Abstract:
Disclosed are an apparatus and a method of compensating temperature shifts of a structured light pattern for a depth imaging system. In some embodiments, a depth imaging device includes a light source, an imaging sensor and a processor. The light source emits light corresponding to a pattern. A temperature drift of the light source can cause a shift of the pattern. The imaging sensor receives the light reflected by environment in front of the depth imaging device and generates a depth map including a plurality of pixel values corresponding to depths of the environment relative to the depth imaging device. The processor estimates the shift of the pattern based on a polynomial model depending on the temperature drift of the light source. The processor further adjusts the depth map based on the shift of the pattern.

Claim (Index 9):
The depth imaging device of  claim 1 , wherein the pattern is a light pattern corresponding to a reference image including a plurality of objects; and\n wherein the polynomial model includes a function set, each function of the function set being predictive of shifts of a corresponding object of the plurality of objects due to the temperature drift, the function set including a first function predictive of a shift along a first direction and a second function predictive of a shift along a second direction.
