Shovel Camera Display Alerts for Off-Screen Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing shovel systems, if a monitoring object is detected outside the range of the peripheral image displayed on the display device, it may not be displayed, leading to the operator's inability to identify the location around the shovel.
Innovation Solution
A display device that displays an image captured by a first camera representing the situation around a shovel and alerts the operator when a predetermined object is detected outside the imaging range of a second camera, ensuring the operator is aware of the object's presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device only shows images within the first camera's imaging range, then the display simplicity is maintained, but the operator cannot identify objects outside the displayed range
Solution Approach 1:
The patent divides the monitoring system into multiple cameras with different imaging ranges. The first camera provides the main displayed image, while the second camera monitors a broader area. This segmentation allows the system to track objects in multiple zones without displaying all information simultaneously, resolving the contradiction between complete information and display simplicity.
Solution Approach 2:
The system implements feedback by notifying the operator when the second camera detects objects outside the first camera's imaging range. This feedback mechanism ensures the operator is informed about objects beyond the current display without requiring constant display of all sensor data, thus maintaining simplicity while preventing information loss.
2Reliability
If multiple cameras are used to expand monitoring coverage, then the detection capability is improved, but the system complexity increases
Solution Approach 1:
The monitoring function is segmented between two cameras: the first camera for primary imaging within its range, and the second camera for extended range detection. This segmentation improves detection reliability by covering more areas while keeping each camera's function simple and well-defined, preventing excessive system complexity.
Solution Approach 2:
The second camera serves a dual purpose: it monitors areas beyond the first camera's range and provides feedback when objects are detected outside the primary imaging range. This multi-functionality improves detection reliability without proportionally increasing system complexity, as one camera performs multiple monitoring roles.

AI summary
A display device is provided. The display device displays an image captured by a first camera of a plurality of cameras, the captured image representing a situation around a shovel, and when a predetermined object is detected within an imaging range of a second camera that is different from the first camera, the display device displays an image representing that the predetermined object is detected outside a range of the displayed captured image of the first camera.
