A METHOD AND DEVICE FOR IDENTIFYING MATERIAL TYPES OF SPATIAL OBJECTS

摘要

The present invention relates to a method for identifying material types of spatial objects characterized in that the method comprising obtaining an acoustic signal from each identified object by deforming the objects mechanically, recording said acoustic signal and comparing it to an acoustic model being obtained on the basis of analysis of reference objects of multiple material types. The present invention also relates to a device for identifying material types of spatial objects, comprising a deformation chamber (K), a mechanical deformation system (F), at least one electro-acoustic transducer (1), an acoustic signal recording assembly (2) and a data processing unit (3) with installed acoustic model being obtained on the basis of analysis of reference objects of multiple material types.
