Abstract
A method for refocusing, on at least one common point of interest, the rendering of one set of plenoptic video data provided by one plenoptic device belonging to a set of plenoptic devices capturing simultaneously a same scene. According to the present disclosure, said method comprises: obtaining (21) a common 3D reference system used for spatially locating said plenoptic device that has provided said set of plenoptic video data and at least one other device of said set of plenoptic devices, from said at least one common point of interest, determining (22) common refocusing plane parameters in said common 3D reference system, refocusing (23) the rendering of said set of plenoptic video data by converting (231) said common refocusing plane parameters into a rendering refocusing plane of a 3D reference system associated with said plenoptic device.
