Vehicle Image Processing Apparatus for Parking Direction Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems for vehicles struggle to accurately display the difference in traveling direction before and after turning the wheel during parking, making it difficult for drivers to adjust the vehicle's position correctly.
Innovation Solution
An image processing apparatus that acquires images from multiple cameras, generates a support image by superimposing a trace line showing the vehicle's past path and a prediction line on the photographic image, and displays this image on a display apparatus, allowing drivers to visualize the change in direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only a guiding line is displayed to show vehicle width and traveling direction, then the display system remains simple, but the driver cannot grasp the difference in traveling direction before and after turning the wheel
Solution Approach 1:
The patent segments the vehicle's movement information into two distinct visual components: a trace line showing the past movement path and a prediction line showing the predicted movement path. This segmentation allows the driver to separately view the before and after traveling directions, clearly grasping the direction difference without overwhelming complexity in the display system.
Solution Approach 2:
The patent performs preliminary processing by deriving the trace line from past vehicle movement data before the driver needs to make a decision. This pre-computed trace line is then overlaid on the camera image, providing the driver with advance information about the direction change that will occur when turning the wheel, enabling better parking control.
2Reliability
If the driver turns the wheel to adjust parking position without visual feedback on direction change, then the operation remains simple, but the vehicle may move to the same position repeatedly
Solution Approach 1:
The patent implements visual feedback by displaying both the trace line (past path) and prediction line (future path) on the camera image. When the driver turns the wheel, they can immediately see the predicted change in traveling direction through the prediction line, providing feedback that prevents repeated adjustments and ensures accurate parking position achievement.
Solution Approach 2:
The system performs preliminary calculation of the prediction line showing where the vehicle will travel after the wheel is turned. This preliminary visualization of the future path allows the driver to anticipate the outcome of their steering action before executing it, preventing wasted time on incorrect adjustments.

AI summary
An image processing apparatus that processes an image includes an image processor configured to: acquire a photographic image from a camera photographing a region near a host vehicle; derive a trace line showing a moving trace of a path on which the host vehicle has moved previously; derive a prediction line showing a predicted moving path of the host vehicle; generate a support image by superimposing the trace line and the prediction line on the photographic image when a wheel of the host vehicle is turned; and output the support image to a display apparatus that displays the support image.
