A method reducing errors in surface gradient calculation is presented. The method is independent of employed model of light reflection and therefore extends the spectrum of scanning surfaces. The error reduction is due to increase in number of images obtained with the technique similar to the HDR imaging. Effectiveness and optimal parameters of the proposed method are evaluated for two test objects with the use of computer modeling of the scanning process. An analytical model for reflection and five light source configuration are used.
