The optical methods of coordinate measuring are a tool that have been more and more frequently used in biometrological applications, due to their advantages. The object of this paper is to set the accuracy of modelling solids of revolution whose shapes and measurements find their application in medical diagnostics with the use of three measurement systems employing laser and structured light. The carry out the studies, a coordinate measuring machine LK CMM with LC60Dx laser scanner, a coordinate measuring Romer Absolute Arm 7320SI with HP-L-20.8 laser scanner and an optical Scan 3D Qualify scanner were used. The use of coordinate technique to analyze the shape of the model solids allowed for the comparison of accuracy of optical methods with reference to standards digitally modelled based in measurements made by CMM Leitz PMM 12106. The most preferable contactless system to render the shape of solids of revolution is the LK CMM with LC60Dx laser scanner.
