Detailed Description

Allowed values for the calibration mode.

Member Data Documentation

Advanced

int eVision.ECalibrationMode.Advanced = 8192

static

Advanced calibration mode.

This mode is capable of handling larger amount of distortion compared to the Radial mode.

Anisotropic

int eVision.ECalibrationMode.Anisotropic = 8

static

The physical size of the pixels differ horizontally and vertically.

(Beware there is a restriction pertaining to the allowed image anisotropy. The resulting pixels aspect ratio should be in the range [-4/3, -3/4] (or [3/4, 4/3]), otherwise the calibration process could fail).

Bilinear

int eVision.ECalibrationMode.Bilinear = 256

static

This mode can not be combined with other calibration mode.

The bilinear calibration is based on a first order polynomial approach.

Inverse

int eVision.ECalibrationMode.Inverse = 2

static

The ordinate (y) axis points downwards instead of upwards.

Quadratic

int eVision.ECalibrationMode.Quadratic = 512

static

This mode can not be combined with other calibration mode.

The quadratic calibration is based on a second order polynomial approach.

Radial

int eVision.ECalibrationMode.Radial = 64

static

The lens introduces some amount of radial distortion.

Raw

int eVision.ECalibrationMode.Raw = 1

static

No calibration at all.

Scaled

int eVision.ECalibrationMode.Scaled = 4

static

The pixels are assigned a physical size.

Skewed

int eVision.ECalibrationMode.Skewed = 16

static

The abscissa (x) axes make an angle with the image edge.

Tilted

int eVision.ECalibrationMode.Tilted = 32

static

The field-of-view plane is not perpendicular to the optical axis.
