If you use Poisson reconstruction:

1) Point Weight parameter controls how much the interpolation is constrained

to be close to the original points. Default values is 4. You need to

increase it.

void setPointWeight (float point_weight)

http://docs.pointclouds.org/trunk/classpcl_1_1_poisson.html#a9152fd1faeadc56bf654f6def2ebdcee2) Confidence parameter should be set to True, so that the magnitude of the

normals will be used as the weight for each point. Which also means you need

to update the magnitude of normals in your point cloud accordingly.

void setConfidence (bool confidence)
