Device and method for counting overlapped circular particulate matter

Abstract

The invention relates to a device and a method for counting overlapped round particulate matter, which aims to obtain higher counting precision and improve counting efficiency. The device for counting overlapped round particulate matter comprises a CCD camera, a DSP data processing system and an LCD, wherein the CCD camera is used for acquiring particle images and sending image signals into the DSP data processing system; the DSP data processing system comprises a DSP data signal processor, converts analog images acquired by the CCD camera into digital image signals, realizes image processing algorithm of a text, finishes counting particles, and displays counting results; and the LCD is connected with the output of the DSP data processing system, and is used for displaying acquiring original images of the particles and results after segmentation and outputting counted quantity of the particles.

Description

technical field [0001] The invention relates to image processing technology, in particular to an image recognition device and a counting method based on machine vision, which are realized by a DSP (digital signal processor). Background technique [0002] For the counting of round-like particles, the traditional method is to determine the number of round-like particles (such as crop seeds, cells, etc., hereinafter referred to as particles.) through human judgment. Since the human eye is prone to fatigue after long-term high-intensity work, the counting is accurate Sex is hard to guarantee. With the development of photoelectric technology, this counting method will eventually be replaced by more advanced counting methods. The photocell counting method makes full use of the photovoltaic effect of the photocell, that is, the photocell can reflect the change of the luminous flux through the change of the intensity of the photocurrent. After the instrument is turned on, the ligh...

Problems solved by technology

However, the photocell counting method has the following two disadvantages: (1) The sensitivity of the photocell is easy to attenuate and age, the replacement cycle is short, and the cost is high; (2) A single photocell is generally used for counting on site. In the case of local crossover, its output pulse will be lost, which will lead to the phenomenon of under-counting and missing-counting, and the accuracy is not high
