Structured Light 3D Reading

: Structured Light 3D Scanner The same technique used for Thom's face in the Radiohead "House of Cards" video. ThreePhase .Triangulation via Inherent FeaturesMost 3D scanning will be based upon triangulation (the exception being period of flight systems like Windows "Natal"). Triangulation works on the basic trigonometric principle involving taking three measurements on the triangle and Nike Roshe Run Woven Black Nz using those to restore the remaining measurements.If we require a picture of a small bright ball from two views, we will get Beats Dr Dre Wireless two viewpoint measurements (based on the position in the ball in the camera's graphics). If we also know the distance between the two cameras, we have not one but two angles and a side. This permits us to calculate the length to the white ball. This is one way motion capture works (a great deal of reflective balls, lots of camcorders). If we know the angle of your laser pointer, that's a single Michael Kors Bag Singapore Price angle. The other comes from the camera again, except we're seeking a laser dot instead of a white ball. The distance between the beam of light and camera gives us the inside, and from this we can compute the distance to the laser department of transportation.But cameras aren't tied to one point at a time, we could check out a whole line. This is the reasons for systems like the DAVID Animations Scanner, which sweep a line laser across the picture.I have a doubt related to visual triangulation: I have to compute the matches of center of projection of camera sensor,that requires me to know it's sensor size since photographic camera calibration gives me the distance between Pandora Stockists Dunedin warning camera lens but in regards to no. of pixels each unit length along Times along Y direction.
