Abstract
Methods, systems, and computer-readable and executable instructions are described herein. One method includes receiving a sequence of images of a flare stack area from a thermal imaging component, identifying a first portion of the flare stack area moving at a first threshold optical flow using the sequence of images of the flare stack area, and identifying a second portion of the flare stack area moving at a second threshold optical flow using the sequence of images of the flare stack area.
Claims20
A method for flare monitoring, comprising:
- receiving a sequence of images of a flare stack area from a thermal imaging component;
- identifying a first portion of the flare stack area moving at a first threshold optical flow using the sequence of images of the flare stack area;
- and identifying a second portion of the flare stack area moving at a second threshold optical flow using the sequence of images of the flare stack area.
A non-transitory computer-readable medium storing instructions executable by a processing resource to:
- receive a sequence of images of a flare stack area captured by a thermal imaging component;
- receive an identification of a smoke portion and a flare portion of the sequence of images of the flare stack area;
- identify a first threshold optical flow of smoke movement using the received sequence of images and the received identification of the smoke portion of the images of the flare stack area;
- and
- identify a second threshold optical flow of flare movement using the received sequence of images and the received identification of the flare portion of the images of the flare stack area.
A flare assembly monitoring system, comprising
- a thermal imaging component operated to capture a sequence of thermal images of a flare stack area over a period of time;
- an optical imaging component operated to capture a sequence of optical images of the flare stack area over the period of time;
- and
- a computing component operated to:
- receive the sequence of thermal images and the sequence of optical images;
- and
- process each of the images in the sequences, wherein processing an image includes:
- separate a foreground of the image from a background of the image using a temperature-intensity map;
- identify a smoke portion of the foreground of the image based on the smoke portion moving at a first threshold optical flow between the sequences of images;
- identify a flare portion of the foreground of the image based on the flare portion moving at a second threshold optical flow between the sequences of images;
- and
- segment the identified smoke portion and the identified flare portion of the image.
