DEVICE AND METHOD FOR CORRECTING DIRECTIONAL DRIFTS IN TOPOGRAPHIC IMAGE DATA

摘要

The invention relates to a device (100) for correcting directional drifts in topographic image data, comprising a receiver (103) configured to receive the topographic image data in a raw data format, wherein the topographic image data comprises values representing spatial coordinates of a topography, and wherein the values are in a first range, a processor (105) configured to normalize said values of the topographic image data to a second range, and a trainable neural network (107) configured to receive the topographic image data with normalized values and to remove a directional drift of the normalized values, wherein, following removal of the directional drift by the neural network (107), the processor (105) is configured to denormalize the values, in particular to the first range, to generate corrected topographic image data.
