Aerial Image Abnormality Detection and Reshoot System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial imagery often suffers from abnormalities such as streaks and smears caused by external reflections, leading to time delays and costly re-flights, as existing systems cannot detect and address these issues in real-time during image capture.
Innovation Solution
An image capture system equipped with event multiplexer systems and detection algorithms that immediately detect abnormalities and automatically trigger re-shooting of affected areas, combining pixels from multiple images to form a complete and undistorted image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If real-time abnormality detection is implemented, then time delays and re-flight costs are reduced, but device complexity increases
Solution Approach 1:
The system performs preliminary abnormality detection during the image capture process itself, rather than waiting for post-processing. The detection computer analyzes images as they are captured by the camera, enabling immediate identification of abnormalities before the flight is completed and processed later.
Solution Approach 2:
The system implements a feedback loop where detection results are immediately communicated back to the flight operations. When an abnormality is detected, the system provides real-time feedback that triggers automatic rescheduling of re-shoots, creating a closed-loop control system that continuously monitors and responds to image quality.
2Manufacturing precision
If multiple images are captured and combined, then image quality is improved, but processing time increases
Solution Approach 1:
The system performs preliminary combination of multiple images during or immediately after capture, rather than waiting for post-flight processing. By combining images preliminarily and detecting abnormalities in real-time, the system reduces the overall processing time while maintaining image quality standards.

AI summary
Am image capture system for capturing images of an object, the image capture system comprising a moving platform such as an airplane, one or more image capture devices mounted to the moving platform, and a detection computer. The image capture device has a sensor for capturing an image. The detection computer executes an abnormality detection algorithm for detecting an abnormality in an image immediately after the image is captured and then automatically and immediately causing a re-shoot of the image. Alternatively, the detection computer sends a signal to the flight management software executed on a computer system to automatically schedule a re-shoot of the image. When the moving platform is an airplane, the detection computer schedules a re-shoot of the image such that the image is retaken before landing the airplane.
