Detection of empty grate regions in firing processes using infrared cameras
نویسندگان
چکیده
Recently, infrared cameras are used in grate firing processes for waste and biomass incineration in order to optimize the process control. These infrared (IR) cameras with a bandpass filter at 3.8 to 4.0 μm allow for a detailed measurement of the solid bed's temperature distribution. Additionally, the current load condition of the grate is of interest for the process control, which cannot be measured so far. In this paper a new image processing algorithm is presented, which extracts detailed information about the load condition for each grate zone from the IR-images. The new algorithm is based on a correlation method using prior domain knowledge (template) in order to increase the reliability of the calculated parameters.

In the search and rescue efforts soon after disaster such as floods, the time critical activities of survivor detection and localization can be solved by using thermal long-wave infrared (LWIR) cameras which are more robust to illumination and background textures than visual cameras. This particular problem is especially challenging due to the limited computational power available on-board comm...
