Abstract

A system and method is disclosed for acquiring temperature data from a plurality of features in a chamber including capturing a first image of an interior area of the chamber, capturing a second image of the interior area of the chamber, identifying a plurality of features within the data for the first image and the data for the second image, generating an interior area representation based on the first image data, the second image data, and the identification of each feature of the plurality of features in the interior area, and correlating the interior area representation to temperature information related to the interior area.

Claims17

Dependent claims

A method for determining temperature information on a plurality of tubes in a furnace, the method comprising:

capturing a plurality of images of an interior area of a furnace, at least some images of the plurality of images being associated with different portions of the interior area of the furnace, and wherein each image of the plurality of images comprises pixel data associated with a subset of the plurality of tubes positioned inside the furnace;
identifying each tube of the subset of the plurality of tubes in each image of the plurality of images;
processing a portion of the pixel data associated with each identified tube to obtain a value representing a measure of central tendency for each identified tube of the subset of the plurality of tubes in each image of the plurality of images;
and
processing the value representing the measure of central tendency for each identified tube to obtain temperature information for the plurality of tubes.

A method for acquiring temperature data for a plurality of features in a chamber, the method comprising:

capturing a first image of an interior area of the chamber, the first image being associated with a first portion of the interior area, and wherein the first image comprises first image data for the plurality of features positioned within the interior area;
capturing a second image of the interior area of the chamber, the second image being associated with a second portion of the interior area, and wherein the second image comprises second image data for the plurality of features positioned within the interior area;
identifying the plurality of features within the first image data and the second image data;
generating an interior area representation based on the first image data, the second image data, and the identification of each feature of the plurality of features in the interior area, wherein the interior area representation comprises data relating to the plurality of features positioned inside the interior area;
establishing a correlation between the interior area representation and temperature information related to the interior area;
and
calculating temperatures of the plurality of features in the interior area from the interior area representation using the established correlation.
