Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple imaging devices are used to capture images of the spike barrier, then the accuracy of determining the vehicular approach prevention direction is improved, but the system complexity and resource consumption increase
Solution Approach 1:
The patent transforms 2D images from multiple imaging devices into a 3D vehicular plan view image through coordinate transformation and perspective correction. This dimensional transformation allows the system to achieve accurate spatial understanding of the spike barrier's orientation and approach prevention direction by synthesizing multiple 2D views into a comprehensive 3D representation, thereby improving measurement precision without requiring direct 3D sensors.
2Measurement precision
If complex image processing algorithms are used to determine the vehicular approach prevention direction, then the measurement precision is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent extracts only the essential geometric features needed for determining the vehicular approach prevention direction from the complex images. By identifying and isolating key parameters such as the spike barrier's orientation, the positions of vehicular immobility projections, and the relevant edges, the system avoids processing unnecessary image data. This selective extraction maintains measurement precision while significantly reducing computational complexity and processing time.
Solution Approach 2:
The system performs preliminary coordinate transformation and perspective correction on images before the main analysis. By pre-processing the images to establish a standardized vehicular plan view coordinate system and correct distortions in advance, the subsequent determination of the approach prevention direction becomes a simpler geometric calculation, reducing the computational burden during critical processing phases.
3Reliability
If detailed analysis of the spike barrier structure is performed to determine the approach prevention direction, then the reliability is improved, but the computational resources and processing time increase
Solution Approach 1:
The patent applies different processing intensities to different regions of the image based on their importance. The area containing the spike barrier and its immediate surroundings receives detailed analysis to accurately determine the approach prevention direction, while other regions are processed with lower intensity or skipped entirely. This localized quality approach ensures reliability in the critical measurement area while minimizing overall computational resource consumption.
