Abstract (en)

[origin: WO2019057402A1] The invention relates to a method for identifying an object instance of located objects (10) in noisy environments (14) by means of an artificial neural network (CNN), having the steps of: recording a plurality of images (x) of at least one object (10) for the purpose of obtaining a plurality of samples (s) containing image data (x), object identity (c) and orientation (q); generating a training set (Strain) and a template set (Sdb) from the samples; training the artificial neural network (CNN) using the training set (Strain) and a loss function (L), determining the object instance and/or the orientation of the object (10) by evaluating the template set (Sdb) using the artificial neural network. The invention proposes that the loss function used for training has a dynamic margin.
