Vehicle Edge Line Prioritization for Parking Detection

The patent extracts only the necessary edge lines for parking space detection by filtering out irrelevant edge lines from complex road surfaces. The extraction unit selectively identifies edge lines based on specific criteria (such as orientation, position, and visual characteristics) that are relevant to parking space delimitation, thereby reducing the total number of edge lines processed while maintaining detection accuracy.

The patent applies different processing qualities to different regions and types of edge lines. The evaluation unit assesses each edge line's local characteristics (such as its role in delimiting parking spaces versus marking road features) and applies selective registration only to edge lines that meet the criteria for parking space detection, optimizing the balance between completeness and processing time.

The patent applies partial action by registering only a subset of extracted edge lines rather than all of them. The registration unit selectively registers edge lines that meet specific criteria (such as those most likely to delimit parking spaces) while excluding those that are less relevant, thereby maintaining sufficient detection accuracy while reducing processing time.

The patent performs preliminary evaluation and sorting of edge lines before registration. The evaluation unit preliminarily assesses each edge line's suitability for parking space detection and ranks them accordingly, allowing the registration unit to process only the most promising candidates first, thus optimizing the balance between accuracy and speed.
