REGISTRATION OF TRAFFIC SIGNS' FEATURE VECTORS IN REMOTE SERVER

In an embodiment, a navigation system for a host vehicle may include at least one processor comprising circuitry and a memory. The memory may include instructions that when executed by the circuitry cause the at least one processor to receive at least one image from a camera on a host vehicle, to analyze the at least one image to identify at least one object represented in the image, to generate a feature vector representative of the at least one object, to compare the generated feature vector to a plurality of feature vectors stored in a database and in response to a determination that the generated feature vector does not match an entry in the database, send the generated feature vector to a server, wherein the server is configured to generate an updated feature vector database in response to the generated feature vector sent by the host vehicle navigation system in combination with feature vectors received from a plurality of additional vehicles.
