perception-camera-location-estimation

Introduction

The current module is able to calculate the rotation angle of the target in the camera coordinate system based on the network predicted 2D target box information, 3D observation angle information, 3D dimension information, and camera internal parameters Then, combined with the obstacle size template, the module solves the target 3dbbox, and converts the coordinates to the world coordinate system.

Module

CameraLocationEstimationComponent

apollo::perception::camera::CameraLocationEstimationComponent

Input

Name	Type	Description	Input channal
frame	apollo::perception::onboard::CameraFrame	camera frame message	/perception/inner/Detection

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

Output

Name	Type	Description	Output channal
frame	apollo::perception::onboard::CameraFrame	camera frame message	/perception/inner/location_estimation

>Note: The output channel is structure type data. The message is defined in the modules/perception/common/onboard/inner_component_messages/camera_detection_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_location_estimation/conf/camera_location_estimation_config.pb.txt file.
