是否有办法显示,幕后摄像机在完全屏幕上捕获哪些东西,从而造成对看到的屏幕的幻觉? 它不需要完美无缺,必须有足够的说服力,只有微薄的滞后才能有所改变。
Is it possible to create such an effect using phone camera? If yes, how can the effect be achieved? (as in what transformations to apply etc.)
(我已知道如何
<><>Edit>: 现在,我也知道,已经这样做了:http://gizmodo.com/5587749/the-samsung-galaxy-s-goes-see through, 但是,我仍然不知道如何适当做到这一点,我知道审判和错误是一条途径,而另一种做法是计算用户在电话时应当看到的内容。 我认为,有一些因素涉及: 因此,我并不认为这个问题有简单的解决办法,如果不如此,请回答。 帮助 Shobhit,
您可使用标准3D投射线 数学,在显示的后面部分照相照相图像上投射;通过假定照相机从后方照相机的某个特定深度,并通过向观察员提出特定观点,您可以管理。
You can improve on this by looking for faces/eyes using the frontside camera. You can get a rough estimate of the the viewing distance from the eye spacing, and assume a viewer position midway between the eyes. Of course, this only works for one viewer at a time (e.g., if your face tracker finds multiple faces, you can select one of them).
此外,通过校准摄像机和屏幕,使你能够从一对二者的肤色和光明相匹配,你可以改善幻觉。
