Coordinate Systems
Your Cognex vision software defines two coordinate systems in connection with displacement sensors:
Coordinate System
Description
Sensor 3D Space
Physically accurate / right-handed 3D coordinate system rigidly affixed
to the sensor.
Units: mm
Image 3D Space
Left-handed, the origin is at the upper-left corner of first pixel in image.
Units: pixels (X/Y) pixel values (Z)
Sensor 3D Space
The Sensor 3D coordinate system is defined by:
l
The laser plane (X and Y axes)
l
The extrapolated position of the mounting pins on the sensor hardware:
The projected laser plane defines the X-axis, while the Y-axis is perpendicular to the X-axis:
