3D Video System for Vehicle Blind Spot Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current on-vehicle display systems, including rear-view mirrors, astern-running radar, and video systems, suffer from blind spots and inaccurate distance perception due to two-dimensional image displays, which can compromise driving safety, especially during evening driving and astern-driving operations.
Innovation Solution
An on-vehicle three-dimensional video system comprising cameras positioned in pairs to capture the surrounding environment from different angles, a control module for processing and transmitting video information, and a display screen to provide a realistic three-dimensional output, allowing drivers to accurately assess distances and prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional images are displayed on the screen, then the system structure is simple, but the distance perception accuracy deteriorates
Solution Approach 1:
The patent transitions from two-dimensional image display to three-dimensional video display by using multiple cameras positioned at different locations to capture spatial information from multiple dimensions. This dimensional enhancement allows the display system to present depth and distance information realistically, resolving the contradiction between simple system structure and accurate distance perception.
2Device complexity
If single camera is used for filming, then the device complexity is low, but the blind area coverage increases
Solution Approach 1:
The patent divides the surveillance task into multiple segments by deploying several cameras at different positions around the vehicle. Each camera covers a specific field of view, and together they provide comprehensive coverage of the surrounding environment, eliminating blind spots while maintaining manageable device complexity through modular camera units.
Solution Approach 2:
The patent combines the footage from multiple cameras into a unified three-dimensional video display, merging individual camera views into a comprehensive spatial representation. This integration allows the system to cover blind areas effectively while presenting a cohesive visual information to the driver.
3Area of stationary object
If rear-view mirrors are used, then the field of view is expanded, but blind spots and dazzled feeling occur
Solution Approach 1:
The patent replaces the optical reflection mechanism of traditional rear-view mirrors with an electronic video capture and display system. Multiple cameras electronically capture images from various angles and display them on screens within the vehicle, eliminating the physical limitations of mirror reflection including blind spots and glare from headlights while providing adjustable and customizable viewing angles.

AI summary
An on-vehicle three-dimensional video system is provided for a vehicle and a method is provided for monitoring a surrounding environment of a vehicle. The on-vehicle three-dimensional video system includes, but is not limited to cameras, a display screen, a control module, and a power supply device. The cameras are provided in pairs for filming the surrounding environment of the vehicle from different angles, and the display screen is able to bring about a three-dimensional video effect according to pairs of video signals from the cameras. With the on-vehicle three-dimensional video system, a realistic three-dimensional output of the surrounding environment of the vehicle is realized on the display screen so that the driver can clearly know about the precise relative position of a corresponding portion of the vehicle with respect to the surrounding environment.
