Video Display Using LoS-Matched Archived Segments in Low Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Platforms without Enhanced Vision Systems (EVS) or with poor-quality EVS images due to weather or light conditions face degraded situational awareness, necessitating a method to enhance operator awareness using previously captured video segments.
Innovation Solution
A system and method that utilize a data repository of previously captured video segments with metadata for Line-of-Sight information, allowing for the identification and display of Region-of-Interest (RoI) matching video segments from better conditions, adjusted to match current Line-of-Sight, and blended with real-time or Synthetic Vision System (SVS) data for improved situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If previously captured video segments are used to improve situational awareness, then visibility and situational awareness are improved, but device complexity increases due to data repository and processing requirements
Solution Approach 1:
The system performs preliminary actions by capturing and storing video segments during previous operations when conditions were favorable. These pre-captured segments are stored in a data repository with associated metadata, allowing them to be retrieved and displayed during current operations when visibility is poor, thereby improving situational awareness without requiring complex real-time processing during adverse conditions
Solution Approach 2:
The system creates copies of visual information by storing video segments from previous operations in a data repository. These copied video segments can be retrieved and displayed during current operations, providing a backup visual reference that improves situational awareness when real-time imaging is degraded by weather or light conditions
2Manufacturing precision
If video segments from previous operations are displayed, then image quality is improved, but loss of time occurs due to retrieval and matching processing
Solution Approach 1:
The system replaces mechanical search methods with automated computer-based processing. A processing resource automatically retrieves video segments from the data repository and matches them with current Line-of-Sight information using metadata, significantly reducing the time required to find and display relevant historical video segments while maintaining high image quality
Solution Approach 2:
The system uses feedback mechanisms where metadata from current operation (including Line-of-Sight information) is compared with metadata from previously captured video segments. This feedback loop enables automatic identification and retrieval of matching video segments, reducing manual search time while ensuring high-quality image selection
3Adaptability or versatility
If Line-of-Sight matching is performed to retrieve relevant video segments, then adaptability is improved, but measurement precision requirements increase for metadata comparison
Solution Approach 1:
The system changes parameters by storing multiple metadata attributes with each video segment, including Line-of-Sight information, timestamps, and operational conditions. During retrieval, the processing resource compares these parameters between current and historical segments, enabling adaptable selection of matching video segments while managing precision requirements through multi-parameter comparison rather than single-point measurement
Data Source
AI summary
A system for displaying videos, comprising a processing resource configured to: provide a data repository comprising a plurality of previously captured video segments (PCVSs) captured during previous operations of corresponding platforms, each being associated with metadata indicative of a Line-of-Sight (LoS) of a sensor, carried by the corresponding platform of the platforms used to capture the corresponding PCVS, with respect to a fixed coordinate system established in space, during capturing the corresponding PCVS; obtain an indication of a Region-of-Interest (RoI); identify one or more of the PCVSs that include at least part of the RoI, utilizing the LoSs associated with the PCVSs, giving rise to RoI matching PCVSs; and display at least part of at least one of the RoI matching PCVSs, being displayed RoI matching PCVSs, on a display of an operating platform to an operator of the operating platform during a current operation of the operating platform.
