A Modern Solution for 3D Digital Twin and Augmented Reality

A city utility worker needs to locate buried assets accurately and efficiently.

Bad Elf Flex Extreme GNSS

The Bad Elf Flex Extreme is a high-performance GNSS receiver designed for GIS, mapping, and surveying applications. Key Features:

• Multi-Constellation Support: Compatible with GPS, GLONASS, BeiDou, Galileo, and QZSS.

• High Accuracy: Achieves centimeter-level accuracy with RTK corrections.

• Versatility: Works seamlessly with iOS, Android, and Windows devices.

Pix4Dcatch

Pix4Dcatch is a mobile application that transforms your device into a professional 3D scanner, enabling the capture of accurate 3D models and maps. Key Features:

• Real-Time 3D Capture: Provides live feedback during data collection.

• Augmented Reality (AR) Visualization: Overlays georeferenced 3D models onto the real world for immediate analysis.

• RTK Compatibility: Supports integration with RTK devices like the Bad Elf Flex for enhanced accuracy.

The Field Operation

Equipped with the Bad Elf Flex Extreme GNSS receiver and the Pix4Dcatch app on a tablet, the utility worker embarks on the task.

1. Setup: The worker pairs the Bad Elf Flex Extreme with the tablet via Bluetooth, ensuring a stable connection.

2. RTK Initialization: Connecting the Bad Elf Flex app to an RTK network provides real-time corrections, enabling centimeter-level accuracy.

3. Data Capture: Using Pix4Dcatch, the worker scans the area, capturing high-resolution images and LiDAR data.

4. AR Visualization: Pix4Dcatch's AR feature overlays existing GIS data onto the live camera view, guiding the worker to the precise location of the buried asset.

5. 3D Modeling: The collected data is processed to create a detailed 3D digital twin of the site, documenting the asset's exact position and surrounding environment.

This integration of advanced GNSS technology with real-time data capture and augmented reality streamlines the utility worker's task, enhancing accuracy and efficiency in locating and documenting underground assets.
