Multi-Sensor Data Fusion

As a pioneer in the use of simultaneous, multiple sensor data acquisition, Merrick & Company has the resources and capabilities to provide high accuracy, co-registered data products. To accomplish this, Merrick can integrate multiple sensors within a single airborne platform. Utilizing a multi-sensor data collection approach provides many benefits including:

The system decreases project costs by utilizing a “single pass” philosophy”. It is far more efficient to fly an area-of-interest (AOI) in a single mission rather than two or more separate missions.
Improved Accuracy
The system improves positional accuracy of the individual data products because the data is co-registered to a single, highly accurate inertial measurement system.
Data Synergy
The resulting data fusion from these sensors can significantly improve the data exploitation, feature extraction and analysis capabilities of the acquired data sets.

Merrick’s multi-sensor data acquisition system is integrated with an airborne global positioning system (GPS) and an inertial measurement unit (IMU) to provide real-world coordinates for positional accuracy and orientation during data collection. The result is a more accurate geospatial data product that allows for precise measurement and interpretation by the client. Merrick’s multi-sensor data acquisition system may include the following component sensor systems:

Light Detection & Ranging (LiDAR) Scanner
Provides elevation information for 3D visualization, exploitation & analysis.

Digital Camera System
Supplies high-resolution imagery for orthophotography production and visual analysis.

VNIR/SWIR Hyperspectral Imagers
Provides full spectrum data acquisition for land use/land cover classification, material composition analysis and soil/bedrock analysis.

Thermal Sensor
Determines an object’s temperature data for facility & situational analysis.

Video Camera System
Captures high resolution, color video to support facility inspections and site analysis.
