perception-radar-detection

Introduction

The radar detection module detects and tracks obstacles through the radar sensor, then sends them to the multi-sensor fusion module.

The radar detection module receives the radar drive message, which is already include the objects detected and tracked. Even so, the radar module has re-tracked the objects.

Modules

RadarDetectionComponent

apollo::perception::radar::RadarDetectionComponent

Input

Note: Radar data from driver. The default trigger channel is /apollo/sensor/radar/front. The detailed input channel information is in modules/perception/radar_detection/dag/radar_detection_front.dag file.

Output

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/radar_detection/conf/front_radar_detection_config.pb.txt file.

How to run

In most cases, the radar detection module needs to work with the multi-sensor fusion module. If you want to debug the radar module separately and view the detected obstacle information, you can combine the msg_adapter module.

Run the command as follows.

cyber_launch start modules/perception/launch/perception_radar.launch
