Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the location of roadside parking spaces are hindered by inaccurate data from public sources, which can lead to incorrect positioning and difficulty in finding available parking spaces.
Innovation Solution
The method involves combining parking information from a publicly accessible data source with high-precision map data from a navigation system to correct the geometric and semantic information of parking spaces, ensuring accurate representation and easy identification of available spaces.

Engineering Contradiction Analysis
1Quantity of substance
If parking space information is obtained from publicly accessible data sources, then the coverage and availability of parking space data is improved, but the accuracy of position information deteriorates
Solution Approach 1:
The patent combines data from multiple sources: publicly accessible parking space information (providing coverage) with high-precision map data from navigation systems (providing accuracy). By merging these data sources and using the road course as a reference framework, the system achieves both broad coverage and precise positioning for parking spaces.
2Measurement precision
If sensor scanning is used to determine parking space positions, then the real-time accuracy of parking space detection is improved, but the complexity of scanning and interpreting sensor data increases
Solution Approach 1:
The patent introduces road course information from high-precision maps as an intermediary reference framework. Instead of directly scanning and interpreting complex sensor data to determine parking space positions, the system uses the pre-defined road course as a mediator to simplify the detection process and improve accuracy.
3Speed
If parking space position information is used directly from data sources, then the speed of obtaining parking information is improved, but the reliability of navigation to parking spaces deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where parking space information from various data sources is continuously refined and corrected using high-precision road course data. This feedback loop ensures that the navigation system maintains both fast access to parking information and high reliability in guiding vehicles to the correct parking spaces.

AI summary
The invention relates to a method for determining a roadside parking space comprising the following steps: a start position and an end position of the parking space is determined, the parking space extending between the start position and the end position; position of a course of the road in the region of the start and the end position of the parking space is determined; the position of the parking space is imaged with respect to the course of the road such that the imaged parking space extends directly adjacent to the road.
