    AAScan is an open source, Arduino-powered 3D scanner that uses your phone

    Arduino Team — February 18th, 2020

    3D scanners are amazing tools that literally let you turn everyday things into three-dimensional computer models. As seen on Reddit, if you want to make one yourself — using little more than a spare Android phone, Arduino, stepper motor, and 3D-printed parts — the AAScan by QLRO could be an excellent option.

    The device spins an object on a 3D-printed turntable using an Uno and ULN2003 driver board, allowing it to take ~180 images automatically via a Python script running on the phone. These images are then combined in Meshroom to create a brand new 3D model. 

    You can check out a demo of AAScan in the video below, rotating an apple to take pictures of each side.

    Pictures can be a great way to record an object or project, but typically only does so in one perspective. In order to capture things in three dimensions, you’ll need to be able to snap multiple photos and stitch them together with software.

    To take all the photos required for this process, “thomas_openscan” has come up with an automated device that rotates the object as needed, allowing him to capture images using a DSLR camera or even smartphone.

    An early prototype is shown here, which actually moves a phone around the scanned object. The later, more refined version manipulates the object itself using an Arduino Nano and a pair of drivers to control a pair of bipolar stepper motors. 

    More information is available here and over on Thingiverse, and can be purchased or built depending on your needs.

  • Creator Shows How To Make a 3D Scanner Using Rasperry Pi Cameras

    Creator Shows How To Make a 3D Scanner Using Rasperry Pi Cameras

    Reading Time: 2 minutes

    The arrangement takes four images at the same time to create a 3D model of the object.

    A creator on Hackaday has developed a novel scanner which can instantly capture a 3D surface. Going by the name ‘Jolar’, the developer has been busy refining his 3D scanner project from Oxford Hackspace.

    The scanner consists of four Raspberry Pi Zero cameras which can capture the desired object from different angles. The cameras are synchronized and images are uploaded to the cloud once ready.

    The fitted projector projects a random pattern onto an object. However, for the projector to zoom more closely, Jolar fitted a lens from a pair of reading glasses.

    In combination, the cameras and projector capture the four images which are then uploaded for processing to a laptop.

    The 3D scanner also includes a Multi-View Stereo (MVS) algorithm that then turns the four images into a 3D model.

    The MVS matches up features within each image in order for the distance to be triangulated. By projecting multiple features onto an object, a more accurate 3D mesh can be returned.

    Jolar uses VisualSFM, an application for 3D reconstruction that uses motion, to do the image processing. The resulting files are then opened in MeshLab or CAD.


    Scanning with Raspberries

    It’s not the first time Raspberry Pi cameras have been used in connection with 3D printing.

    Indeed, user ‘Richard’ has created a Raspberry Pi 3D Scanner which consists of 100 of the Pi cameras. It allows him to take full body shots of people or animals (even the ones who don’t like to sit still).

    A model from 100 photos can then be created using Autodesk Recap 360 or Agisoft Photoscan. In turn, these models are then used to develop the 3D print.

  • HP Z 3D Camera Offers HP Sprout’s 3D Scanning Capabilities For a Fraction of the Price

    HP Z 3D Camera Offers HP Sprout’s 3D Scanning Capabilities For a Fraction of the Price

    Reading Time: 3 minutes

    At CES, HP released a new “Z 3D Camera” which offers the 3D scanning capabilities of the Sprout Pro PC in a portable camera accessory. It attaches to your computer monitor and can help you scan 3D items in no time.

    At CES 2018, HP Inc. has announced its new Z 3D Camera. The company thinks this 3D camera will “help reinvent creative workflows and spark spontaneous real-time sharing of documents and physical work product.”

    So, what’s special about it? HP’s Z 3D camera allows creators to capture in 3D without having to buy a specialized scanner. Up until now, HP has offered the Sprout Pro which has a unique 3D camera integrated into the computer.

    HP’s Sprout PCs made 3D scanning easier with a down-facing camera and a touch mat. However, the system costs over $3,000. Instead, HP has now taken the 3D scanner feature and turned it into a portable option which can be attached to most monitors. With the Z 3D Camera and the mat, the same 3D camera technology will cost just $599.

    To 3D scan an item, you simply rotate the object in your hands or position it underneath the camera on your desk.

    “The demand for 3D content has skyrocketed and 3D pros are constantly looking for new hardware and software innovations to increase their end-to-end productivity, from concepting to production… HP Z 3D Camera helps speed up modeling, reinvent the creative palette and protect the artistic point of view as more people enter the profession and workflows become increasingly automated,”  said Louis Kim, global head of Immersive Computing, Personal Systems, HP Inc.

    Highlights of the HP Z 3D Camera

    The company claims to have had CG artists, 3D designers, game developers, and digital fine artists in mind while developing the camera. It will be able to capture and digitize 3D objects, 2D documents, and live video, alike the Sprout Pro.

    But there are compromises. You’ll be losing some of the features of the Sprout Pro: There’s no included projection capability of the Sprout Pro, also multitouch is not available with HP’s Z 3D camera.

    HP explains that the Z 3D camera will minimize desktop space thanks to a unique design. Although the technology is slightly scaled down in terms of its lack of Touch Mat and light projector, it still includes a 3D depth-sensing camera and a 14.6MP 2D camera.

    It also uses a technology called SLAM (Simultaneous Localization and Mapping) to track, scan, and construct a 3D model in real time. The resulting high-resolution “computer-graphics-friendly” images and textures can then be used for 3D and VR applications.

    Anyone with Windows 10 will be able to export models to PowerPoint 3D, Paint 3D and Mixed Reality Viewer. HP is also making it easier to share captures or live videos of notes and sketches from your desktop and hope to offer a “more human experience”.

    HP Z 3D Camera will be available in March but only in the US. Check out the company’s website to keep up to date and find out more.

  • Sony’s 3D Creator Scanning App Integrates with New MyMiniFactory App

    Sony’s 3D Creator Scanning App Integrates with New MyMiniFactory App

    Reading Time: 2 minutes

    You can now 3D scan your face using Sony’s 3D Creator, add a hat using MyMiniFactory’s new app and 3D print the whole thing with a few simple clicks.

    You may remember Sony’s launch of the 3D Creator app which allows Xperia owners with compatible devices to scan a face or object in 3D (find an in-depth review of the scanner app here).

    Since then, the company has been working on new capabilities for the scanning app. The latest development is the integration with a MyMiniFactory app.

    You’ll likely know MyMiniFactory as the 3D printable object-sharing platform which is free to use. However, the company has now released an app which allows 3D printer owners to explore 3D printable objects from their phone.

    But, as well as being able to search through 40,000 objects, it’s also possible to upload from Sony’s 3D Creator scanning feature directly via MyMiniFactory’s Android app.

    The companies hope these new integrations make sharing and remixing for desktop 3D printing easier.

    MyMiniFactory and Sony Xperia Come Together

    Owners with compatible devices will be able to use Sony’s 3D Creator to scan any object or face in 3D. It’s then possible to then share the 3D scan through the MyMiniFactory app.

    Then, after sharing a 3D scan with MyMiniFactory, it’s possible to remix the face with just one click. The company claim they were inspired by Snapchat filters. For example, you could add a hat to your 3D face.

    Sony add in a press release that they’re “adding a whole new layer of fun and social sharing to the 3D scanned head. It has never been so easy and magic to edit and remix a 3D scan.”

    If you’re taken by your new hat, MyMiniFactory also offers the solution of Click & Print. This enables you to launch your 3D prints from your phone to your printer. Supposedly, this reduces the need for the “steep learning curves of desktop-based software.”

    Sony claims to be reducing the time taken for manual work down to just a short number of clicks.

    If you’re a Sony 3D Creator user already, you can find the MyMiniFactory Android app linked from the Sony app. If not, search for the MyMiniFactory app in the Google Play Store. However, if you don’t own a compatible phone, read All3DP’s review instead.
