Method for detecting moving objects in a blind spot region of a vehicle and blind spot detection device
First Claim
1. A method for detecting moving objects in a blind spot region of a vehicle, 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 performed a movement between consecutive images of said sequence;
determining a direction and a distance of said movement of said moving blocks;
splitting said images of said sequence into at least two regions;
segmenting said images by grouping adjacent moving blocks, for which directions within a predetermined direction interval and distances within a predetermined distance interval have been determined, wherein different criteria are used for said segmenting in said at least two regions; and
determining said moving objects based on said step of segmenting.

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.

16. A blind spot detection device for a vehicle, comprising:
-
a camera configured to take a sequence of images of said blind spot region; a splitting region unit configured to split said images of said sequence into at least two regions; a processor configured to partition each of said images of said sequence into blocks, to identify moving blocks which have performed a movement between consecutive images of said sequence, to determine a direction and a distance of said movement of said moving blocks, to segment said images by grouping adjacent moving blocks, for which directions within a predetermined direction interval and distances within a predetermined distance interval have been determined, wherein different criteria are used for said segmenting in said at least two regions, and to determine moving objects; and an indicator configured to indicate a dangerous situation, if a moving object in said blind spot has been detected. - View Dependent Claims (17, 18)
