Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection methods in construction sites lack efficiency in measuring installation precision and managing inspection data, as they do not effectively utilize images for inspection purposes and do not enhance the inspection process beyond conventional methods.
Innovation Solution
An inspection processing system that includes a control unit connected to a photographing unit and an output unit, which identifies the current position, displays a virtual three-dimensional model of a structure, superimposes it on a structure image, and records evaluation results in an inspection information memory, enabling efficient inspection and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional inspection methods are used, then inspection can be performed, but inspection efficiency remains low and data management is inefficient
Solution Approach 1:
The patent replaces manual inspection processes with an automated image processing system. The control unit automatically captures images, identifies current positions, generates virtual images, and records evaluation results without manual intervention, thereby substituting mechanical human operations with automated electronic systems to improve inspection efficiency and reduce time loss.
Solution Approach 2:
The inspection system performs self-service by automatically conducting the entire inspection workflow. The control unit independently captures images, processes them to generate virtual images, evaluates inspection items, and records results without requiring external manual operations for each step, enabling the system to serve itself and significantly improving productivity.
2Measurement precision
If markers are arranged on structures for inspection, then installation precision can be measured, but the process is not optimized for efficiency and requires additional preparation time
Solution Approach 1:
The patent extracts the inspection functionality from complex physical marker arrangements and concentrates it into an automated image processing system. By taking out the essential measurement function and implementing it through automatic image capture and virtual image generation, the system maintains measurement precision while reducing process complexity and eliminating the need for physical marker preparation.
Solution Approach 2:
The system creates a virtual copy (virtual image) of the structure based on captured images and current position data. This virtual image serves as a digital replica that can be analyzed without physical markers, maintaining measurement precision while simplifying the inspection process and eliminating the need for complex physical marking systems.
3Loss of information
If photographed images are stored without integration, then images can be recorded, but understanding design versus actual installation differences becomes difficult
Solution Approach 1:
The patent merges multiple data elements (captured images, current position information, virtual images, and evaluation results) into an integrated inspection record. The control unit combines these elements and stores them together in association with each other, enabling easy comparison between design and actual installation by presenting all relevant information in a unified format rather than separate disconnected files.
Data Source
AI summary
An inspection processing system includes a control unit connected to a photographing unit and an output unit. The control unit includes circuitry. The inspection processing system identifies a current position, displays a virtual image of a three-dimensional model of a structure corresponding to the current position. The virtual image is superimposed on a structure image obtained from the photographing unit. The inspection processing system further obtains an evaluation result of an evaluation item of an inspection subject using the structure image on which the displayed virtual image is superimposed, and records the evaluation result in an inspection information memory in association with the position of the inspection subject in the three-dimensional model.
