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 this image to the user, allowing them to visualize the travel route and its surroundings.

1Extent of automation
If conventional parking assist technology is used to enable autonomous driving based on teacher driving, then the vehicle can automatically park in fixed positions, 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 overhead view image that replicates the spatial relationships between the travel route, objects, and roads. This virtual representation allows users to objectively understand the positional relationships without directly observing the physical environment during autonomous operation.
Solution Approach 2:
The system transforms the three-dimensional spatial relationships in the physical world into a two-dimensional overhead view representation. By projecting the travel route and surrounding objects onto a top-down plane, the system enables users to comprehensively understand positional relationships that would be difficult to perceive from ground-level perspectives during autonomous driving.
2Loss of information
If detailed captured images are processed to generate comprehensive overhead images, then user understanding of the environment is improved, but processing time and computational resources increase
Solution Approach 1:
The system extracts only the essential information needed for user understanding from the captured images - specifically focusing on identifying the travel route, surrounding objects, and road structures. By extracting only these critical elements rather than processing all image data, the system reduces computational burden while maintaining the ability to generate comprehensive overhead views.
Solution Approach 2:
The system performs preliminary processing of captured images during the teacher driving phase to pre-generate overhead view images. This advance preparation allows the processed images to be ready for immediate display during autonomous parking operations, eliminating the need for real-time processing and thus reducing time loss during critical parking maneuvers.

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.
