Lightbar Curved Guidance Graphics
Lightbar Curved Guidance Graphics
Fieldware’s two curved guidance techniques employ a lightbar text display graphic that aids the
operator when navigating parallel to a curved swath. The X-Track LED method that is employed in
Parallel mode is also employed when driving curved guidance.
A projected swath-path graphic is displayed in the text display area of the lightbar, see Figure 4-
35. This projected path is made up of four horizontal bars. The bottom bar is closest to the vehicle
and the top bar is the path furthest away. The width of the bars decrease as they move away from
the vehicle. This adds a perspective view to the path ahead of the vehicle. The projected distance
the first bar is from the front of the vehicle is based on the vehicle speed. The lightbar in Figure 4-
35 informs the user to drive straight, and there are no turns approaching. In Figure 4-36 the light-
bar indicates the vehicle is approaching a turn to the right. The X-Track LEDs indicate that the
vehicle is slightly to the right of the guideline. Lightbar X-Track LEDs were set up in Swath mode.
Therefore the user must correct to the left to get back on line. The X-Track LEDs do not provide
any information relating to the curved path ahead of the vehicle, they only indicate where the vehi-
cle is with respect to the guideline at the current vehicle location.
