications of UAV 3D Models

• Construction & infrastructure: topographic surveys, progress monitoring, and as-built BIM checks.
• Planning & urban development: detailed 3D maps for smart city initiatives.
• Agriculture & forestry: crop monitoring, vegetation assessment, and forest management.
• Mining & industry: mine/stockpile volume calculation, exploitation monitoring, and yard management.
• Heritage conservation: detailed digitization of monuments for research, archiving, and restoration.
• Real estate & tourism: project promotion using 3D models and visual videos.
