Metrological 3D scanning is a process that involves using three-dimensional scanning technology to capture the geometry of a physical object in order to obtain accurate and detailed measurements. Below is a detailed description of the process:
- Preparing the object: Before you begin scanning, it is important to prepare the object to be scanned. This may include cleaning the surface, removing any obstructions, and placing reference markers if necessary.
- 3D Scanning: A 3D scanner is used to capture the geometry of the object from different angles and perspectives. The scanner emits structured light or lasers onto the surface of the object and collects the information to create a digital 3D model.
- Data processing: Once the scan is complete, the captured data is processed using specialized software. At this stage, possible errors are eliminated, the different views are merged, and an accurate 3D model of the object is generated.
- Analysis and metrology: With the generated 3D model, precise measurements of the object's dimensions, shapes and tolerances can be made. The measurements obtained can be compared with the original design specifications to verify quality and accuracy.
- Results report: Finally, a detailed report is generated that includes the measurements taken, the deviations found, the tolerances met and any other relevant information. This report is usually used to make decisions in manufacturing processes, quality control, reverse engineering, among others.
In short, metrological 3D scanning is an advanced process that enables accurate and detailed measurements of physical objects using three-dimensional scanning technology, which is useful in a wide range of industrial and design applications.
