Vehicle Image Processing Device for Natural Parking Region Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies for vehicles struggle to display parking regions and obstacles naturally when projecting images onto a three-dimensional plane, as the projection plane's width affects the distortion of these features, leading to unnatural composite images.
Innovation Solution
An image processing device that acquires images of a vehicle's surroundings, projects them onto a stereoscopic projection plane, and adjusts the projection regions to ensure the target parking area and movement path are displayed naturally by shifting parts of the image to a planar surface projection region, while also using maps to associate coordinates and texture coordinates for efficient display processing.

1Area of stationary object
If the flat projection plane is made narrow to include the vehicle and parking region, then the parking region can be projected to the plane, but the parking frame becomes distorted and unnatural
Solution Approach 1:
The projection plane is divided into multiple regions: a first projection region (rising above the vehicle) for displaying obstacles and a second projection region (horizontal to the vehicle) for displaying the parking region and movement path. This segmentation allows each region to be optimized independently - the first region can be narrower to avoid distortion while the second region provides adequate width for natural parking region display.
Solution Approach 2:
The projection plane transitions from a traditional single flat plane to a stereoscopic projection plane with multiple regions at different heights and orientations. The first projection region rises above the vehicle in the vertical dimension, while the second projection region extends horizontally, creating a multi-dimensional projection space that resolves the contradiction between plane width and shape distortion.
2Area of stationary object
If the flat projection plane is made wide to include distant obstacles, then obstacles can be projected to the plane, but the obstacles become distorted and the composite image appears unnatural
Solution Approach 1:
The projection plane is segmented into distinct functional regions: the first projection region for obstacles and the second projection region for parking-related elements. This allows the obstacle region to be positioned and sized appropriately without being constrained by the width requirements of the parking region, thereby avoiding obstacle distortion while maintaining natural appearance.
Solution Approach 2:
Different regions of the projection plane are assigned different geometric properties and orientations suited to their specific purposes. The first projection region can have properties optimized for displaying distant obstacles naturally, while the second projection region has properties optimized for displaying the parking region and movement path, allowing each local area to have the quality it needs without compromising other areas.

AI summary
An image processing device according to an embodiment exemplarily includes, as an example: a processor that acquires a taken image obtained by imaging surroundings of a vehicle by an imaging unit mounted on the vehicle; projects the taken image to a stereoscopic projection plane including the vehicle and a first projection region rising above the vehicle and produces a composite image of the stereoscopic projection plane when viewed from a virtual viewpoint; causes a display to display the composite image; determines a target parking region in which the vehicle is parked in the stereoscopic projection plane; and shifts at least a part of a movement path of the vehicle from a position of the vehicle to the target parking region and the target parking region of the vehicle to a second projection region horizontal to the vehicle.
