3D Modeling The World Around

  1. 3D Modelling The World Around You Using 3D Scanning and Photogrammetry To Create Models With Victor Gramm
  2. Who Am I? • My name is Victor Gramm • IT Professional of 18 years • Audio Engineer/Musician • Newly minted 3D Printer Enthusiast – (not an expert) • A family man
  3. Goals With 3D Printing • Connect with other 3D Printer Enthusiasts • Is a separate User-Group/Meetup outside the OKC-OSH warranted, given the current level of interest? • Learn everything I can about 3D Printing and related technologies, i.e. 3D Scanning, Photogrammetry, and 3D Modelling • Figure out ways in which I can apply what I learn to improve the lives of everyone around me • Find or create work in the 3D Industry in Oklahoma • Share what I learn along the way
  4. What will we be talking about today?• 3D Scanning • Photogrammetry • 3D Modelling • Some hardware and software solutions available • Hardware and software solutions with which I’ve had personal experience • 3D Printing/Tech User-Group/Meetup – Interest? • OKC Metro Area and Online Resources
  5. After The Discussion – Let’s Chat!• XBOX 360 Kinect Demonstration • Surely I’m not the only 3D Printer Enthusiast – Tell me about YOU! Let’s talk about your printers, scanners, and photogrammetry efforts! • I’ll stick around and scan anyone who’s interested for as long as I can using the Structure Sensor. I’ll need your email addresses to get the completed scans to you when they’re done rendering, however.
  6. What is 3D Scanning? Generally speaking, Wikipedia has it sort of spelled out: 3D Scanning is the process of analyzing real-world object or environment to collect data on its shape and possibly its appearance. -“3D Scanning.” Wikipedia, Wikimedia Foundation, 25 Apr. 2019, For our purposes, I like this definition: 3D scanning is the process of capturing digital information about the shape of an object with equipment that uses a laser or light to measure the distance between the scanner and the object. -Geometries, Absolute. “3D Scanning.” 3D Scanning, Laser Scanning, Laser Digitizing, 3D Imaging Definition, 2009, Scanning.html.
  7. Types of 3D Scanning Contact 3D Scanners – use a carriage, articulated arm, or a combination of the two with a probe that physically comes in contact with the object being scanned. An example of which being the Coordinate Measuring Machine (CMM), used in manufacturing with a high degree of precision. Hand-driven touch probes are also used to digitize clay models in computer animation. The problem with this type of scanning is that the act of scanning could change the physical form of the object being scanned.
  8. Types of 3D Scanning Non-contact active – use radiation or light and detect the amount of radiation passing through an object, or the reflection of light off the object for the measurements used to digitally reconstruct the object. The types of emissions used are light, radiation, and ultrasound, and typify the 3D Scanners we traditionally think of, when considering 3D Scanners. There are many systems for attaining 3D information via non-contact active methods: time-of- flight, triangulating, conoscopic holography, and hand-held laser methodologies; structured and modulated light methods; and CT and MRI scans in both medical and industrial applications.
  9. Types of 3D Scanning Non-contact passive – detect the ambient radiation like visible and infrared light, and is often one of the cheaper methods given that it can be achieved often with simple hardware. Stereoscopic, Photometric, and Silhouette techniques fall under this category of 3D Scanning.
  10. What is Photogrammetry? Photogrammetry is the art and science of making measurements from photographs, especially for recovering the exact positions of surface points. -“Photogrammetry.” Wikipedia, Wikimedia Foundation, 1 Apr. 2019, Photogrammetry has an extensive history dating back to the beginning of photogrammetry and a wide array of applications. Topographic mapping, architecture, engineering, manufacturing, quality control, police investigation, geology, and cultural heritage are all domains in which the technique is applied.
  11. Photogrammetry Cont. Photogrammetry involves many different methods from different disciplines and sciences. Each stage of processing borrows from fields of science that are, in of themselves, enormous in scope. 3-D Coordinates define the image in space, image co-ordinates define the image on film or on the sensor, exterior orientation defines the camera location in space, inner orientation define geometric parameters of the imaging process (perhaps some proprietary or well-known algorithms are employed), and additional observations (human interventions or AI) are all parts of the photogrammetric process. As complex as it may sound, photogrammetry, at this point, is one of the most accessible and accurate modalities for acquiring 3D data for 3D Modelling.
  12. What is 3D Modelling? 3D Modelling is when a 3-dimensional digital representation of a physical body is crafted by hand or using data (such as points or images collected from Scanning or Photogrammetry methods) to algorithmically assemble a model. 3D models are used in a variety of applications, but for our purposes today, the models created have been prepared for 3D Printing.
  13. The Basic Workflow Identify Subject -> Capture Subject’s Image Data via 3D Scanning or Photogrammetry -> Process Image Data/Render Mesh -> Cleanup Mesh and Prepare for Printing -> Slice and Print Depending on whether you are using a 3D Scanner or are practicing your Photogrammetry, as well as which software you’re working with, there may be additional steps involved in rendering a useable mesh for 3D Printing.

  27. Photogrammetry Samsung Galaxy 8 Note + Scann3D Purchased the subscription, might be some promise here. I didn’t complete a model here, however.
  28. Photogrammetry Samsung Galaxy 8 Note + Meshroom I don’t have adequate computing power for this and couldn’t complete the model. Looks to have the most data capture potential, however.
  29. Conclusions…for now • 3D Scanning available to average customers is a mixed bag of results at the sub-$1000 price point. Use diligence, caution, and critical thought when buying equipment – know your purpose and intent. • Depth-of-field sensors + Stereoscopic camera arrangements seem to be the bulk of commercially available 3D Scanners available, while higher-end (more expensive) scanners employ a broader set of technologies. • Open-source projects are alive and available, though it seems that MS and Apple do their best to quash the longevity of those projects, per usual. • Photogrammetry is accessible and produces the most detailed results, but is dependent on photography chops and computing power available – requires intensive processing for rendering models.
  30. Conclusions…for now 3D Scanning and Photogrammetry for the purposes of creating models to 3D print is more accessible now than it ever has been, and promises to continue along that trend as technologies shrink and become cheaper. It’s important to bear in mind, however, that 3D Scanning, Photogrammetry, and 3D Modelling are entire fields of study unto themselves, and it could be self-defeating to compare your results to professionals in these fields.
