System and method for collecting and identifying images of capillary pipe liquid level type data

Abstract

The invention provides a system and a method for collecting and identifying images of capillary pipe liquid level type data of a measuring instrument, which are used for intelligently reading and recording the capillary pipe liquid level type data needing to be manually read in the measuring instrument. The system for collecting and identifying the images of the capillary pipe liquid level type data in the measuring instrument comprises a liquid level shooting device, a bar code scanning module, a data transmission module, a computer, an image processing system, a client user interface module, a database and a monitoring module. The system and the method have the advantages that the liquid level shooting device which can be closed is fixed in the capillary pipe liquid level position of the measuring instrument by a movable clamping mechanism, and an image is shot under the control of the bar code scanning module when a camera and a bracket are not touched, so the liquid level image can be obtained without dithering and interference by other object images, and the intelligent identification difficulty of the liquid level data is reduced.

Description

technical field [0001] The invention relates to a method and device for image acquisition and recognition of liquid level data in a measuring instrument, and belongs to the technical field of intelligent measurement, in particular to an image acquisition and recognition system for thin tube liquid level data in a measuring instrument and method. Background technique [0002] The capillary liquid level data is the quantitative data determined by comparing the liquid level of the liquid in the capillary with the accurate scale on the capillary. The most typical is the titration volume. There is an accurate volume scale on the burette. The relationship between the liquid level and the volume scale can determine the volume data corresponding to the liquid level. [0003] With the rapid development of image sensing technology and computer technology, the computer intelligent recognition of liquid level measurement has also been greatly developed. There are many researches on key...

AI Technical Summary

Problems solved by technology

[0012] However, in the teaching experiment, there are some problems in the reading record of the thin tube liquid level in the measuring instrument. For example, the experimenter sometimes misreads the liquid level data due to unfamiliarity with the experiment, and sometimes because of the subconscious To "rely on the last measurement data" will cause the error of reading data to become larger, and sometimes the liquid level data will be read intentionally and incorrectly. Because these data are read frequently in the experiment, the experimental instructors cannot do it Calibration verified for each level data

This situation is very unfavorable for evaluating the experimental performance of the experimenters and improving the experimental ability of the experimenters
