Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific examples.

[0022] as attached figure 1 As shown, a counting method and device based on machine vision, the counting method includes two levels: the main counting method and the differential counting method: set the counting target as N1, set a main counting value N2 close to N1 (N2<N1 ), to get N3=N1-N2 (101), and N3 is the differential compensation count value. The counting process is divided into two stages: the main counting (102) of N2 and the differential counting (103) of N3. The two-stage counting methods are equipped with exclusive feeding and vibration mechanisms: the main counting is equipped with a main counting feed hopper and a two-stage vibrating conveyor belt (104), and the differential counting is equipped with a differential counting vibrating plate and a transmission mechanism (105). The two-level counting method is based on the following reasons: due to the conside...

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 ...
