Abstract: The invention relates to a method (100) for detecting a moving body close to a structure, which comprises: a step (105) of capturing a video stream; a step (110) of decomposing the video stream into a sequence of images; a step (125) of subtracting a first image and a second image from the sequence; a step (150) of detecting a movement which is representative of the presence of a moving body; a step (155) of defining coordinates which are representative of a search window of the moving body; a step (170) of constituting a sequence of truncated images by selecting, in the initial sequence of images, an area of the images which are restricted to the search window; and a step (175) of processing, by means of a trained neural network, the sequence of truncated images.

Abstract: Disclosed is a method for monitoring an installation having a first level of dangerousness for an animal species in a first operating state (E1), the method including a step (107) in which the installation is switched to a second operating state (E2) in which the installation has a second lower level of dangerousness. The installation is switched to the second operating state on the basis of at least one criterion linked to the activity of the animal species or on the basis of a multivariate model for predicting the activity. Also disclosed is a computer program including instructions for implementing the method, to a device for implementing same, and to a system including such a device.
