Dot Pattern

Distorted image of a dot pattern.

The Dot Pattern Module can be used to analyze images of a dot pattern target. A dot pattern target consists of a Cartesian-grid of circular gray dots. The Dot Pattern Module processes images of dot pattern targets and estimates the optical distortion and SMIA TV distortion as well as the lateral chromatic aberration. of the optical system from these images. The methods used in the Dot Pattern Module for detecting and processing the dots are an implementation of the algorithms as described in the CPIQ documents on lateral chromatic aberration and distortion.
