    In photography, the field of view is that part of the world that is visible through the camera at a particular position and orientation in space; objects outside the FOV when the picture is taken are not recorded in the photograph.

  3. 摄像头参数介绍 ———— 视场角(FOV) - CSDN博客

    Oct 24, 2022 · 本文介绍了FOV(视场角)的概念,包括水平视场角(HFOV)、垂直视场角(VFOV)和对角视场角(DFOV)。 不同焦距影响视场角大小,焦距越长,视场角和视野范围越小。 同时,文章列举了不同镜头类型的视场角范围及其适用场景,如标准镜头、远摄镜头、广角镜头、超广角镜头和鱼眼镜头。 摘要生成于 C知道 ,由 DeepSeek-R1 满血版支持, 前往体验 > FOV的全称是Field of View (视场角)。 如下图所示,根据摄像头的 成像 原理的情况来看,每 …

  4. 摄影知识:解密视场角d、h、v的含义-CSDN博客

    Jul 6, 2023 · 视场角又分为水平视场角、垂直视场角和对角线视场角,简称为d、h、v。 那么,这三个视场角具体是什么意思呢? 下面我们来一一解密。 一、水平视场角d. 水平视场角d是指相机镜头能够拍摄到的水平范围,通常以度数表示。 例如,一个50mm镜头的水平视场角为39.6度。 也就是说,这个镜头能够拍摄到左右各19.8度的范围。 水平视场角d在摄影中非常重要,因为它决定了我们拍摄到的画面范围。 如果我们想要拍摄一张宽广的风景照,就需要使用具有较大水平视 …
