Nowadays, a number of 3D shape measurement methods have been developed such as stereo vision, laser structured light, and Phase Measuring Profilometry (PMP). They have many problems such as correspondence problem, 2π-ambiguity and occlusion problem. Among them, occlusion problem is common problem for 3D shape measurement and well known as difficult to solve. To solve this problem, in our previous...

Visually guided assembly of micro MEMS parts with high magnification is limited by small field of view (FOV). To overcome this problem, zoom lens system is usually adopted, which causes size change of the parts in the image space. Micro MEMS parts have several arbitrary planar shapes because of the fabrication process, so that contour to be described by control point can be suitable image feature...
Intelligent autonomous mobile robots must be able to sense and recognize 3D environment for navigation and task execution where they live or work. To achieve this, a variety of techniques have been developed for the determination of the 3D geometric information such as stereo vision, laser structured light, laser range finder and so on. However, these methods have several limitations such as susceptibility...
Automatic PCB (printed circuit board) assembly technique plays a very important roll in modern industry where electronics is becoming an indispensable part. Each process of assembly requires well-developed inspection technique to ensure quality of the products and prevent waste of resources. In the case of chip mounting inspection, a number of 2D inspection techniques have been developed but there...
Intelligent autonomous mobile robots must be able to sense and recognize 3D environment for navigation and task execution, where they live or work. To achieve this, a variety of techniques have been developed for the determination of the 3D scene geometric information such as stereo vision, laser structured light, laser range finder and so on. But these methods have many limitations such as susceptibility...
