Abstract:
The present invention discloses a landing protection method and apparatus and an aircraft. The method includes: obtaining an image of a landing area; determining a feature point in the image; determining, according to the feature point, whether the landing area is a dangerous landing area; and if yes, controlling the aircraft to suspend landing or controlling the aircraft to fly away from the dangerous landing area. By means of the present invention, whether a landing area is a dangerous landing area may be determined according to an obtained image, so that the landing safety of the aircraft is ensured.

Claim (Index 11):
The method according to  claim 10 , wherein the determining the proportion Rd of the feature point whose movement distance is greater than a fifth preset threshold in two adjacent frames of images comprises:\n determining a same feature point in the two adjacent frames of images; determining displacement coordinate xd, yd of each same feature point in the two adjacent frames of images; if xd or yd is greater than or equal to the fifth preset threshold, determining that the feature point is the feature point whose movement distance is greater than the fifth preset threshold; and calculating the proportion Rd of the feature point whose movement distance is greater than the fifth preset threshold to all the same feature points in the two sequential frames of images.
