Blind Spot Display System Using Camera and GPS Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in safely navigating and parking vehicles due to blind spots hidden by the vehicle body, which are not within their field of view, leading to potential collisions with obstacles.
Innovation Solution
An apparatus and method that uses cameras, GPS navigation, and external information reception to display images of the vehicle's surroundings, including blind spots, by outputting captured images and vehicle icons on a screen, allowing drivers to visualize and navigate around obscured areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver relies on the natural field of view, then the driving operation is simple, but the blind spots cannot be detected leading to collision risks
Solution Approach 1:
The patent introduces a display unit as an intermediary between the driver and the blind spot area. The display unit presents processed images showing the blind spot region, allowing the driver to detect obstacles without directly viewing them. This mediator bridges the gap between the driver's limited field of view and the need for comprehensive situational awareness.
Solution Approach 2:
The system creates a visual copy of the blind spot area by capturing images with cameras positioned to view regions not visible to the driver. These copied images are then processed and displayed, allowing the driver to perceive obstacles in areas they cannot directly observe, effectively replicating visual information from inaccessible regions.
2Reliability
If the driver raises head to check front and rear portions, then obstacle detection improves, but parking difficulty increases due to limited field of view
Solution Approach 1:
The display unit serves as an intermediary that provides continuous visual information about the front and rear blind spots without requiring the driver to physically move their head. This allows the driver to maintain a normal seating position while still accessing information about obstacles in areas they would otherwise need to directly observe.
Solution Approach 2:
The system performs preliminary detection and presentation of blind spot information, preparing visual data about potential obstacles before the driver needs to make parking decisions. This advance provision of information allows the driver to plan parking maneuvers with better awareness of the environment.
3Productivity
If the driver focuses on driving, then driving efficiency improves, but temporary memory of obstacles is lost leading to collision risk
Solution Approach 1:
The system provides continuous feedback about obstacles in the blind spot area through the display unit. This ongoing visual feedback reinforces the driver's awareness of obstacles without requiring active attention or memory retention. The feedback loop maintains situational awareness passively, allowing the driver to focus on primary driving tasks while remaining informed about potential hazards.

AI summary
An apparatus and method for displaying a blind spot, which involve displaying at least one image of the surroundings of a vehicle, in which the image is provided by an imaging unit including a camera, a GPS navigation system, and/or a street-view receiver, so as to provide a driver with information on the blind spots of a front portion, a rear portion, and a side portion of a vehicle that are hidden by the vehicle and thus not easily seen within the field of view of the driver during travel of the vehicle.
