A software program that automatically detects ships from high resolution commercial overhead imagery and quickly outputs the results in various user-friendly formats.
The U.S. Navy seeks to commercialize U.S. Patent 8,116,522 (Ship detection system and method from overhead images); and U.S. Patent Apps.12/711,110 (Method for classifying vessels using features extracted from overhead imagery); 12/851,738 (Method for fusing overhead imagery with automatic vessel reporting systems); and 13/032,712 (Adaptive automated synthetic aperture radar vessel detection method with false alarm mitigation).
High-resolution commercial satellite images allow ships to be seen from space, providing unsurpassed ocean surveillance capabilities for maritime law enforcement, disaster responders, port authorities, and search and rescue teams. Manual systems for detecting ships in high-resolution imagery take considerable time, requiring an image analyst to search for ships. Automated systems are faster, but often demand multiple user inputs, produce too many false detects, and do not take full advantage of panchromatic data - data that, if processed correctly, could provide improved capabilities for ship detection in clouds, noise, etc. A fully automated system that effectively processes such data could offer more detailed results, less false detects, and save the user time.
RAPIER® SDS is a software program that uses a suite of advanced image processing algorithms to automatically detect ships from high resolution commercial satellite imagery (Figures 1-4). For EO/IR processing, the algorithms mask land, detect and remove clouds, analyze background textures, remove glint and noise, detect anomalies, and measure and type ships (Figures 1-2). Results are output in various user-friendly formats, including a KMZ file for overlay onto Google Earth™ (Figure 4), and an easy to read HTML file (Figure 3) that lists and organizes data according to ship size.
