Abstract

Provided is a computer implemented method for representing at least part of a real-world environment based on measurements performed by a measurement device. The method comprises transforming a ray from the first coordinate system to a second coordinate system used for representation of said measurements, sampling the transformed ray to be represented by a plurality of synthetic points, determining a discrepancy between the transformed ray and a straight line connecting the synthetic points, if the discrepancy is larger than a specific threshold value, reducing the specific distance between the synthetic points, and/or adding a new synthetic point between the synthetic points, performing a polynomial regression based on at least a subset of the synthetic points to determine a polynomial function representing the synthetic points, and thereby providing a correlation between the first coordinate system and the second coordinate system. An apparatus on which the method is implemented is also provided.
