This paper presents a new and high accuracy passive photogrammetry device intended for the three-dimensional scanning of the full human body. This device, named Bodygrammer, does not need laser beams, structured light, strips or any projection on the human body. It just takes a series of pictures of the body inside a cabin, whilst wearing an elastic mesh. Thus, it comprises only cheap and simple commercial elements to build, in just a few seconds, the digital 3D model of the body, also known as an avatar.
Since it is based on synchronized pictures, its acquisition time is only hundredths of second, avoiding unwanted movements by the person. This dramatically reduces the acquisition time while providing high accuracy in the results. For end users, the Bodygrammer is completely harmless. By using an elastic mesh there is no need to get naked in order to allow the system to take the images, which are deleted automatically right after the generation of the avatar. As the mesh mildly constrains the body, the resulting avatar is highly suitable for apparel applications.
This device performs very intensive calculations by means of a newly developed software based on GPU (Graphic Processing Unit) computation, that quickly obtains the avatar from just the pictures. The system allows us to get both manual and automatic 3D measurements such as chest circumference, limb length, waist perimeter, etc.
The Bodygrammer has already been thoroughly tested with real people for anthropometric studies. The resulting measurements have been successfully validated using third-party 3D contact techniques. In addition, all the individuals measured with the device have reported a satisfactory user experience which is of vital importance in order to be widely accepted in the real world.
