Adaptive Bird's-Eye View Display for Vehicle Exit Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle periphery display systems do not effectively provide a bird's-eye view when exiting a parking space, leading to inadequate peripheral state monitoring, especially when changes in the peripheral condition occur, such as increased adjacent vehicles or altered visibility.
Innovation Solution
A display control system that acquires video data from multiple cameras, generates a bird's-eye view video through viewpoint conversion and synthesis processing, and selectively displays it when the peripheral checking condition changes upon exiting a parking space, using sensors to detect changes in adjacent vehicles and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bird's-eye view video is displayed when the vehicle moves forward to exit the parking space regardless of the peripheral state, then the driver can always check the peripheral state with the bird's-eye view video, but the bird's-eye view video is unexpectedly displayed when it need not be displayed, causing unnecessary distraction and reducing ease of operation
Solution Approach 1:
The system dynamically adjusts the display control based on real-time peripheral state changes. The display controller determines whether to display the bird's-eye view video by comparing current peripheral state information with stored reference information, making the display adaptive rather than static. This resolves the contradiction by making the system responsive to actual needs while avoiding unnecessary displays.
Solution Approach 2:
The system uses feedback from the peripheral state detection to control the display. The display controller receives feedback about changes in peripheral state (such as changes in adjacent vehicles, pedestrians, or obstacles) and adjusts the bird's-eye view video display accordingly. This feedback mechanism ensures the video is displayed only when peripheral conditions have changed, maintaining reliability while avoiding unnecessary distraction during normal exits.
2Ease of operation
If the bird's-eye view video is not displayed when the vehicle moves forward to exit the parking space, then the system avoids unnecessary display, but the peripheral state is inadequately monitored when changes occur such as increased adjacent vehicles or altered visibility
Solution Approach 1:
The system performs preliminary detection and comparison of peripheral state information before determining whether to display the bird's-eye view video. The display controller stores reference peripheral state information when the vehicle enters the parking space and compares it with current peripheral state information upon exit. This preliminary action ensures that changes in peripheral conditions are detected and addressed appropriately, preventing information loss while maintaining ease of operation during normal exits.
Solution Approach 2:
The system implements feedback by continuously monitoring peripheral state changes and using this information to control the display. When the comparison between current and reference peripheral state information indicates changes (such as new adjacent vehicles or visibility alterations), the system provides feedback to activate the bird's-eye view video display, ensuring critical information is not lost while avoiding unnecessary displays during unchanged conditions.
3Reliability
If the bird's-eye view video is displayed during forward exit from parking space, then peripheral state can be checked, but the display may interfere with route checking using navigation system
Solution Approach 1:
The system dynamically controls the bird's-eye view video display based on detected peripheral state changes rather than displaying it continuously during forward exit. By activating the display only when changes in peripheral conditions (such as new obstacles or visibility changes) are detected, the system maintains peripheral checking reliability while minimizing interference with navigation system route checking during normal, unchanged exits.
Data Source
AI summary
A display control device includes a video data acquiring unit that acquires video data from a plurality of cameras photographing a periphery of a vehicle, a bird's-eye view video generator that applies view point conversion processing and synthesis processing to the video data to generate a bird's-eye view video, an adjacent information acquiring unit that acquires first obstacle information serving as information about obstacles around the vehicle when the vehicle has moved backward and entered the parked state, and second obstacle information serving as the information about the obstacles around the vehicle when the vehicle moves forward to exit the parked state, a comparing unit that compares the first obstacle information with the second obstacle information to determine whether the number of obstacles around the vehicle has increased when the vehicle exits the parked state, and a display controller.
