Range Based Sensor Simulation [omni.isaac.range_sensor]

This extension provides a set simulated range based sensors like lidar, ultrasonic, generic and interfaces to access them in the simulator.

Lidar Sensor

This submodule provides an interface to a simulated lidar sensor. A simplified command is provided to create a lidar sensor in the stage:

commands.RangeSensorCreateLidar(parent=None, min_range: float = 0.4, max_range: float = 100.0, draw_points: bool = False, draw_lines: bool = False, horizontal_fov: float = 360.0, vertical_fov: float = 30.0, horizontal_resolution: float = 0.4, vertical_resolution: float = 4.0, rotation_rate: float = 20.0, high_lod: bool = False, yaw_offset: float = 0.0, enable_semantics: bool = False)

Commands class to create a lidar sensor.

Typical usage example:

result, prim = omni.kit.commands.execute(
    "RangeSensorCreateLidar",
    path="/Lidar",
    parent=None,
    min_range=0.4,
    max_range=100.0,
    draw_points=False,
    draw_lines=False,
    horizontal_fov=360.0,
    vertical_fov=30.0,
    horizontal_resolution=0.4,
    vertical_resolution=4.0,
    rotation_rate=20.0,
    high_lod=False,
    yaw_offset=0.0,
    enable_semantics=False,
)

Once a lidar sensor is in the stage you can use this interface to interact with the simulated lidar data. You must first call the acquire interface function. It is also recommended to use the is_lidar_sensor function to check if a lidar sensor exists at the given USD path

from omni.isaac.range_sensor._range_sensor import acquire_lidar_sensor_interface
lidar_sensor_interface = acquire_lidar_sensor_interface()
if lidar_sensor_interface.is_lidar_sensor("/World/Lidar"):
