It’s the lens focal length combined with the size of your camera’s sensor that determines the camera field of view. The online specifications tell me the horizontal field of view is 47 degrees, and the image size is 640x480. Does this mean that the vertical field of view will be 32. Dec 22, 2008 · Found this thread really useful when I wanted to find a way to fix the horizontal field of view regardless of the aspect ratio of the camera. The FOV measurement is specified in degrees and is typically shown in either Horizontal x Vertical or a diagonal measurement. Just drop it onto your camera and set your fixed horizontal FOV. \$\begingroup\$ @scottbb I am doing some analysis independent of the sensor to use. The field of view is typically expressed in degrees and includes HFOV(Horizontal Field of View), VFOV(Vertical Field of View), and DFOV(Diagonal Field of View). 5), the field of view is twice the size of the sensor. As for the angle of view, you can identify three quantities associated with the field of view: a horizontal length, a vertical length, and a diagonal length. 25mm for the diagonal FOV. Diagonal : Horizontal. 19m Here "frame size" refers to the dimension of the frame in the direction of the FOV, so for 35mm (which is 24mm x 36mm), frame size is 36mm for the horizontal FOV, 24mm for the vertical FOV and 43. So according to HMD Geometry Database Pico 4 has horizontal and vertical fov of 104 degree, and stereo overlap is also 104 degree, so according to me 104 degree of overlap should be considered while calculating diagonal FOV, but when I apply pythagoras theorem Diagonal Fov comes around 147 degree which is way more than the advertised 120 degree FOV, so my question is, If FOV/Degrees measured Angle of View Input: Lens Focal Length F Dimension format D Formula: ((D/2/F)ATAN)2 Dimension D divided by 2 divided by focal length Find ATAN of this value then multiplied by 2 Example 50mm lens mounted on FX (full frame) Dimension of format is diagonal of film or digital sensor FX = 24mm height by 36mm length diagonal of this rectangle = 43.
