PoE cameras Depth perception is a key feature of the DepthAl platform, which supports diferent methods of perceivingdepth:

1.Passive Stereo Depth-Used by non-Pro version of OAK-D cameras.

2.Active Stereo Depth-Used by Pro version of OAK-D cameras.

3.Time-of-Flight Depth- Used by OAK-ToF.

Passive stereo works similarly to human vision, Our brains estimate the depth of objects based on thedifference in perception between our left and right eyes. in OAK-D cameras, a stereo camera pair (left andright monocular cameras) performs a similar function. The VPU (Visual Processing Unit of the OAK camerasdoes disparity matching to estimate the depth. Disparity is the pixel distance between the same point in the left and right images of the stereo pair camera.The OAK-D camera calculates disparity for every pixel in the mono frame, assigning a disparity value withsome confidence level. This process occurs inside the StereoDepth node. The depth map is calculated fromthe disparity map using this formula.
