3D scanning technology helps to understand our past

We know that 3D scanning technology  is changing the present day, it is definitely shaping the future, but what about our past? The history of the world has been through a lot and now thanks to the Smithsonian’s “Laser Cowboys,” a three-person team who are  3D scanning some of the Smithsonian’s historical collections, some of what our world has been through can be captured and better understood.

The team made it very clear on their recent interview with Engadget.com  that they are NOT 3D scanning the entire Smithsonian collection as some reports had stated, but instead are choosing to do a select number of 3D scans.

So far, the team has done several sacns for the museum. With a list that includes orchids, gunboats, the first aircraft to ever fly, and various parts of Abraham Lincoln’s body, the scans are used for education, scientific research, and for public interest availability.

Some of the 3D prints have been on exhibit already like Abraham Lincolns head. 3D scanning affords the opportunity to create representation of an object without actually touching them.

The way a 3D laser scan works is a laser beam bounces off of an object and back onto a sensor. It captures about a million points per second, which then captures a 3D spherical snapshot of an object. Many scan positions are needed for things like a dinosaur skeleton with so much detail.
