Acquisition of high speed camera and instrumentation suite for visualization and three dimensional field reconstruction

摘要本提案为购买一套由两台高速数码相机组成的仪器套件而寻求资金，该相机能够分辨三维位置、速度和加速度。这架照相机是经过特殊配置的，能满足各种需要。该系统的应用范围从解析0.1 m/s到800 m/s的移动现象，到解析米到亚毫米的分辨率的图像。两台幻影v7s相机能够以每秒4800帧（FPS）的速度捕捉800 × 600像素的图像，最高可达150,000 FPS。该方案包括3个镜头的成本：用于较大尺度物体的50mm和70-200mm变焦镜头和用于解析小尺度物体的KC型远距离显微镜。与相机耦合的显微镜镜头能够在4,800 FPS下产生0.0075 mm的分辨率；绰绰有余用于上述项目1、3、4和8的研究。捕获的图像将被输入到一个软件包Tema3D中，该软件包能够解析选定基点在相机视野中移动时的三维位置、速度和加速度。此功能对于解决上面列出的项目2、5、6、7和9所需的运动特别有用。三维功能需要两个摄像头。拟议的设备是便携式的，将在整个学年中几乎连续使用，用于研究、研究培训和教育目的。该设备每年将由9名高级教师，几名研究生和大约70名本科生在两个实验室中使用：测量和机电一体化实验室和热力学/流体/传热实验室。从这项投资中受益的研究项目由各种来源资助，从行业赞助商，如格林海克风扇，福特汽车公司，转子完成，罗克韦尔自动化和金百利克拉克到政府机构，如国家科学基金会和海军水面作战中心。其中两个项目代表了由马奎特工程学院和机械工程系赞助的本科生研究培训。这种能力的广泛影响是增强我们为学生提供新的教育和研究培训机会的能力，吸引外部行业参与，在几个研究项目中取得进展。

ABSTRACTThis proposal is seeking funding for the purchase of an instrumentation suite composed of two high-speed digital cameras capable resolving three dimensional position, velocity and acceleration. The camera is specially outfitted to make it of particular use over a wide range of needs. Applications for this system vary from resolving phenomena which move anywhere from 0.1 m/s to 800 m/s and resolving images to a resolution ranging from meters to sub-millimeters. The cameras, two Phantom v7s, are capable of capturing 800x600 pixel images at 4,800 frames per second (FPS), up to 150,000 FPS. This proposal includes the cost of 3 lenses: a 50 mm and a 70-200mm zoom lens for larger scale objects and a model KC long distance microscope for resolving small scale objects. The microscope lens coupled with the camera is capable of producing a resolution of 0.0075 mm at 4,800 FPS; more than adequate for the studies in this size range, projects 1, 3, 4 and 8 listed above. The captured images will be the input to a software package, Tema3D, capable of resolving three dimensional position, velocity and acceleration of selected fiducial points as they move through the cameras field of view. This feature is especially useful for resolving motion required by projects 2, 5, 6, 7 and 9 listed above. The three dimensional capability requires two cameras. The proposed equipment is portable and will receive near continuous use through the academic year both for research, research training and educational purposes. The equipment will be used by 9 senior faculty members, several graduate students and approximately 70 undergraduate students per year in two lab sections: Measurement and Mechatronics Laboratory and Thermodynamic/Fluid/Heat Transfer Laboratory. The research projects benefiting form this investment are funded through a variety of sources from industry sponsors such as Greenheck Fan, Ford Motor Company, Rotor Finish, Rockwell Automation and Kimberly-Clark to governmental agencies such as NSF and the Naval Surface Warfare Center. Two of these projects represent undergraduate research training sponsored by the Marquette College of Engineering and the Mechanical Engineering Department. The broader impact of this capability is to enhance our ability to provide new educational and research training opportunities to our students, attract outside industry participation, move forward in several research programs.
