Construction Equipment Environment Data Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction equipment automation systems face challenges in accurately generating environment data around the equipment, as existing sensors often include the equipment itself in the data, leading to noise and inefficiencies in processing and trajectory planning.
Innovation Solution
An apparatus comprising a member position data generating module, an environment data generating module, and a data processing module that converts sensor data into relative coordinates to exclude the construction equipment's own data, generating accurate environment data by defining three-dimensional areas centered on equipment members and removing unnecessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are used to generate environment data around construction equipment, then environment data can be acquired, but the data includes the equipment itself causing noise and processing inefficiency
Solution Approach 1:
The patent extracts and removes data representing the construction equipment itself from the environment data acquired by sensors. The data processing module identifies and excludes self-represented data points, keeping only the surrounding environment data, thereby eliminating noise and improving both measurement precision and processing efficiency
2Loss of information
If sensors capture environment data around construction equipment, then surrounding environment information is obtained, but data representing the equipment portion needs to be removed
Solution Approach 1:
The system extracts only the necessary environment information while removing equipment self-data. The data processing module filters out points representing the equipment while preserving surrounding environment data, maintaining information completeness without requiring complex manual processing
Solution Approach 2:
The construction equipment uses its own sensor data to automatically identify and remove its self-representation from the environment data. The system performs self-identification and self-filtering, reducing the need for external intervention and simplifying the overall processing complexity
3Reliability
If environment data includes the construction equipment, then complete sensor data is captured, but trajectory planning and automation are affected by noise
Solution Approach 1:
The data processing module extracts and removes equipment self-data from the complete sensor dataset, reducing data volume while improving trajectory planning reliability. Only relevant environment data is retained for automation and navigation decisions
Solution Approach 2:
The patent segments the sensor data into two categories: equipment self-data and surrounding environment data. By separating these segments, the system can process only the necessary environment portion, reducing data volume while maintaining high reliability for trajectory planning
