Translation X/Y: it is the calibration parameters by calculation. The origin of the world
coordinate system is mapped to image coordinates system, and obtain the coordinate X/Y.
Rotation: the rotation angle (unit: radians) of the world coordinate system relative to the
image coordinate system. When rotating θ is positive, and after the X-axis of the world coordinate
system rotates counterclockwise θ, its X-axis is consistent with the X-axis direction of the image
coordinate system θ. When it is negative, and after the X-axis of the world coordinate system rotates
clockwise θ, its X-axis is consistent with the X-axis direction of the image coordinate system.
Scale: the unit length in the world coordinate system corresponds to the number of pixels
in the image coordinate system.
Chamfer: difference between Y-axis rotation angle and X-axis rotation angle of world
coordinate system (unit: radians).
Aspect Ratio: the ratio of Y-axis scaling to X-axis scaling in the world coordinate system.
Scale Transformation
The tool of scale transformation is used to convert pixel units like distance and width to physical
units. For specific use, you only need to load the calibration file, set the distance to be converted,
and subscribe refresh signal, as shown below.
