Following is the claim for this invention:-

1. In this invention we control the take off and landing of drones by programming its firmware with a list of images which is used by the drone to check whether a given area( whose image is captured and provided to the drone through an external device or a remote server along with metadata of the image like its geofence, etc.) is eligible for it's take off or landing purposes. The drone checks for the eligibility of an area whose image is provided, by comparing if the provided image is similar to any of the enlisted images in it's firmware by using algorithms like Hausdorff-Based Matching, Wavelet Transform, etc. If the area is eligible then the drone before take off or landing, returns a successful response to the external device or the remote server which sent the image of the area. The above novel technique by which we control take off and landing of drones is the claim for this invention.
