Vehicle Surround View Indicators for Static Hazard Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing periphery monitoring devices struggle to effectively notify users of static objects around a vehicle, as static frames do not convey movement or changes in object position, making it difficult for drivers to recognize potential hazards.
Innovation Solution
A periphery monitoring device that acquires images from multiple imaging units and radars, generating a bird's-eye view image with indicators that change display modes over time, such as moving contour lines or virtual three-dimensional objects, to highlight attention areas and improve recognition of moving or stationary objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame enclosing the object is displayed to notify the user of the existence of the object, then the user is notified of the object's presence, but when the object does not move, the frame continues to be displayed in the same way making it difficult for the user to recognize the object
Solution Approach 1:
The patent applies the Dynamics principle by making the frame dynamic rather than static. The frame rotates around the detected object, changing its orientation continuously. This rotation creates visual movement that draws the driver's attention to stationary objects, solving the problem of poor object recognition while maintaining reliable notification of object presence.
2Device complexity
If a static frame is used to indicate object position, then the display is simple and clear, but the user cannot distinguish between moving and stationary hazards
Solution Approach 1:
The patent uses dynamic frame rotation to encode object movement status. Stationary objects are indicated by rotating frames, while moving objects can be distinguished by the interaction between the rotating frame and the object's actual movement. This maintains relatively simple display structure while conveying additional information about object status.
Solution Approach 2:
The frame rotates periodically around the object, creating a rhythmic visual pattern. This periodic motion helps draw attention to the object's location and provides a clear visual signal that distinguishes detected objects from the background environment, while the rotation itself can indicate whether the object is stationary or moving.

AI summary
A periphery monitoring device includes: an acquisition unit configured to acquire a captured image from an imaging unit that captures an image of a periphery of a vehicle and positional information regarding an attention area set around the vehicle; and a controller configured to superimpose and display an own vehicle image showing a position of the vehicle and an indicator indicating a position of the attention area based on the positional information on a peripheral image as a bird's-eye view image based on the captured image, and to perform display such that a display mode of the indicator changes over time.
