The field of view (FOV) is the angular extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors, it is a solid angle through which a detector is sensitive to electromagnetic radiation .

在光学仪器中，以光学仪器的镜头为顶点，以被测目标的物像可通过镜头的最大范围的两条边缘构成的夹角，称为视场角。 本期我们将介绍视场角的相关知识，了解它与镜头、 图像传感器 之间的关系。 视场角，与两件事有关，镜头的焦距以及图像传感器的尺寸。 假定镜头焦距相同，图像传感器的尺寸越大，视场角也就越大，反之亦然。 镜头的焦距表示镜头与图像传感器上聚焦图像之间的距离。 当光通过镜头时，它要么会聚集 （正焦距），要么会发散（负焦距），但在相机 …

Knowing the FOV will help you know exactly what focal length will work for you. Let’s take a look at just what field of view is, how it relates to lens focal length, and how it ultimately can guide you in knowing which lenses are best for which situations.

This diagram is the basis of Field of View and Depth of Field calculations. The half angles form geometry's Similar Triangles from the equal angles on each side of the lens. The /2 cancels out on both sides.

FOV is the range of the observable world visible at any given time through the human eye, a camera viewfinder or on a display screen. It refers to the coverage of an entire area rather than a single, fixed focal point. FOV also describes the angle through which a …

2024年11月27日 · Field of View（FOV）是指视野的范围，通常用角度来表示。在计算机图形学中，FOV是指从摄像机或观察者位置到场景中可见区域的角度范围。 FOV的大小会影响到图像的视觉效果和交互体验。较大的FOV会使图像看起来更...

By focusing the lens for different working distances (WDs), differently sized field of view (FOV) can be obtained, though the viewing angle is constant. AFOV is typically specified as the full angle (in degrees) associated with the horizontal dimension (width) of …

Field of View (FOV) (FOV): The viewable area of the object under inspection. This is the portion of the object that fills the camera’s sensor. This area is commonly reduced to the horizontal (HFOV) (HFOV) or vertical (VFOV) (VFOV) dimension for ease of calculation.
