A method for obtaining cut elongated glass elements includes: providing a continuous elongated glass element; continuously measuring one or more geometric parameters of the continuous elongated glass element to obtain one or more continuous geometric parameters; cutting the continuous elongated glass element to obtain cut elongated glass elements; measuring one or more geometric parameters at one or more points along a rotation axis of one or more of the cut elongated glass elements to obtain one or more individual geometric parameters; and connecting the one or more of the continuous geometric parameters with the one or more of the individual geometric parameters.
