Construction Machinery Camera Tracking for Bucket Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for construction machinery, such as excavators, suffer from reduced visibility of the bucket during operation due to its deviation from the image center, leading to operator discomfort and decreased workability and stability.
Innovation Solution
A control system that includes a camera installed in the work apparatus to capture the working area, an image processing device to recognize the shape of the attachment (e.g., bucket) and perform a tracking image process to keep it centered in the image, and a display device to show the processed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is fixedly installed on a boom or arm to provide an image of the working area, then the operator can see the working area, but the bucket is displayed at a position deviated from the center of the image due to rotation angle changes, causing operator discomfort and reduced workability
Solution Approach 1:
The system continuously monitors the position of the bucket in the camera image and uses this feedback to dynamically adjust the image processing. The processor calculates the deviation of the bucket from the center and applies real-time image transformation to correct the position, creating a closed-loop control system that maintains optimal visibility throughout operation.
Solution Approach 2:
The image processing system dynamically adapts to changing operating conditions by continuously tracking the bucket's movement and adjusting the image transformation parameters accordingly. This dynamic processing ensures the bucket remains centered in the display regardless of boom or arm rotation angles, transforming a static camera system into a dynamically adaptive visualization system.
2Device complexity
If the camera is fixedly installed to capture the working area, then the system structure is simple, but the bucket position deviates from the image center during operation, reducing visibility
Solution Approach 1:
The image processing device acts as an intermediary between the fixed camera and the display, transforming the raw camera image to compensate for the fixed installation's limitations. This intermediary processing layer corrects the bucket's position without requiring physical repositioning of the camera, maintaining structural simplicity while improving visibility.
Solution Approach 2:
The system creates a transformed copy of the original camera image that corrects the bucket's position. Instead of physically moving the camera or bucket, the system generates a corrected visual copy where the bucket appears centered, allowing the physical system to remain simple while the visual representation is optimized.

AI summary
A control system for construction machinery includes a camera installed in a work apparatus to photograph a working area in which the work apparatus works, an image processing device configured to recognize a shape of an attachment of the work apparatus in an image captured by the camera and perform a tracking image process on the image such that the attachment is displayed in a central region of the image, and a display device configured to display the tracking image-processed image.
