Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple range image cameras are arranged to acquire overlapping range images, then a wider angle of view and higher range accuracy are achieved, but the installation operation becomes troublesome and time-consuming due to repetitive visual checking and adjustment
Solution Approach 1:
The patent replaces the manual visual checking and adjustment process with an automated optical measurement system. The range image cameras capture images of installation mark positions, and a computer automatically calculates installation states and provides quantitative feedback, eliminating the need for repetitive manual visual inspection and physical adjustment of multiple camera units.
Solution Approach 2:
The system enables self-checking of installation states by automatically capturing images of installation marks, processing the images to determine camera positions and orientations, and providing quantitative installation state information without requiring manual intervention for each checking operation.
2Area of stationary object
If multiple range image cameras are arranged to acquire overlapping range images, then a wider angle of view is achieved, but the installation operation becomes troublesome due to repetitive visual checking
Solution Approach 1:
The patent replaces manual visual checking with automated optical image capture and computer-based processing. The system automatically captures images of installation marks using the range image cameras, processes these images to calculate installation states, and provides quantitative feedback, making the installation operation simpler and more efficient.
Solution Approach 2:
The patent introduces installation marks as intermediary objects that facilitate the measurement and verification of camera installation states. These marks serve as reference points that the range image cameras capture, enabling automatic calculation of installation positions and orientations without requiring direct manual measurement or visual checking of camera alignments.
3Difficulty of detecting and measuring
If manual visual checking is used to verify camera installation state, then qualitative assessment is possible, but quantitative measurement of installation state is not achieved
Solution Approach 1:
The patent replaces qualitative visual assessment with quantitative optical measurement. The range image cameras capture images of installation marks, and a computer automatically processes these images to calculate precise numerical values for camera positions and orientations, providing objective quantitative measurement data instead of subjective qualitative judgments.
Solution Approach 2:
The patent transitions from two-dimensional visual inspection to three-dimensional quantitative measurement by using range image cameras to capture spatial information of installation marks and calculating precise positional and orientational data in three-dimensional space, enabling comprehensive quantitative assessment of installation states.
