Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual construction inspection methods are inefficient and lack accuracy, making it difficult to ensure uniformity of construction quality standards, especially in complex and large-scale projects, and the introduction of virtual building models has not significantly improved efficiency due to complex processing and high calculation demands.
Innovation Solution
A computer-implemented construction inspection method that compares a first construction model established on-site with a second model based on design data, allowing for accurate and efficient inspections by aligning the actual construction with the design plan, using detection data from laser radar, image signals, or ground penetrating radar to create the first model, and sharing results through augmented reality devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection method is used, then inspection can be performed, but inspection efficiency is low and accuracy is poor
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated system using detection devices (laser radar, ground penetrating radar, image signals) to automatically capture construction data and compare it with design models, eliminating manual measurement errors and improving both efficiency and accuracy
Solution Approach 2:
The patent creates a digital copy (first construction model) of the actual construction based on detection data and compares it with the design model (second construction model), enabling automated accuracy verification without manual inspection
2Reliability
If virtual building construction three-dimensional model is introduced, then construction quality management is supported, but processing process becomes complicated and calculation amount increases
Solution Approach 1:
The patent segments the construction model into multiple regions based on detection data, allowing focused inspection of specific areas rather than processing the entire model, which simplifies the processing process and reduces calculation requirements while maintaining quality management reliability
Solution Approach 2:
The patent extracts only the necessary comparison elements between the first construction model and second construction model, focusing on detecting differences rather than processing complete models, thereby reducing computational complexity while ensuring quality management

AI summary
The present invention provides a construction inspection method, apparatus, and system. At a construction site, a first construction model is established based on detection data at the site, the first construction model is compared with a previously established second construction model based on design data, and an inspection result is confirmed in accordance with a comparison result so that the model established based on the result actually detected at the site is compared with the design model, and therefore it is possible to accurately reflect the difference between the actually completed situation of the construction and the desired design plan, the inspection result may be highly accurate, and the inspection may also be performed according to a unified standard. In addition, as the two models are directly compared with each other, the processing process is simple, and the inspection efficiency is high. It should be noted that the user at a location other than the site may also acquire the inspection result in a timely manner, which improves the inspection efficiency, enhances the convenience of inspection, saves time and effort, and improves the user experience.
