Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines face challenges in accurately determining the positional relationship between the machine and its surroundings, which affects navigation and operational efficiency, especially when passing through narrow spaces.
Innovation Solution
A system comprising cameras, a processor, and a display that captures and synthesizes images of the work machine's surroundings, generating a guide display with lateral and vehicle width guide lines to provide real-time visual feedback on the machine's position relative to its environment, allowing operators to navigate more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional camera system is used to capture surroundings images, then the system structure is simple, but the operator cannot accurately ascertain the positional relationship between the work machine and the surroundings
Solution Approach 1:
The patent introduces guide lines that extend in the vehicle width direction (lateral dimension) overlaid on the bird's-eye view image. This adds a dimensional reference system that helps operators perceive width-directional positional relationships that are otherwise difficult to judge from a top-down perspective alone, thereby improving measurement precision of positional relationships without requiring additional physical sensors or cameras.
Solution Approach 2:
The guide lines act as an intermediary visual element between the camera system and the operator's perception. These virtual reference lines provide a mediating framework that translates the complex spatial information from multiple cameras into intuitive width-directional distance indicators, enabling accurate positional assessment without increasing the physical sensor system complexity.
2Measurement precision
If multiple cameras are used to capture comprehensive surroundings images, then the measurement precision of positional relationship is improved, but the device complexity increases
Solution Approach 1:
The guide lines add a lateral dimension reference system to the existing bird's-eye view images from multiple cameras. This visual overlay provides width-directional positional information without requiring additional cameras or sensors, thus improving measurement precision while avoiding increased device complexity.
Solution Approach 2:
The guide lines are virtual copies or representations of the vehicle width boundaries overlaid on the image display. These graphical copies provide reference information that complements the actual camera data, enabling improved positional relationship measurement without adding physical hardware complexity.
