    • An image processing method is described for determining depth information from at least two input images recorded by a stereo camera system, the depth information being determined from a disparity map taking into account geometric properties of the stereo camera system, characterized by the following method steps for ascertaining the disparity map: transforming the input images into signature images with the aid of a predefined operator, calculating costs based on the signature images with the aid of a parameter-free statistical rank correlation measure for ascertaining a cost range for predefined disparity levels in relation to at least one of the at least two input images, performing a correspondence analysis for each point of the cost range for the predefined disparity levels, the disparity to be determined corresponding to the lowest costs, and ascertaining the disparity map from the previously determined disparities.
    • 描述了一种图像处理方法,用于从由立体相机系统记录的至少两个输入图像中确定深度信息,深度信息是根据立体相机系统的几何属性从视差图确定的,其特征在于以下方法步骤 确定视差图:借助于预定义的操作者将输入图像变换成签名图像,借助于无参数的统计等级相关度量来计算基于签名图像的成本,以确定相关的预定视差水平的成本范围 至少两个输入图像中的至少一个,对于预定视差水平执行成本范围的每个点的对应分析,对应于最低成本确定的差异,以及根据先前确定的差异来确定视差图 。
