LinePrimitive
A primitive representing a series of points connected by lines.
Parent schema
LinePrimitive appears in the SceneEntity message schema.
Schema
| Field | Type | Description |
|---|---|---|
timestamp | time | Timestamp of scan. |
frame_id | string | Frame of reference. |
pose | Pose | The scan origin is defined relative to the frame of reference. Point positions are specified in the x-y plane with respect to this origin. Angles are measured as counterclockwise rotations around the z-axis, with 0 radians aligned with the positive x-axis. |
start_angle | float64 | Bearing of first point, in radians. |
end_angle | float64 | Bearing of last point, in radians. |
ranges | float64[] | Distances of detections from the origin, assumed to be measured at equally spaced angles between the start angle and end angle. |
intensities | float64[] | Intensity of detections. |
