Abstract

In a sensor system and a corresponding method for image capture of an object, an imaging sensor is arranged in a recording area of an optical sensor, the recording area being defined for the object, in such a way as to be essentially stationary relative to said object. By means of an evaluation unit, relative movements between the imaging sensor and the object can be derived from the recorded image data of the optical sensor, and a three-dimensional object image can be reconstructed from the imaging data as a function of the relative movements. When determining the relative movements, it is in particular possible as well to detect relative movements caused by the object's own motion which can be taken into account when reconstructing the object image. As a result, a high image quality of the object image is achieved.
