Referring to a Hungarian Government supported healthcare project "Intelligent tool and methodology to monitor and safeguard childhood spine deformities" (SPINE GUARD) the Department of Mechatronics, Optics and Information Engineering at Budapest University of Technology and Economics developed a new complex optical measuring equipment built up a projector and a digital camera. If the computer controlled projector projects an equidistant grid of lines then the camera takes a picture from a different position about the object to be measured and with a special software removing the grid lighted background there will be a virtual Moiré effect. After some picture processing the 3D (2,5D) reconstruction is finished. In an other working way the projector lights a rainbow on the object. The edges of the rainbow lines cut the crosssection of objects. An other special software reconstructs the 3D (2,5D) objects from the camera captured cross-section curves. Presentation is about the principle of measuring and evaluation of results and precision.
