Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the position of a target, such as in military and civilian applications, are often cumbersome, requiring heavy equipment, time-consuming calibration procedures, and manual labor, which can be impractical in time-sensitive and weight-constrained situations.
Innovation Solution
A method and system utilizing a geo-referenced three-dimensional map on a wearable device that allows observers to mark and determine the position of a target without heavy equipment, enabling fast and accurate coordinate acquisition without the need for extensive training or external communication, using a range and direction measuring device for initial coordinates and a satellite-based navigation system for observer positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods using laser rangefinder and digital compass are employed, then target position determination accuracy is improved, but equipment weight and calibration time increase
Solution Approach 1:
The patent uses a pre-acquired image of the target area as a reference copy. The observer marks the target position on this copied image, which is then correlated with satellite stereo imagery to determine precise coordinates. This eliminates the need for heavy traditional surveying equipment while maintaining accuracy through image-based reference.
Solution Approach 2:
The patent replaces mechanical surveying equipment (laser rangefinder, digital compass, physical calibration tools) with an image-based system using smartphone cameras, satellite imagery, and computational correlation. This substitution dramatically reduces equipment weight while achieving comparable or superior positioning accuracy.
2Measurement precision
If traditional methods using laser rangefinder and digital compass are employed, then target position determination accuracy is improved, but calibration time increases
Solution Approach 1:
The patent performs preliminary actions by pre-acquiring images of the target area and pre-establishing the coordinate system transformation relationships between different image sources. When the observer needs to mark a target, the system has already prepared the reference imagery and correlation algorithms, eliminating time-consuming on-site calibration while maintaining high positioning accuracy.
3Measurement precision
If satellite stereo imagery with manual surveying is used, then target coordinates are obtained, but time consumption and manual labor increase
Solution Approach 1:
The patent implements self-service through automated image correlation algorithms that automatically match the observer's marked position on the reference image with corresponding features in satellite stereo imagery. The system performs the complex stereo correlation and coordinate transformation automatically without requiring manual surveying or back-office processing, dramatically increasing targeting speed while maintaining accuracy.
4Measurement precision
If complex equipment and procedures are used, then measurement accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent presents the observer with a copied and processed view of the target area that is already georeferenced and aligned. The observer simply marks the target position on this prepared image copy, eliminating the need to understand complex coordinate systems or perform manual measurements. The system handles all complex transformations in the background, making the operation as simple as marking a point on an image while maintaining high positioning accuracy.
