Vehicle with improved traffic-object position detection using symmetric search

摘要

A method for detecting the position of a target object in the environment of a host vehicle. The method may include receiving a first position of the target object as detected by an object position sensor which emits waves and receives the waves that are reflected back by the target object, and receiving an image containing the target object as detected by an image sensor. The method may also include projecting the first position on the image, and refining the first position by computing a second refined position of the target object on the basis of a symmetry search within the image.

1. A method for detecting the position of a target object in the environment of a host vehicle, comprising the following steps:
receiving a first position information on the target object using an object position sensor which emits waves and receives the waves that are reflected back by the target object, receiving an image containing the target object as detected by an image sensor, projecting the first position on the image, and refining the first position by computing a second refined position of the target object on the basis of a symmetry search within the image, wherein the symmetry search is performed within a horizontal symmetry search area, the symmetry search area being located in the image in accordance with the first position, centered on the first position and being defined based on a precision limit of the object position sensor.
