Automatic top-view transformation for vehicle backup rear-view camera

An automatic top-view transformation method is presented for a vehicle backup rear-view camera. The proposed method consists of two steps: i) automatic corresponding points estimation based on the lens specification and ii) view transformation based on the direct linear transform algorithm. Major contribution of this work is automatic view transformation that is optimized for the vehicle rear view camera system. The proposed method can be applied to various imaging systems, such as automotive imaging systems, intelligent surveillance systems, and vehicle rear view cameras.
