Position

Position represents the location of a marker in 3D space, relative to the camera.

These properties can be accessed as follows:

distance

The distance between the camera and the centre of the marker, in millimetres.

horizontal_angle

Horizontal angle from the centre of the camera’s view to the marker, in radians. Ranges -π to π. Directly in front is zero, positive to the right.

vertical_angle

Vertical angle from the centre of the camera’s view to the marker, in radians. Ranges -π to π. Directly in front is zero, positive values upwards.

markers = robot.camera.see()

for marker in markers:
   print(marker.position.distance)
   print(marker.position.horizontal_angle)
   print(marker.position.vertical_angle)
