TOOLS MEASURE DISTANCE
How Do I Accurately Measure the Contours of a Surface From Distance ?
I know various electronic measuring devices exist to give the distance of a surface from the measurer. Such as hand held surveying tools etc using a laser beam etc.
But is it possible to get a very accurate measurement of an entire rugged surface of a structure from a distance of several metres away ? Such as the surface of a rock face or the carved wall of a building ?
This is actually relatively easy and the technology is used in several industries, notably the automobile industry.
Essentially, you use an optical projector to project multiple parallel line, scattered dot or more complex encoded patterns on the surface. These projected patterns are then picked up by multiple cameras and a computer calculates the surface from the distortion of the patterns.
In case of parallel stripes a flat surface will reflect parallel stripes. If the surface is curved, the stripes will appear closer in some places and wider apart in others. From that one can calculate the local angle of the surface relative to the projecting beam and from that, by integration, the absolute contour. But there are much more advanced test patterns than that.
