read_poseT_read_poseReadPoseReadPose (Operator)

Name

read_poseT_read_poseReadPoseReadPose — Read a 3D pose from a text file.

Signature

read_pose( : : PoseFile : Pose)

Herror T_read_pose(const Htuple PoseFile, Htuple* Pose)

void ReadPose(const HTuple& PoseFile, HTuple* Pose)

void HPose::ReadPose(const HString& PoseFile)

void HPose::ReadPose(const char* PoseFile)

static void HOperatorSet.ReadPose(HTuple poseFile, out HTuple pose)

void HPose.ReadPose(string poseFile)

Description

read_poseread_poseReadPoseReadPoseReadPose is used to read the 3D pose PosePosePosePosepose from a text file with the name PoseFilePoseFilePoseFilePoseFileposeFile. The default HALCON file extension for the 3D pose is 'dat'.

A pose describes a rigid 3D transformation, i.e., a transformation consisting of an arbitrary translation and rotation, with 6 parameters, three for the translation, three for the rotation. With a seventh parameter different pose types can be indicated (see create_posecreate_poseCreatePoseCreatePoseCreatePose).

A suitable file can be generated by the operator write_posewrite_poseWritePoseWritePoseWritePose and looks like the following:

  # 3D POSE PARAMETERS: rotation and translation

  # Used representation type:
  f 0

  # Rotation angles [deg] or Rodriguez-vector:
  r -17.8134 1.83816 0.288092

  # Translational vector (x y z [m]):
  t 0.280164 0.150644 1.7554
