Rotate
The rotation angle (in radians) of the coordinate system where the demonstration point is
located relative to the coordinate system where the running point is located. When the
rotation θ is a positive value, after the X axis of the coordinate system where the
demonstration point is located rotates θ counterclockwise, its X axis is consistent with the X
axis of the coordinate system where the running point is located. When the rotation θ is a
negative value, the demonstration point is located. After the X axis of the coordinate system
rotates clockwise by -θ, its X axis is consistent with the X axis direction of the coordinate
system where the operating point is located.
Scale
The unit length in the coordinate system where the demonstration point is located
corresponds to the number of pixels in the coordinate system where the running point is
located.
Skew
The difference between the Y-axis rotation angle and the X-axis rotation angle of the
coordinate system where the demonstration point is located (in radians).
Aspect
The ratio of the Y-axis zoom amount to the X-axis zoom amount of the coordinate system
where the demonstration point is located.
CalibBoard Calibration
The calibration board calibration is divided into four types, including checkerboard, circle grid
board, Hikrobot I, and Hikrobot II.
Take the checkerboard as an example. After Inputting the checkerboard grayscale image and its
dimension parameters, the software will calculate the mapping matrix, calibration error, and
calibration status between the image coordinate system and the checkerboard physical coordinate
system. This tool can generate one calibration file to be used by the calibration conversion. By
clicking Creating Calibration File, you can select the path for saving created calibration file, as
shown below.
