Work Machine Guide Line Synthesis for Positional Accuracy
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 hinders efficient operations like excavating, as existing systems do not provide clear and precise visual feedback.
Innovation Solution
A system comprising cameras, sensors, and a processor that captures and synthesizes images of the surroundings, generating a guide line to indicate the shape of the environment, allowing operators to view the work machine's position relative to its surroundings on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a bird's-eye view image is synthesized from multiple cameras, then the operator can check the surroundings of the work machine, but the operator cannot accurately ascertain the positional relationship between the work machine and the surroundings
Solution Approach 1:
The patent introduces guide lines as an intermediary element that mediates between the bird's-eye view image and the actual surroundings. These guide lines are superimposed on the image at positions corresponding to the actual ground features, serving as a visual reference that helps the operator accurately understand the positional relationship between the work machine and the surroundings without requiring direct measurement or complex processing
Solution Approach 2:
The patent creates a visual copy of the actual ground features by displaying guide lines that replicate the shape and position of terrain features (such as ridges and valleys) directly on the bird's-eye view image. This copying approach allows the operator to see both the real-time camera image and the reference ground features simultaneously, enabling accurate positional assessment
2Productivity
If visual feedback is provided to show surroundings, then work efficiency can be improved, but the clarity and precision of visual feedback is insufficient
Solution Approach 1:
The patent merges multiple types of visual information into a single composite display: the bird's-eye view image from cameras, the guide lines representing ground features, and the position of the work machine. By combining these elements in one view, the system provides comprehensive visual feedback that enhances work efficiency while maintaining clarity and precision
Solution Approach 2:
The patent uses different colors to distinguish various elements in the visual feedback: the guide lines are displayed in a color that contrasts with the bird's-eye view image, and the work machine position is indicated with distinct coloring. This color differentiation helps the operator quickly and accurately interpret the visual information without confusion
Data Source
AI summary
A system includes a processor and a display. The processor acquires shape data indicative of a shape of the surroundings in a traveling direction of a work machine. The processor generates a guide line. The guide line is disposed spaced from the work machine. The guide line indicates the shape of the surroundings in the traveling direction of the work machine. The processor synthesizes a surrounding image and the guide line and generates an image including the surroundings image and the guide line. The display displays the image including the surroundings image and the guide line based on a signal from the processor. The system may further include the work machine, a camera that captures the surrounding image, and a sensor that measures the shape of surroundings.
