Welcome back to the channel! Today, we have Eric Lao from Shining 3D to share his expertise on 3D scanning. If you’re interested in the scanners from Shining 3D that we offer at Vision Miner, you’re in the right place. We’re diving into your questions, so if you have more, feel free to leave them in the comments below, and we’ll cover them in the next video. Let’s get started!
Understanding Accuracy and Resolution
One of the common questions in the 3D scanning world revolves around accuracy and resolution. So, what’s the difference between the two? In simple terms, accuracy refers to how precisely a point is located in space, ensuring that the scanned point matches the real-world location. On the other hand, resolution is about the number of points and their spacing. A high-resolution scan has more points packed closer together. For example, an accuracy of 0.02 millimeters means a point is located with a precision of 0.02 millimeters, while a point spacing of 1 millimeter means that points are 1 millimeter apart.
Choosing the Right Scanner for Accuracy
When it comes to selecting a scanner for accuracy, consider the field of view. Scanners with a larger field of view, like the EinScan HX and H, offer better volumetric accuracy for larger objects. However, for more detailed surface features, scanners with a smaller field of view, like the Pro series, can provide higher resolution. The EinScan HX offers impressive accuracy, thanks to its laser scan mode that can reach a remarkable 0.05 millimeter point spacing.
Optimal Lighting Environments
Choosing the right lighting environment for your 3D scanning project is crucial. Ideally, scan in low-light conditions for better results, especially if you’re not concerned about texture or color. Scanners’ LEDs are designed to help the cameras detect the projection pattern accurately. Direct sunlight or other strong lighting can interfere with this pattern recognition. So, scanning on cloudy days or at night is preferable for the best results.
Utilizing Green Screens and Markers
If you’re aiming to scan large objects, utilizing markers and green screen techniques can be incredibly helpful. Using a black surface can effectively act as a green screen, making it easier for the scanner to focus on your object. The use of markers can also assist in the alignment of different parts of a larger object. You can even create a global marker file to streamline this process, ensuring accurate and efficient scans.
Post-Processing with Geomagic Essentials
Once you’ve collected your scan data, it’s time to consider post-processing. Geomagic Essentials is a powerful tool for handling large amounts of point cloud data and meshes. It’s especially valuable for professional engineers and serious 3D scanning enthusiasts. This software can clean up and extract features from the scan data, making it compatible with various CAD programs. Geomagic Essentials is essential for managing and preparing your scan data for further design and engineering work.
