How to measure field of view
In remote sensing, the solid angle through which a detector element (a pixel sensor) is sensitive to electromagnetic radiation at any one time, is called instantaneous field of view or IFOV. A measure of the spatial resolution of a remote sensing imaging system, it is often expressed as dimensions of visible ground area, for some known sensor altitude. Single pixel IFOV is closely related to concept of resolved pixel size, ground resolved distance, ground sample distance and modulation … WebCalculating the Diameter of the Field of View. One part of our exercise involves the direct measurement of the diameter of the field of view using a clear ruler at 40x and 100x. …

WebField of view defines the maximum area of a sample that a camera can image, determined by the focal length of the lens and the sensor size. Sensor size is … WebThe goal is to measure a specified distance in your photo and find the length in pixels. In our case we will measure the distance between two fence lines on a property. Once we know the pixel distance we will calculate the ground sample distance (GSD) based on the camera's parameters.
WebIt’s simple: field of view informs us as to how much of a scene a lens can see. In other words, it’s a more informative benchmark regarding what you can photograph with the specific camera and lens you’re using.
