<P>PROBLEM TO BE SOLVED: To provide a large lump to be conveyed detecting system capable of properly detecting a large lump to be conveyed. <P>SOLUTION: A large lump muck detecting system 1 has a belt conveyer 10 having a belt 12 for conveying muck 2, an illumination part 30 irradiating light to the muck 2 on the belt 12, an imaging part 40 imaging the muck irradiated with light at plurality of times spacing times, and a large lump muck detecting part 53b for detecting the large lump muck based on the first image imaged at the time t1 when light is irradiated to the muck from one direction and the second image imaged at the time t2 (>t1) when light is irradiated to the muck from another direction by the running of the belt 12, the large lump muck detecting part 53b, when the a speed of the belt 12 is v, carries out the positioning of the first image and the second image based on v" (t<SB POS="POST">2</SB>-t<SB POS="POST">1</SB>), generates a logical multiplication image of the first image and the second image, and detects the large lump muck from the logical multiplication image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
