Figure 9. Histogram of 3500 measured distances
Note: The mean of the measured distances, in case it equals the real distance between the sensor and the floor, is an
indication of the reliability of the setup.
In Figure 10. Reliable setup, the mean of the measured distances from the two zones are the same and equals
the real distance between the sensor and the floor, which is 2600 mm. This indicates a reliable setup. Here, the
threshold is less than 1920 mm.
