Description

The operator create_stereo_modelcreate_stereo_modelCreateStereoModelCreateStereoModelCreateStereoModel creates a HALCON stereo model and returns a handle to it in StereoModelIDStereoModelIDStereoModelIDStereoModelIDstereoModelID. The model provides functionality for reconstructing either 3D points or surfaces from a calibrated multi-view stereo camera setup specified in CameraSetupModelIDCameraSetupModelIDCameraSetupModelIDCameraSetupModelIDcameraSetupModelID (refer to calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCameras for further details on calibration of multiple cameras).

For MethodMethodMethodMethodmethod='points_3d'"points_3d""points_3d""points_3d""points_3d", a stereo model is created that, after being configured, can be passed to reconstruct_points_stereoreconstruct_points_stereoReconstructPointsStereoReconstructPointsStereoReconstructPointsStereo. The latter reconstructs 3D points by intersecting lines of sight from point correspondences, extracted from multiple calibrated images (see reconstruct_points_stereoreconstruct_points_stereoReconstructPointsStereoReconstructPointsStereoReconstructPointsStereo for more details).

For MethodMethodMethodMethodmethod='surface_pairwise'"surface_pairwise""surface_pairwise""surface_pairwise""surface_pairwise" or MethodMethodMethodMethodmethod='surface_fusion'"surface_fusion""surface_fusion""surface_fusion""surface_fusion", a stereo model is created that, after being configured, can be passed to reconstruct_surface_stereoreconstruct_surface_stereoReconstructSurfaceStereoReconstructSurfaceStereoReconstructSurfaceStereo. The latter obtains disparity images from preselected image pairs in a calibrated multi-view stereo setup and fuses the collected 3D information in a single surface reconstruction (see reconstruct_surface_stereoreconstruct_surface_stereoReconstructSurfaceStereoReconstructSurfaceStereoReconstructSurfaceStereo for more details).

The parameters GenParamNameGenParamNameGenParamNameGenParamNamegenParamName and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue can be used to set general model parameters. Alternatively, these parameters can be modified with the operator set_stereo_model_paramset_stereo_model_paramSetStereoModelParamSetStereoModelParamSetStereoModelParam before the corresponding reconstruction operator is called (see set_stereo_model_paramset_stereo_model_paramSetStereoModelParamSetStereoModelParamSetStereoModelParam for more details on the available model parameters).

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
