摘要
Asynchronous information is provided by a sensor having a matrix of pixels disposed opposite the scene. The asynchronous information includes, for each pixel of the matrix, successive events originating from this pixel, that may depend on variations of light in the scene. A model representing the tracked shape of an object is updated after detecting events attributed to this object in the asynchronous information. Following detection, the updating of the model includes an association of a point of the model with the event detected by minimizing a criterion of distance with respect to the pixel of the matrix from which the detected event originates. The updated model is then determined as a function of the pixel of the matrix from which the detected event originates and attributed to the object and of the associated point in the model, independently of the associations performed before the detection of this event.
