论文摘要
智能手机是全球大部分学生的强大学习帮助。手机的摄像机可用于多种学习目的,除了其拍照的明显目的。如果可以确定摄像机镜头的焦距,则可以使用光学器件中的几个实验。在最近的一些作品中,已经讨论了焦距的确定方法。当对象的真实图像是由已知焦距的镜头形成的,如果已知另一个镜头,则可以确定对象的距离或横向放大倍率。在这项工作中,我们表明我们可以通过从两个位置拍摄横向横向大小和物体的距离,并沿着相机的视线距离距离。
A smartphone is a powerful learning aid in the hands of a large section of students around the world. The camera of the phone can be used for several learning purposes apart from its obvious purpose of photographing. If the focal length of the lens of the camera can be determined, several experiments in optics can be performed with it. In some recent works, the method of determination of the focal length has been discussed. When a real image of an object is formed by a lens of known focal length, one can determine either the distance or the transverse magnification of the object if the other is known. In this work we have shown that we can determine both the transverse size and the distance of an object, by photographing it from two positions, separated by a distance along the line of sight of the camera.
