Abstract:
1. Method for measuring the distance of an object from a measuring device, comprising the following steps: a) emitting a signal, wherein the emitted signal is a light beam adapted to illuminate the object along an emission optical path and said emitting step includes carrying out at least one scan on the object along at least one scanning line; b) directing the signal towards an object; c) detecting a signal diffused by the object, wherein the detected signal is an analogue electric signal representative of the luminous image diffused by the object along the scanning line; d) carrying out a sampling of an analogue electric signal representative of a distance travelled by the emitted signal and the object diffused signal, so as to extract at least one sample x e) wherein, prior to carrying out step a) there is a measuring device calibration step so as to associate at least one calibration sample x f) identifying the prefixed distance value associated, in the previous calibration step, with the numerical value of said at least one sample x g) associating the prefixed distance value identified in step (f) with the numerical value of said at least one sample x
