Calculate Depth of Focus

The calculator below estimates the recommended maximum aperture (minimum $f$-number). This value should be used when adjusting settings for Zivid cameras, in order to stay within an acceptable level of blur.

Input parameters are:

• Camera model

• Closest working distance (in millimeters)

• Farthest working distance (in millimeters)

• Acceptable blur radius in pixels

Inputs

One+ Small
One+ Medium

Outputs

Description:

Input the desired working distance and camera model. The calculator will estimate the minimum recommended Aperture value to use for the given working distance.

Expert mode:

Use "Acceptable blur radius" to adjust the blur tolerance. Larger blur radius will cause the the point cloud to be more noisy, but will still give acceptable results in most applications.
