System for detecting the inclination of light sources, in particular of precision approach slope indicators of an airport runway

Process for detecting the inclination of one or more light beams, having at least one sharp colour transition, emitted by one or more light sources, in particular precision approach slope indicators, comprising the following steps:

• acquiring images of said one or more light beams through optoelectronic means;
• processing said images for checking whether said at least one sharp colour transition appears in at least one corresponding predetermined position thereof;
• in the case where said at least one sharp colour transition does not appear in said at least one corresponding predetermined position, controlling first powered means so as to modify an inclination of the optoelectronic means;
• and
• in the case where said at least one sharp colour transition appears in said at least one corresponding predetermined position, measuring an inclination value of the optoelectronic means.

System for detecting the inclination of one or more light beams, having at least one sharp color transition, emitted by one or more light sources, in particular precision approach slope indicators, comprising;

• an inclination measurer designed to measuring inclination;
• image acquisition optoelectronics designed to acquire images;
• a first inclinator designed to incline the image acquisition optoelectronics;
• wherein the inclination measurer is mechanically coupled to image acquisition optoelectronics so as to measure the inclination of the image acquisition optoelectronics;
• an electronic processing unit that controls the first inclinator on the basis of the images acquired by the image acquisition optoelectronics so that, when the system carries out a detection of the inclination of said one or more light beams, said at least one sharp color transition appears in at least one corresponding predetermined position of said acquired images, said electronic processing unit reading an inclination value outputted by the inclination measuring means for displaying the same on a display.
