Here at Physical Digital® we thought we would celebrate the start of Spring by capturing the beauty of the daffodil by 3D scanning one. We used our high-resolution and high-accuracy GOM optical measurement equipment to capture the delicate nature of the flower and the results are simply stunning!
The 3D scanning process
We started the process by creating a fixture on which to place the Daffodil for 3D scanning within our automated measurement cell, the GOM ATOS ScanBox. The fixture increases process stability for measurement and allows for repeatable scans in a fixed position within the scan volume, while also allowing the maximum optical access across the whole surface of the flower.
The volume used to complete the 3D scan was 170 measurement volume which is the highest resolution and suitable for the size of the Daffodil. Measurement volumes can be adjusted to suit the required detail and resolution needed for size of the object being captured, and the level of accuracy required for the project.
Using 3D Structured Light (3DSL), our non-contact optical scanner projects a phase-shifting fringe pattern onto the object in order to capture the full-surface data. Once complete, a polygon mesh is produced by the specialist inbuilt software. This high-resolution polygon mesh can be exported as an .STL file which can be used for further inspection and analysis. The data can also be used to 3D print the object or it can be passed onto our in-house design team for full reverse engineering for remanufacture, ideally suited to legacy products where the CAD model is not available for reproduction.
The data captured for this example perfectly showcases the intricate detail that our industry-leading non-contact optical measurement systems can capture.
As you can see from the images, the veins on the delicate petals on the Daffodil are clearly visible. The non-contact aspect of our GOM metrology systems allow us to capture precious surface information without jeopardising the integrity of the object. This has proved particularly useful for historical artefacts and is why we are the preferred supplier of 3D scanning and inspection for major Aerospace OEM’s, where the freefrom shapes are inherently difficult to capture but required where component integrity is critical.
