Flaw with compute3DCentroid and getMinMax3D

edit

Hey everyone, I'm using the "standard" way of creating bounding boxes for a point cloud cluster, which most resources online are using. My code posted below. However it seems there is a flaw here, because as seen in the screenshot, the algorithm seems to shift the bounding box a certain amount too far forward. I'm wondering where the offset is coming from?

visualization_msgs::Marker mark_cluster(pcl::PointCloud<pcl::PointXYZ>::Ptr cloud_cluster, int ide)
{
  Eigen::Vector4f centroid;
  Eigen::Vector4f min;
  Eigen::Vector4f max;

  pcl::compute3DCentroid (*cloud_cluster, centroid);
  pcl::getMinMax3D (*cloud_cluster, min, max);

  uint32_t shape = visualization_msgs::Marker::CUBE;
  visualization_msgs::Marker marker;
  marker.header.frame_id = "laser";
  marker.header.stamp = ros::Time::now();

  marker.ns = "objects";
  marker.id = ide;
  marker.type = shape;
  marker.action = visualization_msgs::Marker::ADD;

  marker.pose.position.x = centroid[0];
  marker.pose.position.y = centroid[1];
  marker.pose.position.z = centroid[2];
  marker.pose.orientation.x = 0.0;
  marker.pose.orientation.y = 0.0;
  marker.pose.orientation.z = 0.0;
  marker.pose.orientation.w = 1.0;

  marker.scale.x = (max[0]-min[0]);
  marker.scale.y = (max[1]-min[1]);
  marker.scale.z = (max[2]-min[2]);
   ...
