Description

read_poseread_poseReadPoseReadPoseReadPoseread_pose is used to read the 3D pose PosePosePosePoseposepose from a text file with the name PoseFilePoseFilePoseFilePoseFileposeFilepose_file. 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_poseCreatePoseCreatePoseCreatePosecreate_pose).

A suitable file can be generated by the operator write_posewrite_poseWritePoseWritePoseWritePosewrite_pose 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
