3D Excavator Guidance Control for Survey-Free Precise Digging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction machinery, such as excavators, face limitations in working speed and accuracy due to the need for manual surveying and separate input of design drawing data for precise excavation, which can be time-consuming and inefficient.
Innovation Solution
A control system equipped with a 3D camera, position information receiving device, and data processing device that recognizes surrounding objects and spaces, converts relative coordinates into three-dimensional coordinates, and displays this information on a screen, allowing for precise machine guidance and control without the need for manual surveying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If 3D machine control technology is used to enable precise excavation work, then manufacturing precision is improved, but productivity deteriorates due to requiring input of design drawing data in advance and showing only drawing and shape through separate display
Solution Approach 1:
The patent combines the 3D camera, image recognition module, coordinate conversion module, and display into an integrated system that simultaneously captures spatial information, processes coordinates, and provides visual guidance. This merging eliminates the need for separate surveying processes and design drawing inputs, thereby improving productivity while maintaining excavation precision through real-time 3D spatial recognition and coordinate transformation.
2Manufacturing precision
If manual surveying and guide line installation are used for construction machinery to work accurately, then manufacturing precision is improved, but productivity deteriorates due to time-consuming manual processes
Solution Approach 1:
The patent replaces manual surveying and guide line installation with an automated 3D camera-based recognition system. The image recognition module automatically identifies guide lines and extracts coordinate information from captured images, eliminating the need for manual measurement and physical guide line installation. This substitution maintains work accuracy through precise coordinate extraction while significantly improving productivity by removing time-consuming manual processes.
3Productivity
If 3D camera and image recognition are used to recognize surrounding space, then productivity is improved by eliminating manual surveying, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent implements a multi-functional integrated system where the 3D camera serves multiple purposes: capturing spatial information, identifying guide lines, extracting coordinate data, and providing visual feedback. The image recognition module performs multiple functions including guide line detection, coordinate extraction, and spatial relationship analysis. This multi-functionality improves productivity by consolidating what would otherwise require separate devices and processes, while the integration actually reduces overall system complexity compared to having multiple independent systems.

AI summary
A control system for construction machinery includes 3D camera configured to recognize an object located around construction machinery and capture an image, a position information receiving device configured to obtain a reference coordinate corresponding to a position of the construction machinery, a data processing device configured to obtain a relative coordinate of the object relative to the construction machinery from the image and convert the relative coordinate based on the reference coordinate to obtain a three-dimensional coordinate, and a control device configured to display the image having the three-dimensional coordinate on a screen.
