How to Create Digital Twins with Agisoft Metashape and IoT Sensors

Posted on by admin

Digital twins are virtual representations of real-world assets that mirror their physical counterparts in real-time using data from sensors, cameras, and other inputs. With Agisoft Metashape, you can create highly accurate 3D models from drone or terrestrial imagery, forming the visual foundation of a digital twin. When combined with IoT (Internet of Things) sensors, these models become dynamic, live-monitoring tools ideal for smart cities, asset tracking, industrial inspection, and more.

Why Combine Metashape with IoT?

While Metashape excels at building high-resolution, textured 3D models, these models are static. Adding IoT sensor data brings them to life by:

  • Tracking environmental conditions (temperature, humidity, air quality)
  • Monitoring structural integrity (strain, vibration, movement)
  • Enabling predictive maintenance for machinery or infrastructure
  • Creating live dashboards and interactive maps

This fusion is especially powerful for urban planning, industrial sites, energy grids, and smart buildings.

Step 1: Build the 3D Base in Metashape

Capture high-quality photos using drones or ground-based cameras. Ensure high overlap (80% front / 70% side) and proper lighting. Process the data in Metashape using the following workflow:

  • Align Photos
  • Build Dense Cloud
  • Generate Mesh (depth maps recommended)
  • Build Texture
  • Export model as OBJ, FBX, or Cesium 3D Tiles

You now have a detailed 3D asset to anchor your digital twin.

Step 2: Collect IoT Sensor Data

Install IoT sensors at key locations within your environment. These can include:

  • Temperature and humidity sensors
  • Vibration or tilt sensors (for bridges, towers, buildings)
  • Flow meters and power meters (for industrial monitoring)
  • GPS or UWB tags (for asset positioning)

Most sensors transmit data via Wi-Fi, LoRa, NB-IoT, or ZigBee to a local or cloud-based platform such as Azure IoT Hub, AWS IoT Core, or Node-RED.

Step 3: Map Sensor Data to 3D Models

Now it’s time to link real-world sensor data to your Metashape model. You can use platforms or APIs like:

  • Unity + IoT SDK: Import the 3D model and use C# to connect real-time data streams.
  • CesiumJS + WebSockets: Publish your model online and display sensor values as live overlays.
  • Blender + MQTT: For visualization prototypes or simulation workflows.

Each sensor corresponds to a virtual point in your model, allowing you to animate or color-code based on live values (e.g., heat maps or warning flags).

Step 4: Build a Live Dashboard or AR/VR Interface

With your 3D model and live data in sync, create interactive dashboards or immersive views for real-time monitoring. Tools you can use include:

  • Power BI or Grafana: Data dashboards embedded into digital twins
  • Unreal Engine or Unity: AR/VR interfaces for immersive monitoring
  • Web apps with Cesium or Three.js: Interactive browser-based views

This enables not only real-time observation, but historical trend tracking and future prediction through AI.

Use Cases by Industry

  • Smart Cities: Urban heat islands, pollution monitoring, traffic modeling
  • Industrial Plants: Asset tracking, temperature sensors, predictive failure
  • Construction: Progress monitoring, structural stability, safety zones
  • Environmental Monitoring: Flood prediction, erosion, water levels
