1. A method, comprising:

  • generating a pattern of symbols to project as a projected image, said pattern including an array of symbols having a number of symbol columns and a number of symbol rows;

    obtaining an image from a camera;

    decoding said obtained image, generating a decoded pattern of symbols comprising an array having said number of symbol columns and number of symbol rows, the decoding including;

    defining an array of classification windows of said obtained image, wherein said array of classification windows has said number of symbol columns and number of symbol rows;

    determining a displacement of each classification window by optimizing a cost function; and

    generating said decoded pattern by determining a respective symbol for each classification window; and

    generating a depth map as a function of said pattern of symbols to project and said decoded pattern, wherein said determining a respective symbol for each classification window comprises classifying the symbol in each classification window using an artificial neural network.
