Engineering Contradiction Analysis
1Reliability
If vehicle sensors are used to detect parking environment, then detection function is provided, but erroneous detection occurs due to sensor sensitivity, shadows, and other factors
Solution Approach 1:
The patent introduces an image processing system as an intermediary between the sensor data and the final state determination. The camera captures images of the parking environment, and image processing algorithms analyze these images to verify or correct sensor-based detections, thereby reducing erroneous detections while maintaining reliable detection coverage
Solution Approach 2:
The patent merges sensor-based detection with image-based detection into a unified state determination system. By combining data from both sensors and image processing, the system achieves more accurate and reliable vehicle state determination than either method could provide alone, compensating for the weaknesses of sensor-only approaches
2Measurement precision
If image processing procedures are performed to improve detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the image processing into distinct functional modules: image acquisition, image preprocessing, feature extraction, and state determination. This segmentation allows each module to be optimized independently and facilitates efficient implementation, reducing the practical complexity despite the sophisticated processing required for high accuracy
