1. an equipment for the size and dimension of a plurality of sample object of selecting from ore, rock, gravel, aggregate natural, artificial or that reclaim for automatic analysis, this equipment comprises:

  • A) feed appliance unit, for the stream of isolated object is fed to travelling belt,B) light source, it projects plane collimated light beam on described travelling belt,C) image capture apparatus, comprises at least one visual detector, for catching the image to the reflection of the described plane collimated light beam of described object illumination,Control system, this set-up of control system has treating apparatus and the storer that wherein stores computer program, for controlling the machinery of equipment and hardware components and for storing the image of catching, this control system is adapted to process a series of images of described object, and automatically determine the size and dimension of described object, and the parameter of returning to the size and dimension that represents this object, described form parameter comprises the parameter of indication profile and corner angleWherein said control system is adapted to process image sequence, and example is learned algorithm, to calculate angular volume value, and poor between the depth image of reflection particle surface and morphology opening, described angular volume value and circularity or corner angle parameter correlation.
