Aerial Image Directional Alignment on Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques for understanding the directional relationship between aerial photographs and electronic maps are not intuitive, making it difficult to visualize the correspondence between the two.
Innovation Solution
An image processing device and method that displays a quadrangular-shaped photographic image from an aerial vehicle on a wide area image, with a mark indicating the photographing position and performing highlight display to align the image direction with the map direction, allowing for intuitive understanding of the directional relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mark indicating photographing position is displayed on a wide area image, then the position relationship is clarified, but the directional relationship between the photographed image and the map remains difficult to understand
Solution Approach 1:
The patent applies color highlighting to specific sides of the quadrangular mark and corresponding sides of the photographed image. By changing the color (e.g., to red or another distinctive color) of the highlighted sides, the system visually indicates the directional correspondence between the photograph and the map, making it intuitive to understand which direction the camera was pointing when the image was captured.
Solution Approach 2:
The patent transitions from a two-dimensional representation to a three-dimensional visual effect by applying highlight display that simulates depth and orientation. The highlighted sides create a visual dimension that extends beyond the flat map surface, allowing users to perceive the spatial orientation and directional relationship between the aerial photograph and its corresponding location on the map.
2Quantity of substance
If photographing is performed by manned or unmanned aerial vehicle, then topographic data can be obtained, but it becomes difficult to intuitively understand the directional relationship between photographed images and electronic maps
Solution Approach 1:
The patent uses color highlighting on the quadrangular mark's sides to visually encode directional information. When multiple photographs are taken from an aerial vehicle, each photograph's corresponding mark on the map is highlighted with colored sides that match the orientation of the photograph, enabling intuitive understanding of the camera's direction and position relative to the terrain being photographed.
Solution Approach 2:
The patent creates a visual copy of the directional information by representing the photographed image as a quadrangular mark on the map. The mark is not merely a position indicator but a directional copy that replicates the orientation and angle of the actual photograph, allowing users to understand the spatial relationship without needing to view the actual image.

AI summary
A technique enables intuitive understanding of a directional relationship between a photographed image and a wide area image, such as an electronic map. An image processing device includes a display controlling unit that displays a quadrangular-shaped photographic image, which is photographed from an aerial vehicle, displays a mark indicating a photographing position of the quadrangular-shaped photographic image, on a wide area image, and performs highlight display in accordance with a corresponding relationship between a direction of the quadrangular-shaped photographic image and a direction of the mark.
