Microsoft's Kinect was designed first and foremost for Gaming, but the camera it uses offers reliable detection depth which has led several navigation systems to use it. Soon, however, Microsoft's technology may face strong competition. THE MC3D is here.
The University of Northwestern designed the Motion Contrast 3D Scanning Camera (MC3D), which is very economical and offers higher quality imagery. The impressive thing is that it has the ability to work in the sunlight as well.
Kinect works by displaying a grid of infrared light spots on a scene. Then it measures the time it takes light from each of these points to turn back (reflection) into the sensor of the camera sensor.
Τα περισσότερα επαγγελματικά συστήματα μπορούν να έχουν pictures υψηλής ανάλυσης, χρησιμοποιώντας ένα μόνο λέιζερ, που σαρώνει πέρα δώθε μια σκηνή. Εξαιτίας αυτού, τα συστήματα αυτά παρεμποδίζονται από κινούμενα αντικείμενα.
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 only record if there is one change to your visual stimulus. We realized that this principle could be really useful for a 3D scanning 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.
