Solution Overview
Problem
Existing measurement systems for construction sites face high computational loads due to large volumes of three-dimensional point cloud data and are unable to immediately correct deviations found in data processed away from the construction site.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional point cloud data of the entire building are measured at a construction site, then comprehensive measurement coverage is achieved, but the volume of data becomes enormous and computational load becomes excessively high
Solution Approach 1:
The patent divides the building into multiple building components (columns, beams, slabs, etc.) and measures each component separately rather than measuring the entire building at once. This segmentation reduces the data volume and computational load while maintaining comprehensive measurement coverage, as each component is processed independently with its own manageable point cloud data set.
Solution Approach 2:
The patent extracts and processes only the essential geometric features (position, orientation, dimensions) of building components from the point cloud data, rather than processing all raw data points. This extraction approach reduces computational complexity by focusing only on the critical measurement parameters needed for construction verification.
2Measurement precision
If three-dimensional point cloud data are measured and processed in an office or workplace away from the construction site, then comprehensive analysis can be performed, but the deviation cannot be immediately corrected
Solution Approach 1:
The patent performs preliminary measurement and deviation analysis directly at the construction site using portable measurement devices, rather than waiting to process data later in an office. This preliminary action enables immediate identification of deviations and allows for real-time correction before construction proceeds, eliminating time delays while maintaining analysis accuracy through on-site computational capabilities.
3Reliability
If the entire building is measured to determine construction status, then complete construction monitoring is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The patent segments the construction monitoring process into component-level measurements of columns, beams, slabs, and other individual building elements. Each component is measured, processed, and verified independently, which maintains complete monitoring coverage while significantly improving measurement efficiency by avoiding the complexity of processing the entire building as a single unit.

AI summary
A measurement system includes: a storage configured to store design information including at least a dimension and a designed position of each of building components at a construction site; a component identifier configured to identify at least one of the building components constructed at the construction site as an identified building component, based on the designed position stored in the storage; a scanner configured to measure a distance and/or angle from the identified building component identified by the component identifier; a point cloud data generator configured to generate three-dimensional point cloud data, based on a result of the distance and/or angle measured by the scanner; and an actually measured position calculator configured to calculate an actually measured position of the identified building component, based on the three-dimensional point cloud data.
