Abstract:
1. A method for detecting an object in a scene situated in a determined angular sector, and capable of comprising one or more artifacts, comprises a step of scanning the sector the angular width A of which is scanned at an angular velocity θ′, a step of acquiring digital images of the scene at a rate f by means of a matrix detector, these images comprising pixels and covering an instantaneous field of angular width “a”, and further comprising the following steps of processing the acquired images, in batches of N consecutive images where N=af/θ′: dividing the N images into P groups of images, P being an integer greater than 1, for each group p, p being between 1 and P, accumulating the images of the group so as to obtain an accumulated image I for each image I for each image I
