Vehicle Surround-View Imaging With Adaptive Image Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies for vehicles do not adequately control the display format of vehicle images combined with surrounding views from a virtual viewpoint, affecting the accuracy of understanding the vehicle's surroundings.
Innovation Solution
An image processing device that generates composite images by combining vehicle and surrounding views from virtual viewpoints, with controls for rotating the viewpoints in predetermined patterns or user-defined movements, and adjusts the vehicle image transparency based on the control type.

Engineering Contradiction Analysis
1Device complexity
If a single fixed transmittance value is used for the vehicle image, then the system complexity is reduced, but the adaptability to different operational purposes deteriorates
Solution Approach 1:
The system transitions from a static, fixed transmittance value to a dynamic, adjustable transmittance that responds to different operational modes. This allows the same vehicle image display system to adapt to multiple purposes (automatic rotation display and manual positioning display) without increasing overall system complexity, as the transmittance adjustment is automatically managed based on the current mode.
Solution Approach 2:
The vehicle image display system achieves multi-functionality by using a single adjustable transmittance parameter to serve different operational purposes. The same display mechanism can effectively support both automatic rotation mode (where surrounding visibility is prioritized) and manual positioning mode (where vehicle image clarity is prioritized), enhancing adaptability without requiring separate systems.

AI summary
An image processing device includes: a processor configured to generate a surrounding image when a vehicle is viewed from a virtual viewpoint, based on captured images, generate a composite image in which a vehicle image showing the vehicle when viewed from the virtual viewpoint is combined with the surrounding image, and display the composite image on a display device. The processor is configured to: perform a first control for displaying the composite image on the display device while rotationally moving the virtual viewpoint with respect to the vehicle in a predetermined pattern, and a second control for displaying the composite image on the display device while moving the virtual viewpoint to a position according to an operation of an operation unit of the vehicle; and change a transmittance of the vehicle image when performing the first control and when performing the second control.
