Route Surrounding Image Synthesis for Long-Range Parking Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to provide sufficient information about the surrounding environment along a vehicle's traveling route, especially for long-range parking, as they can only display areas near the vehicle and do not support the user with information about situations around the parking space.
Innovation Solution
A driving assistance device that cumulatively stores captured images from various cameras and synthesizes them with vehicle information to generate a route surrounding image, which is then displayed to assist the driver in navigating the vehicle's route, including long-range parking scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only captured images near the vehicle are displayed, then the display is simple and real-time, but the driver cannot understand situations in blind spots or distant areas along the traveling route
Solution Approach 1:
The system performs preliminary actions by cumulatively storing captured images from multiple cameras along the vehicle's traveling route before the actual parking maneuver. This allows the route surrounding image to be prepared in advance, providing the driver with information about distant areas and blind spots that would otherwise be unavailable during the parking operation.
Solution Approach 2:
The system creates a synthesized copy of the surrounding environment along the route by combining multiple captured images into a route surrounding image. This synthesized image provides a comprehensive view of the traveling path and distant areas without requiring the driver to physically travel the route to observe conditions.
2Loss of information
If captured images are cumulatively stored and synthesized to show distant areas, then comprehensive route information is provided, but the data processing and storage requirements increase
Solution Approach 1:
The system extracts only the necessary captured images along the calculated traveling route from the cumulative storage, rather than processing all stored images. This extraction approach provides comprehensive route information while reducing the quantity of data that needs to be processed and managed.
Solution Approach 2:
The captured images serve multiple functions: they are stored cumulatively for future route planning, used to generate route surrounding images for driver information, and can be synthesized from multiple camera angles. This multi-functionality maximizes the utility of stored data without proportionally increasing storage requirements.
3Adaptability or versatility
If only near-field areas are displayed during parking assistance, then the system is simple to implement, but long-range parking to distant spaces cannot be supported
Solution Approach 1:
The system dynamically adapts its functionality based on the parking scenario. For near-field parking, it can display simple real-time images, but for long-range parking to distant spaces, it automatically activates the route surrounding image synthesis capability. This dynamic adaptation provides versatility without requiring the system to always operate at maximum complexity.
Solution Approach 2:
The system transitions from displaying only two-dimensional near-field camera views to synthesizing a comprehensive route surrounding image that encompasses the entire traveling path and distant areas. This dimensional expansion in information coverage enables long-range parking support while maintaining system manageability through selective image synthesis.

AI summary
A driving assistance device includes: an image storage unit configured to cumulatively store captured images, each obtained by capturing an image of a surrounding environment by an imaging device provided in a vehicle, in association with vehicle information when capturing the respective captured images; an image synthesizing unit configured to synthesize the cumulatively stored captured images based on the vehicle information to generate a route surrounding image indicating a surrounding environment along a route on which the vehicle travels; and an image display unit configured to display the route surrounding image.
