Abstract:
A method of mapping a surface, the method comprising:scanning the surface using a single movable reference independent scanner assisted by a system controller comprising the steps of: during a first time period projecting a first image along a projection axis to an object to be mapped, the first image having a measuring feature, and capturing the reflection of said first image; and during a second time period projecting a second image along the projection axis to the surface, the second image having an encoding feature which is used to identify the measuring feature of the first image, wherein the first time period and the second time period are adjacent in time, and substantially mutually exclusive, and capturing the reflection of said second image; performing a registration of frames derived from captured reflections of said images; displaying the surface mapped from said registration enabling the scanner's operator in determining the areas where additional scanning is needed; and moving the scanner as necessary and repeating the above steps until the entire surface is mapped.
