Embedded system, fast structured light based 3d camera system and method for obtaining 3d images using the same

Abstract

Disclosed are an embedded system, a fast 3D camera system based on structured light, and a method for acquiring 3D images using the system. The embedded system includes a pattern generation module for generating the pattern in real time and a camera trigger module for converting a camera synchronization signal into a trigger signal and transmitting the signal to a camera. A transform module for transforming the pattern into a video signal and a communication module for receiving a command for projecting patterns and capturing images may be further included. The fast 3D camera system based on structured light includes an embedded system for generating a pattern in real time upon receiving a command for projecting patterns and capturing images, a projection device for projecting the pattern, and a camera for capturing the image of an object onto which the pattern is projected.

What we claim: 
     
         1 . A method for generating a 3D image of an object the method comprising:
 generating, by an embedded system, a pattern in real time in response to a command received from a computing device;   generating, by the embedded system, a camera synchronization signal;   converting, by the embedded system, the camera synchronization signal into a trigger signal; and   transmitting, by the embedded system, the trigger signal to a camera.   
     
     
         2 . The method of  claim 1 , further comprising:
 transmitting, by the computing system, the command to the embedded system via any one of a wired link and a wireless link.   
     
     
         3 . The method of  claim 1 , wherein the pattern is not stored in a memory of the embedded system. 
     
     
         4 . The method of  claim 3 , further comprising:
 transforming, by the embedded system, the pattern into a video signal; and   transmitting the video signal to a projection device to cause the projection device to project the pattern onto the object.   
     
     
         5 . The method of  claim 4 , further comprising:
 capturing, by the camera, an image of the object having the pattern projected thereon.   
     
     
         6 . The method of  claim 5 , further comprising:
 generating, by the computing device, the 3D image of the object from the captured image.   
     
     
         7 . The method of  claim 6 , wherein the method is performed a plurality of times according to an initial setup process.
