Where the scan technology lovers go to grow!
Accuracy, precision, resolution, …: a demystification of the terms around the error of measurement quantification
In the field of 3D body scanning the topic of measurement, and in particular error in measurement, is highly important. We know that in all measurements some degree of uncertainty is present, which can be expressed as error in measurement.
You’ve heard about the 3D scanner for scanning the human body, but you don’t know what it’s for. Or maybe you’re already using one and you want to know more about the different options you have, then this article is for you.
Anthropometry is the measurement of the size and proportions of the human body.
Although 3D scanning and photogrammetry aim to produce a 3D model of an object/human/environment, the technologies used behind are completely different.
Visualize a prosthetic arm along with the sensory capabilities of a human arm, or a robot ankle that simulates the healthy and balanced ankle’s action to altering activity.
Until the 20th century, prostheses were often heavy wooden gear with a gross shape and limited function, which made them unaesthetic and not functional. Today, however, we have prosthetics controlled with our minds, predicting movement, and fitting perfectly each person thanks to 3D printing technology.
Imagine the scene:you wake up in a hospital without remembering what happened and you find out that your left hand is no longer there. Read more on prothesis.
