Introduction

The function of camera tracking module is to process the camera detection obstacles by using the omt obstacle tracker, and output the tracked obstacles for following multi sensor fusion.

modules

CameraTrackingComponent

apollo::perception::camera::CameraTrackingComponent

input

Name	Type	Description	Input channal
frame	apollo::perception::onboard::CameraFrame	camera detection frame	/perception/inner/location_refinement

>Note: The input channel is structure type data. The default trigger channel is /perception/inner/location_refinement. The detailed input channel information is in modules/perception/camera_tracking/dag/camera_tracking.dag file. By default, the upstream components of the messages received by the component include camera_location_refinement and camera_detection_single_stage.

output

Name	Type	Description	Output channal
frame	apollo::perception::onboard::SensorFrameMessage	camera tracked obstacles	/perception/inner/PrefusedObjects

>Note: The output channel is structure type data. The message is defined in the modules/perception/common/onboard/inner_component_messages/inner_component_messages.h file. The output channel message data can be subscribed by components in the same process. The detailed output channel information is in modules/perception/camera_tracking/conf/camera_tracking_config.pb.txt file.

how to launch module

1. modify the file: modules/perception/camera_tracking/dag/camera_tracking.dag

• config_file_path: the path of module config files
• reader channel: the channel name of input message

1. modify the file: modules/perception/camera_tracking/conf/camera_tracking_config.pb.txt

• output_channel_name: the channel name of output message
• image_width and image height: the size of input images
• gpu_id: the gpu id
• plugin_param.name: the name of used camera tracker
• plugin_param.config_path: the config path of used camera tracker
• plugin_param.config_file: the config name of used camera tracker

1. run mainboard -d modules/perception/camera_tracking/dag/camera_tracking.dag
