Dynamic Intelligent Detection System for Crucible Bubbles Based on ARM

为了得到石英坩埚透明层气泡的形态参数及数量。搭建了一种基于ARM的石英坩埚气泡动态智能检测平台。首先利用STM32作为机械臂的控制单元,搭载电子放大镜采集坩埚气泡图像;其次对采集的气泡进行增强处理并且提出一种融合霍夫变换气泡轮廓提取算法,利用凹点提取分割算法分割重叠气泡。最后基于ARM开发了实时检测系统。实验结果显示,设计的系统对气泡信息定位准确,单张图像检测时间仅为0.1 s,实现了动态获取气泡直径、数量的功能。

In order to obtain the morphological parameters and number of bubbles in the transparent layer of the quartz crucible,a dynamic intelligent detection platform for quartz crucible bubble based on arm was designed.Firstly,STM32 was used to control the mechanical arm equipped with an electronic magnifying glass to collect the crucible bubble image.Secondly,the collected bubbles were enhanced and an improved bubble contour extraction algorithm was proposed,which used concave point extraction and segmentation algorithm to segment overlapping bubbles.Finally,a real-time detection system was developed based on ARM.The experimental results show that the designed system accurately locates the bubble information,and the detection time of a single image is only 0.1 s,which realizes the function of dynamically obtaining the diameter and number of bubbles.
