Work Machine Display Screen Segmentation for Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines, such as excavators, face challenges in visually confirming the surrounding situation during calibration processes, which is crucial for precise operation and safety.
Innovation Solution
A display device equipped with a display control unit that utilizes image data from cameras installed on the work machine to display a calibration screen showing both surrounding situation data and calibration data, enabling operators to visually confirm the environment and perform calibration tasks effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device shows calibration data during calibration process, then calibration information is provided to the operator, but the surrounding situation information is not displayed, making it difficult for the operator to visually confirm the environment
Solution Approach 1:
The display screen is divided into multiple independent display regions: a first display region dedicated to showing surrounding situation information from camera images, and a second display region for presenting calibration data and instructions. This segmentation allows both types of information to be displayed simultaneously without interfering with each other, resolving the contradiction between providing complete information and maintaining display simplicity.
2Reliability
If the display screen shows only calibration data, then calibration instructions are clear, but the operator cannot visually confirm the surrounding situation during calibration
Solution Approach 1:
The patent merges the surrounding situation display function with the calibration data display function into a single unified display interface. The first display region shows real-time camera images of the work machine's surroundings, while the second display region presents calibration instructions and status. This combination allows operators to perform calibration tasks with the same ease as before while simultaneously monitoring the surrounding environment, thereby improving operational safety without compromising ease of operation.
Data Source
AI summary
A display device for a work machine includes a display control unit that, based on image data obtained by a camera installed in the work machine, displays a calibration screen including surrounding display data which indicates the surrounding situation of the work machine, and calibration display data which is used in the calibration of the work machine.
