Image matching point pair determination method and device, medium and electronic equipment

The invention provides an image matching point pair determination method, an image matching point pair determination device, a computer readable storage medium and electronic equipment, and relates to the technical field of computers. The method comprises the steps of obtaining a first image and a second image; performing contour detection in the first image to obtain one or more first contours in the first image, performing contour detection in the second image to obtain one or more second contours in the second image, and determining a matching relationship between the first contours and the second contours; determining one or more first key points in the first image, determining one or more second key points in the second image, and determining the distance between the first key points and the second key points; and obtaining a matching point pair of the first image and the second image according to the distance between the first key point and the second key point and a matching relationship between a firs
