一种精确的相机景深计算方法

摘要

首先给出了传统的景深计算公式及其推导过程,并对其进行了深入分析,然后通过光学系统成像原理推导出景深的精确计算公式,并将其和传统的景深计算公式进行了深入的比较和分析,最后从计算机视觉角度阐述了景深计算公式的优点.%This paper first presents the traditional depth calculation formula and its derivation process,and has carried on the thorough analysis,accurate calculation formula and then through the optical system imaging principles derived from the depth of field,and the depth of field and the traditional calculation formula of in-depth comparison and analysis,the advantage from the angle of computer vision described the calculation formula of the depth of field.
