The disclosure relates to imaging to determine electrode geometry. A method includes placing a set of electrodes on a body surface of a patient's body. The method further includes digitizing a position of an electrode across the body surface based on one or more image frames using ranging imaging and/or monoscopic imaging. The method further includes estimating a position of a hidden electrode of the electrodes on the body surface that is not visible during ranging imaging and/or monoscopic imaging. The method further includes registering the position of the electrode on the body surface with predetermined geometry information, the predetermined geometry information including the body surface and an anatomical envelope inside the patient's body. The method further includes storing geometry data based on the registration for defining a spatial relationship between the electrode and the anatomical envelope in a non-transitory memory. 本公开涉及成像以确定电极几何形状。一种方法包括在患者身体的身体表面上放置电极组。该方法还包括基于使用测距成像和/或单视成像的一个或多个图像帧将跨越身体表面的
