A computer-implemented method for predicting the
operating time until a failure state of a
system (140), wherein the computer-implemented method comprises: Receiving a plurality of historical image pairs of a
system (140), such as image pairs of a failure state of the
system (140), by one or more processors (304), wherein each
image pair contains an
infrared image and a corresponding normal image; Receiving an initial model by the one or more processors (304), which is trained to reconstruct each
image pair of the system (140) in a functioning state (120) of the system (140);Generating a similarity coefficient between each historical
image pair and a reconstruction of the historical image pair by the first model for the plurality of historical image pairs by the one or more processors (304), wherein the historical image pair contains a
timestamp of a capture of the historical image pair; Receiving a second model by the one or more processors (304), which is trained to predict, based on the similarity coefficients and a
timestamp of a capture of the plurality of historical image pairs, an
operating time until a failure condition of the system (140) occurs;In response to receiving a real-time image pair of the system (140), the one or more processors (304) generate real-time similarity coefficients between the real-time image pair and the real-time image pair reconstructed by the first model, wherein the real-time image pair contains a
timestamp of the acquisition of the real-time image pair; and the one or more processors (304) calculate a predicted
operating time until the failure state of the system (140) based on a correlation between the similarity coefficients of the real-time image pair and the timestamp of the acquisition of the real-time image pair and a historical image pair from the plurality of historical image pairs with corresponding similarity coefficients and a time
delta determined from the timestamp of the acquisition of the real-time image pair and a timestamp of the failure state of the system (140) after the historical image pair with the corresponding similarity coefficients.
