【摘要】 水中气泡的拍摄及后期的图像识别是两相流可视化PIV(particle image velocimetry)研究的主要内容之一。用自制装置,将连续脉冲固体强激光(功率200mW的DPSS 532nm)扩束后对称地布光,用CCD相机对水中气泡进行了拍摄,抓拍到一系列边缘较为清晰的水中气泡照片。通过图像处理技术对一幅水中气泡图像进行了针对性的处理,得到了清晰的单像素边界。总结出一套适用于水中气泡及其他两相流PIV图像处理的方法。更多还原

【Abstract】 The photograph and image processing is primary content of PIV (particle image velocimetry). The technology of light disposal and photograph was discussed. The continuous pulse solid laser (power is 200mW DPSS 532nm) after enlarging was used for illumination. After shooting of the air bubble in water with CCD camera, a series of photos with clear edge was acquired for processing of PIV. With the technology of image processing, a photos was pertinent processed, the clear onefold pixel edge was acquired. The technique can be used for image processing of PIV was summed up. The solving of this problem will powerful support the technology of PIV.更多还原
