Electronic Map Image Reproduction Using Azimuth and View Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic map systems can only display images of target points if an image file is specifically registered at that location, and do not utilize adjacent image files, limiting user functionality and information retrieval.
Innovation Solution
An image reproduction method and apparatus that selects a target point on an electronic map, sets a search range, searches for image files within that range using position, azimuth, and view angle information, and displays images of adjacent files that include the target point, using formulas to determine alignment and relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image files are only displayed when registered at the exact target point position, then position accuracy is improved, but image availability deteriorates
Solution Approach 1:
The patent applies partial action by searching for image files within a partial area (surrounding region) rather than requiring exact position matching. The system determines whether adjacent image files partially contain the target point by calculating azimuth angles and view angles, allowing display of images that are not perfectly aligned but still relevant to the target location.
2Loss of information
If the search range for image files is expanded to include adjacent locations, then image availability is improved, but position precision deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the matching criteria based on location. Image files located at the exact target point position are matched with high precision requirements, while adjacent image files are evaluated using azimuth angle and view angle calculations. This allows the system to expand the search range to surrounding areas while maintaining appropriate precision standards for each location type.
3Reliability
If only image files registered at the target point position are displayed, then data accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically evaluate and select appropriate image files without requiring complex manual configuration. The image reproduction apparatus autonomously calculates azimuth angles, determines view angles, and identifies suitable adjacent image files based on the stored position information and camera parameters, reducing the need for complex user intervention or system configuration.
4Ease of operation
If adjacent image files are utilized to display target point images, then user convenience is improved, but calculation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing essential parameters (position information, azimuth angles, view angles, camera focal lengths) in the image file metadata during the image capture and registration phase. This preliminary preparation allows the reproduction apparatus to quickly retrieve and calculate the necessary information when displaying images, avoiding the need for complex real-time computations and reducing operational complexity for the user.

AI summary
An image reproduction apparatus for displaying images of image files including an image of a target point to be observed by using image files located adjacent to the target point. A method of reproducing an image of an image file on an electronic map including the image file so that position information of the image file matches position information on the electronic map includes: (a) selecting a target point to be observed on the electronic map and obtaining position information of the target point; (b) setting a search range of image files on the electronic map; (c) searching for image files including an image of the target point within the set search range; and (d) displaying images of the found image files on the electronic map.
