Detailed Description

template<typename PointT>
class pcl::FrustumCulling< PointT >

FrustumCulling filters points inside a frustum given by pose and field of view of the camera.

Code example:

pcl::PointCloud <pcl::PointXYZ>::Ptr source; 
// .. read or fill the source cloud
 
pcl::FrustumCulling<pcl::PointXYZ> fc;
fc.setInputCloud (source);
fc.setVerticalFOV (45);
fc.setHorizontalFOV (60);
fc.setNearPlaneDistance (5.0);
fc.setFarPlaneDistance (15);
 
Eigen::Matrix4f camera_pose;
// .. read or input the camera pose from a registration algorithm.
fc.setCameraPose (camera_pose);
 
pcl::PointCloud <pcl::PointXYZ> target;
fc.filter (target);

◆ setCameraPose()

template<typename PointT >

inline

Set the pose of the camera w.r.t the origin.

Parameters

[in] camera_pose the camera pose

Note: This assumes a coordinate system where X is forward, Y is up, and Z is right. To convert from the traditional camera coordinate system (X right, Y down, Z forward), one can use:

Eigen::Matrix4f pose_orig = //pose in camera coordinates
Eigen::Matrix4f cam2robot;
cam2robot << 0, 0, 1, 0
             0,-1, 0, 0
             1, 0, 0, 0
             0, 0, 0, 1;
Eigen::Matrix4f pose_new = pose_orig * cam2robot;
fc.setCameraPose (pose_new);
