Construction Site 3D Display With Selective Region Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dynamic nature of construction sites, including changes in topography and work machine operations, necessitates a technique for accurately and efficiently confirming the current situation.
Innovation Solution
A display system comprising a detection data acquisition unit, a three-dimensional data storage unit, a changed-portion specifying unit, and an update unit that updates and displays the three-dimensional data of a construction site to reflect changes over time, using a flight vehicle equipped with sensors and a server to manage and display real-time updates.

Engineering Contradiction Analysis
1Reliability
If the entire three-dimensional data of the construction site is updated repeatedly, then the situation confirmation is kept up-to-date, but the data processing load increases and detection density decreases
Solution Approach 1:
The patent divides the three-dimensional data into multiple detection regions (first detection region and second detection region) based on spatial segmentation. Instead of updating the entire dataset, the system updates only the changed portion within specific regions, reducing processing load while maintaining accuracy where changes occur.
Solution Approach 2:
The patent extracts only the changed portion of the three-dimensional data from the complete dataset. By identifying and separating the modified region from the unchanged regions, the system processes only the necessary data for updates, improving efficiency while preserving overall data integrity and detection density.
2Reliability
If detection data is updated frequently to reflect changes, then the situation confirmation remains accurate, but the detection density of the system decreases
Solution Approach 1:
The patent applies different update strategies to different regions based on their characteristics. The first detection region (with changed portions) receives targeted updates while the second detection region maintains its original data structure. This localized approach preserves detection density in unchanged regions while ensuring accuracy in changed regions.

AI summary
A display system includes: a detection data acquisition unit that acquires detection data indicating a three-dimensional shape of a construction site in which a work machine operates; a three-dimensional data storage unit that stores first detection data indicating the detection data acquired at a first time point; a changed-portion specifying unit that specifies a changed portion between the first detection data and second detection data indicating the detection data acquired at a second time point after the first time point; an update unit that updates a part of the first detection data on the basis of the changed portion; and a display control unit that causes a display apparatus to display the updated first detection data.
