Detailed Description

Handles the creation and updating of DetectionsPerceptions instances from sensor_msgs::msg::Image messages.

This class provides methods to register subscriptions to image topics, decode incoming messages into cv::Mat using cv_bridge, and update target DetectionsPerceptions instances.

Member Function Documentation

cycle_rt()

bool cycle_rt ( std::shared_ptr< NavState > nav_state )

overridevirtual

Run one real-time sensor processing cycle.

This method is called by the SensorsNode before executing its cycle_rt. Here the handler should update the NavState with the sensor data. If new data arrived before this call and the state is updated, it must return true.

Parameters

nav_state

Pointer to the NavState to store the sensor data.

Returns

True if new data was stored (to trigger processing).

Reimplemented from PerceptionHandler.

on_initialize()

void on_initialize ( )

overridevirtual

Optional post-initialization hook for subclasses.

Here, the handler must reserve memory to store the perception data and create any Subscription or similar objects to read the data.

Reimplemented from PerceptionHandler.
