A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.

Speed measurement using time-of-flight sensing and anti-collision protection using time-of-flight sensing

In an embodiment a method for detecting a presence of at least one object in a field of view of a time of flight sensor includes successively generating, by the time of flight sensor, histograms, each histogram comprising several classes associating a number of photons detected at a given acquisition period, adding several successively generated histograms so as to obtain a summed histogram and analyzing the summed histogram to detect the presence of at least one object in the field of view of the time of flight sensor.
