Solution Overview

Problem

Surround view monitoring systems for vehicles face issues with image distortion due to super-wide-angle lenses and the need to display only partial images based on driving situations, which can distract drivers and obstruct their concentration.

Innovation Solution

A system comprising multiple cameras, an image synthesizer, a driving recognizer, and a display controller that captures images around the vehicle, synthesizes them, and selectively displays either partial or full images based on driving-state information, such as gear-shifting mode, speed, and obstacle detection, to focus the driver's attention on critical areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a super-wide-angle lens with a field of view of 180 degrees or greater is used to capture the entire region around the vehicle, then the coverage area is improved, but image distortion occurs and parking lines are seriously bent

Engineering Contradiction:
Improvecoverage areaVSAvoidimage distortion
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent divides the surround view monitoring system into multiple camera units, each with a narrower field of view (e.g., 60-90 degrees). Multiple cameras are strategically positioned at different locations around the vehicle (front, rear, left, right) to collectively capture the entire surrounding area. This segmentation approach eliminates the need for extreme wide-angle lenses, thereby reducing image distortion while maintaining comprehensive coverage through image synthesis.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If the entire synthesized image is displayed to provide complete surround view information, then the monitoring coverage is improved, but driver concentration is obstructed

Engineering Contradiction:
Improvemonitoring coverageVSAvoiddriver concentration
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements a dynamic display control system that adapts the displayed image content based on real-time driving conditions. The control unit receives driving state information (such as gear position, vehicle speed, steering angle) and automatically adjusts whether to display the full synthesized image or only specific regions of interest. For example, when the vehicle is stationary or moving slowly, the full surround view is displayed; when moving at higher speeds, only critical areas are shown. This dynamic adjustment maintains comprehensive monitoring capability while preventing driver distraction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different display strategies to different regions of the synthesized image based on their relevance to current driving conditions. Instead of uniformly displaying the entire surround view, the system identifies and emphasizes locally important areas (such as rear view when reversing, or side views when parking) while minimizing or hiding less relevant regions. This selective display approach ensures drivers receive critical information without being overwhelmed by unnecessary visual data.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If image synthesis technology is used to correct distortion, then image quality is improved, but system complexity increases

Engineering Contradiction:
Improveimage qualityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent employs image synthesis technology that creates a virtual bird's-eye view by computationally processing and merging images from multiple cameras. Rather than using complex optical systems to physically correct distortion, the system captures raw images from multiple angles and uses software algorithms to synthesize a corrected, distortion-free composite image. This copying approach (creating a virtual representation) achieves high image quality with relatively simple camera hardware and standard image processing techniques.

Inventive Principle:
Principle #26Copying
