Abstract

The invention relates to a method and device for detecting the position of a filling material in a pipe, and the method comprises the steps: selecting a first pipe, a second pipe and a third pipe, which are all provided with the filling materials; respectively carrying out the image collection of the first, second and third pipes under the same image collection condition, so as to respectively obtain a first image, a second image and a third image; calculating the statistics parameter Em of the attribute information of the first and third images and the statistics parameter Ep of the attribute information of the second and third images; carrying out the image collection of a to-be-detected pipe, so as to obtain a fourth image, wherein the to-be-detected pipe is the same as the first, second and third pipes and has the filling material; calculating the statistics parameter Ew of the attribute information of the third and fourth images; comparing Ew with Em and Ep, and determining whether the height of the filling material in the to-be-detected pipe accords with a preset standard or not according to the comparison result of Ew, Em and Ep. The method improves the detection efficiency of the position of the filling material in the pipe.

Description

Technical field [0001] The present disclosure relates to the technical field of industrial detection, and in particular to a method for detecting the position of a filler in a tube and a device for detecting the position of the filler in a tube. Background technique [0002] In daily life and work, pen applications can be seen everywhere, and the signature pen is more and more popular with users due to its own advantages such as ink filled, smooth and labor-saving writing, and good writing effect. [0003] At present, in the pen industry, judging whether certain pen standards are qualified or not still relies on manual testing. Specifically, when detecting whether the height of the air, tail plug oil, and ink in the non-transparent refill meets the standard, it is necessary for the inspector to perform the inspection by visual observation or using special inspection tools (such as some hand-held inspection tools). The main shortcomings of this detection method are: on the one hand...
