UAV Property Condition Assessment for Construction Progress Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring property development stages during construction is costly and burdensome due to the need for multiple in-person inspections, and aligning inspector schedules with construction stages is unpredictable.
Innovation Solution
A system utilizing unmanned aerial vehicles (UAVs) to gather image data over time, allowing for remote assessment of property development stages without physical inspections, and generating models of the property based on this data to validate construction progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple in-person inspections are conducted to monitor property development stages, then measurement precision and reliability of construction progress assessment are improved, but loss of time and operational complexity increase
Solution Approach 1:
The patent creates digital copies (aerial images and 3D models) of the construction site to replace physical inspections. UAVs capture aerial images at different construction stages, which are then processed into 3D models that accurately represent the property development progress, eliminating the need for inspectors to physically visit the site multiple times
Solution Approach 2:
The patent replaces the mechanical system of in-person inspections with an automated aerial imaging system. UAVs equipped with cameras automatically capture and transmit images of the construction site, and computer algorithms automatically analyze these images to assess construction progress, replacing the manual inspection process entirely
2Reliability
If in-person inspections are used to assess property development condition, then reliability of construction stage validation is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent makes the UAV system multi-functional by equipping it with various sensors (cameras, LIDAR, thermal imaging) that can capture different types of data. The same UAV platform performs multiple functions including aerial photography, 3D modeling, and construction progress monitoring, replacing multiple specialized inspection tools and procedures
Solution Approach 2:
The system enables self-service by allowing automated analysis of aerial images to assess construction progress. The computer algorithm automatically compares captured images against planned construction stages, validates progress without human intervention, and generates reports, making the inspection process self-sufficient
3Adaptability or versatility
If manual inspection scheduling is used to align with construction stages, then adaptability to construction timeline is improved, but productivity and efficiency decrease
Solution Approach 1:
The patent implements periodic automated monitoring where UAVs are scheduled to automatically capture aerial images at predetermined intervals or at key construction milestones. This periodic action ensures consistent monitoring of construction progress without requiring manual coordination, maintaining adaptability while improving efficiency
Solution Approach 2:
The system incorporates feedback mechanisms where the automated analysis of aerial images provides real-time information about construction progress. This feedback loop allows the system to automatically adjust monitoring frequency and alert stakeholders when construction stages are completed or delayed, improving both adaptability and productivity
Data Source
AI summary
A technique for assessing development condition of a property is provided that determines development condition for an individual property or properties of interest using image or other sensor data from one or more unmanned aerial vehicles taken over the development process. A property condition output may be generated to indicate a condition of the property or properties.
