Το Kinect της Microsoft σχεδιάστηκε πρώτα απ ‘όλα για gaming, αλλά η κάμερα που χρησιμοποιεί προσφέρει αξιόπιστο βάθος detectionwhich has led several navigation systems to use it. Soon, however, technology of Microsoft, may face strong competition. THE MC3D is here.
The University of Northwestern designed the Motion Contrast 3D camera Scanning (MC3D), η οποία είναι πολύ οικονομική και προσφέρει απεικονίσεις υψηλότερης quality. The impressive thing is that it has the ability to work even in sunlight.
Kinect works by projecting a grid of infrared light points onto a scene. It then measures the time it takes the light from each of these points to bounce back (reflection) to the camera sensor chip.
Most professional systems can have high resolution images, using a single laser, scanning back and forth a scene. Because of this, these systems are obstructed by moving objects.
The MC3D, however, follows a completely different approach to the scanning laser. At first it stores a scene and evaluates the three-dimensional depth of all the objects within it. The laser then scans only the areas where visual changes are detected (if detected).
This way is similar to how the human eye works.
"If you send the same message over and over again, the neurons will stop caring," says Professor Oliver Cossairt, head of the program.
“Neurons record only if there is a change in your visual stimulation. We realized that this principle could be really useful for a 3D scan system. ”
In addition, because the laser is so bright that the MC3D can be used outdoors in bright sunlight. In contrast, with Kinect infrared lasers that do not work on sunny surfaces.
See the system in the video below.
