# CameraCalibration

Interface between UI, calibration data and running algorithms.

Base class (inherits properties and methods): _[Resource](/python-api/docs/resource#resource)_

## Properties

#### **cameraNames** : _List\[str\]_ _(Read-Only)_

#### **chessSquaresSizeDefault** : _[Vec2](/python-api/docs/vec2#vec2)_

Set chessboard size via total chessboard width and height, e.g. 0.7584 x 0.5688 \[m\].

_Category: Default Settings  
UserName: Chessboard all square size \[m\]_

#### **chessboardSizeDefault** : _[Int2](/python-api/docs/int2#int2)_

Number of black & white squares on the chessboard, e.g. 12x9.

_Category: Default Settings  
UserName: Chessboard size_

#### **chessboardSquareLength** : _float_

#### **intrMatchTolerance** : _float_

Tolerance that determines which intrinsics are considered for a camera \[0-1\].

_Category: Intrinsic Selection  
UserName: Intrinsic match tolerance_

#### **intrMaxError** : _float_

Camera intrinsics with pixel reprojection error above this value are ignored.

_Category: Intrinsic Selection  
UserName: Intrinsic max error_
