Comparison of 3D Scanning and 3D Modelling of a Workplace from Various Aspects

The paper investigates differences in data gathering and preparation of the workplace environment for virtual ergonomic analyses. The two investigated scenarios are classical digitization of the workplace by measurement of dimensions and subsequent modelling of the workplace in 3D drawing software compared to3D scanning of the workplace by an industrial scanner. Those two scenarios are assessed in terms of time and accuracy. The 3D scanning method was, on average, four times faster than 3D modelling and also more precise. However, the quality of the 3D model was better than the model obtained from the scanner. The need for accuracy in ergonomic analyses is also discussed in the paper.
