Remote Camera Angle Control for Working Machine Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for working machines face challenges in adjusting the image-pickup angle of cameras to accurately reflect the target object's position, especially due to varying cabin heights across different machine types, which requires time-consuming calibration and may not always provide an appropriate field of view for operators.
Innovation Solution
A remote operation processing device that acquires and stores the positions of attachments during work as target sets of coordinate values, and controls the image-pickup angle of the image-pickup device based on the distribution of these target sets, allowing for automatic adjustment to ensure an appropriate field of view for operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image-pickup angle is adjusted manually for each working machine type, then the field of view can be adapted to different cabin heights, but the adjustment process requires much time and manual calibration
Solution Approach 1:
The system automatically determines the image-pickup angle by utilizing the working machine's own state quantity data (actuator positions) to calculate and adjust the camera orientation, eliminating the need for manual calibration and making the system self-configuring
Solution Approach 2:
The system changes the image-pickup angle parameter automatically based on the state quantity of the working machine's actuators, allowing dynamic adaptation to different machine configurations without manual intervention
2Adaptability or versatility
If the image-pickup angle is adjusted based on stored actuator state quantities, then the camera field of view can be configured for different machine types, but the determined field of view is not necessarily appropriate for the operator's visual confirmation needs
Solution Approach 1:
The system uses feedback from the working machine's actual工作状态 (actuator positions) to dynamically adjust the image-pickup angle, ensuring the camera is oriented toward the actual working area rather than relying on pre-stored configurations
Solution Approach 2:
The image-pickup angle is made dynamic and adjustable based on real-time machine state, allowing the system to adapt to actual working conditions rather than being fixed to pre-stored configurations
