Estimation of electromechanical quantity by digital image and model-based filtering technique

摘要

A method for estimating at least one of the following amounts from an electromechanical device and / or a component, the method comprising: generating a photorealistic numerical model of an electromechanical device or a portion thereof, A measurement step for combining the output of the physical sensor, which is an imaging device for visualizing the outer surface of the physical electromechanical device in the image, an estimation step of combining the photorealistic numerical model and the measurement step to provide an estimate of the desired electromechanical amount , Said estimating step comprising at least the estimating step based on at least the use of a similarity metric between an (at least one) two-dimensional image of the electric machine or part thereof and an image generated by a photorealistic numerical model do.
