Event-camera field of view

Estimate horizontal and vertical FOV from pixel pitch, array size, lens focal length, and distance from the camera. Presets match jAER chip classes. Results use jAER EngineeringFormat (SI prefixes).

Inputs

Camera

Lens focal length (mm)

Pixel pitch (µm)

Array width (pixels)

Array height (pixels)

Distance from camera (m)

Results

Pinhole model, same as jAER Steadicam / AbstractMotionFlowIMU:
FOV = 2 atan(sensor_mm / (2 f_mm)) · deg/pixel = atan(pitch_mm / f_mm) · scene_m = D_m × sensor_mm / f_mm
