METHOD AND APPARATUS FOR ENCODING/DECODING POINT CLOUD GEOMETRIC DATA DETECTED BY AT LEAST ONE SENSOR Russian patent published in 2025 - IPC G06T9/00 G06T3/40 G06F16/901 

FIELD: computer engineering.

SUBSTANCE: method of encoding/decoding point cloud geometric data, represented by ordered coarse points, which occupy part of discrete locations from plurality of discrete locations of two-dimensional space, includes obtaining at least one binary data (f_j), which is a representation of a difference of ordinal indices, representing a difference between ordinal indices of two consecutive occupied coarse points, and encoding each of said at least one binary data (f_j) using the following: obtaining (120) coordinates (s_j,λ_j) of current coarse point (P_j) in two-dimensional space; obtaining (130) amount (N_sens(s_j,λ_j)) measurements based on current coarse point (P_j), wherein said number (N_sens(s_j,λ_j)) measurements is a representation of the average number of successive measurements required by the sensor (λ_j) corresponding to current coarse point (P_j) to detect another coarse point; and entropy encoding (150), into the bit stream, said binary data (f_j) based on the number (N_sens(s_j,λ_j)) of measurements.

EFFECT: high accuracy of determining location.
