Dense High Speed 3D reconstruction method By One-shot technique
Shape  measurement technique can restore the shape of a one-shot
technique using a single image, which has been studied as sitable for measuring the shape of fast moving objects in motion.
In this study,conducted in a 3D reconstruction of moving objects technique using a one-shot for the high-speed camera and projector.
  Projected pattern consists of a set of parallel lines on the surface to achieve high-density shape reconstuction.This could be restored to almost exactiyat the moment dropped the ball splashes and ripples.

 If we can obtain three-dimensional shape of moving objects very fast with a high frame rate and high dense, it can significantly contribute to analysis of many objects and prevention accident.
  In this study,we used method which interesectionn of the grid pattern using high-speed cameras and projectors,and streamline ray detection efficiency due to Debruin and belief-propagation.
This solves the problem of one-shot scan measurements become sparse and dense pattern is not available , and successfully acquired the shape of the movement of the moment break a balloon at more dense and high frame rate.
