Abstract: The present description concerns a system for determining a depth image of a scene, configured to project a spot pattern onto the scene and acquire an image of the scene; determining I and Q values of the image pixels; determining, for each pixel, at least one confidence value to form a confidence image; determining the local maximum points of the confidence image having a confidence value greater than a first threshold; selecting, for each local maximum point, pixels around the local maximum point having a confidence value greater than a second threshold; determining a value Imoy equal to the average of the I values of the selected pixels and a value Qmoy equal to the average of the Q values of the selected pixels; and determining the depth of the local maximum point based on values Imoy and Qmoy.
