How to scanning people

3d scanning of a person is a process by which information about a person (figure, body proportions, faces, hairstyle, facial expressions, eye color, all appearance features and individual traits) is transferred to a computer program. A 3d scanning humans model is created, which can then be printed on a 3D printer and get a three-dimensional figurine. This method quickly, efficiently and inexpensively performs 3D scanning of the face or the entire body of a person.

3d scanning people is used in various fields, for example, to create characters in computer games, animated videos, films, or in medicine for more accurate prosthetics, plastic surgery planning. And also, of course, a created 3D figurine is an original memorable gift, a souvenir that will give positive emotions to your family, friends or colleagues for a long time.

How the scanning process works

How to 3d scanning people? To scan the face, head or the entire body of a person, is used the so-called helical technology. A person stands on a special platform that rotates, and at this time our employee stands next to the scanner in his hands and carefully scans every part of the body.

3D scanning of people is carried out using professional high-precision equipment – a 3D scanner, it is best suited for this purpose. There are other scanners that cost less but are less accurate. The scanner works with an accuracy of 0.1 mm, and the data processing speed is up to 2 million points per second.

The scanner has only one minor drawback – to visualize a scanned person, you can view the resulting 3D image only on a laptop that is connected to the scanner via a USB cable. But the specialists are constantly working on improving the equipment used and following the latest in this area.

The 3D scanner is harmless to the eyes, so do not be afraid to do a 3D face scan, and in general, the 3D scanning process is absolutely safe for the human body.

At what temperature and under what lighting can 3D scanning be performed?

3D scanners are adapted to work not only in the metrological laboratory, but also directly on site – in the workshop, at the production site, at an open facility, etc. Handheld 3D scanners are highly portable and specifically designed for mobile use.

The requirements for cleanliness and air temperature are the same as for any office or workroom. Naturally, severe pollution, oil dust in the air, dusting is undesirable, since this is harmful to optics. Some scanners are equipped with a cooling fan and a dust filter to prevent contamination of the optics inside the device.

Laser rangefinder scanners are specially designed to work in difficult conditions and provide protection against dust, debris and water splashes (protection class IP 54).

Daylight or office lighting does not affect scan quality. The scanner illuminates the object with LEDs and lasers using specially designed high quality optics. Most likely, the equipment has polarizing filters and laser wavelength filters, thanks to which the scanner filters out noise and “sees” the scanned object the way it needs to. And you, using your normal lighting, see the detail the way you need it.

What does technical 3D scanning give?

1. You get the exact geometry of your part. There is no need to spend hours with a caliper, taking tens and hundreds of geometric dimensions and entering them into the sketch of the future part. often overlooked when measuring basic geometry.

2. You get the ability to measure complex geometry, angles, radii and their relative position, which in most cases cannot be obtained with simple measuring tools.

3. At all stages of design, you can compare the result of building a model with the results of 3D scanning. This greatly reduces the possibility of error.

4. The CAD software that exists today allows you to recognize primitives in the design of a part and their dimensions. When an engineer masters these tools, reversing engineering can reduce the design time by dozens of times compared to building from scratch, having measurements with simple measuring tools.

5. For many tasks, there is no need to rebuild the entire part. You can only make changes in the part of the model of interest.

6. You have the opportunity to build a “reciprocal” part of the part – for example, a mold, or vice versa – a model from a cast – with simple Boolean operations.

7. Quick creation and execution of design documentation and product rendering.

3D scanning rules

In order to achieve maximum similarity of a 3D figurine with the original and to successfully scan a human figure in the process of work, certain recommendations should be followed.

Specialists who carry out this task follow all these rules, so the result will meet all your expectations. Order a 3D scan of a person, and you will be able to get an accurate 3D model of yourself or your family and then print any number of 3D figures on a full body scanner. There are rules:

• you need to scan all parts of the body once, especially the face. If you scan a face several times, then the program will calculate the proportions and create a model as an average between all available 3D scans and it will turn out completely different from the face of the person being scanned, and it will take a very long time to manually sit and select frames;
• it is strictly forbidden for a person to move during the 3d scan human body, he must freeze in the chosen position for these few minutes and stand motionless on the shapify booth until the end of the procedure. Any tilt of the head, rotation of the torso, stepping over will lead to distortion and delamination of the image geometry;
• there is no need to use additional light if a full body scan of a person is being done to create a 3D figurine. The base texture for the 3d figurine can be obtained using LED flashes while the 3d scanner is running, this lighting will be enough;
• turntable speed should be low. A better and more accurate 3D scan of a person is obtained if the platform slowly turns, and sometimes even stops, so that it is more convenient to scan hard-to-reach places, such as palms or auricles.

Advantages of 3d scanning human body

Price/Terms

Body 3d scanner is usually a faster and better option than 3D modeling. Since 3D scanning takes only a few hours, while 3D modeling can take more than a few days.

Quality

3D scanning allows you to create high-precision 3d body measurements with an error of 0.1% or less, as well as completely repeat the geometry of the product.

To sum up

A 3D scanner is a device that allows you to get a 3D model (digital copy) of a physical object in a short time and with high detail, after which you can send the resulting model for 3D printing, refine the appearance, dimensions, model elements (reverse engineering). A 3D scanner is necessary for dental technicians and dentists, engineers, people of creative professions.
