Method of synthetic representation of elements of interest in a viewing system for aircraft

A method of synthetic representation of elements of interest in a viewing system for aircraft, the said viewing system comprising at least sensors of location of the said aircraft, a first cartographic database, a second database of elements of interest, an image sensor, a processing unit for the images arising from the said image sensor, a unit for generating three-dimensional digital images representative of the terrain overflown by the aircraft as a function of the data arising from the location sensors, from the cartographic database and the database of elements of interest and from the image processing unit and a viewing device, wherein

• when the terrain overflown comprises at least one element of interest present in the database of elements of interest, the said element being displayed in the three-dimensional digital images representative of the terrain overflown, the said method of synthetic representation comprises at least:
• a first step of searching for and detecting the said element of interest in each image of a sequence of images arising from the image sensor, the detection being ensured by the processing unit and;
• a second step of generating three-dimensional digital images representative of the terrain overflown, the element of interest being represented according to a first representation if it has not been detected in any of the images of the sequence of images arising from the image sensor and according to a second representation if it is detected in at least one image of the sequence of images.
