Solution Overview
Problem
Engineering machinery, particularly with hinged structures, faces challenges in providing a comprehensive view of its surroundings due to blind spots caused by shielding objects and the changing angles of hinged segments, which complicates steering and safety during operation.
Innovation Solution
A panoramic surround-view system with multiple photographing devices mounted on hinged structure segments, an image processing device for splicing images into a 360° view, and calibration devices to correct distortions, ensuring a clear and comprehensive environmental view without the need for angle sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple photographing devices are mounted on hinged structure segments to eliminate blind spots, then the field of view and safety are improved, but the device complexity increases
Solution Approach 1:
The hinged engineering machinery is divided into multiple hinged structure segments, with photographing devices mounted on each segment. This segmentation allows each device to capture images of different areas, and when combined, provides a complete surround view that eliminates blind spots while managing the complexity through modular distribution of sensors.
Solution Approach 2:
The system transitions from traditional 2D rear-view mirror displays to a 360-degree three-dimensional surround view by mounting photographing devices on multiple hinged segments. This dimensional change allows comprehensive coverage of the environment around the machinery, eliminating blind spots through spatial distribution of viewing angles.
2Measurement precision
If photographing devices are mounted on hinged structure segments to track moving parts, then the measurement precision of hinged segment positions is improved, but the device complexity increases
Solution Approach 1:
The photographing devices serve dual functions: they capture images for the surround view display and simultaneously track the position and movement of the hinged structure segments. This self-service approach eliminates the need for separate angle sensors or measurement devices, reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The photographing devices are designed to perform multiple functions: capturing environmental images for safety monitoring and simultaneously measuring the position and orientation of hinged segments. This multi-functionality reduces the total number of components needed, lowering device complexity while achieving precise measurement of hinged segment positions.
3Ease of operation
If a panoramic surround-view system is implemented to provide comprehensive environmental view, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system merges the functions of multiple photographing devices mounted on different hinged segments into a single integrated panoramic surround-view display. By combining images from all segments and processing them through an image processing device, the system provides a unified comprehensive view that simplifies operator decision-making and improves ease of operation despite the underlying complexity of multiple sensors.
