recognize and localize an object in 3D Point Cloud scene using VFH - SVMs based method and 3D-CNNs method

OBJECT DETECTION AND RECOGNITION IN 3D Point Cloud scene

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

Training the classifier

rosrun robot_vision trainer.py

To run package

roslaunch robot_vision robot_vision3.launch

3d_object_recognition's Issues

rosrun robot_vision trainer.py

this gives Error Robot_vision not found. Is anything Else we have to do before running it.

catkin_make error

The following problem occurred after running catkin_make
error: ‘cv::ml::SVM::Types’ is not a class or namespace
SVMclf->setType(cv::ml::SVM::Types::C_SVC);

And I use opencv3.0.0.I found this version has this class.
What should I do?

SVMclassifierAction.h not found

greeting everyone..
i have an issue that SVMclassifierAction.h not found. So, we can't run this repository. can you share SVMclassifierAction.h? thank you for your attention
