Claim 0:
1. Method for enhancing images for metrological applications comprising:
acquiring a sensor image
representing a scene of interest with initial metrological information for determining position or orientation of at least one object within the scene of interest,
having a sensor image geometric correctness, wherein the geometric correctness corresponds to a measure of deviations of edges and
being described by an image parameter provided by a scoring function evaluated on the sensor image, the image parameter in particular relating to brightness or noise or resolution or color fidelity or vividness of colors of the sensor image, the image parameter having an initial image parameter value,

generating an enhanced image from the sensor image
being described by the image parameter having an enhanced image parameter value, the enhanced image parameter value in particular relating to higher brightness or reduced noise or higher resolution or higher color fidelity or more vivid colors than the sensor image, and
having a processed image geometric correctness, the processed image geometric correctness relating to distorted metrological information representing a loss of initial metrological information caused by an image processing with a neural network, the processed image geometric correctness being lower than the sensor image geometric correctness,

acquiring a geometric correction image
having an image geometric correctness higher than the processed image geometric correctness,
showing at least a part of the scene of interest,

at least partially reducing the loss of initial metrological information in the distorted metrological information by fusing the enhanced image with the geometric correction image.
