Infrared Projector
The infrared projector improves the ability of the stereo camera system to determine depth by
projecting a static infrared pattern on the scene to increase texture on low texture scenes. The
infrared projector meets class 1 laser safety under normal operation. The power delivery and
laser safety circuits are on the stereo depth module. The infrared projector is referred as
Standard or Wide based on field of projection.

Color Sensor
The color sensor on the stereo depth module in addition to color image provides texture
information. Usages for the texture information include overlay on a depth image to create a
color point cloud and overlay on a 3d model for reconstruction.
