Infrared and non-infrared channel blender for depth mapping using structured light

A method for processing an image, comprising:

• receiving infrared image information for a three-dimensional area;
• receiving non-infrared image information for the same three-dimensional area;
• performing nonlinear intensity adjustment for the received infrared image information;
• performing nonlinear intensity adjustment for the received non-infrared image information;
• blending the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information to obtain monochrome merged image information including obtaining a weighted sum of the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information;
• and
• subsequent to blending the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information, providing the monochrome merged image information for determining a depth map.

A non-transitory computer readable storage medium storing instructions, which, when executed by one or more processors of an electronic device, cause the electronic device to:

• receive infrared image information for a three-dimensional area;
• receive non-infrared image information for the same three-dimensional area;
• perform nonlinear intensity adjustment for the received infrared image information;
• perform nonlinear intensity adjustment for the received non-infrared image information;
• blend the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information to obtain monochrome merged image information including obtaining a weighted sum of the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information;
• and
• subsequent to blending the intensity-adjusted infrared image information and the intensity-adjusted non-infrared image information, provide the monochrome merged image information for determining a depth map.
