Cannot Create a KDTree with an empty input cloud

Opened this issue 6 years ago · 1 comments

Hi,
I am receiving the following error messages when running ver 3:
[pcl::KdTreeFLANN::setInputCloud] Cannot create a KDTree with an empty input cloud!

I am using a kinect which publishes its point cloud and image data to topics that will be subscribed by the code. 2d darknet_ros works perfectly fine.

Just subscribe to the point cloud topic and see if any data is coming. Whats your setup by the way ? Are you running this on bag file ?
