Abstract:
1. A process for detecting an object in relation to a surface, said surface not necessarily being flat, said process comprising: realizing a computer-generated image associated to a viewpoint being considered for each viewpoint by a geometric conversion at least including a projection in perspective of said object on said surface from at least two distinct viewpoints; distinguishing between the computer-generated images for detecting a presence and determining a position of said object in relation to said surface, said distinguishing between the different computer-generated images including: wherein to realize each of said computer-generated images associated to a viewpoint being considered, at least one of radioactive emissions, electromagnetic rays, and mechanical vibrations emitted by said object are captured from each viewpoint to produce a signal, said signal is digitized to obtain digitized data, and said computer-generated images are calculated based on the obtained digitized data, and wherein said computer-generated images show zones in different colors, said process searches for opposing differences on each of the two selected computer-generated images, and inversions of color contrasts between zones situated along each of the specific virtual directions of each field are sought.
