Solution Overview
Problem
Current systems lack efficient methods for precision targeting in tactical operations, particularly in scenarios where resources are limited, and existing technologies struggle to provide accurate and timely imagery for guiding munitions without the need for advanced computational resources.
Innovation Solution
A computer-readable medium encoded with a Precision Fires Image (PFI) format that includes a geo-referenced 3-D template and stereo-referenced imagery, allowing for precise targeting coordinates to be generated on handheld devices, even in the absence of advanced computational systems, using the Digital Point Positioning Database and edge extraction algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If advanced computational systems are used for precision targeting, then targeting accuracy is improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent segments the image data into displayable and non-displayable portions, with the non-displayable segment containing the 3-D template used for coordinate calculation. This allows the complex computational task to be separated from the display function, enabling precision targeting through simple overlay operations on low-capacity devices.
Solution Approach 2:
The 3-D template and coordinate transformation data are pre-calculated and embedded in the non-displayable image segment before transmission. This preliminary computation eliminates the need for complex real-time calculations on the handheld device, achieving high targeting accuracy through pre-prepared data structures.
2Measurement precision
If detailed terrain information is provided for precision targeting, then targeting precision is improved, but data transmission and storage requirements increase
Solution Approach 1:
The patent extracts only the essential 3-D template data and coordinate transformation information into a separate non-displayable image segment, removing unnecessary detailed terrain visualization data. This extraction maintains targeting precision while reducing the overall data volume transmitted and stored.
Solution Approach 2:
The patent uses a simplified 2-D representation of the 3-D terrain in the displayable image segment, while the actual 3-D template resides in the non-displayable segment. This copying approach allows detailed terrain information to be used for precision calculations without requiring the full 3-D data to be visible or transmitted in high detail.
3Measurement precision
If stereo-referenced imagery is used for 3-D template creation, then coordinate accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The stereo-referenced imagery processing and 3-D template creation are performed in advance during image generation, not during the targeting operation. This preliminary action allows coordinate accuracy to be achieved through pre-computation, eliminating time-consuming 3-D processing from the real-time targeting workflow on handheld devices.
