3D Building Wall Area Estimation Using Aerial Line Drawings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for estimating building wall area are costly and inaccurate, often requiring manual measurements or outdated blueprints, and lack efficient methods for verification.
Innovation Solution
A system that generates an estimated wall area measurement report using multiple line drawings of a building, determining angles of vertical walls, grouping similar angles, and selecting the most representative view to calculate wall area, incorporating graphical user interfaces and three-dimensional modeling for accurate measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used to estimate building wall area, then measurement precision may be maintained, but productivity decreases and costs increase
Solution Approach 1:
The patent uses aerial images as copies of the building to create a digital model for wall area estimation, replacing the need for physical manual measurements while maintaining accuracy through image-based analysis
Solution Approach 2:
The patent replaces mechanical manual measurement tools and processes with an automated computer-based system that processes aerial images and calculates wall area through software algorithms
2Measurement precision
If original building plans are used for wall area estimation, then measurement precision may be improved, but adaptability decreases when plans are unavailable or outdated
Solution Approach 1:
The system makes the building itself (through aerial imaging) serve as the source of measurement data, eliminating dependency on external documents like blueprints that may be unavailable or outdated
Solution Approach 2:
The patent performs preliminary aerial imaging and digital model creation that can be stored and reused for future estimation needs, making the system adaptable to different time points without requiring updated physical measurements or plans
3Measurement precision
If multiple perspective views are generated for wall area estimation, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent creates a universal digital model from aerial images that can generate multiple perspective views and perform various measurements through software, rather than requiring separate physical measurement systems for each view
Solution Approach 2:
The patent transitions from two-dimensional aerial images to a three-dimensional digital model, enabling multiple perspective views and comprehensive wall area analysis from a single integrated system
