Detailed Description

Represents a single IMU perception from a sensor.

Inherits from PerceptionBase and stores a sensor_msgs::msg::Imu message.

Member Function Documentation

consume_new_data()

bool consume_new_data

(

)

Atomically reads and clears new_data.

Returns

The value of new_data before it was cleared.

operator=()

IMUPerception & operator=

(

const IMUPerception &

other

)

set_data()

void set_data	(	const sensor_msgs::msg::Imu &	msg,
		const rclcpp::Time &	msg_stamp,
		const std::string &	msg_frame_id )

Atomically overwrites stamp/frame_id/data/valid from the subscription callback.

Guards against a concurrent copy (e.g. via NavState::get_safe()) observing a partially-updated object while this handler's RT-thread callback is writing.

supports_msg_type()

bool supports_msg_type ( std::string_view t )

static

Returns whether the given ROS 2 type name is supported by this perception.

Parameters

t	Fully qualified message type name (e.g., "sensor_msgs/msg/Imu").

Returns

true if t equals "sensor_msgs/msg/Imu", otherwise false.

Member Data Documentation
