London design studio " Sample & Hold was prompted to Scan you are all kinds of things: a Shoe, a carrot, The Heads of each member of the FC Barcelona team.

The Company has also worked with a company in Knightsbridge, London, that makes imprints of baby feet and heads.

"Sometimes you have a customer who wants a head-Scan of your child," says Sample & Hold Director Sam Jackson .

These scans were used for the bronze casts of the head of The Child , and the 3D scanning speeds up this process.

" Sample & Hold not need to do lasers, the 3D-Scan . Instead, it uses the good old 2D cameras. The trick is to use many of them - 67 in Total .

The subject or the object around in a rig with each camera in a kind of photographic area around you. With The Click of a button, an image is captured, from 67 different angles. These can then be merged together in computer software to a 3D model.

It is referred to as photogrammetry, and the simultaneous recording of visual and spatial information. As a technology-it's surprisingly old. People have experimented with various forms of it for More Than 150 years, but it is currently "just a moment," thanks in part to the low cost of digital cameras.

the Various 3D scanning technologies have different strengths. As Mr Jackson explained, photogrammetry is particularly good at capturing the visual quality of the objects.

"is It the color, the information, which is the important part," he says. Sometimes, if the technique doesn't work quite as well as intended - for example, people whose skin is extremely smooth and clear.

"We've been in situations with models in the very smooth skin, to remove blemishes, it is very difficult to capture, the type of skin. "

I explain, he would have no trouble finding a Scan of me in this context.

photogrammetry is increasingly used to insert true-to-life character models in the video and digitization of real-world landscape.

The Designer working on Call of Duty: Modern Warfare , the "dark" quality of the title, the in-game environments were praised. Photogrammetry helped to achieve that.

And a recent indie game, trueber brook, has scenes that were hand-made, like real models And Then the use of photogrammetry scanned in a variety of different light settings. These were then digitized.

Other industries, apply now to make photogrammetry, cheap, 3D-surveys of large sites or facilities. Often the fly, this includes a small camera-equipped drone to the structure in question, so that photos from many angles.

"Everyone has dropped a camera and cameras dramatically in price," explains Jan Böhm, an expert in photogrammetry at the University of London.

the raising of the standard drones, a British company that trains drone operators, offers courses in the field of aerial photogrammetry.

Instead of the staff to the Council building roofs to check them, some local authorities in the UK are now using drones to instead of scanning it in 3D, says James Dunthorne, a consultant for buoyancy.

"Instead of testing the asset physically, it can be done on a computer," he explains.

Some of the clients he has worked with, with the use of photogrammetry to the Next Level by applying exceptionally high-resolution cameras on drones. These are great pieces of equipment that would have been traditionally fixed to the bottom of the aircraft or helicopter.

railway transport companies, for example, the use of such cameras to ultra-detailed 3D models of The Track . Employees can then check that The Track is in place aligned with all the intersections and to get it right.

"the quality of The data, you are able to reach, that is stunning," said Mr Dunthorne. "I would call it, photogrammetry on steroids. "

Drone-based photogrammetry is cropping up everywhere. In the United States, Washington state transportation department's aviation division recently, the technology is being tested as a means for the detection of obstructive objects on The Runway at both airports, Prosser Airport and Sunnyside Municipal Airport.

A spokeswoman for The Department , confirmed to the BBC that The Work will continue.

"We have recently made Our Own drone bought to do with the intention of Our Own work for photogrammetry versus hiring a contractor," she says.

Often, though, a subcontractor, provide The Drones , or software photogrammetry surveys possible.

Pix4D, headquartered in Switzerland, makes software that converts the aerial photographs into 3D models. Each year, associated with the entire area, which increases by people with the help of the software, said the spokesperson for the Nikoleta Guetcheva.

"In the year 2018, our users mapped to More Than 450,000 square kilometres," she says. "This is ten times that of Switzerland. "

Ms Guetcheva, declares that this 3D mapping includes mines, arable land, communication towers, pipelines, and even under water assets.

Pix4D customers, such as periodic surveys, for example, construction sites, so that the progress can clearly be shown in 3D. Or, a mining company could use, photogrammetry, measurements of the huge piles of earth or raw materials, the excavated constantly.

"We have seen a great improvement of the cameras in the last few years... the stabilization of The Drones is better and better," says Mrs Guetcheva.

Depending on what you want to Scan , and where you might be on a fixed-wing aircraft or rotary wing drones. Fixed-wing devices have a greater range, but require sufficient space to safely launch and land.

Polish company FlyTech UAV makes a drone it's called, "Birdie", this can be changed to that of a fixed wing vertical take-off and landing version with some plants.

The Company has recently helped utility companies make great 3D models of electrical lines and poles. It is much cheaper than sending a helicopter to do the same surveys, FlyTech says.

It is a kind of mapping The World - One image at a Time .
