Rear-View Image Synthesis With Vehicle Outline for Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods struggle to effectively convey the relative positional relationship between a vehicle and ambient objects, making it difficult for drivers to park accurately when relying on synthetic images.
Innovation Solution
An image processing method that captures images from a first camera installed on the side surface of the vehicle and a second camera on the rear end, synthesizes these images to create a rear view of the vehicle, and superimposes an outline along the vehicle's side surface contour within the synthetic image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a synthetic image is generated by synthesizing only a rear view image, then the image processing is simple, but the driver cannot grasp the relative positional relationship between the vehicle and ambient objects
Solution Approach 1:
The patent divides the image capture system into multiple segments: a first image capturing device for capturing the rear lateral side and a second image capturing device for capturing the rear view. By segmenting the capture function across multiple devices, the system preserves comprehensive spatial information that enables drivers to grasp relative positional relationships, while each individual device maintains simple capture operations.
Solution Approach 2:
The patent transitions from a single rear view (2D perspective) to a multi-dimensional synthesis by incorporating the rear lateral side view. This dimensional expansion provides depth and lateral context, enabling drivers to understand the vehicle's spatial relationship with surrounding objects in three-dimensional space.
2Ease of operation
If a synthetic image includes the rear lateral side view, then the driver can grasp the relative positional relationship, but the image processing becomes more complex
Solution Approach 1:
The patent introduces an outline as an intermediary element that bridges the complex multi-view synthesis and the driver's perception. The outline, which represents the vehicle's side surface contour, serves as a visual mediator that simplifies the interpretation of the synthesized image, making parking operations easier without requiring the driver to mentally process complex multi-perspective spatial relationships.
3Measurement precision
If an outline is superimposed on the synthetic image, then the driver can easily grasp the vehicle boundary, but the image processing complexity increases
Solution Approach 1:
The patent employs visual differentiation through the superimposition of outlines on the synthetic image. By adding distinct visual elements (outlines) that contrast with the background image, the system enhances the detectability of vehicle boundaries. This visual enhancement technique allows drivers to quickly and accurately perceive the vehicle's spatial extent without requiring complex analytical processing.

AI summary
An image processing method includes: capturing, by a first image capturing device installed at a position located on a side surface outside a vehicle interior of a vehicle and anterior to a rear end of the vehicle, a first image, the first image being an image of a region including a rear lateral side of the vehicle; capturing, by a second image capturing device installed on a rear end of the vehicle, a second image, the second image being an image of a region in a rear of the vehicle; generating a synthetic image serving as an image of a rear view of the vehicle by synthesizing the first image and the second image with each other; and superimposing an outline, the outline being a line segment extending along a contour of a side surface of the vehicle, in the synthetic image.
