1Productivity

If ultrasonic radar sensors are used for parking space detection, then detection capability is provided, but identification efficiency is low

Engineering Contradiction:
Improveidentification efficiencyVSAvoidtime consumption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces ultrasonic radar sensors with a camera-based visual detection system. The camera captures images of the surrounding environment, and image processing algorithms identify parking spaces by analyzing visual features such as lines, regions, and semantic information. This substitution of mechanical sensing with optical sensing and computational analysis significantly improves identification efficiency while reducing time consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital representation of the physical parking environment by capturing images with a camera and processing them through image analysis algorithms. Instead of directly measuring physical distances with ultrasonic sensors, the system creates an image-based model of the scene, segments it into grids, and identifies parking spaces through semantic analysis of the copied visual information, thereby improving detection speed and efficiency.

Inventive Principle:
Principle #26Copying

2Measurement precision

If conventional ultrasonic radar methods are used, then parking space detection is achieved, but accuracy and efficiency need improvement

Engineering Contradiction:
Improveparking space identification accuracyVSAvoiddetection efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent divides the captured image into multiple grid regions and further segments each grid into sub-regions for detailed analysis. By segmenting the image space and processing each segment independently with appropriate algorithms, the system achieves higher identification accuracy for parking spaces while maintaining efficient processing through parallelization of the segmented regions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different processing strategies to different regions of the image based on their characteristics. For example, certain grids may receive more detailed semantic segmentation while others use simpler line detection. This localized adaptation of processing quality optimizes both accuracy for critical regions and efficiency for less critical regions, resolving the contradiction between precision and productivity.

Inventive Principle:
Principle #3Local quality
