Patent ID: 11967091
Assignee: WING AVIATION LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 11:
12. An unmanned aerial vehicle (UAV), comprising:
an image sensor for capturing images of a delivery zone;
data storage including a machine learning model to determine an embedding score; and
a controller coupled to the image sensor, the data storage, and memory, the memory including instructions that when executed by the UAV, cause the UAV to perform operations comprising:
capturing an evaluation image of the delivery zone;
receiving an anchor image of the delivery zone, wherein the anchor image and the evaluation image are representative of the delivery zone at different times;
comparing the anchor image with the evaluation image to determine a degree of similarity between the anchor image and the evaluation image represented by the embedding score associated with the evaluation image, the comparing including:
inputting the anchor image and the evaluation image into the machine learning model to output embedding data from the machine learning model, wherein the embedding data includes embedding values for calculating the embedding score, wherein the embedding score is associated with a distance between representations of the anchor image and the evaluation image within an embedding space, and wherein the distance is proportional to the degree of similarity between the anchor image and the evaluation image; and

determining an occurrence of the environmental change to the delivery zone when the embedding score is outside of a threshold range.
