Problem
Current precision targeting systems for military operations in densely populated urban areas face challenges due to the need for extensive computer resources, limited mobility, and high operator training requirements, making it difficult to generate accurate geodetic coordinates for guided munitions efficiently and effectively.
Innovation Solution
A computer program product and method that preprocesses stereo images using the Precision Fires Image (PFI) algorithm, allowing a user to designate a point for precision targeting coordinates on a handheld device, reducing memory requirements and enabling wireless communication for efficient generation and transmission of geodetic coordinates to guided munitions, utilizing National Imagery Transmission Format (NITF) files and stereo referenced imagery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If extensive computer resources (large memory, high throughput processing hardware, complex software applications) are used to generate accurate geodetic coordinates, then measurement precision is improved, but device complexity and loss of substance increase
Solution Approach 1:
The system divides the coordinate determination process into two stages: (1) preprocessing stereo images to create a Precision Fires Image (PFI) with embedded geodetic information, and (2) using the handheld device to capture and process only the necessary target coordinates from the PFI. This segmentation allows complex preprocessing to be done once, while field operations remain simple.
Solution Approach 2:
The system performs preliminary processing of stereo imagery to generate the Precision Fires Image (PFI) before field deployment. The PFI contains pre-computed geodetic coordinates and spatial relationships, eliminating the need for the handheld device to perform complex coordinate calculations in the field.
2Measurement precision
If laptop computers and cable connectors are used for precision targeting, then measurement precision is improved, but ease of operation and mobility worsen
Solution Approach 1:
The system replaces the mechanical laptop computer and cable connector system with a handheld electronic device that integrates all necessary processing capabilities. The handheld device captures images, accesses the PFI database, and computes coordinates electronically, eliminating physical cables and bulky equipment.
Solution Approach 2:
The handheld device performs multiple functions: capturing images, accessing the Precision Fires Image database, computing geodetic coordinates, and transmitting results. This multi-functionality consolidates what previously required separate laptop computers and external equipment into a single portable unit.
3Measurement precision
If traditional precision targeting systems are used, then measurement precision is improved, but loss of time and productivity worsen due to extensive operator training requirements
Solution Approach 1:
The system provides automated guidance and processing that reduces dependence on highly trained operators. The handheld device guides the observer through the targeting process, automatically performs coordinate calculations, and transmits results, allowing operators with minimal training to achieve accurate results.
Solution Approach 2:
The system changes the operational parameters from complex manual coordinate calculation and interpretation to simple image capture and automated processing. This parameter change transforms the operator's role from performing complex computations to operating a simplified interface, reducing training requirements.
