The trench in the Bruszczewo scene has an extension of approximately 3 x 4 m. The measured distances vary between
0.1 m and approximately 1 m. Table 1 shows the resulting average measurement errors, which are very small (below 10 mm). Note that the experimental set-up is different from the one described in section 3.1. To enable comparison with ground truth data, the results for the synthetic scene are given in table 1 as well.
