Parking Position Notification Using Camera and Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking position notification systems fail to accurately identify and notify users of their vehicle's location in various parking environments, especially in areas with limited GPS signal reception, such as underground garages and multi-level parking lots.
Innovation Solution
A parking position notification apparatus that uses a vehicle-mounted camera to capture images, sensors to determine movement routes, and a control unit to extract identification information from immovable objects, generating map data that includes the vehicle's parking position and optimal navigation routes, which can be transmitted to a user terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If GPS signals are used to notify parking position, then the notification method is simple, but it fails in areas with limited GPS signal reception such as underground garages and multi-level parking lots
Solution Approach 1:
The patent introduces immovable objects (such as pillars, walls, or fixed structures) as intermediary reference points within the parking lot. These objects serve as mediators between the vehicle's movement and the final parking position, allowing the system to track position through image recognition of these fixed references even when GPS signals are unavailable.
Solution Approach 2:
The patent replaces the GPS satellite-based electromagnetic positioning system with a local image recognition and sensor-based tracking system. By using cameras and sensors to capture and analyze images of immovable objects, the system substitutes the external GPS mechanical system with a localized optical and computational approach that works independently of satellite signals.
2Device complexity
If only GPS signals are used to calculate parking position, then the system structure is simple, but it cannot determine the level of the parking garage in multi-level structures
Solution Approach 1:
The patent adds vertical dimension detection by analyzing the spatial relationships between immovable objects across different levels of the parking garage. By tracking the positions and orientations of reference objects in three-dimensional space using image data, the system can determine not only horizontal position but also vertical level information.
3Measurement precision
If image analysis and sensor data are used to determine parking position, then notification accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent makes the existing vehicle camera and sensors serve multiple functions: they continue to capture images for their original purposes while simultaneously being used for parking position tracking by recognizing immovable objects. This multi-functionality approach allows the system to gain positioning capabilities without adding dedicated hardware for each function.
Solution Approach 2:
The system uses the vehicle's own existing imaging and sensing equipment to determine its parking position, rather than relying on external infrastructure or additional specialized hardware. The vehicle essentially services its own positioning needs using resources already available on board.
