Parking Display View Switching Using Image-Based Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle camera systems require manual input from drivers to switch between camera views during parking maneuvers, which is distracting and may lead to errors due to the need to focus on multiple views simultaneously.
Innovation Solution
A processor-controlled system that automatically selects camera views based on the vehicle's location, status, and maneuver, using image-based localization and pre-configured user preferences to minimize driver interaction and provide accurate information without distractions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used to switch camera views, then driver control over view selection is maintained, but driver distraction and error risk increase during parking maneuvers
Solution Approach 1:
The system automatically selects and switches camera views based on detected parking maneuvers and vehicle state, eliminating the need for manual driver input. The system serves itself by monitoring sensors and autonomously controlling display content, thereby maintaining driver control through automation while eliminating distraction.
Solution Approach 2:
The mechanical button-pressing interface is replaced with an automated sensor-based system that detects parking maneuvers and automatically switches views. This substitution eliminates the need for mechanical interaction, replacing it with automated electronic control that responds to vehicle state and maneuver detection.
2Loss of information
If multiple camera views are displayed simultaneously, then comprehensive maneuver information is provided, but driver cognitive load and distraction increase
Solution Approach 1:
The display dynamically adapts its content based on the detected maneuver phase and vehicle state. Instead of showing multiple static views simultaneously, the system dynamically switches between different single views that are most relevant at each moment, providing comprehensive information coverage without constant multi-view complexity.
Solution Approach 2:
Different display regions or views are optimized for specific maneuver phases. The system provides locally optimized view quality by selecting the most appropriate single camera view for the current maneuver stage, rather than uniformly displaying all views throughout the entire maneuver.
3Reliability
If view switching is automated based on location and maneuver detection, then driver distraction is reduced, but system complexity and processing requirements increase
Solution Approach 1:
The system pre-defines maneuver phases and associated optimal views based on vehicle state and location data. By preparing view selection strategies in advance for different maneuver scenarios, the system reduces real-time processing complexity while maintaining automated safety-driven view switching.
Solution Approach 2:
The system uses a unified automated control mechanism that handles multiple functions: detecting parking maneuvers, determining vehicle state, selecting appropriate views, and controlling display switching. This multi-functional approach consolidates complexity into a single integrated system rather than separate components for each function.

AI summary
An apparatus includes an interface and a processor. The interface may be configured to receive pixel data corresponding to an exterior view from a vehicle. The processor may be configured to (a) process the pixel data arranged as video frames, (b) generate video data for a display in response to the video frames, (c) store a plurality of view preferences for the display, (d) determine (i) a current location of the vehicle, (ii) a current status of the vehicle, (iii) a current maneuver being performed, and (iv) which portion of the current maneuver is being performed, and (e) generate an output signal to select a view for the display. Each view preference generally corresponds to one or more of (i) a location, (ii) a vehicle status, (iii) a maneuver, and (iv) a portion of the maneuver, when the maneuver comprises more than one portion. The processor may switch between a plurality of view preferences associated with the maneuver based on a plurality of precise locations corresponding to a plurality of portions of the maneuver. The processor may determine a current precise location within the maneuver by calculating distances using image-based localization applied to the video frames. The output signal may be generated in response to the current precise location within the maneuver and the current status matching the precise location and the vehicle status, respectively, of a particular one of the plurality of view preferences corresponding to the plurality of portions of the maneuver. The view selected may be determined based on the particular one of the plurality of view preferences.
