Abstract
A device for detecting the profile of a tread includes a light source, a mask configured for receiving a light emission of the light source and permeable to the light emission in correspondence of a slit provided therein. The slit is configured for generating, when traversed by the light emission, a light curtain. At least one image-acquisition device is configured for acquiring a projection of the light curtain on a tread, and a data-processing unit is operatively connected to the image-acquisition device for reception of image data acquired thereby.
Claims14
A device for detecting the profile of a tread, the device comprising:
- a non-collimated light source directed toward a mask,
- said mask comprising a slit, said mask configured for receiving a light emission from said light source and permeable to a portion of said light emission through said slit in said mask,
- said slit being configured for generating, when traversed by said portion of said light emission, a light curtain on a tread,
- wherein an angle of aperture of said portion of said light emission forming said light curtain is smaller than an angle od aperture of said light source upstream of said slit when the angle of said portion of said light emission forming said light curtain is measured in a plane traverse to a longitudinal dimension of said slit,
- at least one image-acquisition device configured for acquiring a projection of said light curtain on said tread, and
- a data-processing unit operatively connected to said image-acquisition device for reception of image data acquired thereby.
