iPhone X Vs Microsoft Xbox Kinect camera big showdown

According to James Consulting, Apple's new TrueDepth camera for the iPhone X is really impressive, but it sounds familiar. It works by projecting 30,000 points on a person's face using a dot matrix projector (infrared light emitter) and then reading it with an infrared camera. This sounds a lot like how Microsoft Kinect works.

The projection lattice Kinect used in structured light in 3D vision uses a variety of methods for obtaining high quality 3D images. There is a method called structured light - this is a projection of a known dot plot and uses machine learning to reconstruct a 3D scene. This method is done using an infrared light emitter and an infrared camera. The iPhone X camera works in a similar way. However, the conventional two visible light cameras can also be used to measure the depth of the stereo. Basically, the camera uses depth of field to estimate the distance of the object (if the object is farther or closer than the focus, it is blurred).

The main components of Microsoft Kinect Although Apple did not explicitly indicate whether the iPhone X uses a color image sensor, we think it does. The main reason is the presence of the Flood Illuminator, which allows the color camera to be visible in the dark (the infrared camera already has a dot matrix projector). Kinect has some other tricks. The lens is astigmatic, which means it has different horizontal focal lengths and vertical focal lengths. This gives it two readings per pixel, but it affects image quality.

The iPhone X original camera has similar components to Kinect. In any case, all data is passed to a machine learning system that has been trained in thousands of examples, such as body position in Kinect and iPhone X. Facial expressions.
