基于LabVIEW的水平仪自动检测装置

LabVIEW-based development in automatic calibrators for the levels

结合步进电机驱动与图像处理技术,设计了一种基于LabVIEW和NI Vision的水平仪自动检测装置。采用高清摄像头读取目标图像信息,利用图像处理的方法实现图像的去噪与目标定位,实现微米级的分辨力,检测系统自动给出检测结果报表。利用LabVIEW的图形化语言,实现了软件设计的快速开发,降低了软件开发的难度。通过对图像采集系统及步进电机驱动电路的大量实验,证明了设计方法可靠实用,提高了检测效率,系统各个模块配合良好,可以准确可靠地得到检测数据,在实际工作中得到了很好的验证。

In this paper, by used stepper motor driver and image processing technology, a automatically calibrators for the levels designed, it based on LabV1EW and Ni Vision＇s. High definition camera to read the target image information, the use of image processing methods to achieve image denoising and targeting to achieve micron-level resolution, detection system automatically gives the test results report. Use LabVIEW graphical language to achieve a rapid development of software designed to reduce the difficulty of software development. Through the image acquisition system and stepper motor drive circuit a lot of experiments, proved reliable and practical design methods to improve the detection efficiency of each module with a good system, you can get accurate and reliable test data,and it has been proved in practical work.
