| 摘 要： | 水中上升气泡的体积变化率是舰船自消隐特种气幕技术等诸多研究的重要基础。鉴于当前对这一体积变化率研究的紧迫需求,提出并较为深入地研究了水中上升气泡体积变化率的图像分析技术。首先,在理论研究的基础上,专门建立了分析计算的数学模型;进而给出了分析的实施方法,即利用摄像法获取水中上升气泡的图像序列,并从中得出所需图像的相关信息,再利用建立的模型即可求出其体积变化率;同时,设计了专门的实验,初步验证了这一分析技术的可行性。

| Abstract: | The volume changing rate of rising bubble in water is the research foundation of auto-dissolve bubble curtain for warship and the other fields.A new calculative method about volume changing rate of rising bubble in water which is based on image parameters was put forward.Its special mathematic model was set up on the basis of the theory analysis.And the method to obtain the parameters of serial images of rising bubble in water was studied and it is based on photography.Then the volume changing rate of rising bubble in water can be calculated by the mathematic model.The feasibility of the method was also validated by a corresponding experiment. |
