Problems solved by technology
[0003] Existing rescue methods are generally searched by manpower, the search range is limited, the search and rescue efficiency is low, and it is greatly affected by the terrain
Air search is more efficient, but at present China's general aviation is not popularized and lacks the necessary professional air search equipment, still can only rely on pilots and crews to conduct naked eye search, the efficiency is low

Embodiment
[0121] Read the video of the search and rescue area through the image reading and analysis module; decompose the video, parse the video into a frame-by-frame image, and then send it to the image processing module; the image processing module processes the image into a two-dimensional array of RGB matrix , and then sent to the image color binarization processing module;
[0122] Input the known parameters through the parameter setting module; the known parameters include: the width of the field of view corresponding to the picture is 2 kilometers, the width of the picture is 2 thousand pixels, the size of the target object is 2 meters, and the color of the target object is red; The theoretical calculation value of the pixel occupied by the target object is calculated as 2 pixel values by known parameters; if the lens distortion magnification factor is 1.5, the pixel value occupied by the target object in the picture is 3;
[0123] Process the picture into a color binarization...

The invention discloses a method for searching for mountain climbers in distress by using computer vision, which includes the following steps: first, read the video or picture of the search and rescue area; The color range of the object; the third step is to determine the convolution kernel matrix; process all the pixels of the picture in the search and rescue area into an RGB matrix of a two-dimensional array, and then perform binary processing on the colors of all the pixels of the picture to obtain the color Binarization matrix; the fourth step is to perform a convolution operation on the convolution kernel matrix and the color binarization matrix to obtain a convolution processing matrix. The invention uses computer vision to analyze and process the distant view photos or videos of the search area on the basis of the search and rescue personnel taking photos or pictures of the search area from a distance or from an aircraft, and identifies and marks the positions of possible missing persons therein. The invention also discloses a system for searching mountaineering persons in distress by using computer vision.
Description
technical field [0001] The invention relates to an application method of computer vision, in particular to a method for searching for mountain climbers in distress by using computer vision. The invention also relates to a system for searching for persons in distress while climbing a mountain by using computer vision. Background technique [0002] With the development of the economy and the popularity of sports tourism, more and more people like outdoor sports such as mountaineering and hiking. However, due to the natural high risk of outdoor sports, several casualties caused by outdoor sports will occur every year, among which the more serious ones are fatal accidents after missing persons. Therefore, once a missing person accident occurs during outdoor sports, various professional rescue teams and civil rescue teams will actively participate in the search and rescue. [0003] Existing rescue methods generally use manpower to search, the search range is limited, the search...
