Actual combat | inductance element positioning -- detailed explanation of Halcon and opencv implementation (with source code)

Reading guide

In this paper, we share an example of inductor positioning , Attached Halcon and OpenCV Implementation steps and code .( official account ：OpenCV And AI Deep learning )

Background introduction

    This example comes from EmguCV Student exchange group , I have agreed to use pictures for demonstration .

As shown in the figure above, the coil inductance element , The goal is to locate the central position of the component and then grasp it with a manipulator , The accuracy requirement is not very high , However, due to the influence of coil lines , The matching effect is not very good , It's used for demonstration here Blob Analytical method to locate . The end result is as follows ：

Implementation steps and demonstration

【1】 Turn to grayscale + Two valued ：

【2】 Hole filling ( Refer to the following historical articles )：
