Our lens field calculator is a complimentary web-based design tool for calculating video camera lens field of. Aspect ratio. m = 6. 16:9 (e. Although it can deduce the horizontal/vertical field of view if only the diagonal field of view is privided, it did not correctly do this unless the input projection was "fisheye" or "flat" (rectilinear), because that code was not implemented at the time. This means that if the object in the image above has a HFOV of 40mm and a VFOV of 30mm, then the FOV. The shorter the focal length (e. First, we calculate the value of cathetus o (opposed to angle γ). Field of View is an angle which depends on the focal length and sensor size, but it also computes dimensional Field of View sizes (width, height, or diagonal fields) at some specific distance, like at the subject distance, and another, like at a background distance. 8ft: 1.
