Horizontal angle (result): -
Vertical angle (result): -
Results are approximate!
You can define focus distance of lens if You can get width and height picture what do You want, if You know distance between camera and target in second calculator. You need size of tagret place and distance between camera and target and You are looking for optimal lens (angle). Fill CCD size and data about target place (width and height) in meters and distance of target in meter. If You fill width data first then calculator will fill data of height automatically.
