Light Field Based Optical Measurement System and Its Application

在该项目中，设计了具有最佳照明光场和最佳相机设置的光学测量系统，以测量手指表面和鱼等物体的三维形状。该系统使用LED照明设备，其根据光的发射方向发射具有不同光谱带的光。利用该照明设备，通过具有光谱带滤波器的标准相机利用光谱信息来区分光的方向，并且照明系统的光场被用于提高观察物体的三维形状的精度和效率。此外，对于该项目的下一阶段的发展，该系统的有效性进行评估的运动物体的检测和估计其在三维空间中的运动。

In the project, the optical measurement system with the optimal light field for lighting and the optimal camera setting was designed to measure the three dimensional shape of objects such as a finger surface and fish. The system uses LED lighting device that emits light with different spectrum band depending on the emission direction of the light. With this lighting device, the direction of the light is distinguished with the spectrum information by the standard camera with the spectrum band filters and the light field of the lighting system is used to increase the accuracy and efficiency of the observation of the three dimensional shape of the object. In addition, for the development for the next stage of the project, effectiveness of the system is evaluated for the detection of moving object and for the estimation of its motion in the three dimensional space.
