Marker-less Automatic Parking via Virtual Bird's-Eye View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking systems rely on markers in the parking lot, limiting their ability to guide vehicles to desired parking spaces without pre-designated markers.
Innovation Solution
An automatic parking apparatus equipped with a monitor device for photographing surroundings, an image display device for user input, and a vehicle control device to calculate and execute a moving path to a user-designated parking area, allowing for marker-less parking space selection and guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If marker recognition is used for automatic parking, then parking guidance accuracy is improved, but parking lot adaptability deteriorates
Solution Approach 1:
The system creates a virtual copy of the parking lot environment using image data from monitor devices. Instead of relying on physical markers, the system generates a bird's-eye view image that replicates the parking space layout and uses this virtual representation for guidance, enabling operation in marker-less environments while maintaining accuracy.
Solution Approach 2:
The patent replaces the mechanical marker-based recognition system with an image processing and computer vision system. The marker recognition device is substituted by monitor devices that capture images, which are then processed to generate bird's-eye view images and detect parking spaces automatically, eliminating the need for physical markers.
2Device complexity
If marker-based automatic parking is implemented, then system simplicity is improved, but user flexibility deteriorates
Solution Approach 1:
The system presents users with a virtual bird's-eye view copy of the parking area on a display device, allowing them to visually select their desired parking space. This virtual representation maintains system simplicity while dramatically improving user flexibility, as users can now choose from multiple parking spaces rather than being directed to a single marker-designated space.
3Measurement precision
If marker recognition devices are used, then parking space detection precision is improved, but system versatility deteriorates
Solution Approach 1:
The patent substitutes the specialized marker recognition device with a general-purpose image capture and processing system. Monitor devices capture images of the parking area, and image processing algorithms automatically detect parking spaces based on visual features in the images, enabling the system to operate in both marker-equipped and marker-less environments with comparable detection precision.
