PointCloud Ground truth is too sparse #146

Open fabfabBesnard opened 2 years ago

fabfabBesnard commented 2 years ago

When working with virtual plant The ground truth point cloud available for comparison is too sparse: only a few points are displayed. The resolution should be increased

I recommend removing completely any down-sampling from plantdb and plant-3d-vision, as file size is not a problem.

Using large point clouds may become a problem in the explorer, but then a RandomSampling strategy may be implemented. For example, this one (https://github.com/PointCloudLibrary/pcl/blob/master/filters/src/random_sample.cpp) ll 122-147 that I've used successfully in other applications.

As the number of points is really a visual thing I believe the explorer should take care of it. It would also be more maintainable.

It would also be then possible to have the point cloud size as a parameter (a slider for example).
