Abstract
The invention relates to a method for detecting an object () in relation to a surface (). A synthetic image () is produced from at least two distinct viewpoints (), for each of said viewpoints, by means of a geometrical transformation comprising at least one perspective projection () of the object on the surface (), each synthetic image being associated with the viewpoint concerned. By discriminating between the synthetic images, it is possible to detect the presence of and determine the position of the object () in relation to the surface (), by searching for contrast inversions. The invention can be used for surveying a swimming pool.
