Method for Detecting a Production Error of an Assembly in a Manufacturing Facility

Abstract

A method for detecting a production error of an assembly in a manufacturing facility includes (i) providing sensor data having at least two dimensions, wherein a respective dimension of the sensor data comprises measurement data with respect to the assembly, (ii) performing a dimensional reduction of the sensor data, wherein at least one feature is extracted based on the at least two dimensions of the sensor data, (iii) reconstructing the dimension-reduced sensor data based on the at least one extracted feature to provide reconstructed sensor data, (iv) determining a reconstruction error based on a comparison of the sensor data with the reconstructed sensor data, and (v) detecting the production error of the assembly based on the determined reconstruction error. Also disclosed is a computer program, a device, and a storage medium for this purpose.
