Parking Assist Overhead View for Teacher-Driven Route Visibility
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 the vehicle.
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 easier understanding of the positional relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional parking assist technology uses teacher driving to learn travel routes, then autonomous parking capability is achieved, but users cannot objectively understand the positional relationship between the travel route and surrounding objects and roads
Solution Approach 1:
The system creates a virtual copy of the real-world environment by generating an enlarged overhead image that replicates the spatial relationships between the travel route, vehicles, and surrounding objects. This virtual representation allows users to objectively understand the positional relationships without directly observing the actual scene, resolving the information loss caused by autonomous operation.
Solution Approach 2:
The system transforms the two-dimensional captured images into a three-dimensional overhead view by generating an enlarged overhead image that displays the travel route and surrounding objects from a top-down perspective. This dimensional transformation provides users with a comprehensive spatial understanding that is not available from ground-level camera views, enabling objective assessment of positional relationships.
2Loss of information
If the system displays normal overhead images, then users can see the vehicle position, but they cannot clearly understand the positional relationship between the travel route and surrounding objects
Solution Approach 1:
The system changes the display parameters by generating an enlarged overhead image with increased scale and adjusted perspective. This parameter transformation converts a standard overhead view into an expanded representation that emphasizes spatial relationships, making it easier for users to comprehend the positional relationships between the travel route and surrounding objects while maintaining vehicle position 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 a periphery of the travel route. The method further includes causing a display device to display the first enlarged overhead image.
