摘要:
介绍了一套利用CCD摄像头在LabVIEW平台上开发出的水液滴喷射图像采集及分析系统，具有稳定可靠、应用灵活等优点。该系统通过调用动态链接库驱动摄像头完成图像采集，实时监测液滴的运动情况，再利用 IMAQ Vision完成图像的批量存储。保存的液滴图像将由MATLAB软件进行分析处理，得到液滴大小、位置、间距等参数，可以定量地评估液滴喷射的质量和稳定性。实验采用80 μm孔径金属喷嘴喷射出重复频率30 kHz的水液滴靶材，CCD摄像头以5 Hz频率采集到水液滴图像。图像经批量分析后可得出液滴直径约188 μm，液滴之间平均间距约562 μm，且各自标准差较小，液滴在喷射过程中能够稳定且均匀断裂。
Abstract:
a set of?water droplet jetting?image acquisition and?analysis system using CCD camera?on the platform of LabVIEW is proposed,?with the advantage of?stable and reliable performance and agility?for?application. The system?drives the?camera by calling the dynamic link library to complete the image acquisition,?real-time?monitoring?the movement of?droplets, and then uses IMAQ?Vision?to store the images. The droplet images will be?analysed by the MATLAB software,?obtaining the?droplet size,?position,?spacing?and other parameters,?which can be used for quantitatively?evaluating the quality and?stability of liquid droplet jetting. The experiment uses the 80 μm?diameter metal?nozzle and pure water as liquid material, with the repetition frequency of 30 kHz. The frequency of CCD camera to capture images of water droplets is 5 Hz. Analysis of the images indicates that the droplet diameter of about 188 μm, the average spacing between the droplets is about 562 μm with small deviations. Therefore,?droplets can be jetting in?stable and uniform?condition.
