Zusammenfassung:	The invention relates to a method for measuring the sagging of a glass panel while bending the glass panel on a ring mould. Sagging is measured with a matrix camera and the measurement data is coupled to control the progress of a bending process, particularly the heating of glass or the abortion of a bending process. The ring mould can be provided with fixed pointers for facilitating a camera-operated measurement. In addition, at least one point on the glass surface, preferably between the pointers, is made visible to the camera.
