#科技头条#【把世界装进口袋:手机3D扫描仪】悉尼一小组最近推出了一款小型3D扫描设备,使手机可以扫描周围情景。该设备利用比COMS感光原件敏感两倍的绿色激光扫描物体表面,通过蓝牙与手机相连,同时允许用户创造目标点云以获得清晰细节,其模型数据可被用作3D打印和原型设计等。

The Eora 3D Scanner Can Capture The Very Soul Of An Object

Primitive cultures like my family believe that 3D scanning steals the essence of a person which is why we do not allow binocular vision in my home. The Eora 3D scanner, however, is allowed because it takes 3D scans using a device that is surprisingly simple yet exceedingly complex and only uses one camera.

Created by Rahul Koduri and Asfand Khan of Sydney, Australia the project came about when they were working on concentrating solar rays. They have just launched their product on Kickstarter.

“The eora 3D Scanner was born out of our own need for an affordable and highly-precise 3D scanner,” said Koduri. “We needed to capture the specifications of a reflective parabolic dish that was used to track the sun’s trajectory to improve solar power output. When we originally looked for what was available we were shocked that scanners that are precise to sub-100 microns cost atleast $5000.”

The team began working on an early prototype and realized that they had a real product on their hands.

The system works by scanning the surface a green laser. The laser connects via Bluetooth to your phone camera and allows you to create a point cloud of the object in alarming detail. Best of all the system scans in full color – a unique feature that I haven’t seen in a smaller scanner.

“The eora 3D Scanner has a Green laser, as CMOS sensors in cameras are twice as sensitive to the green spectrum which allows for 3D Scanning in a variety of conditions even outdoors,” said Koduri. “This is due to human beings evolving in green landscapes/brushes, so our eyes are also more sensitive to the green spectrum.”

The models can be used in games, for 3D printing, and for prototyping. One scan the team showed me – an Assassin’s Creed character – was surprisingly detailed for a simple scan. Scans can take as little as 3 minutes in some cases but more complex scans take a little longer. The system includes an automatic turntable to turn the object in space so you can capture all sides at sub-100 micron accuracy.
