新华网8月15日电 据美国科技博客Gizmodo报道，美国国家航空航天局的科学家们正在研制一款能够通过手机测量女性胸部尺寸的APP。
文胸也许是世界上最老的科技发明之一了，它可以追溯到古希腊时期。如今，文胸对于女性来说几乎是每天的必备品，然而有许多研究都表明很多女性穿戴文胸的方式有误。最近，一支由美国国家航空航天局（NASA）的科学家牵头的工程小组开发了一款名为ThirdLove的手机APP，希望仅仅通过iPhone和拍几张照片就改变这一现状。
这款APP目前还处于内测阶段，它的“终极目标”就是让女性不再去内衣店进行胸部尺寸测量（很多女性一辈子都在逃避这一点），而在自家就通过扫描获取自己胸部的尺寸。作为美国国家航空航天局级别的工程师们，其目标就是让测量更加准确。FastCo试用了这款APP，结果表明了它不会满足于一切精确结果以外的东西。
按照指示，我站在镜子前，把iPhone放在肚脐的位置。“把手机右侧底部稍稍抬起”她说，“然后再抬起左侧底部”。之后“再抬起右侧底部。”如此反复大约50次之后，屏幕上出现了“干得棒”的提示，以及一次倒计时。随后，屏幕指示要求我在手机里排列一组盒子，然后放在和胸口齐平的地方。
当你按照手机的要求将自己的尺寸录入软件后，神奇的“文胸魔术”就开始上演了。据参与该软件设计的美国国家航空航天局高级科学家Ara Nefian表示，他们不会透露太多有关这款软件算法的信息。他只是提到设计该软件时“用到了计算机视觉、人体建模及机器学习等多种技术”，并将iPhone作为“定标物体”（calibration object）来测量相机参数。
目前，该APP已经获得560万美元的投资，加上美国国国家航空航天局科学家们的参与，相信其能够获得成功。然而，正如之前提到的一样，这款APP目前还处于测试阶段，对研发者来说还有时间来对其进行调整。相信全世界的“胸”都会对这款软件表示感谢。

A NASA Scientist Made an App Dedicated to More Secure Boobs
Bras are pretty much some of the oldest pieces of tech around—the undergarment can even trace its roots all the way back to the ancient Greece. So as something most women wear nearly every day, it's amazing how many studies have come out claiming that ladies everywhere our wearing their bras all wrong. ThirdLove, a new app headed up by a NASA scientist-led engineering team, hopes to change all that with nothing more than an iPhone and a few snapshots.
Currently still in private beta, the app's ultimate goal is to cut back on the uncomfortable garment store measuring sessions (that many women will probably spend their whole life avoiding) by scanning your bust size in the privacy of your own home. And just as you'd expect from NASA-grade engineering, this thing wants to get it right. FastCo tested the app, and as you can see, the app won't settle for anything less than absolute precision:
As instructed, I stand in front of my mirror with my phone at my belly button. “Slightly raise right end of the phone,” she says. Then “slightly raise left end of the phone.” Then, “slightly raise right end of the phone.” After about 50 more rounds of this, there s a“Good job” and a countdown to the photo. Instructions on the screen ask me to line up a box with the iPhone in the photo and to place a line on my chest. Then the principal voice walks me through the same process for a photo from the sideways perspective.
Once you've perfectly positioned yourself to your iPhone's liking, the better bra magic goes to work. Ara Nefian, the senior scientist with the Intelligent Robotics Group at NASA Ames Research Center who worked on the app, wouldn't get into too many details about their method when prompted by FastCo. He tells them that it "involves several methods of advanced computer vision, body modeling, and machine learning" and uses the iPhone as a "calibration object" to estimate the camera's parameters.
With $5.6 million raised in investments and a real, live NASA scientist on board, it certainly seems like it should work. As previously mentioned, though, the app is still in beta, so there is still time for its makers to change their minds—the boobs of the world would be forever grateful.
