    Graduate What is a phase map and how is it used in structured light 3D scanners?

    Hmmm ... so in the context of measuring surface shape, would the phase map be a table of values (one for each pixel) giving the slope of the depth function (z = f(x,y))? Or perhaps the slope in a particular direction (probably the x direction)? Thanks

    Graduate What is a phase map and how is it used in structured light 3D scanners?

    What is a "phase map"? I am doing some reading on Structured Light 3D Scanners using digital fringe projection, where a projector shines light (e.g. sinusoidal patterns) onto an object, a camera takes some pictures, and some software uses them to extract a 3D model of the object. The papers...
