1. A lost article management method in a vehicle, comprising:
generating first detection information by detecting a passenger or an article by using a first camera or first sensor that is installed in the vehicle to be separated by a first distance from a seated point of the passenger;
generating second detection information by detecting the passenger or the article by using a second camera or second sensor that is installed in the vehicle to be separated by a second distance from the seated point, wherein the second distance is longer than the first distance;
generating third detection information by detecting a background excluding the passenger and the article;
providing a lost status prediction model generated through learning;
determining whether an article has been lost from the first detection information to the third detection information by using the lost status prediction model; and
providing a lost article confirmation request to the passenger when it is determined that the article has been lost;
wherein the generating of the third detection information includes classifying the background into an area in which the passenger is able to put the article down and a prohibited area in which the passenger is not able to put the article down.
