1. A method of a digital processor for Time Of Flight sensor 2-dimensional and 3-dimensional map generation, comprising: retrieving Time Of Flight sensor fixed point data to obtain four phases of Time Of Flight fixed point raw data; computing Gray scale image array and phase differential signal arrays utilizing four phases of TOF fixed point raw data; computing Gray image array and Amplitude image array for fixed point; converting the phase differential signal array from fixed point to floating point; performing the floating point division for computing Arctan, TOF depthmap, and 3-dimensional point cloud map for Q format fixed point; and generating depthmap, 3-dimensional cloud coefficients and 3-dimensional point cloud for Q format fixed point.
