Method and system for detecting liquid level of liquid medicine in complex scene

Abstract

The invention discloses a method and a system for detecting the liquid level of liquid medicine in a complex scene. The method comprises the following steps of: A, setting a light source, a light source illumination direction and an illumination mode; b, setting a camera, a camera lens and camera internal parameters; c, collecting images of the medicine bottle based on the steps A and B; d, labeling the liquid level of the liquid medicine in the collected image of the medicine bottle through an image labeling tool, and taking the labeled data as a data set; e, performing model training on the data set through the yolov5 to obtain a detection model; and F, detecting the liquid level of the liquid medicine in the to-be-detected image by using the detection model to obtain a liquid level detection frame of the liquid level of the liquid medicine, and judging whether the liquid medicine in the medicine bottle in the to-be-detected image is excessive or insufficient and whether the medicine bottle is insufficient according to the liquid level detection frame and the liquid level upper and lower limit values. The invention provides a method for detecting the liquid level of liquid medicine in a complex scene to solve the problem that a traditional image processing method cannot adapt to liquid level detection of the liquid medicine in the complex scene.

Description

technical field [0001] The invention relates to the technical field of liquid level detection, in particular to a liquid level detection method and system for a complex scene. Background technique [0002] In the traditional liquid medicine filling process, the liquid level height of the liquid medicine is usually manually measured by hand. With the continuous expansion of production scale, the efficiency of manual methods is low, so the demand for automatic liquid level detection is increasing. At present, there are liquid level detection methods such as photoelectric sensor detection, ultrasonic detection and machine vision liquid level detection on the market, among which machine vision liquid level detection is a non-contact and non-destructive detection method. It has the advantages of high efficiency, high detection accuracy, and simple equipment maintenance, and is widely used in liquid level detection projects. [0003] At present, traditional image processing meth...
