On clean test data I have Iterative closest point working, but giving strange results(although I may have implemented it incorrectly...) I have pcl::estimateRigidTransformation working, and it seems better, although I assume will deal worse with noisy data. My question is: The two clouds will be noisy, and although they should contain the same points, there will be some discrepancies. What is the best way to

I need to create some project PCL of xamarin forms, help me. 回答1: Since a recent version the templates replace the PCL library with a .NET Standard library. And I suggest that you stick with it, as it will be the future. You should be able to create a PCL library if you really want to and make it work. Also, as a workaround, you could create the project on

In other words, I need to upsample the point cloud for surface reconstruction of the 3D point cloud. I followed this link, but could not understand the method. Is there an easy way to do that ? Thanks in advance. 回答1: An alternative resource with some simpler code using the Point Cloud Library is available at the following link: http://pointclouds.org/documentation/tutorials/resampling.php I would suggest starting there. Note that the code just calls an

I am working on a project to port Mono.Data.Sqlite to Windows Phone and Windows Store, but of course this requires System.Data to be ported as well. I decided to use PCLs as this removes the need for separate assemblies for the platforms (I am also checking out Silverlight, but this is not a priority) In doing this, I have managed to get most of the functionality across except for one type - DBNull :( This is where the problem is, WP and SL have the DBNull

(i checked on profile104 and there is no System.Threading.Tasks namespace, but on profile 131 there is...) So, is there a way to use mvvmcross with TPL? Thanks. 回答1: There are several ways to use TPL with portable class libraries. You can use a profile like 104 and extend it with the BCL AsyncBridge support classes. For more on this see http://channel9.msdn.com/Events/Build/2012/3-004 and the resources. Several people have done this - but I don't

It works fine on my Ubuntu 12.04 32-bit machine, but I'm having problems getting things to work on a Fedora 17 64-bit machine. Everything compiles fine, but when I try to run it I get: Exception in thread "main" java.lang.UnsatisfiedLinkError: /pathto/libmylib.so: dlopen: cannot load any more object with static TLS Any help is greatly appreciated! UPDATE: I've narrowed this down to a problem with PCL (point cloud library) dependencies. libmylib.so depends on
