<p>A method for inspecting without contact of the ends of the cigarettes, or similar,in where the conformation of at least one side of the ends of the cigarettes (S), that is the side of the end of the filter and/or the degree of filling with tobacco in correspondence to the end on the opposite side are detected by illuminating with a light source of preset intensity (306, 104) at least one zone (I) of the end of each cigarette and measuring the intensity of the light reflected (R1, R2, 204, 304, 406) by said illuminated zone (I). According to the invention, the intensity (I1, I2) reflected (R1, R2, 204, 304) by at least part of the illuminated zone of the cigarette end is surveyed seperately by at least two different angle shots. The measured value relative to the conformation of the end side of the cigarette or of the filter, that is at a distance of the zone (I) of the end or filter illuminated by the incident ray of the emitting source (104, 306) and/or by the surveying sensors or by a preset plane is obtained thanks to the elimination of the dependency on the colour of the tobacco through combination of the two measurement signals (I1, I2) proportional to the intensity. <IMAGE></p> |
