The 3D measurements of the human body surface or anatomical areas have gained importance in many medical applications. Three dimensional laser scanning systems can provide these measurements; however usually these scanners have non-linear variations in their measurement, and typically these variations depend on the position of the scanner with respect to the person. In this paper, the Levenberg–Marquardt method is used as a digital rectifier to adjust this non-linear variation and increases the measurement accuracy of our 3D Rotational Body Scanner. A comparative analysis with other methods such as Polak–Ribire and quasi-Newton method, and the overall system functioning is presented. Finally, computational experiments are conducted to verify the performance of the proposed system and its method uncertainty.
► We present a novelty to improve resolution of 3D Laser Dynamic Triangulation Scanner.
► We modeled three data processing methods to improve biometrical measurement quality.
► Examines changes in the implementation of these three methods on real data processing.
► Quasi-Newton, Polak–Rebiere and Levenberg–Marquardt methods were cross-compared.
► On 3D biometrical data processing, Levenberg–Marquardt shows the best reliability.
