Smartphone new ways: for 3D measurement camera

 There are a lot of smart phone usage, such as photographs, browse the web, and so on, but you thought it could be used as a measuring instrument it? 
　　 , researchers from Carnegie Mellon University say they have developed a new measurement method, as long as the object to be measured before waving a smart phone, you can know the size and shape of the object (I do not blind, can not see how things shape your own measurements ).

　　The researchers said that the main advantage of the method is the measurement of the smartphone camera and its built-in sensors to complete, although the relative professional measuring instruments, the smart phone's sensors are not particularly accurate, but they can be calibrated. 

　　Taking measurements, you need to move the smartphone, but the situation can not arise motion blur. It is understood that, by this measurement approach, researchers succeeded in half millimeter accuracy measurement of distances between the pupils of a person. Professor Simon Lucey Carnegie Mellon University Robotics Research Laboratory, said they never thought such a cheap sensor to complete such precise measurements.

　　Although this study seems a bit nonsensical, but in terms of virtual shopping smart glasses of great significance, will be able to know the exact size of the sweep swept away they want to buy something, think about it is very convenient. In addition, this study if with driverless cars, but also able to simulate the testing of indoor and outdoor scenes.
