3D Optical Cameras (also known as 3D Scanners) can capture a human body, or only specific parts, to generate a very detailed 3D model within a few seconds. The result is a 3D model of the body which was captured in virtual format. Depending on the desired application and on the 3D Camera used, the 3D model can feature colors and textures to perfectly match the original person. It can also simply be a mesh, a sort of cloud of dots that form the body’s shape.

3D cameras are revolutionizing the way we capture, measure, and track evolutions of the human body, in various fields. Recent improvements in whole-body 3D scanning technologies are leading to a growing number of applications. Initially developed for the clothing industry, 3D body scanners are greatly improving our
ability to accurately measure and visualize a person’s body size, shape, and skin-surface area. Recent advances in whole-body scanning unlock new potential, especially for healthcare, garment fittings, ergonometric and now human intelligence forecasting applications.

Benefits of suing 3 D Optical Sensing Cameras
3D Cameras for body scanning is the perfect technology to capture in 3D a full human body or specific parts. When compared to traditional body imaging and measurement technologies, 3D body scanning offers many benefits.

Non-invasive

3D body scanning is an entirely non-invasive process. The 3D scanner never physically touches the subject. In the case of “handheld 3D scanners”, the device is held at a certain distance by the operator, who moves around the subject. In the case of a 3D scanning booth, the subject simply stands in the middle of the booth to be captured in 3D from all angles by a number of sensors, all without direct physical contact.

Fast
Scanning a person with a 3D scanning booth takes less than 10 seconds. When using a portable 3D scanner, the process can take several minutes and requires the subject to stand perfectly still.
Accurate
3D body scanners are high-precision tools and usually boast high resolution to produce highly detailed 3D models. They can detect things the human eye can’t, making such 3D scanners very valuable in many circumstances. The quality of the result depends of course on the type and features of camera being used. Some 3D scanning booths are capable of capturing several people at once with a stunning level of details, including colors and textures.

The sensing cameras observe the contrast along the stripes’ edge and assign those pixels X-Y-Z coordinates, quickly collecting precise, crisp scan data containing very little texturing. The software then transforms the data points into visible data that comprise an accurate, digital replica of the physical part.

In addition, there are today mobile applications that can create realistic 3D images based on people’s photos through smart phone cameras, computer imaging technology and machine learning algorithms.
