Composite X-ray and Laser Scanning for 3D Object Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray machines struggle to accurately define the surface contours of complex objects during scanning, while providing detailed internal part reconstructions, leading to incomplete 3D object representation.
Innovation Solution
A machine combining an X-ray scanning system with a surface scanning tool, such as a laser or structured light scanner, positioned on the same wall as the X-ray source, allowing for simultaneous X-ray and surface scanning, and processing the combined data for enhanced 3D reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If X-ray scanning is used to inspect internal parts, then internal structure detail is improved, but surface contour definition deteriorates
Solution Approach 1:
The patent combines X-ray scanning and laser surface scanning into a single integrated inspection system. The X-ray source and laser scanner are positioned on the same wall of the inspection booth, allowing both scanning modes to operate simultaneously or sequentially on the same object. This merging of different scanning technologies resolves the contradiction by providing both internal structure detail (from X-ray) and surface contour definition (from laser) within a single system.
Solution Approach 2:
The inspection machine is designed with multi-functionality, capable of performing both X-ray internal scanning and laser surface scanning. The system can switch between or combine these different inspection modes to address various inspection needs. This universal design allows the same machine to provide comprehensive inspection data including both internal structures and external surfaces, resolving the limitation of single-function X-ray machines.
2Reliability
If only X-ray scanning is used, then internal parts are detected, but comprehensive 3D reconstruction deteriorates
Solution Approach 1:
The system merges X-ray scanning data with laser surface scanning data to create a comprehensive 3D reconstruction. The X-ray provides internal structural information while the laser scanner captures external surface geometry. By combining these two data sources, the system recovers complete object information including both internal and external features, eliminating the information loss that occurs when using only X-ray scanning.
3Manufacturing precision
If surface scanning tool is added to the machine, then surface contour definition is improved, but device complexity increases
Solution Approach 1:
The surface scanning tool is integrated with the existing X-ray inspection machine by positioning both components on the same wall of the inspection booth. This spatial merging allows the system to share common infrastructure such as the inspection chamber, control systems, and data processing capabilities, thereby reducing the overall complexity that would result from completely separate systems.
Solution Approach 2:
The machine is designed as a universal inspection platform that can perform multiple scanning functions. By incorporating both X-ray and laser scanning capabilities into a single multi-functional device, the system achieves comprehensive inspection abilities while managing complexity through integrated design and shared resources.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This combination enables more accurate and comprehensive 3D reconstruction of objects by improving the definition of surface contours and internal parts, resulting in a more effective inspection and representation compared to X-ray scanning alone.
Implementation Method 1
X-ray machines are known to be used to check whether there may be defects in the structure inside the products
Implementation Method 2
radiation source associated with movement means of the same capable of positioning the beam at a predetermined height and orienting it in the direction of the object
Implementation Method 3
This type of equipment emits rays that fly in a straight line until they encounter something to hit. When they find it, they bounce and move back to the source itself
Implementation Method 4
Surface scanning tools (e.g. laser or structured light scanners) are tools capable of measuring the position of hundreds of thousands of points at very high speed
