描述

reduce_object_model_3d_by_viewreduce_object_model_3d_by_viewReduceObjectModel3dByViewReduceObjectModel3dByViewReduceObjectModel3dByViewreduce_object_model_3d_by_view projects the points of ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3Dobject_model_3d into the image plane given by PosePosePosePoseposepose and CamParamCamParamCamParamCamParamcamParamcam_param and reduces the 3D object model to the points lying inside the region given in 区域区域区域区域区域区域. In particular, the points are first transformed with the pose and then projected using the camera parameters. Only those points that are located inside the specified region are copied to the new 3D object model.

Faces of a mesh are only contained in the output 3D object model if all corner points are within the region.

As alternative to camera parameters and a pose, an XYZ-mapping contained in ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3Dobject_model_3d can be used for the reduction. For this, CamParamCamParamCamParamCamParamcamParamcam_param must be set to 'xyz_mapping'"xyz_mapping""xyz_mapping""xyz_mapping""xyz_mapping""xyz_mapping" or an empty tuple and an empty tuple must be passed to PosePosePosePoseposepose. In this case, the original image coordinates of the 3D points are used to check if a point is inside 区域区域区域区域区域区域.

注意

Cameras with hypercentric lenses are not supported.
