SAL3D > LENS DISTORTION TOOL

The Lens Distortion Tool is a module allowing the correction of the distortion introduced by the camera lenses.

The tool is able to compute the parameters from either an image of a checker board or an image of a grid of dots.

The lens distortion tool allows to obtain a Lens Distortion model, that can be further used in SAL3D metric calibrations (both Metric and Angular). After that, the metric configuration obtained can be use to directly convert distorted RangeMaps to undistorted COPs.

The Lens Distortion Tools contains two different distortion models. A simpler one, allowing a fast correction, and an advanced one handling complex lens models such as Scheimpflug.

In both cases, user can calibrate by using dots and chessboard patterns.
