Work Vehicle Surround Monitoring With Edge-Highlighted Obstacle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of construction machines may not consistently notice obstacles or people in their surroundings due to distractions, leading to potential safety hazards.
Innovation Solution
A safety monitoring system that includes a detection device, a display device, and a control device, which captures images and uses edge-defining processes to highlight objects in the surroundings, and emits warning sounds when necessary, to draw the operator's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera captures and displays images of the surroundings, then the operator can see obstacles or people, but the operator may not steadily look at the display device and may not notice the presence of an obstacle or a person
Solution Approach 1:
The patent applies color changes by superimposing colored outlines (e.g., red, yellow, green) on detected objects in the displayed image. Different colors indicate different levels of urgency or object types, making objects stand out visually against the background and drawing the operator's attention even when not steadily observing the display.
Solution Approach 2:
The patent changes visual parameters of detected objects by applying edge-defining processes that enhance contrast and outline visibility. The control device adjusts image parameters such as outline thickness, color intensity, and positioning based on object distance and type, making objects more noticeable without requiring the operator to maintain constant focus on the display.
2Measurement precision
If the display device shows a normal captured image, then the operator can see the surroundings, but objects may not be easily noticeable when the operator is distracted
Solution Approach 1:
The patent uses color changes to encode object information. Colored outlines are superimposed on detected objects, with different colors representing different object categories or distance zones. This color-coding system preserves detection accuracy while compensating for potential information loss due to operator distraction by making objects visually prominent.
Solution Approach 2:
The patent applies local quality enhancement by selectively processing only the regions containing detected objects. Edge-defining processes and colored outlines are applied specifically to object areas rather than the entire image, preserving detection precision while drawing localized attention to objects without overwhelming the operator with global image processing.

AI summary
A safety monitoring system includes a detection device, a display unit, and a control unit. The detection device detects an object in the surroundings of the work vehicle. The display unit displays a captured image of the surroundings of the work vehicle. The control unit controls the detection device and the display unit. If the detection device detects an object, the control unit controls the display unit to display an image with a defined edge obtained by applying an edge-defining process to the image of the surroundings.
