CreateChessboardMatrix

Basic

Module: OpenCV

Creates simple array with object points.

Name Type Range Description
Input value inBeginX Integer X of top left corner
Input value inBeginY Integer Y of top left corner
Input value inStep Real Distance between adjacent points
Input value inWidth Integer 0 - Number of columns
Input value inHeight Integer 0 - Number of rows
Input value inRepeats Integer 0 - Number of copies of the pattern returned
Output value outPoints Point3DArrayArray

Examples

When used with inWidth = 2, inHeight = 3, inRepeats = 1 and inStep = 1, the following Point3D array will be generated: 
Point3D(X: 0,000, Y: 0,000, Z: 0,000)
Point3D(X: 1,000, Y: 0,000, Z: 0,000)
Point3D(X: 0,000, Y: 1,000, Z: 0,000)
Point3D(X: 1,000, Y: 1,000, Z: 0,000)
Point3D(X: 0,000, Y: 2,000, Z: 0,000)
Point3D(X: 1,000, Y: 2,000, Z: 0,000)

Remarks

This filter is not a wrapper of an OpenCV function, but it is an utility function, which allows for easier usage of some OpenCV function wrappers.

Complexity Level

This filter is available on Basic Complexity Level.
