Smart Glasses Crane Control via Vision Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating industrial cranes from the floor level can be inefficient and unsafe due to the need for continuous visual attention to the load and surroundings, with challenges in managing free space, obstacles, inertia, and oscillation, and existing solutions lack intuitive and flexible control methods.
Innovation Solution
The use of smart glasses with a camera and communication link to a wireless control device for an industrial crane, enabling augmented reality data presentation and automatic steering of the crane, allowing operators to give commands without continuous gaze direction, with features like swaying control, restricted area detection, and safety area creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator continuously monitors the load and surroundings visually, then safety is improved, but operator workload and complexity of operation increase
Solution Approach 1:
The system enables automatic steering where the crane system steers itself based on detected target positions and restricted areas, eliminating the need for continuous manual control while maintaining safety through automated monitoring and navigation
Solution Approach 2:
The patent replaces manual visual monitoring and mechanical control with an automated vision-based system using cameras, image processing, and computer control algorithms to detect targets, determine positions, and automatically steer the crane
2Manufacturing precision
If manual control is used for precise positioning, then positioning precision is improved, but productivity decreases due to continuous visual attention required
Solution Approach 1:
The system replaces manual positioning control with an automated vision-based positioning system that uses camera detection, image processing, and computer algorithms to achieve precise positioning automatically, eliminating the trade-off between precision and productivity
Solution Approach 2:
The patent introduces an intermediary automated control system that acts as a mediator between the operator's intent and the crane's movement, using vision sensors and control algorithms to achieve precise positioning without requiring continuous manual intervention
3Ease of operation
If automated steering is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system uses a multi-functional integrated control platform that combines camera detection, image processing, target recognition, position calculation, and steering control in a single unified system, reducing overall complexity despite the advanced capabilities
Solution Approach 2:
The patent introduces an intermediary automated control system that acts as a mediator between the operator's intent and the crane's movement, using vision sensors and control algorithms to achieve precise positioning without requiring continuous manual intervention

AI summary
A method and equipment for detecting (210) with smart glasses (130) used by the operator (140) an target (150; 120) intended by the operator; detecting (220) a driving command given by the operator; and responsively to the detection of the driving command steering (230) the loading member (1 16) or the load (150) towards said target.
