A brief introduction
One of the best reasons to get a smartphone is that you can use it as a 3D scanner. Some smartphones, such as the Sony Xperia XZ1, have a 3D scanning feature. Others, you must pick and download for yourself. Since 3D scanning is the newest hot feature in smartphones, you can learn how to use 3D scanning apps right away! While 3D scanning an object or an individual with a phone is relatively simple, it is always helpful to have some pointers. As a result, we’ve put together some helpful tips on how to get the most out of your next smartphone 3D scan!
What exactly is a Scan To 3D?
The visual image of the object or person you’re scanning is referred to as a 3D scan. Using a 3D scanning programme on your tablet or cell phone, or even a proper 3D scanning system, you capture the shape of an item (object, face, or body of a person) during the 3D scanning process. The sensors on each system gather data about the shape, depth, and colour of the object you’re 3D scanning, which is then used to create the final 3D file. After the 3D scan has been converted to a 3D format, you can use a 3D modelling programme to edit the result. This allows you to edit and use your 3D scan as an avatar in virtual reality games, as well as 3D print it. This is how the entity transforms from a physical to a digital state.
We’ve already shown you some 3D scanners on the market and some 3D scanning products that you can buy, but these are mostly aimed at professionals or are intended for educational purposes. The most popular and convenient way to 3D scan anything nowadays is with a smartphone or tablet. We showed you how to make a 3D scan with a tablet in a previous blog post. Today, we’ll show you how to make a 3D scan with your smartphone!
How to Search a 3D Object with a Smartphone?
If you already own a smartphone, you can use one of the numerous 3D scanning applications available on the market. The same guidelines apply to all 3D scanning applications for a good 3D scan, and we provide them for you! Generally speaking, the 3D scanning process is as follows. To begin, place the object or person you want to scan somewhere you can walk around it/her/him. Then, as directed by the app, you begin the scanning process, and the sensors in your phone’s camera collect all of the necessary data. The software converts your digital 3D model into your digital 3D model until the 3D scanning is completed and the data is obtained. The result can then be saved, 3D printed or used as an avatar in Virtual Reality games or other applications.
Using a smartphone to perform a Scan To 3D: Tips for Scan To 3D
Even if the 3D scanning apps are already very user-friendly and provide you with instant instructions on how to proceed to the next level, it is still essential to follow some simple and useful guidelines for a good 3D scan with a mobile phone. When making a 3D scan of an object or a 3D scan of a human, we have some clear guidelines on what to do and what not to do.
Tips for using a smartphone to Scan To 3D objects
When scanning an item, whether indoors or outdoors, make sure you use the proper lighting. When 3D scanning at night, it is recommended that you use bright light that is evenly distributed around your piece. If you’re scanning an object with complex geometry, or one that’s hollowed out or has edges, be careful not to produce shadows because the 3D scanning software won’t be able to read them properly. Also, when scanning around the object, try to maintain an even distance to ensure a consistent result. Furthermore, ensure that your models match the screen by adjusting your location and scanning from neither too far nor too near.
We suggest that you avoid 3D scanning moving or thin objects, such as tree leaves. Also, stay away from simple objects because they lack a geometric complexion and trigger reflexes that are difficult to catch during the 3D scanning process. Furthermore, when 3D scanning an object, be sure to distinguish it from its surroundings so that the 3D scanning depth sensors can capture the item’s volume. As a result, since transparent objects can’t be distinguished from their surroundings, they can’t be accurately depicted on a 3D scan.
Suggestions for scanning people in 3D with a smartphone
The process of scanning people’s faces in 3D is very easy. Scanning the face from ear to ear when walking around the individual will give you a standardised 3D scanning result. Be sure to catch different sides of the face so that no edges of the face are missed. It’s important, however, that you maintain a constant distance from the individual as you walk around him. Since stringy items are difficult to capture, don’t be surprised if the hair of the individual you’re 3D scanning isn’t perfectly depicted. To get the best results, position the individual you’re scanning against a single-colour, bright-enough background so that the camera’s depth sensors can distinguish the head from its surroundings. Last but not least, the person being 3D scanned should remain motionless and maintain the same facial expression throughout the process.
Smartphone Scan To 3D apps
If your smartphone doesn’t already have a 3D scanning app-enabled, you can get one. The photogrammetric approach is used in the 3D scanning apps mentioned below. Photogrammetry is a 3D scanning technique that converts 2D images into 3D models. It works by taking overlapping pictures of the 3D-scanned target from various angles. The programme then creates your 3D model by merging all of the files. As smartphones become more equipped with high-definition cameras, more 3D scanning software based on this technology emerges.
Trnio is the best 3D scanning app
Trnio is one of the best 3D scanning apps for cell phones on the market.
This 3D scanning software is only available for iPhones and comes with two scanning modes: object mode and scene mode. The software provides immediate assistance in both modes. The user walks around an object in the object model, and the app captures as the user travels in a circular pattern around the object. Scene mode is for free-formed scanning, which means you can use it to scan outdoor scenes or large objects in 3D. The beauty of this app is that it can also act as a social network. With this 3D scanning app, you can build a profile, a list of your 3D scans, and people can follow your account just like you can follow theirs.
Scann3d is a second Scan To 3D programme
If you’re looking for 3D scanning apps for Android phones, scann3d could be a good fit. The interface design is the secret to this software’s success. It’s simple to use even if you’re a novice because the 3D model provides instant reconstruction. It works by taking 20 to 30 overlapping images around the object you’re 3D scanning, and then automatically rendering it on the device. The 3D scan results are ready in a few minutes, depending on the number of input images. You can then use your Sketchfab account to build a 3D model that you can share without any post-processing!
itSeez3D is the third 3D scanning programme
The itSeez3D 3D scanner software connects an iPhone to an Occipital Structure Sensor, allowing users to capture in 3D. By processing images on its cloud server, this 3D scanner software produces high-quality 3D scans. It has the ability to capture people in 3D, a process that takes 5 to 10 minutes. However, the resolution is slightly lower than that obtained when scanning smaller specimens. Since the app is free to use, it allows for unrestricted 3D scanning. However, exporting the produced 3D scans – which are available in popular formats like.OBJ,.PLY, and.WRL. – costs $7 per file.
Qlone is the fourth 3D scanning programme
Qlone is a 3D scanning mobile app that scans in near real-time and produces results locally rather than via a cloud network. In order to use Qlone, users must first print a black and white mat (similar to a QR code). The item to be 3D scanned must then be placed on top of the printed map. Depending on the size of the object, users can print several maps. The ability to merge is a key feature of Qlone. For a better overall outcome, the 3D scanning app may combine two separate poses of the same 3D scanned object. Users can also post their 3D captures on social media sites like Facebook, WhatsApp, and other applications. Qlone is a free app, but exporting the created 3D scans – which come in popular formats like.OBJ,.STL,.PLY, and.X3D – costs $0.99 per file.
Bevel is the fifth 3D scanning programme.
Bevel is a mobile 3D scanner app that works on both iOS and Android devices. To use Bevel, you’ll need a small extension. It is, however, very straightforward. Simply plug it into the headphone jack on your smartphone and attach it. This 3D scanner software captures the scale and geometric detail with an eye-safe laser, while the smartphone’s camera captures the colour, texture, and other data. Unfortunately, this mobile 3D scanner is unable to produce 360° 3D scans at this time. It is, however, a very quick app, as it only takes a few seconds to capture an object in three dimensions. The 3D scanning software is free to download and use, even though the device costs $89 to purchase.
