Abstract
The present disclosure concerns a method for calibrating a plenoptic camera. The plenoptic camera includes a lenslet array placed between a main lens and a photosensor, the lenslet array having a plurality of lenslets. The method is remarkable in that it includes obtaining a white image W and a model that describes light scene occlusion induced by the main lens and each lenslet. For a given pixel of the photosensor, where the model is represented by a set of parameters, obtaining a first subset of parameters values from the set of parameters in the model and obtaining a second subset of parameters value from the set of parameters in the model by performing a maximum likelihood estimation method based on the model, the white image and the first subset of parameters values, and where a union of the first and the second subsets of parameters corresponds to the set of parameters.
