Modules

TrafficLightsPerceptionComponent

apollo::perception::onboard::TrafficLightsPerceptionComponent

Input

Name	Type	Description	Input channal
msg	apollo::drivers::Image	camera sensor image	/apollo/sensor/camera/front_6mm/image /apollo/sensor/camera/front_6mm/image
hd-map	apollo::perception::map::HDMapInput	HD map	-

>Note: Image data from driver. The default trigger channel include /apollo/sensor/camera/front_6mm/image and /apollo/sensor/camera/front_12mm/image. The detailed input channel information is in modules/perception/traffic_light_region_proposal/conf/traffic_light_region_proposal_config.pb.txt file.

Output

Name	Type	Description	Output channal
frame	apollo::perception::onboard::TrafficDetectMessage	trafficlight message	/perception/inner/Detection

>Note: The output channel is structure type data. The message is defined in the modules/perception/common/onboard/inner_component_messages/traffic_inner_component_messages.h file. The output channel message data can be subscribed by components in the same process.

How to Launch
