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.
The system improves positional accuracy of the individual data products because the data is co-registered to a single, highly accurate inertial measurement system.
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:
Video Camera System
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.
Determines an object’s temperature data for facility & situational analysis.
Captures high resolution, color video to support facility inspections and site analysis.
