Camera Identification Distance Calculator

Computes max identification distance from FoV + sensor pixels + min pixel footprint. Full dome scan time is max(mechanical, camera) where camera time assumes 1 frame per tile. Adds a motion blur limiter (default worst-case lateral motion) using a blur budget as a fraction of the object footprint.

Inputs

Preset: Default

FoV width

deg

FoV height

deg

Top-down visualization uses FoV width only.

Dome scan azimuth

deg

Dome scan elevation

deg

Scan speed (pan)

deg/s

Scan speed (tilt)

deg/s

Tile overlap

Detection FPS

fps

Object speed (worst-case lateral)

m/s

Scan time uses a row-scan pattern: pan across full azimuth for each elevation row, then tilt by one step.

Sensor width

Sensor height

Sensor mm is used to estimate focal length and f-number. Distance math uses FoV (deg) + sensor px.

Scene illuminance

lux

ISO

Shutter fraction

0-1

Target SNR (rough)

ratio

Exposure estimate is approximate. Real results depend strongly on optics transmission, QE/efficiency, and scene.

Lens transmission

0-1

System efficiency

0-1

Blur budget (identify)

% of footprint

Include scan motion blur

Blur budget is applied to the object footprint: allowed blur = blurFrac * min(objPxW, objPxH) at distance D. Default assumes worst-case lateral motion from object only.

Object width

Object height

Assumes object face is roughly perpendicular to the camera axis.

Min pixels (object width)

Min pixels (object height)

Interpret as the minimum pixel footprint to identify the object (model or human).
