We apply our proposed method to inspect a complex three-dimensional die-cast product. Our approach recognizes the difference between two data sets as a defect after matching the data sets. Moreover, our method improves matching accuracy by detecting geometrical features such as edge points, and by using such property values as gradients. Fundamental experiments using real three-dimensional dot cloud data show that the method is effective as a defect inspection system.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

The constructed sensor consists of only commercially available products: a monochrome CCD camera, a color CCD camera, a laser projector, and two optical filters. The resolution of the range image is 19×19 for a total of 361 points, and the measurement speed is 100Hz. A three-dimensional (3D) mapping method using the constructed sensor is introduced. The measurement precision of the sensor and the accuracy of the constructed 3D map are evaluated with some experiments. In addition, measurement examples of the sensor are shown. Experiments verify that the constructed sensing system can acquire 100Hz real-time textured range images and that it can be applied to 3D mapping by using range and color information.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

Many of these pathologies require invasive biopsy procedures to verify the presence and stage of disease progression. Once identified the patient must then undergo treatment, where current imaging techniques lack the resolution for treatment monitoring that can be correlated to the gold standard of disease-free survival, namely histology. Optical coherence tomography is an exciting, high-resolution (∼10μm) non-invasive, imaging modality that may provide solutions to these problems and aid in the early detection and treatment monitoring of diseases. As the technology matures there is great potential for optical coherence tomography to become a clinical tool to aid in the clinical decision making process in an effort to properly provide patient risk stratification and subsequent appropriate therapy. In this article we present potential solutions to existing technical hurdles and speculate on future clinical implementation.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

At first, we verified the distribution of disparity error under the circumstance without the camera vibration and with the camera vibration. As the result, we found that we can approximate the distribution of disparity error by normal distribution under the circumstance without camera vibration and with camera vibration. And, the parameters of normal distribution are changed by the camera vibration. The parameters of the distribution of the measurement error are average μ and standard deviation σ. The parameters of the camera vibration are considered amplitude A and frequency F. In order to verify relationships during the parameters of the distribution of measurement error and the parameters of the camera vibration, we experimented using the vibration testing system. We imposed simple harmonic motion to the stereo camera. In this paper, we use stereo camera Bumblebee. As the result of experiment, the camera vibration didn't affect average μ. We found positively correlation between standard deviation σ and amplitude A. And, we found negatively correlation between standard deviation σ and frequency F. We estimate the parameters of measurement error by the parameter of the camera vibration using these relationships. So, we establish the error model of the stereo measurement system. Moreover, we define existing probability of object using the parameter of measurement error.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

Various tools such as electrical probes and force sensors have been designed and integrated on both high precision mobile micro-robots and fixed manipulators in order to interact with micro-objects. The platform enables the user to characterize parts with sizes ranging from sub-micrometer up to the millimeter. Forces ranging from 1 mN up to 120 mN can be measured as well as electrical resistivity of microcomponents. As the characterization platform is aimed to be used by material scientists and biologists, the manipulation is \"assisted\" so that the user focuses on the application and not on the robotic systems. One of the key features is that the control software will automatically bring the end-effectors of the manipulators in the local (microscope) field of view. The platform is composed of an XY stage mounted on an inverted optical microscope, of manipulators (fixed and mobile) and of various sensors (optical, force and electrical).","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

However, they have its own limitations : 2π ambiguity, correspondence problem, long estimation time. To solve these problems, in our previous researches [9,13], we introduced a novel sensing method adopting stereo vision and PMP technique (stereo PMP algorithm). One other difficult problem is occlusion problem needed to tackle by the stereo PMP algorithm which uses the principle of stereo vision and two cameras. The occlusion problem cannot be solved by using the principle of typical stereo vision, because there is no correspondence point in occlusion area. In our previous research based on stereo PMP algorithm, however, phase information related to the projector's position is additionally used which gives more additional information. By using this additional information, we can solve the occlusion problem effectively. In order to detect occlusion area, we adopt the principle of Dynamic Programming, while to measure the depth the principle of typical PMP algorithm and the geometrical relationship of detected depth area. To verify the efficiency of the proposed method, a series of experimental tests were performed.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].
