Abstract

The invention discloses an image processing method for diode counting, and the method at least comprises the following steps: extracting a diode image shot by X rays, and obtaining a to-be-processed image; performing first global threshold segmentation in the to-be-processed image according to the fixed threshold to obtain a first image; performing first connected domain combination on the first image to obtain a second image, and preprocessing the second image to obtain a third image; performing feature extraction on the third image to obtain a diode region image; performing global thresholdsegmentation and region number statistics on the diode region image to obtain the number N of diodes; wherein N is a positive integer greater than or equal to 1. According to the image processing method for diode counting provided by the invention, the defect that the traditional packaging counting consumes manpower and time can be solved, and the purposes of fast counting time and high precisionare achieved.

Description

technical field [0001] The invention relates to the field of machine vision counting, in particular to an image processing method and device for diode counting. Background technique [0002] In industrial production, due to the large number of chips and their small shapes, the traditional method of packaging and counting them is a very labor-intensive and time-consuming task. Using the traditional method to count diodes has the problems of slow manual counting, low precision and high labor intensity. Contents of the invention [0003] An image processing method for counting diodes provided by an embodiment of the present invention can solve the shortcoming of traditional encapsulation counting that consumes manpower and time, and achieves the purpose of fast counting time and high accuracy. [0004] In order to achieve the above object, on the one hand, the first embodiment of the present invention provides an image processing method for diode counting, which is character...
