Abstract

A method for detecting moving objects in a blind spot of vehicle is provided, comprising: taking a sequence of images of said blind spot region, partitioning each of said images of said sequence into blocks, identifying moving blocks which have moved between consecutive images of said sequence, determining a direction and a distance of said movement of said moving blocks; grouping adjacent moving blocks, for which directions within a predetermined direction interval and distances within a predetermined distance interval have been determined, and determining said moving objects based on said step of grouping. A corresponding blind spot detection device is provided as well.
