OBJECT DETECTION AND RECOGNITION IN 3D Point Cloud scene

3D_Object_REC

DISCLAIMER: project is still in development stage, I try to keep master branch as updated and functional as possible.

Dependencies

  • ROS Kinetic
  • PCL 1.8
  • Opencv 2
  • Python 2.7
  • Numpy
  • cv2
  • TensorFlow
  • Keras

Nodes

	|-> tf_emitter
	|-> segmentationNode
	|-> classifierNode
	|-> RViz
	`-> pcd_to_pointcloud

tf_emitter

  • publishes world frame for RViz

segmentationNode

  • publishes all the segmented clouds to /pcVector

classificationNode

  • subscribes /pcVector and classifies every segmented pointcloud using 3DCNN and publishes bounding boxes as MarkerArray

Rviz

  • used for visualization

pcd_to_pointcloud

  • to publish scenes for testing

Note

/bin - contains .pcd scenes which are broadcasted
