Cannot create a KDTree with an empty input cloud!

[Minsu-Kim1822]

Hi all,

I try to generate a map with LIO-LIVOX using HAP.
I ran my custom rosbag files, and it works well with this error.
I think memory leak is occurred due to this problem, but I do not have an idea to solve this problem

Any solutions?

Me too

just change

kdtreeNonFeatureFromLocal->setInputCloud(laserCloudNonFeatureFromLocal);

to

  if(!laserCloudNonFeatureFromLocal->empty())
    kdtreeNonFeatureFromLocal->setInputCloud(laserCloudNonFeatureFromLocal);

@whyscience
Thank you for your reply, but it does not work for me

[whyscience]

you can add log to all the setInputCloud used, then use if(!cloud->empty()) to avoid the ERROR

@whyscience , Thanks it works! :)

Btw, due to the memory increases exponentially, it suddenly shut downed itself.
Do you have any idea or experienced such things?

This error is because there is no assigned value to 'laserCloudCornerLast' variable in <Estimator.cpp> .
There is no corner related code in this repository, so you can just use FeatureExtract_with_segment function instead of FeatureExtract_with_segment_hap function.

using mid360 I get:

I have the same problem in mid360. Have you tried in outdoor scene？

No I haven't. Indoor only.

Hello, I have the same problem about HAP, have you solved it now?

thx, it works!

Hi. What do you mean by this? If there is no assigned value to 'laserCloudCornerLast' Variable, then how does that link with the FeatureExtract_with_segment function. Could you explain more of how to resolve the issue? Thank you :)

I am getting the same error can u please explain what changes to be done in code?

[abhishekt711]

I have used the same function as u said but after some frame process has died
