1. A light source for structured light, comprising a plurality of light source elements arranged in an array, wherein the light source elements are configured to be driven in the following two modes:
a calibration mode, wherein only a part of the light source elements are adapted to be driven to generate a calibration pattern, and the rest of the light source elements are deactivated; and
a normal mode, wherein the rest of the light source elements are adapted to be driven to generate a normal pattern.
