Abstract:
1. A method of measuring dynamic parameters of an aircraft progressing over an airport zone including a runway, said method comprising: calculating the polar coordinates (r,θ) of a first straight line supporting a direction of center line, in an acquired image, wherein the calculation of the polar coordinates (r,θ) of the first straight line comprises the following steps: calculating an angular deviation XTK between said first straight line and a second straight line supporting the direction of a current trajectory of the aircraft and calculating a lateral deviation XTE between the first straight line and the second straight line, wherein the step of detecting the straight lines comprises the following steps: estimating a number of straight lines (n) to be detected in the black and white binary image (I determining the straight lines exhibiting the largest probability of occurrence in the black and white binary image (I
