US 10,885,647 B2 · Estimation of electromechanical quantities by means of digital images and model-based filtering techniques

Abstract

A method for estimating one or more of the following quantities from an electromechanical machine and/or component, the method comprising the creation of a photorealistic numerical model of the electromechanical machine or parts of it, a measurements step for combining outputs of physical sensors of which at least one is an imaging device for visualizing the external surface of the physical electromechanical machine in at least one 2-dimensional image, an estimation step combining the photorealistic numerical model and measurement step to provide an estimate of desired electromechanical quantities, wherein the estimation step is based at least on the usage of a similarity metric between the (at least one) two dimensional image of the electromechanical machine or parts of it and the images generated by the photorealistic numerical model.

A method of sensing a physical object,

the method comprising:
providing a photorealistic virtual object of the physical object;
performing a measurement step, the measurement step comprising recording the physical object and acquiring physical field measurements of the physical object comprising at least one 2 dimensional image;
performing an estimation step, the estimation step comprising applying external excitations to the photorealistic virtual object to create photorealistic virtual field measurements and comparing the photorealistic virtual field measurements with the physical field measurements and therefor sensing the physical object.
