Parking Assist Overhead Imaging for Route Position Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to objectively understand the positional relationship between the travel route of a vehicle based on teacher driving and objects and roads around it, especially when parking in fixed positions.
Innovation Solution
A parking assist method and device that acquire images from imaging devices installed in the vehicle, record the travel route, generate an enlarged overhead image of the display target range, and display it to the user, allowing for better visualization of the vehicle's route and its surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If teacher driving data is used for autonomous parking, then parking automation is achieved, but user understanding of positional relationship deteriorates
Solution Approach 1:
The patent creates a virtual copy of the real-world environment by generating an overhead image that replicates the spatial relationships between the vehicle, travel route, and surrounding objects. This virtual representation allows users to understand positional relationships without directly observing the physical environment, resolving the contradiction between automation and information loss.
Solution Approach 2:
The patent transforms the two-dimensional captured images into a three-dimensional overhead perspective view, adding a vertical dimension to the visualization. This dimensional change provides users with a comprehensive top-down view of the positional relationships, enabling better understanding while maintaining automation.
2Area of stationary object
If conventional overhead images are used, then complete route coverage is achieved, but detail visibility of peripheral objects deteriorates
Solution Approach 1:
The patent divides the overhead image into multiple regions: a first region displaying the travel route with high detail, and a second region displaying peripheral objects. This segmentation allows each region to be optimized for its specific purpose, maintaining both comprehensive coverage and detailed visibility.
Solution Approach 2:
The patent applies different visualization qualities to different regions of the overhead image. The travel route area receives enhanced detail and clarity, while peripheral areas maintain sufficient visibility. This local quality differentiation resolves the contradiction between comprehensive coverage and detailed visibility.

AI summary
A parking assist method according to the present disclosure is for performing autonomous driving of a vehicle on the basis of teacher driving by a driver. The parking assist method includes acquiring, from an imaging device installed in the vehicle, captured images obtained by imaging periphery of the vehicle in time series according to movement of the vehicle during the teacher driving. The method includes recording a travel route of the vehicle in the teacher driving, and generating, on the basis of the captured images, a first enlarged overhead image of a display target range viewed from above. The display target range covers the travel route and periphery of the travel route. The method further includes causing a display device to display the first enlarged overhead image.
