Sensor angular alignment

A method comprising:

• acquiring, via a network interface, a translational vector, a first calibration point location and a second calibration point location;
• determining an expected rotational orientation in response to the translational vector, the first calibration point location and the second calibration point location;
• capturing, by a camera, an image of a first calibration point and a second calibration point;
• determining, by an image recognition algorithm, a first position of the first calibration point and a second position of the second calibration point in response to the image;
• calculating a calculated rotational orientation in response to the first position of the first calibration point and the second position of the second calibration point;
• determining a calibration value in response to the calculated rotational orientation;
• storing the calibration value in a memory;
• and
