Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in quickly identifying suitable parking spots, often requiring multiple attempts to find a suitable space due to the lack of immediate information about available parking areas.
Innovation Solution
A parking spot detection system that integrates parking spot information into a map using a detection unit to acquire position and intensity data, determining geometric shapes to identify parking spaces and integrating this information into map data for real-time navigation and automatic or auxiliary parking assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If drivers manually search for parking spots by driving around, then they can eventually find a suitable parking spot, but it consumes excessive time and requires multiple attempts
Solution Approach 1:
The system performs preliminary detection and mapping of parking spots in advance, storing their locations and characteristics in a database before the driver needs them. When the driver enters a parking area, the system quickly retrieves pre-processed parking spot information rather than requiring real-time manual search, significantly reducing the time and effort needed to find suitable parking spots.
2Measurement precision
If the system processes detailed intensity data from detection units to accurately identify parking spaces, then detection precision improves, but system complexity increases
Solution Approach 1:
The system segments the complex detection task into distinct modules: the detection unit captures raw intensity data, the processing unit analyzes geometric shapes and identifies parking spaces by processing this data, and the map integration unit incorporates detected spaces into the overall map. This segmentation allows each module to focus on a specific function, improving detection precision while managing system complexity through modular design.

AI summary
A parking spot detection system is provided with a detection unit, a map database and a processing unit. The detection unit acquires position data and intensity data of a plurality of data points in an environment space. The map database provides map information. The processing unit is coupled to the detection unit and the map database and determines whether a geometric shape formed by adjacent data points is of a parking space according to the intensity data of the data points; and if the geometric shape is determined to be of the parking space, the processing unit further integrates the geometric shape and the position of the parking space into the map data according to the position data of the data points.
