However, when the glass gauge capacity automatic verification device is used, it is necessary to manually place the glass gauge to be tested in the fixed fixture, and then implement the automatic verification process. It can be seen that it is still impossible to realize full automation, and a certain amount of labor cost is wasted.

The invention belongs to the technical field of machine vision, and discloses a glass measuring vessel automatic calibration system and a control method and device. By arranging a carrying system comprising a mechanical arm, the mechanical arm can be automatically controlled to grab a glass measuring vessel located in a to-be-detected area and carry the glass measuring vessel to a detection area of the calibration system; then the calibration system is controlled to automatically calibrate the glass measuring vessel located in the detection area, and after the automatic calibration is completed, the manipulator is controlled to grab the glass measuring vessel located in the detection area and carry the glass measuring vessel to the detection completion area, so that the glass measuring vessel can be automatically grabbed and moved, the glass measuring vessel is automatically calibrated, the glass measuring vessel to be detected does not need to be manually fixed, the labor cost can be reduced, and full automation of the calibration process of the glass measuring vessel is achieved.
Description
technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a glass gauge machine vision automatic calibration system, a control method and a device. Background technique [0002] A glass measuring device is a measuring tool used to measure the volume of a liquid, such as a graduated cylinder, volumetric flask, etc. In the inspection and testing industry, glass gauges need to be calibrated regularly to determine the accuracy of their measurements. The calibration method is to use the weighing method, that is, to obtain the accurate mass of the liquid in the glass measuring vessel through the balance, and then use the mass-density formula M / ρ conversion to obtain the accurate volume V of the liquid under the premise of known liquid density 0 , and finally read the measured value V of the glass gauge, and calculate V minus V 0 The difference is taken as the measurement error of the glass gauge. It follows that the cali...
