Claim One:
1. A device for measuring dynamic parameters of an aircraft progressing over an airport zone, the aircraft being in a phase of rolling along a traffic lane, the traffic lane comprising ground markings and notably a center line, the device comprises: at least one means for acquiring images, means for measuring the deviation of the aircraft with respect to the center line on the basis of acquired images, said means for measuring the deviation of the aircraft with respect to ground markings on the basis of said acquired images comprising: means for calculating the coordinates of a first straight line supporting the direction of the center line, and means for calculating an angular deviation XTK between said first straight line and a second straight line supporting the direction of the current trajectory of the aircraft and for calculating a lateral deviation XTE between the first and the second straight line. means for measuring speed and position of said aircraft on the basis of said acquired images, said speed and position measuring means comprising: means for recognizing ground marking elements on the basis of the acquired images, means for correlating the recognized ground marking elements with referenced elements in an airport database, means for consolidating the speed and position calculated with speed and position estimated by other measuring equipment.
