A 3D selfie is a 3D-printed scale replica of a person or their face. These three-dimensional selfies are also known as 3D portraits, 3D figurines, 3D-printed figurines, mini-me figurines and miniature statues. In 2014 a first 3D printed bust of a President, Barack Obama, was made. [1] 3D-digital-imaging specialists used handheld 3D scanners to create an accurate representation of the President.
The capture of a subject as a 3D model can be accomplished in many ways. One of the methods, is called photogrammetry. Many systems use one or more digital cameras to take 2D pictures of the subject, under normal lighting, under projected light patterns, or a combination of these. Inexpensive systems use a single camera which is moved around the subject in 360° at various heights, over minutes, while the subject stays immobile. [2] More elaborate systems have a vertical bar of cameras rotate around the subject, usually achieving a full scan in 10 seconds. [3] Most expensive systems have an enclosed 3D photo booth with 50 to 100 cameras statically embedded in walls and the ceiling, firing all at once, eliminating differences in image capture caused by movements of the subject. [4] [5] [6] A piece of software then reconstructs a 3D model of the subject from these pictures. [4] [2] One of the 3D photo booth, which creates life-like portraits, is called Veronica Chorographic Scanner. [7] The scanner participated in the project of Royal Academy of Arts, where people could have themselves scanned. The scanner utilized 8 cameras taking 96 photographs of a person from each angle. Photogrammetry scanning is generally considered more life-like, than scanning with 3D scanners. [8] Mobile based Photogrammetry apps such as Qlone can also be used for 3D capturing a person. [9]
Another method for capturing a 3D selfie uses dedicated 3D scanning equipment which may more accurately capture geometry and texture, but take longer to perform. Scanners may be handheld, tripod mounted or fitted to another system that will allow the full geometry of a person to be captured. One of the well-known full body 3D scanners are Shapify booth, based on Artec Eva 3D scanners, Cobra body scanner by PICS-3D and Twindom Twinstant Mobile. [10]
Production of 3D selfies [11] is enabled by 3D printing technologies. This includes the ability to 3D print in full color using gypsum-based binder jetting techniques, giving the figurine a sandstone-like texture and look. [5] Other 3D printing process may be used depending on the desired result. These products can also be produced in a full colour resin format using Mimaki technology, both of which processes can be found in Selftraits 3D Selfie products.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes, decode the data contained in the barcode to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyse the barcode's image data provided by the sensor and send the barcode's content to the scanner's output port.
An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
A photo booth is a vending machine or modern kiosk that contains an automated, usually coin-operated, camera and film processor. Today, the vast majority of photo booths are digital.
A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This lets cameras that were designed to use film take digital photographs. These camera backs are generally expensive by consumer standards and are primarily built to be attached on medium- and large-format cameras used by professional photographers.
3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance. The collected data can then be used to construct digital 3D models.
The following outline is provided as an overview of and topical guide to photography:
Scanography, more commonly referred to as scanner photography, is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed "photo" scanner with a CCD array capturing device. Fine art scanography differs from traditional document scanning by using atypical objects, often three-dimensional, as well as from photography, due to the nature of the scanner's operation.
A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Unlike metal detectors, full-body scanners can detect non-metal objects, which became an increasing concern after various airliner bombing attempts in the 2000s and some scanners can also detect swallowed items or hidden in body cavities of a person. Starting in 2007, full-body scanners started supplementing metal detectors at airports and train stations in many countries.
PhotoModeler is a software application that performs image-based modeling and close range photogrammetry – producing 3D models and measurements from photography. The software is used for close-range, aerial and uav photogrammetry.
A selfie is a self-portrait photograph, typically taken with a digital camera or smartphone, which may be held in the hand or supported by a selfie stick. Selfies are often shared on social media, via social networking services such as Facebook, Twitter, Snapchat, and Instagram.
Optical braille recognition is technology to capture and process images of braille characters into natural language characters. It is used to convert braille documents for people who cannot read them into text, and for preservation and reproduction of the documents.
A light stage is an active illumination system used for shape, texture, reflectance and motion capture often with structured light and a multi-camera setup.
A space selfie is a selfie that is taken in outer space. This include selfies taken by astronauts, machines and by indirect methods.
Between 2011 and 2018, a series of disputes took place about the copyright status of selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. The disputes involved Wikimedia Commons and the blog Techdirt, which have hosted the images following their publication in newspapers in July 2011 over Slater's objections that he holds the copyright, and PETA, who have argued that the macaque should be assigned the copyright.
Google Camera is a camera phone application developed by Google for the Android operating system. Development for the application began in 2011 at the Google X research incubator led by Marc Levoy, which was developing image fusion technology for Google Glass. It was publicly released for Android 4.4+ on the Google Play Store on April 16, 2014. It was initially supported on all devices running Android 4.4 KitKat and higher, but became only officially supported on Google Pixel devices in the following years.
A selfie stick is used to take photographs or video by positioning a digital camera device, typically a smartphone, beyond the normal range of the arm. This allows for shots to be taken at angles and distances that would not have been possible with the human arm by itself. The sticks are typically extensible, with a handle on one end and an adjustable clamp on the other end to hold the device in place. As their name suggests, they are most commonly used for taking selfies with camera phones.
