METHOD FOR DETERMINING PRECIPITATION INTENSITY IN REAL TIME IN AIRCRAFT SYSTEMS OF IMPROVED VISION Russian patent published in 2017 - IPC G01W1/14 G06T7/00 

FIELD: physics.

SUBSTANCE: video is obtained by the television camera of the visible spectral range. Digital video processing is carried out. Analyzing the data resulted after video processing, the presence of precipitation is detected. And at the stage of digital processing, one video frame is processed with the help of the on-board digital computer, while carrying out the following operations: searching vectors of the image function gradient at each point of the image; constructing an oriented histogram of the two-dimensional image function gradient; defining priority vector directions of the image function gradient; searching boundaries corresponding to the priority vector directions of the image function gradient; folding the image with the two-dimensional Haar wavelet for detecting lines; determining the precipitation intensity.

EFFECT: increasing the operating speed and decreasing the required amount of RAM for processing and analyzing the video stream, reducing weight and size characteristics of the on-board equipment.
