Vehicle Image Processor Smooth Virtual Line of Sight Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle image processing systems cause abrupt changes in the viewed image when the virtual line of sight is altered, making it difficult for drivers to promptly grasp the surrounding environment after a change in viewing perspective.
Innovation Solution
A vehicle image processing apparatus that includes image acquisition, projection conversion, line-of-sight change detection, parameter generation, and image generation means to smoothly transition between different virtual line of sights by interpolating parameter values such as visual point position and viewing direction, ensuring a gradual change in the displayed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the virtual line of sight is changed to provide different viewing perspectives, then the driver can view different areas around the vehicle, but the image changes abruptly making it difficult to grasp the situation
Solution Approach 1:
The patent implements dynamic transition between different virtual line of sight perspectives by continuously interpolating the viewpoint position and direction parameters. Instead of switching between fixed discrete views, the system dynamically adjusts the viewing parameters over time, creating a smooth animated transition that helps the driver's visual system adapt to the changing perspective while maintaining situational awareness.
Solution Approach 2:
The patent introduces an intermediate transition state between different viewing perspectives. Rather than directly switching from one line of sight to another, the system generates intermediate viewpoints that gradually bridge the gap between the initial and target perspectives. This intermediary approach creates a continuous visual narrative that helps the driver understand the spatial relationship between different views.
2Area of stationary object
If the viewing position or direction changes significantly, then a different area can be observed, but the sudden change causes disorientation for the driver
Solution Approach 1:
The system dynamically adjusts the viewing parameters (position and direction) over time rather than making sudden static changes. By continuously updating the viewpoint along an interpolated path, the observable area expands gradually while the driver's visual system adapts to the changing perspective, preventing disorientation caused by abrupt transitions.
Solution Approach 2:
The patent applies beforehand cushioning by preparing intermediate transition states before the final viewpoint change is complete. The system anticipates the driver's need for visual adaptation and provides gradual transitional images that cushion the impact of significant viewing changes, reducing the harmful disorientation effect while still achieving the desired observable area expansion.

AI summary
Provided is a vehicle image processing apparatus including: a group of cameras 8 that capture an area around a vehicle; a drawing unit 20 that converts a captured image into an image viewed along a virtual line of sight which is a line of sight running from a predetermined position in a predetermined direction; a viewing-line-of-sight changing unit 4 that detects whether a first virtual line of sight which is a predetermined virtual line of sight is switched to a second virtual line of sight which is different from the first virtual line of sight; and a viewing-line-of-sight generation/updating unit 5 that acquires parameters concerning the first and second virtual lines of sight after detecting the switching and generates a parameter which is gradually changed from the parameter of the first virtual line of sight to the parameter of the second virtual line of sight. Moreover, the drawing unit 20 generates, on the basis of the gradually changed parameter value, a changed image which is gradually changed from an image viewed along the first virtual line of sight to an image viewed along the second virtual line of sight.
