Embodiment Construction

[0022] As shown in Fig. 1, the preferred embodiment of the present invention includes a sample cup position synchronous encoder, a lighting assembly, a 3CCD color camera, and an industrial control machine. The sample cup position synchronous encoder is installed at the lower part of the Vieri test thermostat, the lighting assembly and 3CCD color camera are facing the observation window of the Vieri test thermostat, and the industrial control machine completes the process according to the output signal of the sample cup position synchronous encoder. Image capture, signal processing, color recognition and other operations for the litmus paper sample cups at the corresponding positions in the Vieili test thermostat.

[0023]As shown in FIG. 2 , the sample cup position synchronous encoder includes an encoder disk 1 , a first photoelectric converter 2 and a second photoelectric converter 3 . The code disc 1 is a metal disc with a shaft hole, which is fixedly connected to the rotati...

Abstract

The present invention discloses a test paper color identification device in a Christian Vieri experiment, and comprises a sample cup position synchronous coder, a lighting assembly, a 3CCD color video camera and an industrial control machine which is programmed with an image processing and color distinguish software bag. The sample cup position synchronous coder is used to offer being location signal that the sample cup is just opposite to the observing window of a Christian Vieri experiment calorstat. A still image of the sample cup test paper which is just opposite to the observing window can be captured by the image processing and color distinguish software bag from the video output of the 3CCD color video camera, and the image is intercepted, calculated and identified. The color marker of the test paper in the sample cup at the current hour is finally obtained. The present invention has the main advantages that the influence which is generated by the brightness of illumination to the color identification is effectively eliminated. The precision is high, the speed is fast and the repeatability is good in the color identification. So the uncertainty of the fixed value in the Christian Vieri experiment is effectively reduced. The invention founds a base for the automatization of the operation of the Christian Vieri experiment and the quantitative transmission of the identified standard of the test paper color.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and mainly relates to a measuring device based on video image processing and applied to the automatic color recognition of gunpowder Vienna test paper. technical background [0002] Vieri test, also known as litmus paper test, is a basic method of gunpowder stability test based on nitrate ester. The principle is: put a certain amount of gunpowder sample into a Vieili sample cup with litmus paper to seal it, and put the sample cup into a thermostat at 106.5±0.5°C to heat it, and observe the decomposition and release of the sample. NO 2 The time it takes for the litmus paper to change the color of the test paper is used to judge the stability of gunpowder or nitrocellulose. The main advantages of this test method are stable results and high reliability. It has been used for nearly a hundred years, and it is still one of the main methods for judging the stability of gunpowder in many countr...
