It should be noted that both methods also required editing of the 3D model to remove “dirt” and adjust some shapes. It’s also possible to use photogrammetry without a kit, for example for larger objects, by simply taking photos of the object by yourself, but results can be mixed as found out by “ Making for Motorsport” when comparing CR-Scan Lizard 3D scanner with photogrammetry using only a DSLR camera. Note that a complete kit with pre-soldered boards, a Raspberry Pi 3B+, and an Arducam 16MP camera module goes for around 298 Euros including VAT. The easiest way to get started would be to purchase one of the kits directly from the project’s shop for 107 Euros and up. You’ll find the latest Python software for Raspberry Pi and a custom Raspberry Pi OS image on Github, and 3D files for the scanner and Raspberry Pi shield on Thingiverse. Here’s a short demo of how this all works. It’s free thanks to a donation, but usage is limited, and whether it can stay up and running may depend on the continuous support from donations. There’s also the OpenScanCloud that will process the photo in the cloud with minimum user intervention. Meshroom is the most popular and actively developed. Open-source Photogrammetry programs include VisualSFM that’s fast but only outputs point clouds, as well as Meshroom and Colmap with mesh and texture support, but you’ll need a machine equipped with a CUDA-capable GPU for both. The photos can be imported to Photogrammetry software for processing. Depending on the complexity of the object, you may have to take hundreds of photos. The system would then take photos from different angles under the same light conditions thanks to the ring light. An alternative design is the OpenScan Mini pictured above with the Raspberry Pi camera and ring light attached to it, and suitable for scans up to 8x8x8 cm. There used to be an Arduino kit, but it has now been deprecated. 8x M3x8mm, 10x M3x12mm, 8x M3 nuts, 50圆mm steel rod, 2x 1m stepper motor cableĪlternatively, you could use a smartphone or a compatible DSLR camera with a ring light mounted on a tripod.1x Pi Camera Ringlight (optional but highly recommended), pre-soldered or solder-yourself.1x Pi Shield (either pre-soldered or solder-yourself). 8MP Raspberry Pi Camera 8MP with 15cm ribbon cable (or compatible like Arducam 16MP).If you’re going to use the Raspberry Pi as shown on the right side of the image, you’ll also need 1x Optional Bluetooth remote shutter control for smartphones.The OpenScan Classic kit above allows for 18x18x18cm scans and comes with the following components: WiFi channel scanner and WiFi networks through channels in 2. The OpenScan kits include 3D printed parts such as gears, two stepper motors, a Raspberry Pi shield, and a Ringlight module to take photos of a particular object from different angles in an efficient manner. Note: We also sell and loan pre-configured Raspberry Pi feed systems - inquire if you are. The open-source project was brought to my attention after I wrote about the Creality CR-Scan Lizard 3D scanner. OpenScan is an open-source DIY 3D scanner that relies on Photogrammetry and works with Raspberry Pi camera modules, compatible ArduCam modules, as well as DSLR cameras, or the camera from your smartphone.
