Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques face difficulties in setting and adjusting a curved passage detection line on captured images due to image distortion, leading to disparities between the figures settable on captured and corrected images, which prevents accurate image analysis by image capturing apparatuses.
Innovation Solution
An image processing apparatus that converts position information of a figure set on a corrected image into a format usable by the image capturing apparatus, using distortion correction information to ensure compatibility and enable analysis processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distortion correction processing is executed to generate a corrected captured image, then the ease of operation for setting figures is improved, but a disparity arises between figures settable on corrected images and those settable on captured images
Solution Approach 1:
The system introduces an intermediary conversion process that translates figure position information between the corrected image coordinate system and the captured image coordinate system. This mediator enables users to set figures on the corrected image while automatically converting them to the appropriate format for the image capturing apparatus, resolving the incompatibility issue.
Solution Approach 2:
The system changes the parameter representation of figure positions by maintaining position information in the captured image coordinates while allowing user interaction on corrected image coordinates. Through coordinate transformation based on distortion correction parameters, the system enables seamless operation on corrected images while ensuring compatibility with the image capturing apparatus.
2Measurement precision
If a curved line is used as a passage detection line to accommodate image distortion, then the measurement precision is improved, but the ease of operation for adjusting and setting the curved line deteriorates
Solution Approach 1:
Instead of requiring users to manually adjust curved lines to match distortion, the system inverts the approach by allowing users to set straight lines on the corrected image and automatically converting them to the appropriate curved lines for the captured image. This reversal of the adjustment process significantly improves ease of operation while maintaining measurement precision.
Solution Approach 2:
The conversion unit acts as an intermediary that automatically transforms straight line settings from the corrected image coordinate system into curved line configurations suitable for the captured image. This mediator handles the complex curved line adjustment calculations, freeing users from manual curved line adjustment while ensuring accurate passage detection.

AI summary
In an information processing apparatus, a conversion unit converts position information indicated by a line or a figure set onto a corrected captured image generated through distortion correction processing executed on at least a part of a captured image captured by an image capturing apparatus into position information in the captured image by at least using information relating to a condition for executing analysis processing for analyzing the captured image. A control unit controls an analysis unit to execute the analysis processing using the position information converted by the conversion unit.
