A method and apparatus for uniform material counting based on machine vision

Abstract

The invention discloses a uniform material counting method and a device of machine vision, comprising two levels of a main counting method and a difference compensation counting method: a counting target as N1 is set, a target value N2 (N2<N1) close to the counting is set, and N3=N1- N2 is obtained, the counting process is divided into two stages: the main counting of N1 and the difference counting of N3. The counting device based on the method comprises a feeding module, a frequency adjustable vibration module, a machine vision counting module, a motion control module, a discharging module and an industrial control computer, wherein the counting device realizes the high-speed, high-accuracy and high-real-time counting of uniform materials, so as to overcome the defects of the traditionalmanual counting and the counting of the photoelectric equipment.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a machine vision counting method and device for hardware, electronic components, tablets, seeds and other uniform materials. Background technique [0002] In manufacturing, electronics, agriculture, medicine, food and other industries, uniform materials such as hardware, electronic components, seeds, and tablets need to be accurately counted. At present, there are two counting methods: the first is the manual counting method. Due to long-time counting, it is easy to cause extreme eye fatigue, which seriously affects the efficiency and accuracy of detection. In the occasions that require fast and accurate counting, its limitations more prominent. The second is to use photoelectric equipment to count. This method is harsh on the counting conditions of materials. It requires a single material and a gap to count accurately, otherwise the data will be inaccurate. It can be seen that ...
