一种增加反射元件提高景深的自动聚焦装置及自动聚焦方法
Abstract:
本发明公开了一种增加反射元件提高景深的自动聚焦装置及自动聚焦方法，包含平台(1)，镜头(2)，反射元件(3)，图像采集设备(4)，计算机处理系统(5)，以及平台位置控制器(6)；所述平台(1)可沿X、Y、Z三个坐标轴移动；所述图像采集设备(4)中设置一个图像采集传感器(7)；所述反射元件(3)的法线与镜头的光轴形成倾角(θ)的范围为39.5°
Abstract(English):

The invention discloses an automatic focusing device and an automatic focusing method for increasing the depth of field by adding a reflective element, comprising a platform (1), a lens (2), a reflective element (3), an image acquisition device (4), a computer processing system (5), and a platform position controller (6). The platform (1) is movable along three coordinate axes of X, Y and Z; An image acquisition sensor (7) is arranged in the image acquisition device (4); The normal of the reflective element (3) forms an inclination angle (theta) with the optical axis of the lens in the range of 39.5 DEG
