Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image quality experiments are conducted in actual tunnel sites, then real field conditions are captured, but it is difficult to optimize equipment and conduct controlled experiments
Solution Approach 1:
The patent creates a simulated tunnel environment that copies real tunnel conditions (curvature, lighting, dust) in a controlled indoor setting. This allows experiments to be conducted without actual tunnel sites while maintaining realistic testing conditions, resolving the contradiction between reliability and adaptability
2Measurement precision
If various camera settings are tested in real tunnel conditions, then optimal settings for field conditions are found, but on-site experiments are difficult to conduct
Solution Approach 1:
The patent introduces an image processing system that acts as an intermediary between the camera and the analysis process. This system automatically adjusts settings, processes images, and analyzes quality metrics, making precise measurement accessible without requiring complex on-site experimental setups
3Speed
If high-speed photographing is performed to match tunnel driving speeds, then realistic motion conditions are captured, but motion blur and image quality vary
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that automatically modify camera settings (shutter speed, aperture, ISO) based on the photographing speed and detected motion conditions. This allows the system to maintain image quality consistency while operating at high speeds by adaptively optimizing parameters in real-time

AI summary
Disclosed are a system and a method for simulation of mobile camera photographing, and a recording medium in which a computer-readable program for executing the method is recorded. The system for simulation of mobile camera photographing comprises an image acquisition unit, a panel information input unit, an image acquisition unit information input unit, and an image information calculation unit. The image acquisition unit acquires an image of a panel moving in a preconfigured direction and speed, the panel information input unit receives an input of operation information of the panel, the image acquisition unit information input unit receives an input of configuration information of the input acquisition unit, and the image information calculation unit calculates image feature information corresponding to the operation information of the panel and the configuration information of the image acquisition unit. By this configuration, a simulated photographing environment reflecting various field conditions is created and thus image quality experiments using various types of cameras are possible.
