Solution Overview
Problem
Existing photographing plan creation systems fail to effectively identify and prioritize changed points among target objects, making it difficult to extract changes from large numbers of monitored points.
Innovation Solution
A device and method that includes a photographed data reception part, a change determination part, a photographing possibility determination part, and a photographing plan creation part to create a plan that prioritizes photography of extracted changed points, using statistical processing and threshold settings to differentiate between actual changes and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If photographing plan is created without change detection, then creation time is reduced, but ability to extract changed points from target points deteriorates
Solution Approach 1:
The system performs change detection by comparing current photographed data with past photographed data before finalizing the photographing plan. This preliminary action of change detection enables the system to identify and prioritize changed points, ensuring that the photographing plan focuses on areas that have actually changed rather than wasting time on unchanged areas.
Solution Approach 2:
The system uses feedback from change detection results to dynamically adjust the photographing plan. By comparing current data with past data and identifying changed points, the system receives feedback about which areas require prioritized photography, allowing the plan creation process to adapt and focus resources effectively.
2Device complexity
If all target points are photographed equally, then photographing plan simplicity is maintained, but priority of changed points cannot be extracted
Solution Approach 1:
The system applies local quality by differentiating the treatment of different target points based on their change status. Changed points receive prioritized photography attention while unchanged points are handled differently, creating a non-uniform photography plan that adapts to local conditions and ensures changed points are captured with appropriate priority.
Solution Approach 2:
The system segments the photographing plan into different categories based on change detection results. Target points are divided into changed points and unchanged points, allowing the system to apply different photography priorities and strategies to each segment, thereby maintaining plan simplicity while achieving precise changed point identification.
3Measurement precision
If statistical processing is applied to extract changed points, then changed point extraction accuracy is improved, but processing time increases
Solution Approach 1:
The system changes parameters such as threshold values and statistical processing methods to optimize the balance between accuracy and processing time. By adjusting these parameters, the system can achieve sufficient changed point extraction accuracy without excessive processing time, adapting the statistical processing intensity to the specific task requirements.

AI summary
The present invention provides a device for creating a photographing plan by extracting a changed point from target points to preferentially photograph the extracted point. The photographing plan creation device includes: a photographed data reception part for receiving a first photographed data photographed by a flying object; a change determination part for comparing the first photographed data to a second photographed data which is the past photographed data stored in an image data storage part; a priority setting part for setting the shooting priority based on the comparison result; a photographing possibility determination part for determining whether photography is possible at the observation time; a photographing plan creation part for creating a photographing plan based on the shooting priority and the photographing possibility determination; and a shooting command transmission part for converting the photographing plan to a command and transmitting the command to the flaying object.
