Title:
METHOD FOR IMAGE PROCESSING AND METHOD FOR TRACKING THE COURSE FOLLOWED BY LAUNCHED ROCKETS
Document Type and Number:
WIPO Patent Application WO/2014/056473
Kind Code:
A3
Abstract:
Method for image processing for improving the signal-to-noise ratio in the image information, wherein the processing is performed in the following sub-steps: b2) overlaying a raster image element with a central raster filter element (22) of a raster filter (22) comprising an odd number of lines and an odd number of columns; b3) determining the brightness values of each of the raster image elements covered by the raster filter (22), wherein apart from the central raster filter element (22) every other raster filter element (22) has an individual light attenuation characteristic; b4) summing the brightness values determined in step b3) to form a total brightness value and assigning this total brightness value to the raster image element covered by the central raster filter element (22); b5) repeating steps b2) to b4) for all remaining raster image elements; and method for tracking the course followed by launched rockets, said method having the following characteristics: a. selecting an observation point to the side beneath the target; b. tracking using the temperature image of the core engine jet measured by a narrowband multispectral camera with at least three bands.
