智能手机镭射配件直接测量照片物体真实大小

新华网12月25日电 据科技博客网站Gizmodo报道，一款带有镭射、3D罗盘等高端装置在内的手机配件Spike将于明年5月上市，届时只需拍一张照片就能知道图中物体的真实尺寸了。

一想到翻修房子的打磨、油漆还有诸多拆拆补补很多人就头疼，不过最讨厌的部分要数拿着卷尺满屋子跑来跑起丈量尺寸。如果你愿意挤出560美元，就可以省去这么多麻烦事了，翻修房子就会变得易如反掌，像变魔术一样。这是一个什么样的神奇工具呢？是一个叫做Spike的智能手机配件，带有镭射功能、GPS定位以及其他测量照片中物体实际尺寸的工具，非常之神奇吧？

Spike这个小部件依靠蓝牙功能与你的智能手机相连，不需要任何接口或端口连接，只要你的手机带有GPS功能，Spike都能很好地与苹果iOS和安卓系统“合作”。Spike自带镭射功能，3D罗盘，以及可充电池，它能够测量6到600英尺范围内所有物体或结构的大小和尺寸，而且相当精确。

相当精确，也就是说还是有误差了，Spike可以精确到8英寸左右，小编发现屋里距离越近，测量数据越准确。Spike真的是一个非常神奇的装置，它除了可以测量实物的大小以外，还能测量你所拍摄的任何一张照片上的物体的真是大小，即使它们重叠在一起。此外，用户还能利用Spike测量的数据在SketchUp里构建3D模型。

明年5月，Spike将会发货，只有那些提前订货的人们才能收到第一批货物呦。届时，你将省去拿着卷尺难以测量巨型或远距离物体之苦啦。

This Laser Smartphone Add-On Accurately Measures Everything In a Photo

Forget the sanding, the painting, and all the construction; the worst part of a renovation is having to use a tape measure to size up a room. But if you\'re willing to cough up $560, there\'s now a much better way that almost sounds like magic. It\'s a smartphone accessory called theSpike that uses lasers, GPS, and other sensors to automatically measure everything in a photo you take. Say wha?!

Since it relies on a Bluetooth connection to your smartphone, instead of interfacing with ports or any of that nonsense, the Spike will play happily with iOS and Android hardware—as long as they include GPS capabilities. The device itself features a laser, a 3D compass, and its own rechargeable battery, and uses all of this to create a fairly accurate guesstimate of the size of objects or structures anywhere from six to 600 feet away.

There is a trade-off, of course. By "fairly accurate guesstimate" we mean the Spike is accurate to plus or minus eight inches, and we assume the closer an object is, the better chance it will have of gauging its size. That being said, it still seems like a wonderful contraption, especially since the dimensions for given objects in a scene are automatically overlaid on the photo you snap. And, you can export the measurements and automatically create a 3D model in SketchUp.

So come May of next year when the Spike will hopefully be shipping to those who\'ve pre-ordered, you\'ll finally be able to replace that tape measure that\'s a giant pain for measuring larger distances. Good riddance. [ikeGPS via Gizmag]
