get_descriptor_model_points( : : ModelID, Set, Subset : Row, Column)

描述

With the operator get_descriptor_model_pointsget_descriptor_model_pointsGetDescriptorModelPointsGetDescriptorModelPointsGetDescriptorModelPointsget_descriptor_model_points interest points of the descriptor model or the last processed search image can be queried. It requires a ModelIDModelIDModelIDModelIDmodelIDmodel_id returned by create_uncalib_descriptor_modelcreate_uncalib_descriptor_modelCreateUncalibDescriptorModelCreateUncalibDescriptorModelCreateUncalibDescriptorModelcreate_uncalib_descriptor_model, create_calib_descriptor_modelcreate_calib_descriptor_modelCreateCalibDescriptorModelCreateCalibDescriptorModelCreateCalibDescriptorModelcreate_calib_descriptor_model, or read_descriptor_modelread_descriptor_modelReadDescriptorModelReadDescriptorModelReadDescriptorModelread_descriptor_model。

The interest points stored in the model can always be queried by setting SetSetSetSetsetset to 'model'"model""model""model""model""model" and SubsetSubsetSubsetSubsetsubsetsubset to 'all'"all""all""all""all""all". If a find_uncalib_descriptor_modelfind_uncalib_descriptor_modelFindUncalibDescriptorModelFindUncalibDescriptorModelFindUncalibDescriptorModelfind_uncalib_descriptor_model or find_calib_descriptor_modelfind_calib_descriptor_modelFindCalibDescriptorModelFindCalibDescriptorModelFindCalibDescriptorModelfind_calib_descriptor_model precedes, with get_descriptor_model_pointsget_descriptor_model_pointsGetDescriptorModelPointsGetDescriptorModelPointsGetDescriptorModelPointsget_descriptor_model_points the interest points of the last search image can be queried as well by setting SetSetSetSetsetset to 'search'"search""search""search""search""search" and SubsetSubsetSubsetSubsetsubsetsubset to 'all'"all""all""all""all""all". Additionally, the matched (corresponding) points for each object instance found can be queried by setting SetSetSetSetsetset to 'model'"model""model""model""model""model" or 'search'"search""search""search""search""search" (for the correspondences on the model or search image side, respectively) and SubsetSubsetSubsetSubsetsubsetsubset to the result number of the instance. The image coordinates of the queried points are returned in RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn。
