Hi Metal!

The error message

`const struct sensor_msgs::PointCloud2_<std::allocator<void> >’ has no member named ‘points’

The variable input has type sensor_msgs::PointCloud2, you can see its definition here.

You can use input->data or transform input to a pcl::PointCloud<pcl::pointxyz> which is somewhat easier to use.

You can do it like this

pcl::PointCloud<pcl::PointXYZ> input_;
pcl::fromROSMsg(*input, input_);

I hope this is helpful for you. Martin.
