Function Documentation

LidarTemplate ROS2::LidarTemplateUtils::GetTemplate

(

LidarTemplate::LidarModel

model

)

Get the lidar template for a model.

Parameters

model

lidar model.

Returns

the matching template which describes parameters for the model.

AZStd::vector<AZ::Vector3> ROS2::LidarTemplateUtils::PopulateRayRotations

(

const LidarTemplate &

lidarTemplate

)

Compute ray Rotation angles based on lidar model.

Parameters

lidarTemplate

Lidar model to use. Note that different models will produce different number of rays.

Returns

Ray rotations angles as Euler angles in radians.

AZStd::vector<AZ::Vector3> ROS2::LidarTemplateUtils::RotationsToDirections	(	const AZStd::vector< AZ::Vector3 > &	rotations,
		const AZ::Vector3 &	rootRotation
	)

Compute ray directions from rotations.

Parameters

rotations	Rotations as Euler angles in radians to compute directions from.
rootRotation	Root rotation as Euler angles in radians.

Returns

Ray directions constructed by transforming an X axis unit vector by the provided rotations.

size_t ROS2::LidarTemplateUtils::TotalPointCount

(

const LidarTemplate &

t

)

Get total point count for a given template.

Parameters

t	lidar template.

Returns

total count of points that the lidar specified by the template would produce on each scan.
