Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned flying bodies with cameras can capture images anywhere, raising concerns about privacy and security, as there are currently no restrictions on image acquisition, recording, or reproduction, especially in sensitive areas or situations.
Innovation Solution
An image management system that includes a drive control block, image acquisition block, image recording block, and restriction block to control and manage camera images based on the unmanned moving body's flight state and camera attitude, preventing unauthorized image acquisition, recording, and reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the unmanned flying body is allowed to move freely and capture images without restriction, then the versatility and image-taking capability in various locations is improved, but privacy and security risks increase
Solution Approach 1:
The system performs preliminary actions by setting no-fly zones and image capture restrictions before the unmanned flying body operates. The restriction block pre-defines geographic areas and conditions where image capture is prohibited, preventing privacy violations before they occur rather than reacting after images are taken.
Solution Approach 2:
The restriction block acts as an intermediary between the image acquisition block and the external environment. It mediates by monitoring flight state and camera attitude in real-time, and selectively blocking image capture when the flying body enters restricted zones or adopts prohibited camera orientations, thus protecting privacy without completely disabling the imaging capability.
2Reliability
If the restriction block is added to manage image acquisition and recording, then privacy and security are improved, but device complexity increases
Solution Approach 1:
The restriction block is designed to perform multiple functions within a single component: it monitors no-fly zone entry, tracks camera attitude angles, determines restriction conditions based on combined parameters, and controls both image acquisition and recording. This multi-functionality reduces the need for separate dedicated components for each restriction function.
Solution Approach 2:
The system merges the restriction control functions with the existing flight control and image processing systems. The restriction block integrates with the drive control block and image acquisition block, sharing data on flight state and camera attitude, thereby avoiding the need for entirely separate independent restriction systems.
3Measurement precision
If real-time monitoring of camera attitude and flight state is implemented, then image capture accuracy in restricted zones is improved, but processing time and computational load increase
Solution Approach 1:
The system applies partial monitoring by focusing computational resources on critical parameters only. Instead of analyzing all possible flight and camera parameters, the restriction block specifically monitors no-fly zone position, camera pitch angle, and roll angle - the minimum necessary parameters to determine restriction conditions, reducing processing overhead while maintaining sufficient precision.
Solution Approach 2:
The restriction block uses self-service by leveraging data already available from the flight control system and camera gimbal system. Rather than implementing separate sensing and processing systems, it utilizes the existing flight state data and camera attitude information that are already being measured and processed for normal flight control, avoiding redundant computational loads.

AI summary
In an image management system 100, an unmanned flying body 1 acquires a camera image during the flight of the unmanned moving body, an image accumulating server 30 records the camera image, and a reproduction terminal apparatus 40 reproduces the camera image. If a predetermined subject is determined included in the camera image, then one of the acquisition processing, the recording processing, and the reproduction processing to be executed on an camera image is restricted. Further, if an image-taking prohibited area is determined included in an image-taking range of a camera, one of the acquisition processing, the recording processing, and the reproduction processing to be executed on the camera image is restricted.
