Vehicle Parking Control Using Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking assistance systems for vehicles lack an intuitive and efficient method for driver supervision during automated parking operations, especially when the driver is outside the vehicle, requiring specialist equipment and reducing system processing efficiency.
Innovation Solution
A parking control system that includes a position determination module to locate a wireless driver device, a vision system control module to provide video data with a selected field of view, and a gesture determination module to recognize commands from the driver, allowing for intuitive control of the parking assistance system without the need for specialist devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera captures a wide field of view to monitor the driver outside the vehicle, then the driver can be detected, but system processing efficiency decreases due to processing unnecessary data
Solution Approach 1:
The patent divides the monitoring system into two stages: first, a wide-field camera captures the entire area to locate the driver; second, a zoom lens focuses on the driver's specific region. This segmentation allows the system to process only relevant data for gesture recognition, improving efficiency while maintaining detection accuracy.
Solution Approach 2:
The patent applies different optical qualities to different regions of interest. The zoom lens provides high magnification and detail for the driver's hands and gestures, while the wide-field camera provides broad coverage for context. This local quality optimization ensures processing resources are concentrated where needed.
2Measurement precision
If a zoom lens is used to focus on the driver's hands for gesture recognition, then gesture detection accuracy improves, but the field of view is reduced making driver location difficult
Solution Approach 1:
The patent merges two camera systems with different field of view characteristics into a coordinated system. The wide-field camera locates the driver, and the zoom lens focuses on the hands. Both systems work together seamlessly, with the wide-field view providing context and the zoom view providing detailed gesture data.
Solution Approach 2:
The patent performs preliminary driver location using the wide-field camera before activating the zoom lens for detailed gesture analysis. This preliminary action ensures the zoom lens is positioned correctly and only processes relevant data, avoiding the need for a continuously wide field of view during gesture recognition.
3Adaptability or versatility
If the camera continuously captures the entire parking area, then all potential gestures are visible, but data processing time and computational resources increase
Solution Approach 1:
The patent extracts only the relevant portion of the scene (the driver's hands) using the zoom lens after locating the driver with the wide-field camera. This extraction eliminates unnecessary data processing while maintaining comprehensive gesture detection coverage, as the system focuses computational resources only on the area containing potential gestures.
Data Source
AI summary
Methods and Systems are provided for performing an automated parking operation of a vehicle. The methods and systems determine a position of a wireless driver device located outside of the vehicle. A vision system provides video data having a field of view selected based on the position of the wireless driver device. Gesture recognition processing is performed on the video data having the selected field of view. At least one gesture command is determined from the gesture recognition processing. An automated parking operation of the vehicle is performed using the at least one gesture command.
